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.
Answer:
d. So y = 10 (.5)^x the 10 is the initial amount of the sample at the time it was discovered
Step-by-step explanation:
When we have an equation of the form
y = ab^x
a is the initial value at time x=0
b is the growth (or decay ) factor ( 1 + or - percent)
and x is the time
So y = 10 (.5)^x the 10 is the initial amount of the sample at the time it was discovered

To find perimeter of triangles, use the formula P = a + b + c, where a, b, and c are the sides of the triangle.
For this triangle, you are given two sides and the perimeter and asked to find the third side. To do that, plug the given values into the formula for perimeter and solve.
P = a + b + c
10.8 = 3.5 + 2.6 + c
10.8 = 6.1 + c
4.7 = c
The measure of the third side of the triangle is 4.7 cm.

The perimeter of a quadrilateral is the sum of the length of its four sides. So to find the perimeter, simply add all the sides together. As you need to find a missing side, follow the same steps as above to find the missing side.
15.3 = 2.7 + 4.7 + 3.3 + x
15.3 = 10.7 + x
4.6 = x
The length of the missing side of the quadrilateral is 4.6 cm.
-3/8 -1/10 = (-15 -4)/40 = -19/40
so this mean that choice D. is right sure
hope this will help you
