The mean increases by two.
15+23+24+26+27+35 = 140
140/6 = 23.3
23+24+26+27 = 100
100/4 = 25
The mean roughly increases by 2.
You can be going the speed limit, 20 mph, or you can be going 20 mph under the speed limit. Which would mean you'd be stationary or not moving.
I don't know the effect, but I can tell you the outlier, mean, and the median.
Outlier: 60
Mean: 87.8
Median: 60
Answer:
B & C
Step-by-step explanation:
A proportional relationship has a proportionality constant (constant rate of change) and and must cross through the origin (or begin at (0,0). This means it's y-intercept is 0. Each of the options is a linear function. All of the functions have a constant rate of change. Only one as b=0 or 0 as the y-intercept.
B) y=4x has a constant of 4 and passes through the origin.
C) y=7x has a constant of 7 and passes through the origin.
