3. kim ran 3 one-mile races, 6 two-mile races, 4 five-mile races, and 1 ten-mile race. what is the mean number of miles kim ran in the races? show your work.

3.2 miles

Step-by-step explanation:

The "mean" of a set of numbers is the average. To get this, you add up all of the numbers and then divide by however many there are. So, let's lay out the races that Kim ran.

1, 1, 1, 2, 2, 2, 2, 2, 2, 5, 5, 5, 5, 10

These numbers add up to 45 total miles ran. You can add them up individually or make an equation.

x = (3 × 1) + (6 × 2) + (4 × 5) + (1 × 10)

x = 3 + 12 + 20 + 10

x = 15 + 30

x = 45

Now, divide by the total number of races, 3 + 6 + 4 + 1 = 14

So, the mean will be

45 ÷ 14 = 3.21 or about 3.2

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
