Answer:

Mean= Summation /number of terms

= 48/8

=6.

Median

To do this

arrange all terms from smallest to biggest

That is

2,4,4,5,7,8,9,9

The two middle numbers are

5 and 7.

To get the median

add both and divide by 2

5+7 = 12... 12/2 =6

Median=6

Mode.... This is the number that appears most

Mode = 4 and 9.(Bimodal) Both appear equally.

Range: Highest - Lowest

= 9-2 =7.

n=6

second polygon

n=2(6)=12

ext. ang= 360°/n = 360°/12° = 30°

int. ang = 180°-30°= 150°

Solve the systems of equations y=2x and y=-x - 6

slava [35]

Answer:

y = -4

x = -2

Step-by-step explanation:

Hi there...

y = 2x

y = -x - 6

Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...

2x = -x - 6

add x on both sides...

3x = -6

divide by 3 on both sides...

x = -2

Now, plug in x for y. Here's what I mean...

y = 2x

y = 2 (-2)

y = -4

Hope this helps :)
