B) $\$45.5$ she will earn for Smith family for 7 hours

C) It would take $12 \ hrs$ for Margie to make $\$78$ when babysitting for the Smith family

Step-by-step explanation:

Given.

Mr. and Mrs. Smith pay Margie $\$6.50$ an hour to babysit their son, Shea.

Mr. and Mrs. Jones pay Margie $8 an hour to babysit their children, Sarah, Susan, and Dawn.

Let x be number of hours.

Solving for Part A.

Amount of Money earn from Smith family = Pay per hour $\times$ Number of hours = $\$ 6.5 \times x= \$ 6.5x$

Solving for Part B.

x=7

Margie earns from smith family for 7 hours = $\$ 6.5x=\$6.5\times7=\$45.5$

Solving for part C.

Margie earned = $\$ 78$

To find number of hours

No of hour Margie has done babysitting for Smith family $x=\frac{\$78}{\$6.5}=12 \ hrs$

How to write slope-intercept form through (-1,3) and a slope of -1

oksian1 [2.3K]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = -1 and the point (-1, 3). Substitute:

$3=(-1)(-1)+b$

$3=1+b$ <em>subtract 1 from both sides</em>

$2=b\to b=2$

<h3>Answer: y = -x + 2</h3>

Suppose, to select a sample from a population of 3000 persons, the following procedure is followed. The names of the people are

Gwar [14]

Answer:

One can conclude that this sample is obtained through a simple random sampling technique.

Step-by-step explanation:

With a simple random sampling, each population participant has an equal chance of being selected. This sampling method is the best sampling technique when compared with other random sampling methods like the Stratified Random Sampling and Double-stage Random Sampling. The reason is that it gives equal chance to every sample to be chosen by eliminating sample bias.
