Answer:

Step-by-step explanation:
The complete question in the attached figure
we have

we know that
(ab)(x) is equal to the product of a(x) and b(x)
so

Applying distributive property



This is a quadratic equation
The other expressions not produce a quadratic equation

so
Answer:
C i think
Step-by-step explanation:
divide both sides by b, then multiply both sides by 2 and get 2A/b =h
Answer:
H0: p1-p2=0
Ha: p1-p2≠0
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
Step-by-step explanation:
Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .
Ha: p1-p2≠0
The null hypothesis is
H0: p1-p2=0 i.e these data do not provide strong evidence the rate of sleep deprivation is different for the two states.
where p1 = as population 1 of California
p2= as population 2 of Oregon
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
which will also give the same results as above and a two tailed test will be performed for both hypotheses.
