The segments shown below could form a triangle.

Yes, they do form a triangle, So, its true

Step-by-step explanation:

False

Step-by-step explanation:

It is false because if we use B as a base which the length of is 15, we need to have at least 15 or more to form a triangle with the other segments. But, segment A and C together is only 13 which is less than 15. So, therefore, the statement is false.

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
