c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.

Step-by-step explanation:
do you need the fractions
1/7,2/7,3/7,4/7,5/7,6/7,1 or 7/7
1. 31,150 = x * 25,300
.. x = 31,150/25,300 = 1.231225... ≈ 1.23
Gary's 2017 salary is 1.23 times his 2015 salary.
2. 1.23 * 100% = 123%
Gary's 2017 salary is 123% of his 2015 salary.
MA/MN = MB/BP
MA = 46.2 -14
MA=32.2
so
MA/MN = MB/BP
32.2/46.2=x/72.6
46.2x = 72.6 * 32.2
46.2x = 2337.72
x = 2337.72 / 46.2
x = 50.6
