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>
Answer:
138
Step-by-step explanation:
152+125=277
277-135=142
around 138
Answer:
A yes
Step-by-step explanation:
you use the pythagorean theorem
I get:
24 = 3x-12
add 12 to both sides
36 = 3x
divide each side by 3 and you will get 12
- - To find a "what number is x% of x"
You have to first change 35% into a decimal.
35%=0.35
Now 0.35*22=7.7
Therefore your final answer is 7.7
