Shelly has $175 to shop for jeans and sweaters. Each pair of jeans costs $25 and each
Ksju [112]

Answer:

3 jeans and 5 sweaters

Step-by-step explanation:

This is a solid guess

However, this is a straight forward question.

175 she has to spend all of it.

To make it an even number you minus 25.

Than you have 150, minus another 50.

You have 5 more clothes to buy, and $100 left.

You use the rest to buy sweaters, therefore spending all the money and getting 8 clothing.

A doctor wants to estimate the mean HDL cholesterol of all​ 20- to​ 29-year-old females. The number of subjects needed to estima
Ludmilka [50]

Answer:

n=(\frac{1.64(14.7)}{3})^2 =64.57 \approx 65

So the answer for this case would be n=65 rounded up to the nearest integer

And the sample size would decrease by 160-65=95 subjects

Step-by-step explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

\bar X represent the sample mean for the sample  

\mu population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size  

ME represent the margin of error

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

2) Solution to the problem

Since the new Confidence is 0.90 or 90%, the value of \alpha=0.1 and \alpha/2 =0.05, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that z_{\alpha/2}=1.64

Assuming that the deviation is known we can express the margin of error is given by this formula:

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}    (a)

And on this case we have that ME =\pm 3 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

n=(\frac{z_{\alpha/2} \sigma}{ME})^2   (b)

Replacing into formula (b) we got:

n=(\frac{1.64(14.7)}{3})^2 =64.57 \approx 65

So the answer for this case would be n=65 rounded up to the nearest integer

And the sample size would decrease by 160-65=95 subjects

EASY BRAINLIEST PLEASE HELP!!
DedPeter [7]

Answer:

C. AB = 5.8 cm

Step-by-step explanation:

In trapezoid ABCD, EF is the Midsegment.

.:. EF = {(AB+CD)

.:: 9.2 = {(AB + 12.6)

:: 9.2 x 2 = AB + 12.6

.. 18.4 = AB + 12.6

.. 18.4-12.6 = AB

:: AB = 5.8 cm
