Scott likes to run long distances. He can run 20 km in 85 minutes. He wants to know how many minutes (m) it will take him to run

52 km at the same pace.
Which proportion could Scott use to model this situation?
Please choose from one of the following options.

m/20=85/52

m/85=52/20

Solve the proportion to determine how long it will take Scott to run 52 km.

You wanna 
divide 85 and 52 
because he can run 20 KM in 85 min 
and he wants to see how long it takes him to run 52 KM
So the first one is correct

Find 10-3. Write the subtraction fact two ways.
love history [14]
This is a problem of fact families, but <em>what is fact families?</em> Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by w<span>riting the <em>subtraction fact two ways</em>. So we have:

</span><span>10-3

First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:

</span>Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ

So I want to take away 3 triangles, then by taking away 3<em> what is left? </em>Well the answer is 7:

Δ Δ Δ Δ Δ
Δ Δ 

That is, if we subtract 3 from 10 then the result is:

10-3=7

Second way. In this subtraction we take the same 10 triangles:

Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ

Now I want to take away 7 triangles, then by taking away 7 what is left is 3:

Δ Δ Δ

That is, if we subtract 7 from 10 then the result is:

10-7=3

Sharon wants to estimate the percentage of parents that use cloth diapers. She asks a randomly selected group of 75 parents whet
Sloan [31]

Answer: Parents.

Step-by-step explanation:

  • In statistics , a population is a large group of similar things or members by researcher's perspective from that he/ she draw a finite subset also known as sample to follow his / her research.

Here, Sharon wants to estimate the percentage of parents that use cloth diapers.

i.e.Researcher = Sharon

Since Sharon will reach parents about her objective of whether they use cloth diapers.

So , Population = Parents

If She asks a randomly selected group of 75 parents whether or not they use cloth diapers , then Sample size is 75 .

Therefore, the population is : "Parents."

Maria records random speeds from three different Internet providers in the table. Provider Download Speed (megabits per second)
Igoryamba

Answer:

<em>Able Cable </em>

Step-by-step explanation:

<u>Mean Value of Samples</u>

It's central tendency statistics measure that gives one representative value out of a complete dataset. It can be computed as the sum of the values by the number of values:

\displaystyle \bar x=\frac{\sum x_i}{n}

We need to evaluate the mean value of the three internet providers mentioned in the question.

For CityNet:

\displaystyle \bar x_1=\frac{3.6+3.7+3.7+3.6+3.9}{5}=3.7

For Able Cable:

\displaystyle \bar x_2=\frac{3.9+3.9+4.1+4.0+4.1}{5}=4.0

And for Tel-N-Net:

\displaystyle \bar x_3=\frac{3.9+3.7+4.0+3.6+3.8}{5}=3.8

We can conclude Able Cable offers the fastest mean downloading internet speed

Which graph shows the solution to the inequality Negative 3 x minus 7 less-than 20
Aleksandr-060686 [28]

Answer:

A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.

Step-by-step explanation:

we have

-3x-7

Solve for x

Adds 7 both sides

-3x

-3x

Divide by -3 both sides

Remember that

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

so

x> 27/(-3)\\x>-9

The solution is the interval (-9,∞)

therefore

A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
