The box plots show the average speeds, in miles per hour, for the race cars in two different races.

Murljashka [212]

Answer:

The correct option is;

The median speed in race A is about 153 miles per hour and the median speed in race B is about 145 miles per hour.

Step-by-step explanation:

Here we have the box plot which shows the following 5 values

Race A

Maximum = 170 miles per hour

Minimum = 120 miles per hour

1st quartile ≈ 142 miles per hour

Median or 2nd quartile ≈ 153 miles per hour

3rd quartile = 165 miles per hour

Race B

Maximum = 165 miles per hour

Minimum = 125 miles per hour

1st quartile ≈ 139 miles per hour

Median or 2nd quartile = 145 miles per hour

3rd quartile = 150 miles per hour

Therefore, the correct option is as follows;

The median speed in race A is about 153 miles per hour and the median speed in race B is about 145 miles per hour.

Answer:

y=4x

Step-by-step explanation:

First, find the slope

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

We know 2 points, (2,8) and (12,48).

(2,8) can be (x1, y1)

(12,48) can be (x2, y2)

We can say that y2 is 48, y1 is 8, x2 is 12, and x1 is 2. Substitute them in

$m=\frac{48-8}{12-2}$

$m=\frac{40}{10}$

m=4

Now, we can use the point slope formula, since we have a point and the slope

$y-y_{1} =m(x-x_{1})$

We know m, the slope is 4. We also know a point (2,8), which is (x1, y1). Substitute them in

y-8=4(x-2)

Distribute the 4

y-8=4*x-2*4

y-8=4x-8

Add 8 to both sides

y=4x

A dance instructor charges each student $57 for dance lessons. Students who register early receive a $15 discount. A total of 11

zubka84 [21]

Answer:

552$

Step-by-step explanation:

57 x 11= 627(you want to figure out what the instructor should be making)

Multiply 5 x 15= 75 (to figure out the amount of money lost due to discount)

Subtract 627- 75 (to get your total answer for earnings from the 11 students.)
