ANSWER ASAP GIVING BRAINLIEST AND STUFF!

AURORKA [14]

Answer:

You could make a proportion, and divide or subtract the colors you like the least. Then, take the ones that you like the least away and put them in a separate place away from the others. For example: You have five colors, right? Ok, lets say your colors are blue, charcoal gray, yellow, green, and lilac.

Lets say your favorites are charcoal gray, lilac, and blue. (3/5)

So you put yellow and green to the side (2/5)

For example: You have 6 wallpaper patterns, right? Lets say your patters are flowers, dots, lines, stars, circles, and zigzags.

Lets say your favorites are flowers and stars. (2/6 or 1/3)

So you put dots, lines, circles, and zigzags to the side. (4/6 or 2/3)

Now, I want you to narrow your favorites down to what you favor more out of them. Now you have 3 paint colors, right? Your colors are charcoal gray, blue, and lilac. You need to narrow it down to 1 favorite. Lets say you choose the the lilac best.

Now you have 2 patterns, right? Your patterns are flowers and stars. You need to narrow it down to your favorite pattern. Lets say you choose the stars.

So, you will paint your wall lilac with the pattern of stars.

Evaluated to square

denis-greek [22]

Step-by-step explanation:

The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9.

Using traditional methods it takes 92 hours to receive an advanced flying license. A new training technique using Computer Aided

DanielleElmas [232]

Answer:

The value of the test statistic is z = 1.39.

The p-value of the test is 0.0823 > 0.05, which means that there is not evidence at the 0.05 level that the technique lengthens the training time.

Step-by-step explanation:

Using traditional methods it takes 92 hours to receive an advanced flying license.

This means that at the null hypothesis, it is tested if the mean is of 92, that is:

$H_0: \mu = 92$

Test if there is evidence that the technique lengthens the training time

At the alternative hypothesis, it is tested if the mean is more than 92, that is:

$H_1: \mu > 92$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

92 is tested at the null hypothesis:

This means that $\mu = 92$

A researcher used the technique on 70 students and observed that they had a mean of 93 hours. Assume the population variance is known to be 36.

This means that $n = 70, X = 93, \sigma = \sqrt{36} = 6$

Value of the test statistic:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{93 - 92}{\frac{6}{\sqrt{70}}}$

$z = 1.39$

The value of the test statistic is z = 1.39.

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean above 93, which is 1 subtracted by the p-value of z = 1.39.

Looking at the z-table, z = 1.39 has a p-value of 0.9177.

1 - 0.9177 = 0.0823.

The p-value of the test is 0.0823 > 0.05, which means that there is not evidence at the 0.05 level that the technique lengthens the training time.

John bought new headphones originally listed for $ 80.99 . They are \(35\%)| off. Which equation can be used to find the amount

Katarina [22]

Answer:

$28.35

Step-by-step explanation:

The headphones are $80.99 and are 35% off. To find the amount he will save, change the 35% to a decimal by moving it two times to the left, which is 0.35. Multiply 80.99 and 0.35 to get 28.3465. Round to get $28.35.
