Answer:

31.74 million people were employed.

Step-by-step explanation:

The unemployment rate is the number of unemployed people divided by the size of the labor force.

So the first step to solve this problem is finding the size of the country's labor force.

Suppose some country had an adult population of about 46 million, a labor-force participation rate of 75 percent.

So the size of the country labor force is:

0.75 * 46 million = 34.5 million people.

Unemployment rate of 8 percent. How many people were employed?

This means that 100 - 8 = 92 percent of people were employed. Remembering, this considers only the labor force, of 34.5 million people. So

0.92 * 34.5 million = 31.74 million

31.74 million people were employed.

Suppose that we will randomly select a sample of 106 measurements from a population having a mean equal to 19 and a standard dev
svet-max [94.6K]

Answer:

z =\frac{18.45-19}{\frac{7}{\sqrt{106}}}= -0.809

And if we use the normal standard distribution or excel we got:

P(z

Step-by-step explanation:

For this case we have the following info given:

\mu = 19 represent the mean

\sigma = 7 represent the standard deviation

n = 106 represent the sample size

The distribution for the sample size if we use the central limit theorem (n>30) is given by:

\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})

And for this case we want to find the following probability:

P(\bar X< 18.45)

And for this case we can use the z score formula given by:

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

And replacing we got:

z =\frac{18.45-19}{\frac{7}{\sqrt{106}}}= -0.809

And if we use the normal standard distribution or excel we got:

P(z

Explain how to solve 4|3x-1|+1=8​
denis-greek [22]

4|3x - 1| + 1 = 8

4|3x - 1| = 8 - 1

4|3x - 1| = 7

|3x - 1| = 7/4

Now lets think, we have 3x - 1 in module, so either its 7/4 or -7/4, we will have 7/4 at the end because of it, so we may have 2 solutions in this case:

3x - 1 = 7/4

and

3x - 1 = -7/4

So let's see:

3x - 1 = 7/4

3x = 7/4 + 1

3x = 11/4

x = 11/12

3x - 1 = -7/4

3x = -7/4 + 1

3x = -3/4

x = -1/4

So we have two possible answers, x = 11/2 and x = -1/4
