Based on the density graph below, what is the probability of a value in the sample space being anywhere from 40 to 60? A. 75% B. 50% C. 25% D. 100%

Answer:

The number line is y = 2.

Step-by-step explanation:

We are given the points (-1,2) , (-5,2) and we have to find the number line that can be used find the distance between them.

The y coordinate of the two points is

same (equal to 2) , so the number line that can be used to find the distance between them is y = 2.

Distance between the points = |-5+1| = 4

Answer:

0.06

Step-by-step explanation:

0.006 x 10

When multiplying by 10, 100, 1000, 10000, etc, you move the decimal place to the right as many times as there are zeros in what you are multiplying it by. Because there is one zero in ten, we move the decimal place one to the right.

0.06

Answer:

the answer is D 46 cm

Step-by-step explanation:

first you need to find the missing side measurements cutting in two separate figures. if one side is 2 you know the other side is also 2 same with the 4 if the top is 4 the bottom is 4 too so now you have the measurements for the first figure now you finder the area applying the formula

A=bxh

A= 4*2=8

second figure you know that one part of the rectangle top is 5 and if you add the 4 of the first figure give you the measurement of the top

5+4=9 so if the top is 9 the bottom is also 9

finally to find the other side you know the side is 6 and since you know one part of the first figure is 2 you need to subtract 6-2=4

A=bxh

A=9*4=28

once you have both you can add it 28+8=46

Answer:

A

Answer:

f(4) = 19

Step-by-step explanation:

Plug in 4 for x in the given equation:

f(x) = 5x - 1

f(4) = 5(4) - 1

Simplify. Remember to follow the order of operations, PEMDAS. First multiply, then subtract:

f(4) = (5 * 4) - 1

f(4) = 20 - 1

f(4) = 19

f(4) = 19 is your answer.

Answer:

This represents 2.6803%

Step-by-step explanation:

We start by calculating the z-score

Mathematically;

z-score = (x - mean)/SD

here our x is 55

mean = 82

SD = 14

z-score = (55-82)/14

z-score = -1.93

So the probability that a test taker will be retested will be;

P( x < -1.93)

We use the standard normal distribution table for this

P( x < -1.93) = 0.026803

If we convert this to percentage, we have 2.6803%

Answer:

He should be paying $5 monthly.

Step-by-step explanation:

500*0.01=5, I think this was a question from flocabulary, next time, try to also add the answer choices.

The true statement is that the amount of money which Eddie would be charged for each monthly withdrawal is equal to $5.

A paycheck refers to a financial document issued to an employee by an employer, as payment for the work done over a specific period of time.

Since the interest on Eddie's monthly withdrawal is 1% (0.01), it simply means that the service charge would be calculated by multiplying his wages by the interest rate.

Service charge = 500 × 0.01

Service charge = $5.

Answer:

The approximate value of [tex]P(0.45<\bar X<0.50)[/tex] is 0.3686.

Step-by-step explanation:

The pdf of X is:

[tex]f(x) = 6x(1-x), 0 < x < 1[/tex]

Compute the mean as follows:

[tex]\mu=\int\limits^{1}_{0} {x\times 6x(1-x)} \, dx \\\\=\int\limits^{1}_{0} {6x^{2}-6x^{3}} \, dx\\\\=[\frac{6x^{3}}{3}]-[\frac{6x^{4}}{4}]|^{1}_{0}\\\\=2-\frac{3}{2}\\\\=0.50[/tex]

Compute the variance as follows:

[tex]\sigma^{2}=E(X^{2})-(\mu)^{2}[/tex]

[tex]E(X^{2})=\int\limits^{1}_{0} {x^{2}\times 6x(1-x)} \, dx \\\\=\int\limits^{1}_{0} {6x^{3}-6x^{4}} \, dx\\\\=[\frac{6x^{4}}{4}]-[\frac{6x^{5}}{5}]|^{1}_{0}\\\\=\frac{3}{2}-\frac{6}{5}\\\\=0.30[/tex]

[tex]\sigma^{2}=E(X^{2})-(\mu)^{2}\\\\\sigma=\sqrt{E(X^{2})-(\mu)^{2}}\\\\=\sqrt{0.30-(0.50)^{2}}\\\\=0.2236[/tex]

According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.  

Then, the mean of the sample means is given by,

[tex]\mu_{\bar x}=\mu[/tex]

And the standard deviation of the sample means is given by,

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]

The sample selected is of size n = 64 > 30. Thus a central limit theorem can be applied to approximate the sampling distribution of sample mean.

Compute the value of [tex]P(0.45<\bar X<0.50)[/tex] as follows:

[tex]P(0.45<\bar X<0.50)=P(\frac{0.45-0.50}{0.2236/\sqrt{64}}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{0.50-0.50}{0.2236/\sqrt{64}})[/tex]

                                [tex]=P(-1.12<Z<0)\\\\=P(Z<0)-P(Z<-1.12)\\\\=0.50-0.13136\\\\=0.36864\\\\\approx 0.3686[/tex]

Thus, the approximate value of [tex]P(0.45<\bar X<0.50)[/tex] is 0.3686.

Answer: the answer is choice b

Step-by-step explanation:

The data in the first table represents a linear function that has a slope of zero

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Slope (m) = change in y / change in x

From the first table, using the point (-5, 5) and (-1, 5), hence:

Slope = (5 - 5)/(-1 - (-5)) = 0

The data in the first table represents a linear function that has a slope of zero

Answer:

[tex]D_u f(0,\pi/6)=\frac{4\sqrt{3}-3}{5}[/tex]

Step-by-step explanation:

We are given that

[tex]f(x,y)=2cos(y)e^{x}[/tex]

Point=([tex]0,\pi/6[/tex])

Vector v=<-8,6>

We have to find the directional derivative of the function.

[tex]f_x(x,y)=2cos(y)e^{x}[/tex]

[tex]f_x(0,\pi/6)=\sqrt{3}[/tex]

[tex]f_y(x,y)=-2sin(y)e^{x}[/tex]

[tex]f_y(0,\pi/6)=-1[/tex]

[tex]|v|=\sqrt{(-8)^2+6^2}=\sqrt{100}=10[/tex]

[tex]\hat{u}=\frac{v}{|v|}=\frac{-8i+6j}{10}=\frac{1}{10}(-8i+6j)[/tex]

[tex]\nabla f(0,\pi/6)=<f_x(0,\pi/6),f_y(0,\pi/6)>=<\sqrt{3},-1>[/tex]

Now, the directional derivative in the direction of v at point (0,[tex]\pi/6[/tex]) is given by

[tex]D_u f(0,\pi/6)=\nabla f(0,\pi/6)\cdot \hat{u}[/tex]

By using the formula

[tex]D_u f(x,y)=\nabla f(x,y)\cdot \hat{u}[/tex]

[tex]D_u f(0,\pi/6)=<\sqrt{3},-1>\cdot <-\frac{8}{10},\frac{6}{10}>[/tex]

[tex]D_u f(0,\pi/6)=-\frac{4\sqrt{3}}{5}-\frac{3}{5}=-\frac{1}{5}(4\sqrt{3}+3)[/tex]
