It would take 40 minutes.
You multiply the time it took her to run one mile by the number of miles.
8x5=40
Hope this helps

38. The volume of a cylinder is 97 ft3. If the dimensions are doubled, what will be the new volume?
asambeis [7]

Volume is cubed. If the dimensions are doubled, cube the scale factor:

2^3 = 8

The volume will increase by a scale of 8.

The new volume would be 97 x 8 = 776 ft^3

According to a recent​ survey, the population distribution of number of years of education for​ self-employed individuals in a c
creativ13 [48]

Answer:

a) X: number of years of education

b) Sample mean = 13.5, Sample standard deviation = 0.4

c) Sample mean = 13.5, Sample standard deviation = 0.2

d) Decrease the sample standard deviation

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 13.5 years

Standard deviation,σ = 2.8 years

a) random variable X

X: number of years of education

Central limit theorem:

If large random samples are drawn from population with mean \mu and standard deviation \sigma, then the distribution of sample mean will be normally distributed with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}

b) mean and the standard for a random sample of size 49

\mu_{\bar{x}} = \mu = 13.5\\\\\sigma_{\bar{x}} = \dfrac{\sigma}{\sqrt{n}} = \dfrac{2.8}{\sqrt{49}} = 0.4

c) mean and the standard for a random sample of size 196

\mu_{\bar{x}} = \mu = 13.5\\\\\sigma_{\bar{x}} = \dfrac{\sigma}{\sqrt{n}} = \dfrac{2.8}{\sqrt{196}} = 0.2

d) Effect of increasing n

As the sample size increases, the standard error that is the sample standard deviation decreases. Thus, quadrupling sample size will half the standard deviation.

Answer:

y=17

Step-by-step explanation:

So the shape is a square, which means 1 is equal to 90 degrees. So, 4y+22=90

When you solve, you get 17:

4y=68

y=17
