Triangle abc is isosceles with ac=bc.
[bc] and [ac] are produced to e and d respectively so that ce= cd.
prove that ae=bd

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

answer: options

step-by-step explanation:

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
