<span>Let the length of one side of the rectangle be x.
Then the opposite side of the rectangle also has a length of x.
The sum of the other two sides must be 17 - 2x.
So the length of one of these sides is 8.5 - x.
The length of two sides of the rectangle are x and 8.5 - x.
To find the area, we need to multiply these two values.
A(x) = (x) (8.5 - x) = 8.5x - x^2</span>

The mean is 10 because you will add all the numbers and then divide the answer by 4
Answer:
DG = 17
Step-by-step explanation:
DG and EF are similar so sides are same.
2x - 7 = x + 5
2x - x = 5 + 7
x = 12
So DG = 2x - 7
= 2(12) - 7
= 24 - 7
= 17
Answer:
The true estimate of the average annual income of all 700 families living in a four square block section lies within the 92% confidence interval below
Step-by-step explanation:
From the question we are told that
The sample size is n = 50
The sample mean is 
The population standard deviation is 
From the question we are told the confidence level is 92% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 92% confidence interval is mathematically represented as
=>
=>
So the true estimate of the average annual income of all 700 families living in a four square block section lies within the 92% confidence interval
