Answer:
c.H0: pbar <= 0.20: HA: pbar > 0.20
Step-by-step explanation:
From the take on a sample of 60 homes from this neighborhood and 14 fitting in the criteria. The appropriate null and alternative hypotheses a is best expressed in option c.
H0: pbar <= 0.20: HA: pbar > 0.20
Answer:
The third one
Step-by-step explanation:
Ok, so if a zero is at r1, then a factor is (x-r1)
since there are no other roots, it must be only taht root
3rd degree so reaise it to the 3rd power
(x-r1)³
and the root is at x=-3
(x-(-3))³
(x+3)³
answer is f(x)=(x+3)³
also could be x³+27 where it factors to one real root and 2 complex roots
Direct variation is when is the same for each coordinate.
Indirect variation is when x · y is the same for each coordinate.

Answer:
y = x + 2
Step-by-step explanation:
First, find the rate of change [slope]:
-y₁ + y₂\-x₁ + x₂ = m
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y - 6 = x - 4
+ 6 + 6
_______________
y = x + 2 >> Line in <em>Slope-Intercept Form</em>
__________________________________________________________
y - 2 = x
+ 2 + 2
______________
y = x + 2 >> Line in <em>Slope-Intercept</em><em> </em><em>Form</em>
** You see? I told you that it would not matter which ordered pair you choose because you will always get the exact same result!!!
