Answer:
Width= 12 yards
Length= 24 yards
Step-by-step explanation:
Perimeter of a rectangle= 2(length + width)
Let
w= width
Twice as long as it is wide
Length= 2w
Perimeter of the rectangle= 72 yards
Perimeter of a rectangle= 2(length + width)
72 = 2(2w + w)
72 = 4w + 2w
72 = 6w
Divide both sides by 6
72/6 = w
12= w
w=12
Therefore,
Width= 12 yards
Length= 2w
=2(12)
=24 yards

Step-by-step explanation:
<u>Slope- intercept form:</u>
<u>Given</u>
- m = -38 and point (0, 10)
As per given point, y-intercept is b = 10
<u>So the equation is:</u>
In order to find the slope of a line, u must use the slope formula. Which is (y2-y1/x2-x1). For example if you had a set of coordinates that are (6,4) and (2,8) you would first sub the 8 from4 which gives you 4. The u do the same with 2 and 6 which gives u 4. After that you divide 4 by 4. and your answer is 1
Answer:
x=2
Step-by-step explanation:
just add 5 to both sides of the equation
Answer:
elsa's interval width will be greater than that of frank
Step-by-step explanation:
first of all we are told that both Elsa and Frank have the same sample proportion so their midpoint is also going to be the same.
now as the confidence level goes higher, so also would the margin of error increase. then the width of the confidence interval would rise so it can be more confident.
from this question elsa has a larger confidence level therefore her intervals width will be greater than franks own.
