Please answer it bro

A. 7, 5

F. 2

C. 38

Step-by-step explanation:

First and third quartiles of data - the medians of the lower and upper half of the data.

5, 7, 7, 6, 4, 8, 17, 5, 7, 5, 6, 5

In order to find the median, we must first put them in order from least to greatest.

Like this,

4, 5, 5, 5, 5, 6, 6, 7, 7, 7, 8, 17

The median is the "middle" value.

The lower half of the data set is:

4, 5, 5, 5, 5, 6

Here, there are TWO medians: 5,5

Whenever we have two medians, we must first add the medians, then divide the sum by 2.

5 + 5 = 10

10/2 = 5.

Therefore, the median of the lower half is 5.

Now, to find the median of the upper half, simply repeat these steps.

The interquartile range is the difference between the medians of the upper half and lower half.

The median of the lower half is 5.

The median of the upper half is 7.

Upper half - lower half

7 - 5 = 2

Therefore, 2 is the interquartile range.

To find the median of the shoe prices, we must first put them in order from least to greatest:

Like this,

25, 26, 27, 28, 29, 34, 35, 35, 37, 39, 40, 43, 43, 43, 45, 47, 50, 51.

The median here is 38.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol
