7. The length of a rectangle is two more than its width. The perimeter of the rectangle is 36 feet. What are the dimensions (len
Reika [66]

Step-by-step explanation:

length = x + 2

width = x

x + x + (x+2) + (x+2) = 36 ft

4x + 4 = 36 ft

4x = 32 ft

x = 32 ÷ 4

x = 8 ft

dimensions = length x width

= (x+2) × x

= (8+2) × 8

= 10 ft × 8 ft

A manufacturer produces a commodity where the length of the commodity has approximately normal distribution with a mean of 6.5 i
zavuch27 [327]

The probablity that the sample's mean length is greate than 6.3 inches is0.8446.

Given mean of 6.5 inches,standard deviation of 0.5 inches and sample size of 46.

We have to calculate the probability that the sample's mean length is greater than 6.3 inches is 0.8446.

Probability is the likeliness of happening an event. It lies between 0 and 1.

Probability is the number of items divided by the total number of items.

We have to use z statistic in this question because the sample size is greater than 30.

μ=6.5

σ=0.5

n=46

z=X-μ/σ

where μ is mean and

σ is standard deviation.

First we have to find the p value from 6.3 to 6.5 and then we have to add 0.5 to it to find the required probability.

z=6.3-6.5/0.5

=-0.2/0.5

=-0.4

p value from z table is 0.3446

Probability that the mean length is greater than 6.3inches is 0.3446+0.5=0.8446.

Hence the probability that the mean length is greater than 6.3 inches is 0.8446.
