Which could be the equation of the parabola? O x2 = -4y
O x2 = 4y
O y2 = 4x
O y2 = -4x4

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

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
