Answer:
14.89% or 0.1489
Step-by-step explanation:
First, find the z-score for both 70 and 80 minutes and their corresponding percentile.

For X = 70 minutes:

This z-score is equivalent to the 7.445 th percentile, so the probability of a student finishing this exam in less than 70 minutes is 7.445%
or X = 80 minutes:

This z-score is equivalent to the 92.555 th percentile, so the probability of a student finishing this exam in more than 80 minutes is 100- 92.555 = 7.445%
Therefore, the probability (P) of a student finishing this exam in less than 70 minutes or more than 80 minutes is:
P = 7.445% + 7.445% = 14.89%
Answer:
B) 4 cm
Step-by-step explanation:
Pentagon ABCDE is 1.75 times larger than Pentagon LMNOP. In Pentagon ABCDE, side AB is 7 cm. The side across of it (DE) is also 7. Side DE is Side OP on Pentagon LMNOP. To solve for it, divide 7/1.75 to get 4.
