Equation of a Circle:

A circle is defined as a shape where all the points on the circumference have the same distance r to a given point (h,k) called the center.

The equation of such a circle is given by

We are given the graph of a circle where we can clearly note the center is located in (-6,4). The radius is best obtained by looking at the center and the y-intercept at the point (0,4). The distance between them is the radius r=6

The equation of the circle is:

Or, equivalently

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
