Assuming the same rate of change continues for the following data :
| Year(X) | 2019 | 2020 | 2021 | 2022 | 2023 |
| Profit in Percentage (y) | 38 | 40 | 65 | 72 | 69 |
- A \(y=9.4 x+18940.6\)
- B \(y=9.4 x-18940.6\)
- C \(y=9.4 x+56.8\)
- D \(y=9.4 x-56.8\)
Answer & Solution
Correct Answer
(D) \(y=9.4 x-56.8\)
Step-by-step Solution
Detailed explanation
\(n=5\) \(x = \text{Year} - 2019\) Data points for \((x, y)\) are: \((0, 38), (1, 40), (2, 65), (3, 72), (4, 69)\) \(\sum x = 0+1+2+3+4 = 10\) \(\sum y = 38+40+65+72+69 = 284\)…
