Answer:

See below.

Step-by-step explanation:

Let x equal each of the values on the table, and find the value of the function for that value of x.

f(x) = 5x - 5

x = -4

f(-4) = 5(-4) - 5

f(-4) = -20 - 5

f(-4) = -25

x = 0

f(0) = 5(0) - 5

f(0) = 0 - 5

f(0) = -5

x = 1

f(1) = 5(1) - 5

f(1) = 5 - 5

f(1) = 0

x = 3

f(3) = 5(3) - 5

f(3) = 15 - 5

f(3) = 10

x = 5

f(5) = 5(5) - 5

f(5) = 25 - 5

f(5) = 20

x f(x)

5 20

Step-by-step explanation:

$\tt f(x)=5x-5$

$\tt f(-4)=5(-4)-5=-25$

$\tt f(0)=5(0)-5=-5$

$\tt f(1)=5(1)-5=0$

$\tt f(3)=5(3)-5=10$

$\tt f(3)=5(3)-5=20$

Hope it helps! :)

Which score indicates the highest relative position? I. A score of 2.6 on a test with X = 5.0 and s = 1.6 II. A score of 650 on

Answer:

A score of 2.6 on a test with $\bar X$ = 5.0 and s = 1.6 and A score of 48 on a test with $\bar X$ = 57 and s = 6 indicate the highest relative position.

Step-by-step explanation:

We are given the following:

I. A score of 2.6 on a test with $\bar X$ = 5.0 and s = 1.6

II. A score of 650 on a test with $\bar X$ = 800 and s = 200

III. A score of 48 on a test with $\bar X$ = 57 and s = 6

And we have to find that which score indicates the highest relative position.

For finding in which score indicates the highest relative position, we will find the z score for each of the score on a test because the higher the z score, it indicates the highest relative position.

The z-score probability distribution is given by;

Z = $\frac{X-\bar X}{s}$ ~ N(0,1)

where, $\bar X$ = mean score

s = standard deviation

X = each score on a test

The z-score of First condition is calculated as;

Since we are given that a score of 2.6 on a test with $\bar X$ = 5.0 and s = 1.6,

So, z-score = $\frac{2.6-5}{1.6}$ = -1.5 {where $\bar X = 5.0$ and s = 1.6 }

The z-score of Second condition is calculated as;

Since we are given that a score of 650 on a test with $\bar X$ = 800 and s = 200,

So, z-score = $\frac{650-800}{200}$ = -0.75 {where $\bar X = 800$ and s = 200 }

The z-score of Third condition is calculated as;

Since we are given that a score of 48 on a test with $\bar X$ = 57 and s = 6,

So, z-score = $\frac{48-57}{6}$ = -1.5 {where $\bar X = 57$ and s = 6 }

AS we can clearly see that the z score of First and third condition are equally likely higher as compared to Second condition so it can be stated that A score of 2.6 on a test with $\bar X$ = 5.0 and s = 1.6 and A score of 48 on a test with $\bar X$ = 57 and s = 6 indicate the highest relative position.
