Write the equation of the circle graphed. The equation of a circle is
(x – h)^2 + (y – k)^2 = r^2

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

D and r =
For the circle graphed, the center is (-1,
Substitute the center and radius into the equation:
(x – D² + (y- 1)² =(
Simplify:
(x+
)2
+ y – 12 =
)2 + (y – 1)2 =

What percent of 18 is 24? and plz explain thx.

Twelve different video games showing substance use were observed and the duration times of game play (in seconds) are listed below. the design of the study justifies the assumption that the sample can be treated as a simple random sample. use the data to construct a 99% confidence interval estimate of μ, the mean duration of game play. 4028 4316 4816 4650 4036 5010 4833 4331 4307
