The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
Answer:
Option E) 61.6
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100 bushels per acre
Standard Deviation, σ = 30 bushels per acre
We assume that the distribution of yield is a bell shaped distribution that is a normal distribution.
Formula:

P(X>x) = 0.90
We have to find the value of x such that the probability is 0.90
P(X > x)
Calculation the value from standard normal table, we have,

Hence, the yield of 61.6 bushels per acre or more would save the seed.
C) Protects against their environmental
Answer:
6 7/12 hours in June
Step-by-step explanation:
Find the answer to this question by subtracting 6 4/6 hours from the total 13 1/4 hours:
13 1/4 hours is equivalent to 12 5/4 hours (we borrow '1' from 13 1/4).
Thus, we have
12 5/4 hours Note that the LCD of 5/4 and 4/6 is 12. Thus
- 6 4/6 hours we have
12 15/12 hours
- 6 8/12 hours

6 7/12 hours
