Stephanie is trying to figure out the sample size of an experiment. She knows the population SD is 41.5 and the SD of the sample averages is 2.7. What is the sample size of the experiment? a.) .00367718446
b.) 15.37
c.) 236.24

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
