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

ore than a century show that the amount of monsoon rainfall varies from year to year according to a distribution that is approximately Normal with mean 856 millimeters (mm) and standard deviation 89 mm. Use the 68-95-99.7 rule to answer the following questions.
Between what values do the monsoon rains fall in 95% of all years?

How small are the monsoon rains in the driest 2.5% of all years?

What’s the equation of the line that passes through (2,3) and is parallel to the line 12x-5y=2
TiliK225 [7]

12x-5y=2

-5y=2-12x

y=-2/5+12/5x

should know the m=12/5

and (2,3) bring them to the line equation:

3=12/5x2+b

6/5+b=3

b=3-6/5

b=9/5

y=12/5x+9/5

Which means the answer is not in the choices.

What is the distance between the points D(15,6) and E (-4, 2)? Round to
slamgirl [31]

Answer:

d= 19.4units

Step-by-step explanation:

Given coordinates:

     D(15,6) and E (-4, 2);

Unknown:

Distance between the two points  = ?

Solution:

To solve this problem, the distance between two points can be found using the expression below:

   d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1} ) ^{2}   }

x₁ = 15

x₂ = -4

y₁ = 6

y₂ = 2

 Insert the parameters and solve;

    d = \sqrt{[(-4 -15)]^{2} + [(2 -6)]^{2}  }

    d  = \sqrt{(-19)^{2} + (-4)^{2}  }

    d = \sqrt{361 + 16}  

    d = \sqrt{377}

    d= 19.4units
