What is the length of bc ? enter your answer in the box. units triangle a b c with horizontal side b c. vertex a lies above side b c. angle b and angle c are marked congruent. the length of side a c is labeled as 2 x minus 24. the length of side a b is labeled as x minus 2. the length of side b c is labeled as x.

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

Triangle ABC is an isosceles triangle

because

∠B≅∠C

therefore

AB=AC

substitute the values

Solve for x

Find the length of side BC

substitute the value of x

2 x t divided by n

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
