Answer:
They will expect the ratio below:
x/20 = 160/8, with x: population
Then
x = 20x160/8 = 400
Answer:
Below.
Step-by-step explanation:
If the length is x then the width is x-9 inches.
Perimeter
= 2L + 2W = 86
2x + 2(x - 9) = 86
4x - 18 = 86
4x = 104
x = 26
So the length is 26 inches and the width is 17 inches.
The advantage of using confidence interval can be associated with the population. A well-represented confidence interval of 95% can say that the parameter of the total population has been met. -Muhammad Imdadullah, https://itfeature.com
The disadvantage happens when the interval does not represent the parameter. If the interval is not within and was actually outside of it comes the problem. The interval is still randomly based and does not give the exact response of the population.

Answer:
12
Step-by-step explanation:
Use the PEMDAS
there is a parenthesis and exponents
9/3{(8) - 4)}
Multiply and divide 9/3= 3
Also subtract 8-4 = 4
3{8-4}
3(4)= 12
X= 27
Because
3x−4y=65
(3x−4y)+4y=65+4y
3x−4y+4y=4y+65
3x=4y+65
