(urgent!) Given: ∆ABC – iso. ∆, m∠BAC = 120° AH ⊥ BC, HD ⊥ AC AD = a cm, HD = b cm Find: P∆ABH

no not all of them.

step-by-step explanation:

some of them have a square base.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

move it to the other side

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
