"assume that josh throws the discus 36 times. let y denote the sum of the lengths of the 36 throws.

1 answer:

6 0

Assuming that Josh throws the discus 36 times, the expected value of y will be the length each discus reaches for each throw all added together. Specifically, it will be discus throw one, plus discus throw two -- all the way to discus throw thirty-six. Adding all of those throws together will provide the expected value of Y.

Answer:

as x increases, f(x) decreases;
as x decreases,f(x) decreases

Step-by-step explanation:

The function is of even degree with a negative leading coefficient. f(x) will tend toward negative infinity as x gets larger or smaller. That is ...

as x increases, f(x) decreases;
as x decreases,f(x) decreases

_____

Even degree means the end behaviors are the same for both large and small x. Negative leading coefficient means the function value decreases for larger x.
