Answer:
Option (d)
Step-by-step explanation:
From the given table,
Number of members in 1980 (t = 0) were 5400.
With the period of time number of members increased.
Let the number of years after 1980 = x
Therefore, line of best fit will be in the form of y = mx + b
Where b = Initial number of members = 5400
m = Increase in members in every 5 years duration
So the equation will be,
y = mx + 5400
From the given options,
Equation which matches to our equation is,
y = 310.58x + 5400
For the number of members in year 2022,
x = 2022 - 1980 = 42 years
y = 310.58(42) + 5400
y = 18445
Option (d) will be the answer.
