Answer:
Step-by-step explanation:
Slope:
−
1
y-intercept:
23
<span>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.</span>
The answer is 9.857. This can be rounded.
<span>2(7/9)-(1/4) = 47/36 = 1 11/36</span>
