Answer:

The perimeter of a rectangle is:

  • P = 33n+3

Step-by-step explanation:

Given

The width of a rectangle w =  8n - 8.5 feet

The length of a rectangle l = 8.5n + 10 feet

To determine

The perimeter of a rectangle = P = ?

The perimeter of a rectangle can be determined using the formula

P = 2(l+w)

substitute l = 8.5n + 10 and w = 8n - 8.5

P=2\left(8.5n+10+8n-8.5\right)

   =2\left(16.5n+10-8.5\right)

   =2\left(16.5n+1.5\right)

   =33n+3

Therefore, the perimeter of a rectangle is:

  • P = 33n+3

Construct the 95% confidence interval for the population mean using the appropriate distributions. a. A random sample of 50 peop
SSSSS [86.1K]

Answer: 95% confidence interval would be (26.01,29.39).

Step-by-step explanation:

Since we have given that

n = 50

Mean = 27.7

Standard deviation = 6.12

We need to construct 95% confidence interval for the population.

so, z = 1.96

So, it becomes,

\bar{x}\pm z\times \dfrac{\sigma}{\sqrt{n}}\\\\=27.7\pm 1.96\times \dfrac{6.12}{\sqrt{50}}\\\\=27.7 \pm 1.69\\\\=(27.7-1.69,27.7+1.69)\\\\=(26.01,29.39)

Hence, 95% confidence interval would be (26.01,29.39).

Shade a model that shows 0.674
Ratling [72]
0.674 means that it 674/1000

which mean that if the model consists of 1000 squares, you have to shade 674 of the squares.

If the model consists of 500 squares, you have to shade 337 of the squares  ( you get the number after dividing both 674 and 1000 with 2)
