AlexFokin [52]2 years ago
8 0

Answer:

z = 4.8

m = 5 1/3

Step-by-step explanation:

Here, we want to get and z

We use the principle of similar triangles

5/3 = 8/z

5z = 24

z = 24/5

z = 4.8

To get m;

3/m-2 = 4.8/m

3m = 4.8(m-2)

3m = 4.8m - 9.6

4.8m - 3m = 9.6

1.8m = 9.6

m = 9.6/1.8

m = 5 1/3

REY [17]
It is a pattern so 2*3=6
3 times 4 is 12
4 times 5 is 20 
5 times 6 is 30
6 times 7 is 42
so, 9 times 8 is 72.

The U.S. Bureau of Labor Statistics reports that of persons who usually work full-time, the average number of hours worked per w
alukav5142 [94]

Answer:

The standard deviation of number of hours worked per week for these workers is 3.91.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by

Z = \frac{X - \mu}{\sigma}

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.

In this problem we have that:

The average number of hours worked per week is 43.4, so \mu = 43.4.

Suppose 12% of these workers work more than 48 hours. Based on this percentage, what is the standard deviation of number of hours worked per week for these workers.

This means that the Z score of X = 48 has a pvalue of 0.88. This is Z between 1.17 and 1.18. So we use Z = 1.175.

Z = \frac{X - \mu}{\sigma}

1.175 = \frac{48 - 43.4}{\sigma}

1.175\sigma = 4.6

\sigma = \frac{4.6}{1.175}

\sigma = 3.91

The standard deviation of number of hours worked per week for these workers is 3.91.
