Answer:You can put this solution on YOUR website!

The numbers are between +/- 2 sd s of the mean

With Chebyshev's inequality, at least 3/4 of the numbers would be between these two.

For the one with 3 standard deviations, it would be 8/9.

----------------------

For the second part, this is 3.5 sd s on either side

1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49.

----------------

The second one would be wishing 18/8 or 2.25 sd s and that fraction would be 1/(9/4)^2=1/81/16 or 16/81 or 0.1975.

Write the equation of the line with slope 8 and passes through the point ( - 9, - 7)
AleksAgata [21]

Answer:

<h2>y = 9x + 65</h2>

Step-by-step explanation:

To find the equation of the line given the slope and a point we use the formula

y -  y_{1} = m(x - x_{1})

where

m is the slope

( x1 , y1) is the point

From the question the slope is 8 and the point is ( - 9 , - 7)

Substitute the values into the above formula and solve for the equation

We have

y  + 7 = 8(x + 9) \\ y + 7 = 9x + 72 \\ y = 9x + 72 - 7

We have the final answer as

<h3>y = 9x + 65</h3>

Hope this helps you
