BEST ANSWER GETS BRAINLY (EMERGENCY)
MrRissso [65]

Answer:

Part A: 5

Part B: 2

Step-by-step explanation:

to find the mean all you have to do is add all the numbers together and then divide it by how many numbers there are in the data set

3+4+4+4+5+6+6+8=40

40÷8=5

so the mean is 5

next to find the mean of absolute deviations you need to subtract each number in the data set from the mean then divide it by how many numbers are in the data set (if you get a negative like 6-5=-1 just take away the negative sign to make it positive)

5-3=2

5-4=1

5-4=1

5-4=1

5-5=0

6-5=-1

6-5=-1

8-5=-3

2+1+1+1+0+1+1+3=10

10÷5=2

so the mean absolute deviation is 2

Solve |2x + 1| = 10
Ivan
By definition of absolute value we have two equalities:
 2x + 1 = 10
 2x + 1 = -10
 For 2x + 1 = 10:
 
2x + 1 = 10
 2x = 10-1
 2x = 9
 x = 9/2
 For 2x + 1 = -10:
 
2x + 1 = -10
 2x = -10-1
 2x = -11
 x = -11 / 2
 Answer:
 
{-11/2, 9/2}

Write an equation of the circle with center (2,-3) and radius 8.
Paul [167]

Answer:

(x-2)^2+ (y+3)^2 = 64

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2+ (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

(x-2)^2+ (y- -3)^2 = 8^2

(x-2)^2+ (y+3)^2 = 8^2

(x-2)^2+ (y+3)^2 = 64
