I need help! Please explain if you can!
I need to find the csc A, sec A, and cot A.

Step-by-step explanation:

the length of AB = √10²+7²=√149

so,

csc A = AB/BC = √149/ 7

sec A = AB/AC = √149/ 10

cot A = AC/BC = 10/7

a² + b²= c²

24² + 7² = c²

c= 25

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
