Answer:

1.   2

2.  6

3.  2

4.  3

5.  1

6.   1

Step-by-step explanation:

First put the data in order from smallest to largest

2,2,2,3,3,6

The minimum is 2

The maximum is 6

The median is 2,2,2    ,3,3,6  is between the 2 and 3  (2+3)/2 = 2.5

The 1st quartile is 2,2,2  is the middle number   = 2

The third quartile is   3,3,6  is the middle number is 3

The interquartile range is 3-2 =1

The mean average deviation is

First find the mean: ( 2+2+2+3+3+6)/6 =18/6 = 3

Then find how far each point is from the mean

(3-2) + (3-2) + (3-2) + (3-3) + (3-3) + (6-3)  = 6

Divide this by the number of data points

6/6 =1

Solve for x in the equation x squared + 2 x + 1 = 17.
lbvjy [14]

Answer:

Step-by-step explanation:

x^2 + 2x + 1 = 17

x^2 + 2x = 17 - 1

x^2 + 2x = 16

x^2 + 2x + 1 = 16 + 1

(x + 1)(x + 1) = 17

(x + 1)^2 = 17

x + 1 = sqrt 17

x = -1 (+ - ) sqrt 17

x = -1 + sqrt 17 or x = -1 - sqrt 17 <===
