Answer:
-7
Step-by-step explanation:
21 ÷ (4+3) - 10
=> 21 ÷ (7) - 10
=> 3 - 10

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.
<span>4 x 4 x 4 x 4 x 4 x 4 = 4^6
answer is 4^6</span>
The four brothers are each getting equal amounts of the three pizzas.
So, we should divide the amount of pizzas by the number of brothers that there are.
3/4 = .75
Therefore, each brother gets 3/4 of a pizza.
5*3 + 9 - 6/2
= (5*3) + 9 - (6/2)
= 15 + 9 - 3
= 21
