Find the mean of all values ... use it to work out distances ... then find the mean of those distances!
In three steps:
1. Find the mean of all values
2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)
3. Then find the mean of those distances
Answer:
Step-by-step explanation:
First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is .
Answer:
Step-by-step explanation:
equation of a circle: (x – h)^2 + (y – k)^2 = r^2 where (h,k) is the center
The center of the circle is at (5, -3)
(x-5)^2+(y+3)^2
To find the radius, use distance formula:
<h3>We look for the one with the least coefficient of x²:</h3>
<h2>Answer:</h2><h3>y=1/8 x²</h3>
