1) rearrange the absolute value inequality l2y-9l>1
2)clear the absolute value bars
3) solve the negative case
4)solve the positive case
5) wrap up the solution

Answer:

y=4,5

Step-by-step explanation:

Anything inside an absolute value will become postive.

So, 2y-9 can be -1 because the absolute value of -1 is 1.

Knowing this,

2y-9 = 1

2y-9 = -1

2y-9=1

2y=10

y=5

and

2y-9=-1

2y=8

y=4

y=4,5

Part (a) Make a box and whisker plot

Part (b) Identify outliners. Remove them and redraw the box and whisker diagram

Part (c) How does the removal of outliners effect box and whisker plot? How does is effect the median of the set?

Answer:

Given below with explanations

Step-by-step explanation:

(a)

The data is first arranged in ascending order:

1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42

Total values = 16

Minimum value = 1

Maximum value = 42

Lower Quartile = 1/4 x 16 = 4th value = 7 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42)

Upper Quartile = 3/4 x 16 = 12th value = 16 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42)

Median = 1/2 x 16 = 8th value = 9 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42)

The Box and whisker plot is attached in the picture below:

(b)

Outliners are 38 and 42

1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23

Total values = 14

Minimum value = 1

Maximum value = 23

Lower Quartile = 1/4 x 14 = 3.5th value = 6 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23)

(5+7)/2

Upper Quartile = 3/4 x 14 = 10.5th value = 14.5 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23)

(14+15)/2

Median = 1/2 x 14 = 7th value = 9 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23)

The Box and whisker plot is attached in the picture below:

(c)

The lower and upper quartile values have changed after removing the outliners but the median remains same in this case

What is the mean (average) of 2,4,5,6,8

irina1246 [14]

Answer:

Step-by-step explanation:

In order to figure out average, we need to add up all the numbers. So adding 2, 4, 5, 6, and 8 gives us 25. We now divide that total by the total number of terms we used to reach 25. So since we had 5 numbers, we divide 25 by 5 to get an average of 5.
