Answer:1/6
Step-by-step explanation:
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.
7 hours
explanation:
30>or equal to 3h+9
subtract non on both sides:
21>or =to 3h
divide by 3:
7>or=to h
This is a quadratic function that can also be expressed as -6x^2 - 24x - 34.
You could also graph this using the vertex of (-2, -10)
Answer:
equation first is correct
