Answer:

The Empirical Rule

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

So the answer to this question is the Empirical Rule

Find the slope between two points, (1,4) and (13,3)​
Ray Of Light [21]

Answer:

slope = - \frac{1}{12}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (13, 3)

m = \frac{3-4}{13-1} = \frac{-1}{12} = - \frac{1}{12}

A satellite is 13,200 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the sa
Fudgin [204]
There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.

AB = 13200 miles
AO = 4000 miles
OB = 4000 miles
Let us assume CB = x
Then

(x + 4000)^2 = (13200)^2 + (4000)^2
<span>x = sqrt(13200^2 + 4000^2) - 4000
   = 13793 - 4000
   = 9793 miles.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.</span>
