Assuming the certification exam scores of a given population are normally distributed with a mean (µ) = 500 and a standard deviation (σ) = 100. What is the 85th percentile (upper 15%) of the certification exam scores?

how am i supposed to answer

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

=

x=0.8898305 is the answer to that equation
