When Victoria goes bowling, her scores are normally distributed with a mean of 130 and a standard deviation of 11. What is the probability that the next game Victoria bowls, her score will be between 123 and 130, to the nearest thousandth?

Answers

Answer:

0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 130 and a standard deviation of 11.

This means that [tex]\mu = 130, \sigma = 11[/tex]

What is the probability that the next game Victoria bowls, her score will be between 123 and 130?

This is the p-value of Z when X = 130 subtracted by the p-value of Z when X = 123. So

X = 130

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{130 - 130}{11}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a p-value of 0.5

X = 123

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{123 - 130}{11}[/tex]

[tex]Z = -0.64[/tex]

[tex]Z = -0.64[/tex] has a p-value of 0.2611

0.5 - 0.261 = 0.239

0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130

what is the area of a square with its side length of s cm

Answers

Answer:

Step-by-step explanation:

Answer:

The area is s².

Step-by-step explanation:

The area of a square is the length times the width. Because it's a square, the length and width are the same, so instead of multiplying the length and width, we can take the length of one side and square it. You said the length is "s", which I assume is a variable, so the area will equal s ⋅ s, or s².

The slope of the line below is -2. Write the equation of the line in point-slope
form, using the coordinates of the labeled point. Do not use parenthesis on
the y side.

Answers

Answer:

y=-2x-3

Step-by-step explanation:

Since the slope is -2, we can make an equation : y=-2x+b

Now plug in the point given to find b.

1=-2(-2)+b

1=4+b

b=-3

so, the equation is y=-2x-3

The correct answer is: y - 1= -2(x + 2)

The table below shows the values for the function
y = f(x).

Complete the table for the
function
y = f(1/5x).

Answers

Given:

The table of values of function [tex]y=f(x)[/tex] is given.

To find:

The table of values of function [tex]y=f(\dfrac{1}{5}x)[/tex].

Solution:

The horizontal stretch is defined as:

[tex]g(x)=f(ax), 0<a<1[/tex]

Here, f(x) is horizontally stretched by factor a to get g(x).

The given function is:

[tex]y=f(\dfrac{1}{5}x)[/tex]

It means the function [tex]y=f(x)[/tex] is horizontally stretched by factor [tex]\dfrac{1}{5}[/tex] to get [tex]y=f(\dfrac{1}{5}x)[/tex].

So, we need to multiply the given x-values by 5 to get the required table of values.

Therefore, the required table of values is:

Solve for line segment AB

Answers

Answer:

AB = 32

Step-by-step explanation:

Given:

AD = 40

CD = 9

Required:

Find the length of segment AB

Solution:

BC and CD are radius of the circle. Therefore,

BC = CD = 9

AB = AC - BC

AB = AC - 9

We need to find AC

Since AD is tangent, CD is perpendicular to AD, this means that <D is a right angle. This makes ∆ADC a right triangle.

Therefore, we can apply Pythagorean theorem to find AC.

Thus:

AC² = AD² + CD²

AC² = 40² + 9²

AC² = 1,681

AC = √1,681

AC = 41

Let's find BC:

AB = AC - 9

Plug in the value of AC

AB = 41 - 9

AB = 32
