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

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:

  x         y

-20        7

 -5       -2

  0        3

 15       -4

30        5

Answer:

32768

Step-by-step explanation:

Each question has 2 options.

On a true/false test with one question, there are 2¹, or 2 possible answers

On a test with 2 questions, there are 2², or 4 possible answers.

On a test with 3 questions, there are 2³, or 8 possible answers.

So, 2¹⁵ = 32768 possible ways.

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

Answer:

x=17/9

Step-by-step explanation:

-7x-(-5-x)=-9(2x-1)

= -7x+5x+x= -18x+9

= -x= -18x+9

  +18x +18x

=17x=9

     x= 17/9

Hope this helps!

Answer:

-7x -(-5-x)=9(2x-1)

-7x+5x+x=18x+9

-x=-18x+18x

17x=9

x=17/9

Answer: The person who said it's D is right

Step-by-step explanation: I took the test and I got it right

The quadratic regression equation that fits these data is -1.107 X² +3.736 X +10.643 .

A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:

y=ax2+bx+c where a≠0 .

The best way to find this equation manually is by using the least squares method.

That is, we need to find the values of a ,b,  and  c such that the squared vertical distance between each point (xi,yi) and the quadratic curve y=ax2+bx+c is minimal.

After solving we get the values of a , b, and c and thus we form the equation

-1.107 X² +3.736 X +10.643

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.

Answer:

  (f -g)(x) = -3x^3 +x^2 +2x

Step-by-step explanation:

We assume the expression for g(x) has a typo, and the first term should be 3x^3.

(f -g)(x) = f(x) -g(x) = (3x^2 -2x -9) -(3x^3 +2x^2 -4x -9)

  = 3x^2 -2x -9 -3x^3 -2x^2 +4x +9

  = -3x^3 +(3 -2)x^2 +(-2+4)x +(-9+9)

(f -g)(x) = -3x^3 +x^2 +2x
