!!HELP!!A stage designer paid $4 per square foot for flooring to be used
in a square room. If the designer spent $600 on the flooring, about how long is a
side of the room? Round to the nearest foot.

• How is the area of a square related to its side length?

• How can you estimate the length of a side of a square?

Answers

Answer 1
Answer:

The area of a square relates to its side length as Area = Side Length × Side Length. To estimate a side length, knowing $4/sq ft cost and $600 spent, Side Length ≈ 12 feet.

The area of a square is related to its side length by the formula:

Area = Side Length × Side Length

or Area = Side Length²

To estimate the length of a side of a square,

use the given information that the designer paid $4 per square foot for flooring and spent $600 on the flooring.

The cost of the flooring is directly proportional to its area, which is determined by the square of the side length.

Let's set up an equation using the cost and area:

Cost of flooring = Cost per square foot × Area

$600 = $4/sq ft × Side Length²

Solving for Side Length²

Side Length² = $600 / $4/sq ft

Side Length² = 150 sq ft

Taking the square root of both sides to find the side length:

Side Length ≈ √150

Side Length ≈ 12.25 feet

Rounded to the nearest foot, the side length of the room is approximately 12 feet.

Therefore, the estimated length of a side of the room is about 12 feet.

A​ person's blood pressure is monitored by taking 8 readings daily. The probability distribution of his reading had a mean of 129 and a standard deviation of 7. a. Each observation behaves as a random sample. Find the mean and the standard deviation of the sampling distribution of the sample mean for the eight observations each day. b. Suppose that the probability distribution of his blood pressure reading is normal. What is the shape of the sampling​ distribution? c. Refer to​ (b). Find the probability that the sample mean exceeds 140.

Answers

Answer:

a) \mu_(\bar X)= 129

\sigma_(\bar X)= (7)/(√(8))=2.475

b) If the distribution is normal then the sampling distribution would be bell shaped and normal

c) P(\bar X >140)

And we can use the z score formula given by:

z =(\bar X -\mu)/(\sigma_(\bar X))

And replacing we got:

z =(140-129)/(2.475)= 4.44

And then we can find the probability using the complement rule and the normal standard distribution or excel and we got:

P(\bar X>140) = P(Z>4.44) =1-P(z<4.44) \approx 0

Step-by-step explanation:

For this case we have the following info:

n=8 represent the sample size

\bar X=129 the sample mean

s=7 the standard deviation

Part a

If we assume that the distirbution is bell shaped then we can find the parameters like this:

\mu_(\bar X)= 129

\sigma_(\bar X)= (7)/(√(8))=2.475

Part b

If the distribution is normal then the sampling distribution would be bell shaped and normal

Part c

We want this probability:

P(\bar X >140)

And we can use the z score formula given by:

z =(\bar X -\mu)/(\sigma_(\bar X))

And replacing we got:

z =(140-129)/(2.475)= 4.44

And then we can find the probability using the complement rule and the normal standard distribution or excel and we got:

P(\bar X>140) = P(Z>4.44) =1-P(z<4.44) \approx 0
