Find the mean of the integers
mrs_skeptik [129]

We need to find mean of given integers.

We have -16,39,-10,-16,12,31.

In order to find mean, we need to add all the given inetgers.

Therefore, putting plus sign in between integers.

-16+ 39+ (-10)+(-16)+12+31 .

We will add all positive number 39+12+31 = 82

We will add all negative numbers by negative numbers, -16-10-16 = -42.

Therefore,  -16+ 39+ (-10)+(-16)+12+31  = 82 - 42 = 40.

We have given total 6 integers.

So, in order to find the mean, we need to apply following formula

Mean = \frac{Sum \ of \ all \ number }{Total \ numbers}

We get,

Mean = 40/6 = 6.66666......

We can round it to 6.67.

Therefore, mean of the given integers = 6.67 (approximately) .

The midpoint M of CD has coordinates (2, 5). Point C has coordinates (4, 3). What are the coordinates of point D?
AlekseyPX

The coordinates of point D is (0, 7)

<h3><u>solution:</u></h3>

The midpoint M of CD has coordinates (2, 5)

Point C has coordinates (4, 3)

To find: coordinates of point D

The midpoint of line AB conatining points (x_1, y_1) and (x_2, y_2) is given as:

\text {midpoint}(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)

Here in this problem,

Midpoint (C, D) = (2, 5)

point C (x_1, y_1) = (4, 3)

\text {point } D\left(x_{2}, y_{2}\right)=?

Subsituting the values in formula we get,

(2,5)=\left(\frac{4+x_{2}}{2}, \frac{3+y_{2}}{2}\right)

On comparing both the sides we get,

2=\frac{4+x_{2}}{2} \text { and } 5=\frac{3+y_{2}}{2}

\begin{array}{l}{4=4+x_{2} \text { and } 10=3+y_{2}} \\\\ {\text {Therefore } x_{2}=0 \text { and } y_{2}=7}\end{array}

Thus the coordinates of point D is (0, 7)
