a cube has 2 faces painted red, 2 painted white, and 2 painted blue. what is the probability of getting a blue face or a red face in one roll? (enter your probability as a fraction.)

Answers

Answer 1

Therefore, the probability of getting a blue face or a red face in one roll is 2/3.

A cube has six faces, and we know that two of these faces are blue and two are red. Therefore, there are a total of 4 faces that are either blue or  red.

To calculate the probability of getting a blue or a red face in one roll, we can use the formula:

P(blue or red) = P(blue) + P(red)

The probability of rolling a blue face is the number of blue faces divided by the total number of faces, which is 2/6, since there are 2 blue faces out of a total of 6 faces. Similarly, the probability of rolling a red face is also 2/6.

So, substituting these values into the formula, we get:

P(blue or red) = 2/6 + 2/6

= 4/6

= 2/3

Therefore, the probability of getting a blue or a red face in one roll of the cube is 2/3.

what is 3 644 mod 645

Answers

The answer to 3 644 mod 645 is 3.

To solve this problem, we need to find the remainder when 3644 is divided by 645.

We can start by dividing 3644 by 645:
3644 ÷ 645 = 5 with a remainder of 319 This means that 3644 can be written as:
3644 = 645 × 5 + 319
To find the remainder of 3644 mod 645, we just need to take the remainder from this equation, which is 319.
So,
3644 mod 645 = 319 mod 645
Since 319 is less than 645, the remainder is simply 319.
Therefore,
3 644 mod 645 = 319 mod 645 = 3

A) 6 cartons of eggs will contain 4 more broken eggs than 4 cartons.
B) 8 cartons of eggs will contain 12 more broken eggs than 4 cartons.
C) 10 cartons of eggs will contain 8 more broken eggs than 4 cartons.
D) 12 cartons of eggs will contain 14 more broken eggs than 4 cartons.

Answers

10 cartons of eggs will contain 8 more broken eggs than 4 cartons if a grocery store worker is checking for broken egg cartons. Each carton of eggs contains 12 eggs. He checks 4 cartons and finds 8 broken eggs.

Assuming that the proportion of broken eggs in the sampled cartons is representative of the entire batch of cartons, the worker can use this information to predict the number of broken eggs in the rest of the cartons.

The worker checked 4 cartons of eggs, each with 12 eggs, for a total of 4 x 12 = 48 eggs. Out of these 48 eggs, 8 were found to be broken.

To estimate the number of broken eggs in the rest of the cartons, the worker can use proportionality. The proportion of broken eggs in the sample is 8/48 = 1/6. Therefore, the worker can predict that out of the marginal cost remaining cartons of eggs, 1/6 of the eggs will be broken.

The closest option is C, which predicts that there will be 16 broken eggs in 10 cartons, which is 8 more broken eggs than in the 4 cartons the worker checked. This implies an average of 2 broken eggs per carton, which is consistent with the prediction of 2x broken eggs in the remaining cartons. Therefore, option C is the best answer.

Kira's backyard has a patio and a garden. Find the area of the garden. (Sides meet at right angles.)

Answers

Answer:

  18 square yards

Step-by-step explanation:

You want the area of a garden that fills a back yard that is 4 yd by 6 yd except for a patio that is 3 yd by 2 yd.

Yard area

The area of the backyard is ...

  A = LW = (6 yd)(4 yd) = 24 yd²

Patio area

The area of the patio is ...

  A = LW = (3 yd)(2 yd) = 6 yd²

Garden area

The garden area is the area of the backyard that is not taken up by the patio:

  24 yd² -6 yd² = 18 yd²

The garden covers 18 square yards.

__

Additional comment

You can compute this many ways. You can divide the garden area into rectangles or trapezoids, or you can recognize that the garden is 3/4 of the area of the back yard.

(You get two trapezoids by cutting the garden along a line between the upper left corner of the yard and the upper left corner of the patio.)

Answers

The probability value for P(B) is obtained to be, Option (c) : 0.83.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

We can use the formula: P(A È B) = P(A) + P(B) - P(A Ç B) to find P(B).

Rearranging the terms, we get -

P(B) = P(A È B) - P(A) + P(A Ç B)

Substituting the given values, we get -

P(B) = 0.72 - 0.55 + 0.66

P(B) = 0.83

The probability of an event A occurring is denoted by P(A) and is a number between 0 and 1, inclusive.

If A and B are two events, then P(A È B) denotes the probability that at least one of A or B occurs.

P(A Ç B) denotes the probability that both A and B occur simultaneously.

The formula used to find P(B) in terms of P(A), P(A È B), and P(A Ç B) is known as the addition rule of probability.

Therefore, the answer is 0.83.

Sam has a pool deck that is shaped like a triangle with a base of 15 feet and a height of 9 feet. He plans to build a 4:5 scaled version of the deck next to his horse's water trough.
Part A: What are the dimensions of the new deck, in feet? Show every step of your work.
Part B: What is the area of the original deck and the new deck, in square feet? Show every step of your work.
Part C: Compare the ratio of the areas to the scale factor. Show every step of your work.

Answers

Part A:

The new deck will be a 4:5 scaled version of the original deck. This means that every dimension of the new deck will be 4/5 times the corresponding dimension of the original deck.

The original deck has a base of 15 feet and a height of 9 feet.

The new deck will have a base of (4/5) * 15 = 12 feet and a height of (4/5) * 9 = 7.2 feet.

Therefore, the dimensions of the new deck are 12 feet for the base and 7.2 feet for the height.

Part B:

To find the area of the original deck, we use the formula for the area of a triangle:

Area = (1/2) * base * height = (1/2) * 15 * 9 = 67.5 square feet.

To find the area of the new deck, we use the same formula with the new dimensions:

Area = (1/2) * 12 * 7.2 = 43.2 square feet.

Therefore, the area of the original deck is 67.5 square feet, and the area of the new deck is 43.2 square feet.

Part C:

The ratio of the areas is:

Area of new deck / Area of original deck = 43.2 / 67.5

Simplifying this fraction, we get:

Area of new deck / Area of original deck = 8 / 15

The scale factor is 4/5, which simplifies to 8/10 or 4/5.

Comparing the ratio of the areas to the scale factor, we see that:

Area ratio / Scale factor = (8/15) / (4/5) = (8/15) * (5/4) = 1

Therefore, the ratio of the areas is equal to the scale factor. This makes sense since the area of a triangle is proportional to the square of its dimensions. In this case, the scale factor is applied to both the base and the height, so the area ratio is equal to the scale factor squared, which is 16/25.

Answer:

Step-by-step explanation:

Part A: To find the dimensions of the new deck, we need to scale the base and height of the original deck by a factor of 4:5.

Scaling factor = 4/5

New base = 15 * (4/5) = 12 feet

New height = 9 * (4/5) = 7.2 feet

Therefore, the dimensions of the new deck are 12 feet for the base and 7.2 feet for the height.

Part B: The area of the original deck can be found by using the formula for the area of a triangle:

Area = (1/2) * base * height = (1/2) * 15 * 9 = 67.5 square feet.

The area of the new deck can also be found using the same formula:

Area = (1/2) * base * height = (1/2) * 12 * 7.2 = 43.2 square feet.

Part C: The ratio of the areas of the two decks can be found by dividing the area of the new deck by the area of the original deck:

Ratio of areas = (43.2 / 67.5) ≈ 0.64

The scale factor is 4:5 or 0.8.

Comparing the ratio of areas to the scale factor:

Ratio of areas / scale factor = (0.64 / 0.8) = 0.8

The ratio of the areas divided by the scale factor is equal to 0.8, which makes sense since the scale factor is the factor by which the dimensions were scaled up, and the ratio of areas tells us how much the area was scaled up.

Now, we need to find the tangential and normal components of the acceleration vector.

Tangential component (at) is the projection of the acceleration vector onto the velocity vector:
[tex]at = (a(t) • v(t)) / ||v(t)||^2 * v(t)[/tex]Dot product[tex]a(t) • v(t) = (0*1) + (2*2t) + (0*5) = 4t[/tex]Magnitude of v(t) squared = (1^2 + (2t)^2 + 5^2) = 1 + 4t^2 + 25

consider the function f(x) = 2 −e1−x. approximate f(1.01) using a linear approximation.

Answers

The linear approximation of f(1.01) is approximately 1.01.

To approximate f(1.01) using a linear approximation, we need to find the equation of the tangent line to the graph of f(x) at x = 1. We can do this by finding the slope of the tangent line and using the point-slope form of a linear equation.

First, we find the derivative of f(x):

f'(x) = e(1-x)

Then, we evaluate f'(1) to find the slope of the tangent line at x = 1:

f'(1) = e(1-1) = e0 = 1

So the slope of the tangent line is 1.

Next, we find the value of f(1):

f(1) = 2 - e(1-1) = 2 - e0 = 2 - 1 = 1

So the point on the graph of f(x) that corresponds to x = 1 is (1, 1).

Using the point-slope form of a linear equation, we can write the equation of the tangent line as:

y - 1 = 1(x - 1)

Simplifying, we get:

y = x

Now, we can use this equation to approximate f(1.01):

The derivative of y√(1/(t(8t+1))) is (dy/dt √(1/(t(8t+1))) - y * (4t√t+1 + √(8t+1))/(2t√(t(8t+1)))).

How to determined the derivative of y√(1/(t(8t+1))) by logarithmic differentiation?

To use logarithmic differentiation to find the derivative of y√(1/(t(8t+1))), we can follow these steps:

Take the natural logarithm of both sides of the equation y√(1/(t(8t+1))):

ln(y√(1/(t(8t+1)))) = ln(y) + 1/2 ln(1/(t(8t+1)))

Differentiate both sides of the equation with respect to t:

d/dt ln(y√(1/(t(8t+1)))) = d/dt [ln(y) + 1/2 ln(1/(t(8t+1)))]

Simplify the right-hand side of the equation using the rules of logarithms:d/dt ln(y√(1/(t(8t+1)))) = d/dt [ln(y) - ln(t) - 1/2 ln(8t+1)]d/dt ln(y√(1/(t(8t+1)))) = d/dt [ln(y) - ln(t) - 1/2 ln(8t+1)¹/²]d/dt ln(y√(1/(t(8t+1)))) = d/dt ln(y/(t√(8t+1)))

Apply the chain rule and simplify the expression on the right-hand side of the equation:d/dt ln(y√(1/(t(8t+1)))) = 1/(y/(t√(8t+1))) * (dy/dt √(1/(t(8t+1))) - y * (1/2 * 1/(t(8t+1))¹/² * 8 + 1/(2[tex](8t+1)^{0.5}[/tex])))d/dt ln(y√(1/(t(8t+1)))) = (dy/dt √(1/(t(8t+1))) - y * (4t/(2(8t+1))¹/² + 1/(2(8t+1))¹/²)) / (t√(8t+1) * y/t)Substitute the original expression for y:d/dt ln(y√(1/(t(8t+1)))) = (dy/dt √(1/(t(8t+1))) - y * (4t/(2(8t+1))¹/² + 1/(2(8t+1))¹/²)) / (t√(8t+1) * √(1/(t(8t+1))))d/dt ln(y√(1/(t(8t+1)))) = (dy/dt √(1/(t(8t+1))) - y * (4t√t+1 + √(8t+1))/(2t(8t+1))) / (√(t(8t+1)))Simplify the expression on the right-hand side of the equation as much as possible:

d/dt ln(y√(1/(t(8t+1)))) = (dy/dt √(1/(t(8t+1))) - y * (4t√t+1 + √(8t+1))/(2t√(t(8t+1))))

So, the final expression y√(1/(t(8t+1))) is

Answers

Since the limit of the sequence is 0, we can say that the sequence is bounded between 0 and some positive number (since all terms in the sequence are positive). Therefore, the answer is (A) bounded.

To determine whether the sequence is increasing, decreasing, or not monotonic, we need to look at how the terms in the sequence change as n increases.

We can rewrite the sequence as:

an = 1/(5n + 4)

As n increases, the denominator 5n + 4 also increases, which means that the fraction 1/(5n + 4) decreases. Therefore, the terms in the sequence decrease as n increases.

So the answer is (B) decreasing.

To determine whether the sequence is bounded, we need to consider the limit of the sequence as n approaches infinity.

Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel.

Answers

The median of complaints received per week is 2.

To find the median of complaints received per week, we need to arrange the probabilities in ascending order and then find the probability at the middle position.

Arranging the probabilities in ascending order, we get:

Number of complaints 0 1 2 3 4 5
Probability 0.05 0.07 0.09 0.18 0.26 0.35

The median position is (n+1)/2, where n is the total number of probabilities. In this case, n=6, so the median position is (6+1)/2=3.5.

The probability at position 3 is 0.09 and the probability at position 4 is 0.18. Therefore, the median probability is the average of these two probabilities, which is (0.09+0.18)/2=0.135.

To find the median number of complaints, we need to find the number of complaints that corresponds to the median probability. Starting from the first probability, we add up the probabilities until we reach a total of at least 0.135.

0.05 + 0.07 + 0.09 = 0.21

The median of complaints received per week is 2.

To find the median of complaints received per week, we need to arrange the probabilities in ascending order and then find the probability at the middle position.

Arranging the probabilities in ascending order, we get:

Number of complaints 0 1 2 3 4 5
Probability 0.05 0.07 0.09 0.18 0.26 0.35

The median position is (n+1)/2, where n is the total number of probabilities. In this case, n=6, so the median position is (6+1)/2=3.5.

The probability at position 3 is 0.09 and the probability at position 4 is 0.18. Therefore, the median probability is the average of these two probabilities, which is (0.09+0.18)/2=0.135.

To find the median number of complaints, we need to find the number of complaints that corresponds to the median probability. Starting from the first probability, we add up the probabilities until we reach a total of at least 0.135.

0.05 + 0.07 + 0.09 = 0.21

Therefore, the median number of complaints is 2.
So, the answer is 2 (rounded to the nearest integer).

P(not B+) = (the answer has to be in a fraction form , #/# don't simplify the fraction)

Answers

The probability of not selecting a person with blood type B+ is 90/100.



a) To find the probability of selecting a person with blood type A+ or A- (P(A+ or A-)), first count the number of people with each blood type, then divide the sum of those counts by the total number of people (100).

Number of people with blood type A+ = 34
Number of people with blood type A- = 6

P(A+ or A-) = (34 + 6) / 100 = 40/100

So, the probability of selecting a person with blood type A+ or A- is 40/100.

b) To find the probability of not selecting a person with blood type B+ (P(not B+)), first count the number of people without blood type B+ and then divide that count by the total number of people (100).

Number of people with blood type B+ = 10
Number of people without blood type B+ = 100 - 10 = 90

P(not B+) = 90 / 100 = 90/100

So, the probability of not selecting a person with blood type B+ is 90/100.

Let P be the transition probability matrix of a Markov chain. Argue that if for some positive integer r, P^r has all positive entries, then so does P^n, for all integers n greaterthanorequalto r.

Answers

If [tex]P^r[/tex] has all positive entries for some positive integer r, then [tex]P^n[/tex] will also have all positive entries for all integers n greater than or equal to r, due to the irreducibility of the Markov chain and the properties of matrix multiplication.

Given a transition probability matrix P of a Markov chain, if [tex]P^r[/tex] has all positive entries for some positive integer r, then [tex]P^n[/tex] also has all positive entries for all integers n greater than or equal to r.

Here's the explanation:
Let P be the transition probability matrix of a Markov chain, and let [tex]P^r[/tex] have all positive entries for some positive integer r. We want to show that [tex]P^n[/tex] has all positive entries for all integers n greater than or equal to r.

1. Since [tex]P^r[/tex] has all positive entries, the Markov chain is irreducible (meaning that there is a non-zero probability of transitioning between any two states in a finite number of steps).

2. Because the Markov chain is irreducible, there exists a positive integer k such that [tex]P^k[/tex] has all positive entries for all k greater than or equal to r.

3. Let n be an integer greater than or equal to r. We can express n as a multiple of k and some non-negative integer m, i.e., n = mk.

4. Then, [tex]P^n[/tex] = [tex]P^{mk[/tex] = [tex](P^k)^m[/tex]. Since [tex]P^k[/tex] has all positive entries, [tex](P^k)^m[/tex] also has all positive entries as the product of positive entries is always positive.

5. Therefore, [tex]P^n[/tex] has all positive entries for all integers n greater than or equal to r.

The Laplace transform of [tex]e^{(-4t)}sin(4t)[/tex] is 4/((s+4)² + 16).

In mathematics, the Laplace transform is an integral transform that converts a function of a real variable to a function of a complex variable s. The transform has many applications in science and engineering because it is a tool for solving differential equations.

To find the Laplace transform, denoted as ℒ{[tex]e^{(-4t)}sin(4t)[/tex]}, we'll use the following formula:

ℒ{[tex]e^{(-at)}f(t)[/tex]} = F(s+a)
where ℒ{f(t)} = F(s) is the Laplace transform of the function f(t), and "a" is the constant term in [tex]e^{(-at)}[/tex].

In this case, f(t) = sin(4t) and a = 4.

First, let's find the Laplace transform of f(t) = sin(4t), which is given by:
F(s) = ℒ{sin(4t)} = 4/(s² + 16)

Now, apply the formula for ℒ{[tex]e^{(-4t)}f(t)[/tex]}:

ℒ{[tex]e^{(-4t)}sin(4t)[/tex]} = F(s+4)

Substitute s+4 in the expression for F(s):

ℒ{[tex]e^{(-4t)}sin(4t)[/tex]} = 4/((s+4)² + 16)

Answers

a) Poppy's petrol was better value for money as it cost less per liter. b) 20 liters of petrol from the cheaper petrol station (Poppy's petrol station) would cost £26.00.

How to determine if Jacob's petrol or Poppy's petrol better value for money

a) To determine which petrol was better value for money, we need to calculate the price per liter for each petrol station:

Jacob's petrol: £18.90 / 14 litres = £1.35 per litre

Poppy's petrol: £22.10 / 17 litres = £1.30 per litre

Therefore, Poppy's petrol was better value for money as it cost less per litre.

b) To calculate the cost of 20 litres of petrol from the cheaper petrol station, we need to determine which petrol station was cheaper:

Jacob's petrol: £1.35 per litre x 20 litres = £27.00

Poppy's petrol: £1.30 per litre x 20 litres = £26.00

Therefore, 20 litres of petrol from the cheaper petrol station (Poppy's petrol station) would cost £26.00.

In 2010, Joe bought 200 shares in the Nikon Corp for $22.07 per share. In 2016 he sold the shares for $15.11 each.
a. What was Joe's capital loss?
b. Express Joe's capital loss as a percent, rounded to the nearest percent.

Answers

Joe's capital loss is $1,392.

Rounding to the nearest percent, we get that Joe's capital loss was 32%.

What is  capital loss?

Capital loss is the difference between the purchase price and the selling price of an asset when the selling price is lower than the purchase price. It represents the loss incurred by the investor or trader due to the decrease in the value of the asset. Capital loss can be realized or unrealized.

a. Joe's capital loss is the difference between the selling price and the purchase price of the shares.

Purchase price = 200 shares * $22.07 per share = $4,414

Selling price = 200 shares * $15.11 per share = $3,022

Capital loss = Purchase price - Selling price

Capital loss = $4,414 - $3,022

Capital loss = $1,392

Therefore, Joe's capital loss is $1,392.

b. To express Joe's capital loss as a percent, we need to divide the capital loss by the purchase price and then multiply by 100.

Capital loss percent = (Capital loss / Purchase price) * 100

Capital loss percent = ($1,392 / $4,414) * 100

Capital loss percent = 31.51%

Rounding to the nearest percent, we get that Joe's capital loss was 32%.

Answer:

y = -x - 2

Step-by-step explanation:

Pre-Solving

We are given that a line has a slope (m) of -1 and passes through (-19,17).

We want to write the equation of this line in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name

Solving

As we are already given the slope of the line, we can plug it into the equation.

Replace m with -1.

y = -1x + b

This can be rewritten to:

y = -x + b

Now, we need to find b.

As the equation passes through (-19,17), we can use its values to help solve for b.

Substitute -19 as x and 17 as y.

17 = -(-19) + b

17 = 19 + b

Subtract 19 from both sides.

-2 = b

Substitute -2 as b into the equation.

y = -x - 2
