Answer:
3.16
Step-by-step explanation:
Mean:
(12+14+5+13+11)/5
11
Sum of squares:
12²+14²+5²+13²+11²
655
Variance = 655/5 - 11²
= 10
sd = sqrt(10)
3.16227766
We need to find the center and the radius of

The general circle equation is the following

where
(h,k) is the center and
r is the radius
1. rearrange the equation

2. Add 25 on both sides

3. Factor

Now we have an equation that is very similar to the circle equation, so let's compare them
Center -> (h,k) = (5,-11)
radius -> r = 5
55x=330. so x=6 the domain is 6 because its the input and 330 is the range because its the outpt
