Xelga [282]
In this problem, since we are trying to find Sam's monthly net income, we just need to multiply his weekly net income (which is after all the deductions come out) by how many times he gets paid! Because he gets paid 4 times, we just need to multiply $654.48 by 4! The you should get an answer of $2617.92, which is Sam's monthly net income!

tatuchka [14]

Answer: C . H_0:\mu\geq7.5 and H_a:\mu

Step-by-step explanation:

Definition:

Null hypothesis(H_0) is a statement about the population parameter according to the objective raised by the researcher . It contains '=' , '≤' and  '≥' signs.

Alternative hypothesis(H_a) is also a statement about the population parameter but against null hypothesis  . It contains '≠' , '<' and  '>' signs.

Let \mu be the average customer waiting time for the population.

Given : The average customer waiting time at a fast food restaurant has been 7.5 minutes.

Objective of test : After using new system ,  the average customer waiting time is at least 7.5 or less than 7.5.

Then, the null and alternative hypothesis for this scenario will be :

H_0:\mu\geq7.5

H_a:\mu

Given f(x)=4x^3+7x^2-7x-10 factor f(x), given that -1 is a zero
stira [4]
If - 1 is a zero then
(x + 1)
is a factor.

Dividing with this factor using the long division approach, we get the quadratic factor to be,

4 {x}^{2}  + 3x - 10
(see attachment).

We can rewrite the polynomial as
f(x) = (x  + 1)(4 {x}^{2}  + 3x - 10)

We can further factor as

f(x) = (x + 1)(4 {x}^{2}  - 5x + 8x - 10)
That is

f(x) = (x + 1)(x  +  2)(4x - 5)
