I would say C since a and d don't match, so either c or d
Answer:
95% of monsoon rainfall lies between 688 mm and 1016 mm.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 852 mm
Standard Deviation, σ = 82 mm
We are given that the distribution of monsoon rainfall is a bell shaped distribution that is a normal distribution.
68 ‑ 95 ‑ 99.7 rule
- Also known as Empirical rule.
- It states that all data lies within the three standard deviation of the mean for a normal distribution.
- About 68% of data lies within one standard deviation of mean
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.
We have to find the monsoon rains fall in the middle 95 % of all years.
By the rule 95% of data lies within two standard deviation of mean.Thus,
Thus, 95% of monsoon rainfall lies between 688 mm and 1016 mm.

Step-by-step explanation:
7x² + 6x + 9x² - 5x
49x + 6x + 81x - 5x
136x - 5x
