Step-by-step explanation:
Hours worked = X
Money earned per hour = $8.75
Your answer would be A.
E.g.) Say that there is another part to this question.
You work for 3 hours, how much money would you earn after three hours? Use your equation "8.75x"
We know that "x" is equal to the hours worked, so plug in 3 for x.
8.75x = 8.75 *x
8.75 * 3= 26.25
So, if you worked 3 hours, your total pay would be $26.25 (Note: this is not part of your answer, just an example to show you how equations work)
Hope this helps :)

Step-by-step explanation:
Answer:
a) Option C) The score was 2.49 standard deviations higher than the mean score in the class.
b) 2.3%
Step-by-step explanation:
a) We are given that the distribution of test grades is a bell shaped distribution that is a normal distribution.
Formula:
Option C) The score was 2.49 standard deviations higher than the mean score in the class.
b) The z-score for a particular score is -2.
We have to evaluate
P(z < -2)
Calculating the value from normal z-table.
Thus, 2.3% of of the class scored lower than my friend.
Answer:
20.27
Step-by-step explanation:
I am sorry, but nobody can help until you put the question. Assuming it is Algebra, I can write this as function which would be y = 3x + 14.99 . Also, x has to be greather than zero because you cannot undownload a movie. y can also be something like f (m). m means the movies you downloaded. So it could also be f = 3m + 14.99 . If you want to graph it, I could do it for you.
