Answer: See explanation

Step-by-step explanation:

1. Step 1: Add up all the numbers.

12 + 15 + 10 + 15 + 11 + 12 + 15 = 90

Step 2: Count how many numbers there are.

There are 7 numbers

Step 3: Divide the sum of the numbers by amount of numbers.

90 ÷ 7 = 12.85

12.85 ≈ 12.9

Mean = 12.9 in tenth place or 13 in whole place

2. The mode is the number that appears the most

15 appears 3 times.

3. 38 / +38

4. 1 week = 7 days

7 × 2 = 14

9 weeks = 9 × 7 = 63

63 × 3 = 189

189 + 14 = 203

203 miles in all

5. Area of 1st rectangle: b × h

Answers

Answer:

y=1/3x+3

Step-by-step explanation:

We can write this in a y=mx+b format.

b is the y-intercept and m is the slope.

The y-intercept is where x=0, or where the line intersects the y-axis. We can see that there is a point on the y-axis: (0,3). Therefore, the y-intercept, or b, is 3.

So far, we have y=mx+3.

Now we can find the slope with rise over run. (rise being the change in y and the run being the change in x.)

From one point to the other, it goes up 1 (the rise) and over 3 (the run).

m=rise/run=1/3.

y=1/3x+3.

Hope this helped.
