Answer:

200\ families

Step-by-step explanation:

Already, we are given 12% of our sample size as 24.

To find the sample size, we equate to find 100%.

Let sample size be denoted by t

If\  12\%=24\\100\%=t\\t=\frac{100\%\times24}{12\%}\\=200

Hence, the sample has 200 families.

frosja888 [35]

Answer:

h less-than 2

Step-by-step explanation:

Let

h ---> the number of hours

y ---> the total charge in dollars

we know that

The linear equation is slope intercept form is equal to

y=mh+b

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

we have

<em>Grayson</em>

The slope is equal to m=\$35\ per\ hour

The y-intercept is b=\$35

so

The total charge is equal to

y=35h+35 ----> equation A

<em>Ian</em>

The slope is equal to m=\$45\ per\ hour

The y-intercept is b=\$15

so

The total charge is equal to

y=45h+15 ----> equation B

For what number of hours does Grayson charge more than Ian?

The inequality that represent this situation is

35h+35 > 45h+15

solve for x

Group terms

35-15 > 45h-35h

20 > 10h

Divide by 10 both sides

2 > h

Rewrite the expression

h< 2\ hours ----> h less than 2 hours
