Answer 1

To solve this problem, we will use the conditional probability definition: Given events A,B such that P(B)>0 we have that

[tex]P(A|B)=\frac{P(\text{A}\cap B)}{P(B)}[/tex]

Where P(A|B) means the probability of A given B occurred. This also leads to the following

[tex]P(A|B)\cdot P(B)=P(A\cap B)[/tex]

Now, let us define two events. Let M1 be the event that we select a male first and let F2 be the event that we select a female second. We want to calculate the following probabilty

[tex]P(M_1\cap F_2)_{}[/tex]

Using the definition of conditional probability, this is the same as

[tex]P(M_1\cap F_2)=P(F_2|M_1)\cdot P(M_1)[/tex]

Now, we will calculate P(M1). At the beginning, when we have not picked anyone yet, we have 37 people (21 Female and 16 Male). So the probability of picking a male first is simply

[tex]P(M_1)=\frac{16}{37}[/tex]

Now, we will calculate the second probability. Since we already picked one male, we have now 36 people (21 female and 15 male). Then the probability of picking a female is

[tex]P(F_2|M_1)=\frac{21}{36}[/tex]

So,

[tex]P(M_1\cap F_2)=\frac{16}{37}\cdot\frac{21}{36}=\frac{28}{111}=0.252[/tex]

The absolute functions when matched to the respective vertex is as follows;

(-1, -3/7) → f(x) = (1/2)|x + 1| - (3/7)

(5, 2/3) → f(x) = (-3/5)|x - 5| + (2/3)

(0, -4/5) → f(x) = (1/2)|x| - (4/5)

(2/5, 5/3) → f(x) = (-3/2)|x - (2/5)| + (5/3)

What is the absolute value function of the Vertices?

We can solve all of them by writing the equations in a general form;

f(x) = a|x + b| + c

This is a function transformation of f(x) = |x|

where:

a = Factor of vertical stretch

b = Horizontal shift (- shifts right, + shifts left)

c = Vertical shift (+ shifts right, - shifts left)

The original function has its vertex in (0, 0)  so the horizontal shift will be the new x coordinate in the new vertex and the vertical shift will be the new y in the new vertex like this:

f(x) = (1/2)|x + 1| - (3/7)

b = 1 horizontal shift of -1

c = -3/7 vertical shift of -3/7

Thus, (-1, -3/7)

f(x) = (-3/5)|x - 5| + (2/3)

b = -5 horizontal shift of 5

c = 2/3 vertical shift of 2/3

Thus, (5, 2/3)

f(x) = (1/2)|x| - (4/5)

b = 0 horizontal shift of 0

c = -4/5 vertical shift of -4/5

Thus, (0, -4/5)

f(x) = (-3/2)|x - (2/5)| + (5/3)

b = -2/5 horizontal shift of 2/5

c = 5/3 vertical shift of 5/3

Thus, (2/5, 5/3)

The proper subset relationship of the given set A, B and C are in option;

A B is the set notation used to symbolize a set A as a subset of a larger set B.A proper subset would be any subset of a set that is not the set itself. Every set, we know, is a subset of itself, but it is not a proper subset of it's own.The correct subset symbol is ⊂ . In other words, if A is a proper subset of B, after which:A ⊂ B andA ≠ B

For the given question;

The set are given as;

A = { x | x = 2n + 1, n ∈ R }

This, can be written as for the real number say, n = 0, 1, 2, 3....

A = {1, 5, 7, 9 , 11 ..}

B = { x | x = 4n + 1, n ∈ R }

This, can be written as for the real number say, n = 0, 1, 2, 3....

B = {1, 5, 9, ....}

C = { x | x = 8n + 1, n ∈ R }

How to use rigid transformations to modify functions

In this problem we must use rigid transformations to change the definition of a series of functions. Rigid transformations are transformations applied on functions such that its form is not altered. There are the following transformations, which are used in the five cases:

Horizontal translation

g(x) = f(x - k), translation is to the right for k > 0.

Vertical translation

g(x) = f(x) + k, translation is upward for k > 0

Reflection over the x-axis

g(x) = - f(x)

Reflection over the y-axis

g(x) = f(- x)

Now we proceed to present the image of each function after using a sequence of rigid transformations:

f(x) = |x|; g(x) = |x - 3| + 2f(x) = |x|; g(x) = |x + 4| - 2f(x) = |x|; g(x) = - |x| - 3f(x) = x²; g(x) = (x - 3)² - 2f(x) = √x; g(x) = √(- x) + 5

We can define the translation of building from location C to location E by the following rule -

(x, y) → (x - 4 , y + 6)

What is translation of graph?

A translation is a movement of the graph either horizontally (parallel to the x -axis) or vertically (parallel to the y -axis) without changing its orientation.

Given is a Building C translated to Building E.

In order to translate the building from location C to location E, we will first shift the building near the x - axis vertically upwards. For this we will shift the y coordinate by -

- 7 + y[s] = - 1

y[s] = -1 + 7

y[s] = 6

So the y - coordinate of the translated graph will be -

(y + 6)

Now, we will shift the x coordinate -

1 + x[s] = -3

x[s] = -3 - 1

x[s] = -4

So the x - coordinate of the translated graph will be -

(x - 4)

Therefore, we can define the translation by the following rule -

(x, y) → (x - 4 , y + 6)

Answers

A randomly chosen beagle has a 0.86508  probability of weighing more than 21.8 pounds.

How can probability be explained?

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be represented as percentage with values between 0 and 1.

What does the term "z-score" mean?

The relationship between a value and the mean of a group of values is quantified by a Z-score.

Adult male beagle weight is normally distributed, with a mean of 25.0 pounds and a standard deviation of 2.9 pounds.

Given values are:

Mean(μ) = 25 pounds

Standard deviation(σ) = 2.9 pounds

Sample mean(x') = 21.8

We need to calculate z-score:

z = (x' - μ)/σ

z = (21.8 - 25)/2.9

z = 1.25

P-value from Z-Table:

P(x>21.8) = 1 - P(x<21.8) = 0.86508

One example of real-world situation that uses logarithms is for amount of substance that are decaying over time.

Logarithms and amount of substances

In which:

P(0) is the initial amount.k is the exponential decay rate, as a decimal.

The simplest example of the use of logarithms is to find the half-life of the substance, that is, the year t for which P(t) = 0.5P(0).

Then:

[tex]0.5P(0) = P(0)e^{-kt}[/tex]

[tex]e^{-kt} = 0.5[/tex]

The natural logarithm is used to find the half life, as it is the inverse of the exponential.

BA = BA + BA + BA =3

P = P + P =2

Hence,

5. If the standard error of the sampling distribution of the sample proportion is 0.0337 for samples of size 200, then the population proportion must be either:

Answers

The population proportion when the standard error of the sampling distribution of the sample proportion is 0.0337 for samples of size 200 must be D. 0.35 or 0.65.

How to illustrate the information?

Based on the information, it should be noted that the formula for the standard error for the population will be:

✓p(1 - p)/n

where

p = population proportion

n = sample size

Therefore, this will be illustrated as:

✓p(1 - p)/n = 0.0337

Remove the square root

p( 1 - p)/200 = 0.00113569

Cross multiply

p(1 - p) = 0.227138

p - p² = 0.227138

Equate to 0

p² - p + 0.227138 = 0

Using almighty formula, P1 = 0.6512 and P2 = 0.3488

Therefore, the correct option is D.

Use what you know about domain to select all of the following functions that could be the one graphed.

Answers

Using transformations, more specifically a translation, the functions that could represent the one graphed are given as follows:

y = sqrt(x) - 3.y = sqrt(x) - 1.

Why is the transformation in this problem a translation?

We first consider the parent square root function, defined as follows:

y = sqrt(x).

It's domain, that is, the possible values that the input x can assume, is given as follows:

x ≥ 0.

The graphed function has the same domain as the parent square root function, just with a different range, as it was shifted down, assuming the following format:

y = sqrt(x) - a.

In a translation, the function keeps the same format and orientation, just changing it's position, which is what happened in this case.

The possible translations are:

1 unit down, hence a = 1 and y = sqrt(x) - 1.3 units down, hence a = 3 and y = sqrt(x) - 3.

The other functions would change the domain of the function, hence they are not possible.
