It is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Step-by-step answer:
standard deviation (sigma) = 12 inches
mean (mu) = 90 inches.
For 36 years, the standard error of the mean is
e = sigma / sqrt(n) = 12" / sqrt(36) = 2".
Deviation from the mean
= 92.8 -90 = 2.8
Since the standard error of the mean follows the normal distribution, we have
Z=(92.8-90)/2 = 1.4
Looking up the normal distribution tables, or check R, we find
P(Z>1.4) = 1-P(Z<1.4) = 1-0.9192433 = 0.08075666
Answer: P(snowfall>92.8) = 0.0808 (to four decimal places)

Im sorry if i didn't answer your question but i did not get what you were saying but here is an image that can maybe help you
Answer:
25
Step-by-step explanation:
(3^3)-2=25
step by step
(3^3)=3^3
=3^3-2
=3^3=27
=27-2
so if we subtract the #: 27-2
The answer will be 25
16+15
combine like terms
the simplified answer is 31
