Answer:
34.134%
Step-by-step explanation:
Given :
Normal distribution ;
Mean, m = 100 ; Standard deviation, s = 10
Percentage score between 90 and 100
P(90 ≤ x ≤ 100)
Recall : Zscore = (x - m) / s
P[(90 - 100) / 10 ; (100 - 100) / 10]
P[(10/10 ; 0 / 10)]
P(Z ≤ 1) - P(Z≤0) (Using Z probability calculator)
0.84134 - 0.5
= 0.34134
= 0.34134 * 100%
= 34.134%
Answer:
<h2>-10.4 is the right answer.</h2>
13 of 25 would mean that the percent of error is 86%
7 minus the product of 2 and x in algebra is:
7 - 2x
The answer is: " 12 months " .
