To solve this problem we use the z test. The formula for z
score is:
z = (x – u) / s
where,
x = sample value = 13 and below
u = mean value = 27
s = standard deviation = 14
z = (13 – 27) / 14 = -1
using the z table to get the standard normal probabilities,
the p value at z = -1 is:
P = 0.1587
<span>This means that 15.87% that the discharge is 13 mg/L and
below.</span>
The answer is not a whole number depending on what the question allows as an answer it could be 6 remainder 6 or 6.4 as a decimal.

Answer:
c = 53 miles
Step-by-step explanation:
a^2 + b^2 = c^2
45^2 + 28^2 = c^2
2,025 + 784 = c^2
2809 = c^2
c = 53
