Answer:

x = 0.6 * 50

Step-by-step explanation:

x = 60% of 50

x = 60% * 50

x = 0.6 * 50

Answer:

60% of 50 = 60 / 100 × 50 = ⅗ × 50 = 150 / 5 = 30

________

x% of y = x / 100 × y = xy / 100

Answer:

9 and 6

Step-by-step explanation:

Write down the system.

The two numbers are x and y.

We are therefore given:

x+y=15

x-y=3

I will solve this for elimination since it is already setup for it.

I will add the columns since both equations are in the same form.

2x+0y=18

2x      =18

Divide both sides by 2:

x        =18/2

Simplify:

x        =9

So if x+y=15 and x=9, then y=6.

The two numbers are 9 and 6.

Test:

9+6=15

9-6=3

Suppose that weekly income of migrant workers doing agricultural labor in Florida has a distribution with a mean of $520 and a s
Arada [10]

Answer:

z = \frac{500-520}{\frac{90}{\sqrt{100}}}= -2.22

And we can find this probability using the normal standard distribution and we got:

P(z

Step-by-step explanation:

For this case we have the foolowing parameters given:

\mu = 520 represent the mean

\sigma =90 represent the standard deviation

n = 100 the sample size selected

And for this case since the sample size is large enough (n>30) we can apply the central limit theorem and the distribution for the sample mean would be given by:

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

And we want to find this probability:

P(\bar X

We can use the z score formula given by:

z = \frac{500-520}{\frac{90}{\sqrt{100}}}= -2.22

And we can find this probability using the normal standard distribution and we got:

P(z
