Answer:
B.-38
Step-by-step explanation:
2x - 18 = y ...(1)
x = -10 (Given)
Now,
Put the value of x in equation (1) we get,
2(-10) - 18 = y
-20 - 18 = y
-38 = y
<em><u>y = -38</u></em>
Thus, the value of y is -38

<u><em>The correct answer is:</em></u>16%.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>We use a z-score to answer this question.
<u>The formula for a z-score is:</u>
z=</span></span>

<span><span>,
where mue is the mean and sigma is the standard deviation.
<u>Using our information, we have:</u>
z=</span></span>

<span><span>.
Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.</span></span>
