Answer:

4 dozen- 1.94

5 dozen- 2.40

---------------

9 dozen - 4.32

10 dozen- 4.80

Step-by-step explanation:

The rate is 0.48, each dozen is 0.48 and as the dozens add up, you just add 0.48 to the previous dozen to get the next one.

Your expression would look like this:

x + 0.48 = y

x being the previous dozen and the y being the next one after adding 0.48

Part B:

The x axis will have the categories of quiz scores! The y axis will show how many students got that score.

We then put the categories from smallest to largest along the x axis. We will also put the numbers that go with the categories above the category!

Done! you have made your histogram!

A company manufactures televisions. The average weight of the televisions is 5 pounds with a standard deviation of 0.1 pound. As

Semenov [28]

Answer:

$0.2564\text{ pounds}$

Step-by-step explanation:

The 90th percentile of a normally distributed curve occurs at 1.282 standard deviations. Similarly, the 10th percentile of a normally distributed curve occurs at -1.282 standard deviations.

To find the $X$ percentile for the television weights, use the formula:

$X=\mu +k\sigma$ , where $\mu$ is the average of the set, $k$ is some constant relevant to the percentile you're finding, and $\sigma$ is one standard deviation.

As I mentioned previously, 90th percentile occurs at 1.282 standard deviations. The average of the set and one standard deviation is already given. Substitute $\mu=5$ , $k=1.282$ , and $\sigma=0.1$ :

$X=5+(1.282)(0.1)=5.1282$

Therefore, the 90th percentile weight is 5.1282 pounds.

Repeat the process for calculating the 10th percentile weight:

$X=5+(-1.282)(0.1)=4.8718$

The difference between these two weights is $5.1282-4.8718=\boxed{0.2564\text{ pounds}}$ .
