Red and grey bricks were used to build a decorative wall. The number of red bricks/number of grey bricks was 5/2. There were 140

Airida [17]

To find the number of red bricks used, you can create a part to part to whole ratio from the simple ratio of red to grey brick they give.

Then, use the total to create an equivalent ratio with the actual total number of bricks (140).

5 red 100 red
2 grey = 40 grey
7 total 140 total

Each time, the simple ratio was multiplied by 20 to get the actual totals for each color.

There were 100 red bricks used.

The branch manager of a clothing store is analyzing the average total bill of sale for his location. the national manager has co

Using the Central Limit Theorem, the branch manager can be 95% certain that the sample mean will fall within $1.034 of the mean.

<h3>What does the Central Limit Theorem state?</h3>

It states that the sampling distribution of sample means of size n has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

By the Empirical Rule, 95% of the sample means fall within 2 standard errors of the mean.

In this problem, we have that the standard deviation and the sample size are given as follows:

$\sigma = 10.34, n = 400$

Hence the standard error is given by:

[tex]s = \frac{10.34}{\sqrt{400}} = 0.517.

Two standard errors is represented by:

2 x 0.517 = $1.034.

Hence, the branch manager can be 95% certain that the sample mean will fall within $1.034 of the mean.
