Find the coordinates of the midpoint of the segment.<br> MN with endpoints M (4, 10) and N(-2,-6)
Georgia [21]

Answer:

The answer is

<h2>( 1 , 2)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M  = ( \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M (4, 10) and N(-2,-6)

The midpoint is

M = ( \frac{4 - 2}{2}  , \:  \frac{10 - 6}{2} ) \\  = ( \frac{2}{2}  \: , \:  \frac{4}{2} )

We have the final answer as

<h3>( 1 , 2)</h3>

Hope this helps you

What can you tell about two integers when their quotient is positive? negative? or zero?
Archy [21]
If the quotient is positive, we know that the two integers are either both positive or both negative.

If the quotient is negative, we know that one integer is positive and the other is negative.

If the quotient is zero, then we are dividing 0 by some non-zero integer.

serious [3.7K]

Answer:

  57.885

Step-by-step explanation:

For such calculations a probability calculator is very helpful. The one in the attachment shows the 87th percentile to be 57.885.

___

A table of the standard normal distribution will tell you the 87th percentile corresponds to a z-value of 1.12639. Then the X value is ...

  X = Zσ +μ = 1.12639(7) +50 = 57.885
