a) 
b) 
c) 
d) 
Step-by-step explanation:
Given:
equation of line, 
x = club-head speed (in miles per hour)
y = the distance a golf ball travels (in yards)
a)
x = 100 mph
Then the distance travelled by the ball:
(put the given value of x in the above eq.)


b)
If the observed distance in the above case comes out to be 265 yards then the residual value will be:


c)
From the calculated value when rounding it to the nearest tenth:

d)
The residual on rounding the calculated value to the nearest tenth:
