Help please!! The dollar value of a house is a function, f(t), of the number of years, t, since the car was purchased. The function is defined by the equation
f(x)=15,000(2/3)^x. The graph f(x) is shown.
What is the y-intercept and what does it represent in context?
a.15,000; the value of the house at the time of purchase
b.15,000; the value of the house after 1 year.
c.2/3 ; the percent decrease in value of the house each year.
d.15,000; the amount the value of the house decreases each year

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
