In order to solve this problem, it is helpful to draw a diagram (see image below). Since slope is “rise over run” you can make an equation of 4/x = .25 . Then by multiplying each side by x, you can get rid of the fraction. Next, you divide both sides by .25 . You will end up with x=16

The table below shows the height (in inches) and weight (in pounds)of eight basketball players.
Height=67, 69, 70, 72, 74, 78, 79 Weight=183, 201, 206, 240, 253, 255 what is the correlation of the set of data? Round your answer to the nearest thousandth.
d.0.981
3.The table below shows the average height of a species of tree (in feet) after a certain number of years.
Years=1, 2, 3, 4, 5, 6, 7, 8 Height=2.1, 3.2, 6.8, 7.3, 11.2, 12.6, 13.4, 15.9 about how tall would you expect one of these trees to be after 22 years?
c.44.25ft
4.You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.984. How confident can you be that your predicted value will be reasonably close to the actual value?
c.I can be very confident; it will be close, but it probably won't be exact.

P Q R
Distance from P to R = 120m
120 ÷ 5 = 24m
The distance from Q to R is 24m.
