miskamm [114]3 years ago
8 0

Answer:

By IQR , i hope you meant inter quartile range

Steps:

Step 1: Put the numbers in order.

            2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7

Step 2: Find the median.

               2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7

Step 3: Place parentheses around the numbers above and below the median. (it makes Q1 and Q3 easier to spot.)

             (2, 3, 3, 4, 4,) 4, (4, 5, 5, 6, 7)

Step 4: Find Q1 and Q3

Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.

            (2, 3, 3, 4, 4,) 4, (4, 5, 5, 6, 7)\\\\Q_{1} = 3 \ and \ Q_{3}= 5

Step 5: Subtract Q1 from Q3 to find the interquartile range.    

               IQR =Q_{3}-Q_{1} =5-3=2

The equation formula of the circle is (x-h)^2 + (y-k)^2 = r^2
where (h,k) the point of the  center of the circle
and (r) is the radius of the circle 
so if the center of the circle = (-2,-4)  
by subs. in the formula we get (x-(-2))^2 + (y-(-4))^2 = r^2 
then the equation will be (x+2)^2 + (y+4)^2 = r^2 
now we want to define the radius of the circle r
since point (3,8) lay on the circle so we can 
then subs. in the equation to get the radius 
(x+2)^2 +(y+4)^2 = r^2 
(3+2)^2 +(8+4)^2 = r^2 
25 + 144 = r^2 
r^2 = 169 
r= 13 
the radius of the circle is 13 
so by subs in the equation we get 
(x+2)^2 + (y+4)^2 = 169 
so it is the first answer in the choices
