Answer:

$Mean = 7$

Step-by-step explanation:

Given

$Data: 2, 4, 6, 12, 8, 10.$

Required

Determine the mean

The mean of a data is calculated as thus:

$Mean = \frac{\sum x}{n}$

In this case:

$n = 6$

So, the formula becomes:

$Mean = \frac{2+4+6+12+8+10}{6}$

$Mean = \frac{42}{6}$

$Mean = 7$

The length of the base of a triangle is twice its height. if the area of the triangle is 44 square kilometers, find the height

xeze [42]

Let
$x$
be the height of the triangle.

Formular for area of Triangle
= ½ × base × height

thus,
${ \frac{1}{2} }(2x)(x)=44\ kilometers^2$

Simplifying
$x^2=44\ kilometers^2 \\\\ x= \sqrt{ 44 } \\\\ x=6.63\ kilometers$

What is the slope of the line that contains these points?<br> (-1,10) (0,18) (1,26) (2,34)

-BARSIC- [3]

The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) ,

(2 , 34) is 8

Step-by-step explanation:

You can find the slope of a line from any two points lie on it

The formula of the slope is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are two points lie on it

∵ A line contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34)

- To find the slope of the line chose any to points

∵ Points (0 , 18) and (1 , 26) lie on the line

∴ $x_{1}$ = 0 and $x_{2}$ = 1

∴ $y_{1}$ = 18 and $y_{2}$ = 26

- Substitute these values in the formula of the slope above

∵ $m=\frac{26-18}{1-0}$

∴ $m=\frac{8}{1}$

∴ m = 8

The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34) is 8

Madison has 64 circles and 96 squares and 48 triangles.What factors do these numbers have in common? A.1,2,4,8,or 16 B.1,2,4,6,1

cestrela7 [59]

Answer:

The correct answer is option A.

Step-by-step explanation:

Number of circles = 64

Number of square = 96

Number of triangles = 48

Factor of 64, 96 and 48;

$64=2\times 2\times 2\times 2\times 2\times 2$

$96= 2\times 2\times 2\times 2\times 2\times 3$

$48= 2\times 2\times 2\times 2\times 3$

Factors do these numbers have in common are:

64 = 2 × 2 × 2 × 2 × 2 × 2

96= 2 × 2 × 2 × 2 × 2 × 3

48= 2 × 2 × 2 × 2 × 3

Common factors = 2 × 2 × 2 × 2 =16
