Step-by-step explanation:
I found this by first adding the fractions up, which gets us 9/6 or 1 and 3/6 or 1/2
12+8+15+1 1/2
12+8=20
20+15=35
35+1 1/2= 36 and 1/2 Inches

Answer: b) 84
Step-by-step explanation:
Let p be the prior estimate of the required proportion.
As per given , we have
p =0.5 (The probability of getting heads on a fair coin is 0.5)
Significance level : 
Critical z-value (using z-value table ) : 
Confidence interval width : w= 0.18
Thus , the margin of error : 
Formula to find the sample size ( if prior estimate of proportion is known.):-

Substitute the values , we get

Simplify ,
[Round of to the next whole number.]
Hence, the number of times we would have to flip the coin =<u>84</u>
hence, the correct answer is b) 84
X = B.......x - 17 = A
x + x - 17 = 87
2x - 17 = 87
2x = 87 + 17
2x = 104
x = 104/2
x = 52........so state B has 52 electoral votes
x - 17 = A
52 - 17 = A
35 = A.....so state A has 35 electoral votes
