How is the interquartile range calculated? HELP WITH APEX PLEASE!
2 answers:
By definition the interquartile range or IQR is obtained when the 25th percentile or is subtracted from the 75th percentile or
.
Thus, from the above definition, the formula for IQR is:
As we can see from the provided options that the definition of IQR matches the expression provided in Option A and thus, Option A is the correct answer.

Answer:
I'll set up the problem and you can do the calculation
Step-by-step explanation:
we need to complete the squares to get the equation in the general form:
where h = the x coordinate of the center
k = the y coordinate of the center
r = the radius
so looking at
we can see that if use -1 as the constant we have
doing the same for y
we can use -2 as the constant (basically you that the s
quare of the y coefficient )
so now we have to add or subtract the constant on the RHS to see what the square of the radius is according to the general form of the equation at the top
20 +1+4=25
Take the square root and you have the radius
