Look at the dot plot to answer the following question. how many more people started babysitting when they were 13 rather than 12? a. 3 b. 6 c. 12 d. 13

There are 3 more dots above the 13 than are above the 12, so the appropriate choice is ...

... A. 3

Option A is correct.

Step-by-step explanation:

Given: A Dot Plot

We need to find Number of more people who started babysitting when they were 13 rather than 12.

Number of people who started baby sitting when they were 12 year old = 3

Number of people who started baby sitting when they were 13 year old = 6

Number of more people who started babysitting when they were 13 rather than 12 = 6 - 3 = 3

Therefore, Option A is correct.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
