The value of sum of the data.

The mean is calculated as,

\begin{gathered} Mean=\frac{\sum_x}{N} \\ 13=\frac{\sum_x}{7} \\ \sum_x=13\times7 \\ \sum_x=91 \end{gathered}

(2,-4) and (6,2).<br> Find the mid point
Olin [163]

Answer:

The answer is

<h2>( 4 , - 1)</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

(2,-4) and (6,2)

The midpoint is

M = ( \frac{2 + 6}{ 2}  , \:  \frac{ - 4 + 2}{2} ) \\  = ( \frac{8}{2}  \: , \:  -  \frac{2}{2} )

We have the final answer as

<h3>( 4 , - 1)</h3>

Hope this helps you

Carrie buys 4.16 pounds of apples for 5.20 how much does 1 pound cost
JulijaS [17]
4.16 / 5.20 = 1 / x.....4.16 lbs to $ 5.20 = 1 lb to $x
cross multiply because this is a proportion
(4.16)(x) = (5.20)(1)
4.16x = 5.20
x = 5.20 / 4.16
x = 1.25 per lb <==
