Answer:
Step-by-step explanation:
Let
be the cost of renting from Mozart's Music Store for
years, and
be the cost of renting from Bach's Music Store for
years.
From the problem statement, we can come up with the following equations:
![M(x) = 34(12x)](https://tex.z-dn.net/?f=M%28x%29%20%3D%2034%2812x%29)
![B(x) = 30(12x) + 48x](https://tex.z-dn.net/?f=B%28x%29%20%3D%2030%2812x%29%20%2B%2048x%20)
Plugging in
for each equation, we can get the answer:
![M(9) = 34(12 * 9)](https://tex.z-dn.net/?f=M%289%29%20%3D%2034%2812%20%2A%209%29)
![M(9) = 34(108)](https://tex.z-dn.net/?f=M%289%29%20%3D%2034%28108%29)
![M(9) = 3672](https://tex.z-dn.net/?f=M%289%29%20%3D%203672)
![B(9) = 30(12 * 9) + 48(9)](https://tex.z-dn.net/?f=B%289%29%20%3D%2030%2812%20%2A%209%29%20%2B%2048%289%29)
![B(9) = 30(108) + 432](https://tex.z-dn.net/?f=B%289%29%20%3D%2030%28108%29%20%2B%20432)
![B(9) = 3240 + 432](https://tex.z-dn.net/?f=B%289%29%20%3D%203240%20%2B%20432)
![B(9) = 3672](https://tex.z-dn.net/?f=B%289%29%20%3D%203672)
From this, we can see that the value is equal for both stores.

Step-by-step explanatnation
We are given the following in the question:
Sample size, n = 200
\hat{p} = 65\% = 0.65
Margin of error =
\pm 6.75\% = \pm 0.0675
\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}
\hat{p}\pm \text{Margin of error}
Putting values:
(0.65 \pm 0.0675)\\=(0.5825,0.7175)

Bottom
Step-by-step explanation:
Because the water will direct fill down
too easy
Option B,C and D are correct.
Step-by-step explanation:
We need to determine which statements are true about ![2gh-(3+7)+\frac{x}{4}](https://tex.z-dn.net/?f=2gh-%283%2B7%29%2B%5Cfrac%7Bx%7D%7B4%7D)
Checking the options:
The term x/4 is quotient of 2 variables is not true.
2gh-(3+7) is the difference of two terms is true
Co-efficient of the expression are 2 and 1/4 is true because, co-efficient are terms that comes with variables.
The expression 3+7 is sum of two numbers is also true.
Option B,C and D are correct.
