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.
Answer:
B.(x-6)
Step-by-step explanation:
12/(x^2 - 11x+30) - 43/(x^2-6x)
12/((x - 5) (x - 6)) - 43/x(x-6) [Factoring the denominator]
Both have x-6 common in the denominator,
Answer:
5
Step-by-step explanation:
6-6/7
using pemdas it's:
