does anyone know how to do this

Answers

1. 25%

2. unsure

[tex]\frac{25}{100} +\frac{20}{100} = \frac{45}{100} or \frac{9}{20}[/tex] (this is #3)

4. [tex]\frac{25}{100} + \frac{10}{100} = \frac{35}{100} or \frac{7}{20}[/tex] (not sure if you're supposed to use a fraction, so this might be wrong)

5. unsure

1. 100% - all the other percentages and that equals 25%

2. swimming = 30%
football = 25% = 100 ppl
5% = 20 ppl
( i divided both 25 and 100 by 5 )

30% = 120 ppl
(i multiplied both 5 and 20 by 6)

120


3. football = 25% = 25/100
baseball = 20% = 20/100

25/100+20/100= 45/100 and that simplifies to 9/20

9/20


4. (from question 2)
5% = 20ppl
tennis = 10% = 40 ppl
(i multiplied the 5 and 20 by 2)

football= 100

100+40=140

140


5.
football= 100
tennis= 40

What is the equation of a line that passes through the points (0, 5) and (4, 8)? Write your answer in slope-intercept form (y = mx + b). ( help pleaseee )

Answers

This will need become a point slope form.

First we need to find slope

(Y2-Y1/X2-X1)

(8-5/4-0) = (3/4)

Slope = (3/4)

Now for the point slope equation

y - y1 = m(x-x1)

Plug in one of the points and the slope

y - (5) = 3/4(x - (0))

Let’s convert to y = mx + b formatting

y - (5) = 3/4(x - (0))

y - 5 = 3/4x - (3/4)(0)

y - 5 = 3/4x

y = 3/4x + 5

This will be your equation.

The two-dot plots below compare the forearm lengths of two groups of schoolchildren:

Based on visual inspection of the dot plots, which group appears to have the longest average forearm length?

Group B, because three children in the group have the least forearm length of 11 inches

Group A, because three children in the group have the least forearm length of 11 inches

Group A, because seven children have a forearm length longer than 12 inches

Group B, because two children have a forearm length longer than 12 inches

Answers

Answer:

Group A because seven children have forearm length longer than 12 inches

Step-by-step explanation:

We need to look at Group A and everything after 12 inches. If we look at 13 inches, there is four dots. And if we look at 14 inches, there are three dots. Add then together to get seven children's forearm lengths.

The group which appears to have the longest average forearm length is group Group A since seven children have a forearm length longer than 12 inches.

What is Dot Plot?

Dot plots are one of the form of graphing points using dots which indicates the value on a number line.

Given are two dot plots.

In both groups, there are a total of 10 children.

It is clearly seen that from group A, 3 children have a forearm length of 12 inches, 4 children have a length of 13 inches and 3 children have a length of 14 inches.

On an average, 7 children have more than 12 inches forearm length.

Similarly, for group B, only 2 children has a forearm length of more than 12 inches.

So group B has longest average forearm length.

Hence the correct option is Group A, because seven children have a forearm length longer than 12 inches.
