We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
Answer:
B. Yes, there is reason. The TV audience might not be representative of the population.
Step-by-step explanation:
The question "Do you support new national mileage standards forautomobiles?" is asked to the TV audience.

Thus the results cannot represent the whole population
Convert 3/4 to a denominator of 8 by multiplying by two, getting you:
6/8 + 1/8
Add those and you get D) 7/8
You would multiply 2 1/2 and 3 3/4, which would give you 9.375 or as a mixed number 9 7/8
