Answer:
(b) 19% is a parameter, 22% is a statistic.
Step-by-step explanation:
-A parameter is defined as characteristic of a population under study.
In this case , the population is all cars manufactured and the characteristic of whiteness is exhibited by 19% of them.
#A statistic is a characteristic of sample.
-In this case the sample size is 100 and the statistic is 22% of them are white.
=>A statistic is usually taken or used as a representation of the entire population.

Answer:
It is the one on the bottom right
Step-by-step explanation:
First of all, we have to start at (0,0), so we can cross out the one on the top left and top right, as they does not.
Also, the one on the bottom right does not go back to the ground, though just stays in the air, but the one on the bottom right dows go back to the ground.
So, its the one on the bottom right
So,
The problem tells us that the length of the rectangle is 5 feet more than twice the width.
Mathematically:
length = 5 + 2width
l = 5 + 2w
We know that the perimeter is 2l + 2w.
2l + 2w = 130
2(5 + 2w) + 2w = 130
Distribute
10 + 4w + 2w = 130
Collect Like Terms
10 + 6w = 130
Subtract 10 from both sides
6w = 120
Divide both sides by 6
w = 20
The width is 20.
Since
l = 5 + 2w
Substitute
l = 5 + 2(20)
Multiply
l = 5 + 40
Collect Like Terms
l = 45
The length is 45.
Check
2l + 2w = 130
2(45) + 2(20) = 130
90 + 40 = 130
130 = 130
Width: 20 ft.
Length: 45 ft.
