The summer monsoon rains bring 80 % of India's rainfall and are essential for the country's agriculture. Records going back more

KatRina [158]

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,

$\mu + 2\sigma = 852 + 2(82) = 1016\\\mu - 2\sigma = 852 - 2(82) = 688$

Thus, 95% of monsoon rainfall lies between 688 mm and 1016 mm.

Christie sells lemonade in her driveway she spends $20 dollars on supplies lemons sugar and cups she can make enough lemonade fo

Rasek [7]

Answer:

Profit = $ 5

Step-by-step explanation:

Money spent on supplies = $ 20

Number of cups of lemonade sold by her = 100

Selling price for 1 cup of lemonade = 1 quarter = $ 0.25

∴ Selling price for 100 cups of lemonade = $0.25\times100=25$

So, Christie can make $ 25 from 100 cups of lemonade.

Profit made by her = Selling price - Money spent on supplied

= $ 25 - $ 20 = $ 5.

Find the slope of the line passing through the points (7, -1) and (2, -8).

Ugo [173]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

We have to use the slope formula: m = slope

(x1, y1) = coordinates of the first point in the line

(x2, y2) = coordinates of the second point in the line

Here, we'll plug into our given points to give; $\frac{7--1}{2--8}$

Solving this, we get, $\frac{8}{10}$ , but we're not done, as this fraction can be reduced.

Diving both sides of the fraction by 2, we get our final answer of $\frac{4}{5}$ .
