Using the normal distribution, it is found that Sue will get a letter grade of B.
In a <em>normal distribution </em>with mean  and standard deviation
 and standard deviation  , the z-score of a measure X is given by:
, the z-score of a measure X is given by:

- It 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, which is the percentile of X.
In this problem, Sue got a grade of 0.85, hence  .
.
- Looking at the z-table, z = 0.85 has a p-value of 0.8023, hence she is approximately in the top 20%, which is below the top 15% but above the top 50%, hence she got a letter grade of B.

<u>Answer choices:</u>
A) Asher made errors in multiplication.
- No, the products are correct
B) Asher found multiples of 10, not factors of 10.
C) Asher should have multiplied 10 × 4 as well.
- No, 4 is not one of the factors of 10
D) Asher should have gotten this as the answer: 1, 2, 5, and 10.
- Yes, these are the true factors of 10
E) Asher should have gotten this as the answer: 10, 20, 30, 40, …

Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form
