Answer:8.6
Step-by-step explanation:
The sides are:
A=135
B=95
C=130
L=100
W=20
And the perimeter is: 360
Further explanation:
Given that both figures have same parameter
Let P1 be the perimeter of the triangle and P2 be the perimeter of the rectangle
Then
P1=P2
Let the sides of triangle be
A = x+55
B= x+15
C = x+50
and
Sides of rectangle be
L = x+20
W = x
The sides are:
A=135
B=95
C=130
L=100
W=20
And the perimeter is: 360

To solve, first you need to figure out what 13% of 39,800 is (5,174).
Then, add that to the base pay of 42,500 and you get B: $47,674
The graph would look like this
Answer:
The interval from the sample of size 400 will be approximately <u>One -half as wide</u> as the interval from the sample of size 100
Step-by-step explanation:
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the 95% confidence interval is dependent on the value of the margin of error at a constant sample mean or sample proportion
Generally the margin of error is mathematically represented as
Here assume that is constant so
=>
=>
So let and
=>
=>
=>
So From this we see that the confidence interval for a sample size of 400 will be half that with a sample size of 100
