The price, P, of a certain stock is given by the formula P = -6t + 50 when t is the number of years since 2000. Find the price of the stock in the year 2000 and the year 2004

year 2000: P = 50

year 2004: P = 24

Step-by-step explanation:

t is the number of years since 2000, so for the year 2000, we have that t = 0.

Using this value in the equation, we find that:

P = -6 * 0 + 50 = 50

The price of the stock in year 2000 is 50.

For the year 2004, we have that t = 4, so using this value in the equation for P, we have:

P = -6 * 4 + 50 = -24 + 50 = 26

The price of the stock in year 2004 is 24.

step-by-step explanation:

mean or average is 40.6

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
