The graph of the equation below is a circle. what is the length of the radius of the cirlce? (x+5)2+(y+7)2=21^2

the radii would equal 7.5

21

Step-by-step explanation:

At the end of the equation the 21 is the radius and when squared it becomes the diameter if i am correct

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

1. 22

2. 1

3. 7

4. 18
