Answer:
Step-by-step explanation:
49 - 16 = 33
= 5.74
Give me a decimal to divide n I will help u
A)5.17
B)10.86
<em>I hope this helps</em>
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.
