That will be 29.5
Hopefully it’s right
Slope is the rise/run.
5/20 is the slope but simplify it so it’s now 1/4
Square root of 100 = 10 cm. Next, 10*2 = 20^2 = 400 ft. Next, convert cm into ft, which would make 100 into about 3.3 ft. The ratio would then be about 3/400. Does that help?
The regression equation is in the form y = mx+b where m = 938 is the slope
The slope of 938 means that each year the tuition is increasing by roughly $938.
The answer is choice C.
The advantage is that you can visibly see the difference in the data. Disadvantage of line plots would be that not as appealing.
