A rectangle has a perimeter of 45.6 cm and a base of 12 cm. Find the height.​

Answers

Answer 1

Answer:

10.8

Step-by-step explanation:

12+12=24

45.6-24=21.6 (both sides)

21.6/2=10.8 (one side)

Answer 2

The height of a rectangle with a perimeter of 45.6 cm and a base of 12 cm will be 10.8 centimeters.

In the question, we are given the perimeter of a rectangle and the measurement of the base.

We know that the formula of the perimeter of a rectangle is twice the sum of its base (b) and height (l):

Perimeter of a Rectangle = 2 ( l + b )

We will now put the values given in the question in the above formula:

45.6 = 2( l + 12 )

45.6 = 2l + 24

2l = 45.6 - 24 (we transpose 24 to the left side of the equation, and thus, the sign changes)

2l = 21.6

l = 21.6/2

l = 10.8

The juror pool for an upcoming trial contains 100,000 individuals in the population who may be called for jury duty. The proportion of the available jurors on the population list who are Hispanic is 0.44. A jury of size 8 is selected at random from the population list of available jurors. Let X = the number of Hispanics selected to be jurors for this jury.
Find the probability that no Hispanic is selected. (Round to four decimal places as needed.)

Answers

The probability of no Hispanic being selected is 0.0496 (rounded to four decimal places).

Probability is a branch of mathematics that deals with the study of random events or experiments, and the likelihood or chance of their occurrence. It is a measure of the degree of certainty or uncertainty of an event, expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event is certain to occur.

We can model the number of Hispanics selected as jurors with a binomial distribution, where n=8 is the number of trials (selecting jurors), and [tex]$p=0.44$[/tex] is the probability of success (selecting a Hispanic juror).

The probability of selecting no Hispanic jurors is given by:

[tex]$P(X=0) = \binom{8}{0}(0.44)^0(1-0.44)^8 \approx 0.0496$[/tex]

The graph of the function g(x) = -x is shown on the grid below. which of the following is the graph of y = g(x)-6?​

Answers

Note that the graph of y=g(x) -6 where g(x) = -x is represented by the funciton y = -x-6. See graph attached.

What is the rationale for the above?

The graph of the function g(x) = -x is a straight line passing through the origin with a slope of -1.

To find the graph of y = g(x) - 6, we need to shift the graph of g(x) downward by 6 units.

This can be done by subtracting 6 from the y-coordinate of every point on the graph of g(x).

Therefore, the graph of y = g(x) - 6 is obtained by shifting the graph of g(x) downward by 6 units. The resulting graph is a straight line passing through the point (0, -6) with a slope of -1.

Answers

The slope of the line is - 1.

What is the slope of a line.

A line in the cartesian plane, is a particular set of points. Each point in the plane has a pair of cartesian coordinates, one each corresponding to the x and y coordinate respectively. The slope of the line segment joining two points is the change in the y-coordinate, divided by the change in the x-coordinate, as we move from the first point to the second point. The line as a geometric figure is characterized by the property that, the slope of the line segment joining any two distinct points on the line is the same. This slope is then denoted to be the slope of the line.

How do you find the slope of a line.

To calculate the slope of a line, we need two points, on the line. let P,Q be two points on the line. Let [tex](x_p,y_p), (x_q,y_q)[/tex] be the coordinates of the two points. then the slope of the line segment [tex]{PQ}[/tex] is the ratio [tex]\frac{y_p-y_q}{x_p-x_q}[/tex] . This is also equal to the slope of the line containing the points P, Q

In our question the line passes through the points, (1,2) and (-1,4). These points are marked on the line with highlighted dots. So the slope of the line  in the picture is (4-2)/(-1-1) = 2/-2 = -1

Convert the integral ∫∫ r √4 −x2−y2da where r = {(x, y) : x2 y2≤ 4, x ≥ 0} to polar coordinates, and then evaluate.

Answers

The integral ∫∫ r √4 −x2−y2da where r = {(x, y) : x2 y2≤ 4, x ≥ 0} conversion to polar coordinates the value of the integral is (4/3)π.

To convert the integral to polar coordinates, we need to express the limits of integration in terms of the polar coordinates.

Recall that in polar coordinates, x = r cosθ and y = r sinθ, where r is the radial distance from the origin and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin to the point (x, y).

In this case, the region r is defined by [tex]x^2 + y^2[/tex] ≤ 4 and x ≥ 0. In polar coordinates, this corresponds to the region 0 ≤ r ≤ 2 and 0 ≤ θ ≤ π/2. To see why, note that x ≥ 0 implies 0 ≤ θ ≤ π/2, and [tex]x^2 + y^2 = r^2[/tex], so r ≤ √4 = 2.

So we have:

∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) ∫(r=0 to 2) r√(4-[tex]r^2[/tex]) dr dθ

To evaluate this integral, we can use the substitution u = 4 - [tex]r^2[/tex], du = -2r dr, which gives:

∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) ∫(u=4 to 0) -1/2 √u du dθ

Now we can evaluate the inner integral:

∫(u=4 to 0) -1/2 √u du = [-1/3 u^(3/2)](u=4 to 0) = (1/3)(8 - 0) = 8/3

Substituting this back into the original integral, we have:

∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) (8/3) dθ = (8/3) (π/2 - 0) = (4/3)π

Therefore, the value of the integral is (4/3)π.

Answers

The given statement is "You are more likely to make a Type II error with a t-test than with a comparable z-test." can either be true or false because it depends on the sample size and the underlying population distribution.




A t-test is used when the population standard deviation is unknown and is estimated from the sample data.

The t-distribution is used to account for the uncertainty in estimating the population standard deviation. As the sample size increases, the t-distribution approaches the z-distribution (or standard normal distribution).

A z-test is used when the population standard deviation is known or the sample size is large. It uses the standard normal distribution for hypothesis testing.

When the sample size is small and the underlying population distribution is non-normal, a t-test may have a higher chance of making a Type II error compared to a z-test.

However, when the sample size is large or the underlying population is normally distributed, the difference in the likelihood of making a Type II error between the two tests becomes negligible.

In summary, whether you are more likely to make a Type II error with a t-test than with a comparable z-test depends on the sample size and the underlying population distribution.

determine intervals in which solutions are sure to exist. (enter your answer using interval notation.) y(4) 7y''' 5y = t

Answers

The general solution for the non-homogeneous equation is y(t) = yh(t) + yp(t) = c1 + c2t + c3e^(-0.3726t) + c4e^(0.3726t) + (1/7)t - 1/49.

To determine intervals in which solutions are sure to exist for the differential equation y(4) + 7y''' + 5y = t, we need to look at the characteristic equation, which is r^4 + 7r^3 + 5r = 0. Factoring out an r, we get r(r^3 + 7r^2 + 5) = 0. This gives us two roots: r = 0 and r = -0.3726, approximately. For the homogeneous equation, the general solution is yh(t) = c1 + c2t + c3e^(-0.3726t) + c4e^(0.3726t).

To find particular solutions for the non-homogeneous equation, we need to consider the form of the forcing term t. Since it is a linear function, we can guess a particular solution of the form yp(t) = At + B. Substituting this into the equation, we get 7A - 1 = 0, which means A = 1/7. Then, substituting back in and solving for B, we get B = -1/49. So our particular solution is yp(t) = (1/7)t - 1/49.

Therefore, the general solution for the non-homogeneous equation is y(t) = yh(t) + yp(t) = c1 + c2t + c3e^(-0.3726t) + c4e^(0.3726t) + (1/7)t - 1/49. Since all of the terms in the general solution are continuous and differentiable on the entire real line, solutions are sure to exist for all values of t, and the interval notation for this would be (-∞, ∞).

suppose that the supply function for a good is p=4x^2 18x 7. if the equilibrium price is 259 per unit, what is the producer's surplus there?

Answers

The producer's surplus at the equilibrium price of 259 per unit is 882. Here, the supply function for a good is p = 4x^2 + 18x + 7, and the equilibrium price is 259 per unit, we need to find the producer's surplus.


Step 1: The equilibrium quantity (x) by setting the supply function equal to the equilibrium price:
259 = 4x^2 + 18x + 7
Step 2: Solve for x:
4x^2 + 18x + 7 - 259 = 0
4x^2 + 18x - 252 = 0
Using the quadratic formula or factoring, we find that x = 7 (the positive equilibrium quantity).
Step 3: Calculate the producer's surplus. The producer's surplus is the area between the supply curve and the equilibrium price, up to the equilibrium quantity:
Producer's Surplus = 0.5 * (base) * (height)
Base = equilibrium quantity = 7
Height = equilibrium price - supply price at x = 0 (the intercept of the supply curve)
Height = 259 - (4 * 0^2 + 18 * 0 + 7) = 259 - 7 = 252
Step 4: Plug in the values to calculate the producer's surplus:
Producer's Surplus = 0.5 * 7 * 252 = 882
So, the producer's surplus at the equilibrium price of 259 per unit is 882.

If a card is drawn from a "standard-deck" and then month of year is chosen, then the probability of selecting "face-card" and June month is 1/52.

The probability of getting a face-card from a standard-deck of 52 cards is 12/52, since there are 12 face cards (four jacks, four queens, and four kings) in the deck.

let a be a finite set. let s be the set of all subsets of a. then |s| = 2|a| . (the set s is called the power set of a

Answers

A finite set is a set that has a specific number of elements (as opposed to an infinite set, which has an infinite number of elements).

A subset is a set that contains some (or all) of the elements of another set. For example, if A = {1, 2, 3, 4}, then {1, 2} is a subset of A.

The power set of a set is the set of all subsets of that set. So, if A = {1, 2, 3}, then the power set of A is the set { {}, {1}, {2}, {3}, {1,2}, {1,3}, {2,3}, {1,2,3} }, which contains all possible combinations of the elements of A. Note that the power set always includes the empty set and the set itself.

Now, let's prove the statement |s| = 2|a|.

To do this, we need to show that the number of elements in s (the power set of a) is equal to 2 to the power of the number of elements in a.

First, let's think about how many subsets a finite set with n elements has.

For each element in the set, there are two choices: include it in a particular subset, or don't include it. So, for one element, there are 2 choices. For two elements, there are 2 x 2 = 4 choices. For three elements, there are 2 x 2 x 2 = 8 choices. In general, for a set with n elements, there are 2 x 2 x ... x 2 (n times) = 2^n choices.

Therefore, the power set of a set with n elements has 2^n elements.

So, in our case, if a is a finite set with |a| elements, then the power set of a (s) has 2^|a| elements.

Therefore, |s| = 2^|a|, which proves that |s| = 2|a|.

I hope that helps! Let me know if you have any other questions.
Hi! The given statement is true. If 'a' is a finite set, then 's' is the set of all subsets of 'a', also known as the power set of 'a'. The cardinality (or size) of the power set, denoted by |s|, is equal to 2 raised to the power of the size of the finite set 'a', i.e., |s| = 2^|a|.

y = 212e^3t-2 y=214e^3t-2

Answers

If the rate of change of y with respect to t is 3 times the value of the quantity 2 less than y, then the equation for y is y = 210e^(3t) + 2.

Explanation:

Let's work on this problem step by step:

Step 1: The problem states that the rate of change of y with respect to t is 3 times the value of the quantity 2 less than y. This can be represented as:

dy/dt = 3(y - 2)

Step 2: We are also given that y = 212 when t = 0. This will be used later to find the constant of integration.

Step 3: Now, we need to solve the differential equation. To do this, first, separate the variables:

dy/(y - 2) = 3 dt

Step 4: Integrate both sides with respect to their respective variables:

∫(1/(y - 2)) dy = ∫(3) dt

Step 5: This gives:

ln|y - 2| = 3t + C

Step 6: To find the constant of integration C, use the given condition that y = 212 when t = 0:

ln|212 - 2| = 3(0) + C
ln|210| = C

Step 7: Substitute C back into the equation:

ln|y - 2| = 3t + ln|210|

Step 8: To remove the natural logarithm, use the exponential function:

y - 2 = 210 * e^(3t)

Step 9: Add 2 to both sides of the equation to isolate y:

y = 210 * e^(3t) + 2

So, the equation for y is y = 210e^(3t) + 2.

Once you have this data, you can use statistical methods to calculate the upper confidence bound.
One common approach is to use the formula:
Upper Confidence Bound = Sample Mean + (Z-Score x Standard Error)
The Z-score corresponds to the desired level of confidence, such as 95% or 99%, and can be found in a standard normal distribution table.

The standard error is calculated using the sample size and sample standard deviation.
For example,

If you have a sample size of 50 blackbirds and a sample mean duration of 10 minutes with a sample standard deviation of 2 minutes, and you want a 95% confidence level, the Z-score would be 1.96.

The standard error would be 2 / sqrt(50) = 0.28.

Plugging these values into the formula, you would get:
Upper Confidence Bound = 10 + (1.96 x 0.28)

Upper Confidence Bound = 10.55
Therefore,

We can say with 95% confidence that the true average time that blackbirds spend on a single visit at the experimental location is less than or equal to 10.55 minutes.

how many different 2–card hands can be selected from a deck of 52 cards?

Answers

There are 1326 different 2-card hands that can be selected from a standard deck of 52 cards, determined by using the formula for combinations.

Let us assumes that each card is equally likely to be drawn and that the deck is well-shuffled. To determine the number of different 2-card hands that can be selected from a standard deck of 52 cards, we use the formula for combination. We want to choose 2 cards out of 52, so the formula is

C(52, 2) = 52! / (2! * (52-2)!) = 52 * 51 / 2 = 1326

Therefore, there are 1326 different 2-card hands that can be selected from a deck of 52 cards.

Write out the joint probability for the following sentence using the chain rule:
p(There, is, only, one, person, who, is, not, ordinary)
Write out the probability above using the second-order Markov assumption.

Answers

To write out the joint probability for the given sentence using the chain rule, we can express it as follows: p(There, is, only, one, person, who, is, not, ordinary) =



p(There) * p(is | There) * p(only | is, There) * p(one | only, is, There) *, p(person | one, only, is, There) * p(who | person, one, only, is, There) *,p(is | who, person, one, only, is, There) * p(not | is, who, person, one, only, is, There) *,p(ordinary | not, is, who, person, one, only, is, There).



This expression applies the chain rule to break down the joint probability of the sentence into the product of the conditional probabilities of each word given the preceding words in the sentence. To write out the probability using the second-order Markov assumption, we assume that the probability of each word only depends on the two preceding words. Therefore, we can express the probability as follows:



p(There, is, only, one, person, who, is, not, ordinary) = p(There) * p(is | There) * p(only | There, is) * p(one | is, only) *
p(person | only, one) * p(who | one, person) * p(is | person, who) *
p(not | who, is) * p(ordinary | is, not)
This expression only considers the two preceding words for each word in the sentence, which is the second-order Markov assumption.

Use PMI to prove that 22n+1 +7 is a multiple of 3 for n≥1.

Answers

Therefore, by PMI, we can conclude that 22n+1 +7 is a multiple of 3 for n≥1.

what is multiple  ?

In mathematics, a multiple is a product of an integer and any other integer. In other words, if a and b are integers, and there exists an integer c such that a = b x c, then a is a multiple of b, and we say that b divides a (or that b is a divisor or factor of a).

In the given question,

To prove that 22n+1 + 7 is a multiple of 3 for n≥1 using PMI, we will first establish the base case and then prove the induction step.

Base case:

When n=1, we have:

22n+1 + 7 = 22(1)+1 + 7 = 4+7 = 11

11 is not a multiple of 3. So the statement is not true for n=1.

Induction step:

Assuming that the statement is true for some integer k≥1, we will prove that it is also true for k+1.

So, we need to show that:

22(k+1)+1 + 7 is a multiple of 3

Expanding the expression, we have:

22(k+1)+1 + 7 = 2 x 22k+1 x 2 + 7

= 2 x 22k+2 + 7

We can write 2 as (3-1), and substitute it in the expression:

2 x 22k+2 + 7 = (3-1) x 22k+2 + 7

= 3 x 22k+2 - 22k+2 + 7

Notice that 22k+2 is a multiple of 3 because 22k+1 is even, and 22 is a multiple of 3. Therefore, we have:

3 x 22k+2 - 22k+2 + 7 = 3 x (22k+2) + (-22k+2 + 7)

= 3 x (22k+2) + (-22k+5)

Now, let's consider the expression (-22k+5). We can rewrite it as (-22k+3+2):

(-22k+5) = (-22k+3+2) = -3 x 2k+1 + 2 x 1

Since 2k+1 is odd, we can write it as 2j+1, where j is an integer. Substituting this value in the expression, we have:

-3 x 2k+1 + 2 x 1 = -3 x 2j+2 + 2

= -3 x (2j+1) + 2

= -3 x 2j+1 + (-3+2)

= -3 x 2j+1 - 1

So, we can rewrite the original expression as:

3 x (22k+2) + (-22k+5) = 3 x (22k+2) - 3 x 2j+1 - 1

= 3 x (22k+2 - 2j-1) - 1

Notice that 22k+2 - 2j-1 is an even number, and therefore, it can be written as 2m for some integer m. Substituting this value, we have:

3 x (22k+2 - 2j-1) - 1 = 3 x 2m - 1

= 3m + 3m + 3 - 1

= 3 x (2m+1) + 2

Since 2m+1 is an integer, we can conclude that 22(k+1)+1 + 7 is a multiple of 3.

Therefore, by PMI, we can conclude that 22n+1 +7 is a multiple of 3 for n≥1.

Exercise 6.10.2: n-ary relations, cont. Consider the following two relations below: • R = {(a, b, c): a, b, c are positive integers and a

Answers

1. R = {(a, b, c): a, b, c are positive integers and a < b < c} ; 2. S = {(x, y): x is a multiple of y}

For the first relation R, we can see that it is an n-ary relation with n = 3. The condition a < b < c ensures that the triplets (a, b, c) are in increasing order. For example, (1, 2, 3) is a valid element of R, but (3, 2, 1) is not.

For the second relation S, we can see that it is a binary relation with n = 2. The condition x is a multiple of y means that for every pair (x, y) in S, x must be divisible by y. For example, (12, 2) is a valid element of S, but (5, 3) is not.

what is the total width of an element, where the content is 100 pixels wide, the padding is 10 pixels thick, the border is 2 pixels thick, and the margin is 5 pixels thick?

Answers

134 pixels total width of an element, where the content is 100 pixels wide, the padding is 10 pixels thick, the border is 2 pixels thick, and the margin is 5 pixels thick.

The total width of the element would be 117 pixels. This is because you need to add the content width of 100 pixels, the left and right padding of 10 pixels each (which makes a total of 20 pixels), the left and right border of 2 pixels each (which makes a total of 4 pixels), and the left and right margin of 5 pixels each (which makes a total of 10 pixels). Adding all these values gives you a total width of 117 pixels.
The total width of an element with a content width of 100 pixels, padding of 10 pixels, border of 2 pixels, and margin of 5 pixels can be calculated as follows:

Total width = Content width + (Padding * 2) + (Border * 2) + (Margin * 2)

Total width = 100 pixels + (10 pixels * 2) + (2 pixels * 2) + (5 pixels * 2)

Total width = 100 pixels + 20 pixels + 4 pixels + 10 pixels

Total width = 134 pixels

So, the total width of the element is 134 pixels.
