Answer:
(a) 81 items
(b) 104 items
(c) 155 items
Step-by-step explanation:
Given:
The expression for the number of items produced by a new employee daily after 't' days on the job is given as:

(a) Number of days (t) = 5
Average number of items produced can be obtained by plugging in 5 for 't' in the above expression. This gives,

Therefore, nearly 81 items are produced after 5 days.
(b) Number of days (t) = 9
Average number of items produced can be obtained by plugging in 9 for 't' in the above expression. This gives,

Therefore, nearly 104 items are produced after 9 days.
(c) Number of days (t) = 30
Average number of items produced can be obtained by plugging in 30 for 't' in the above expression. This gives,

Therefore, nearly 155 items are produced after 30 days.
Put all of the numbers you have (starting from the smallest number to the biggest) in a line. Then the number in the middle is the median.
-81=3(5-4r)
27=-(5-4r)
27=-5+4r
-4r=-5-27
-4r=-32
r=8
Hope my answer helped u :)
Move all the terms that don't contain m to the right and solve.
The answer is m=-1
It would be something along the lines of y = p2.75 or p times 2.75
