Given f(x)=x^2-x; find f(-5)

1 answer:

6 0

Plug in - 5 where X is.

f(- 5) = (- 5)^2 - ( - 5).

(- 5)( - 5) = 25 so now we have 25 - (- 5). Because there are two negatives back to back, the number becomes a positive so the equation becomes 25 + 5 = 30.

f(- 5) = 30.

Answer:

The hypotheses used in this situation

$H_0:\mu = 14.6$

$H_a:\mu \neq 14.6$

Step-by-step explanation:

We are given that Business Week reported that at the top 50 business schools, students studied an average of 14.6 hours.

Mean = $\mu = 14.6$

Claim : The amount UMSL students study is different from this 14.6 hour benchmark.

The hypotheses used in this situation

$H_0:\mu = 14.6$

$H_a:\mu \neq 14.6$
