Answer:
Given hypothesis are
H0: A = 0.24
H1: Â ≠ 0.24
Here sample proportion  is used to express hypothesis instead of population proportion p.
The error is sample parameter  used in hypothesis [ It should be population parameter p or π )

Answer:
(x+9)(x+3)
x*x = x^2
x*3 = 3x
9*x = 9x
9*3 = 27
Answer = <em><u>x^2 + 12x + 27</u></em>

Answer:
6 Hours
Step-by-step explanation:
If the rate is -3, that means there is an hourly change of 3 degrees. To get to 18, you must divide 18 by 3.
18÷3=6
The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
