The population of detroit, michigan has declined 20% every decade since 1950. In 2010, there was a population of 713,000. Please help with the following questions:
-Does this situation describe growth or decay? a. Growth b. Decay
-What is the rate of this growth or decay? a. 2 b. 0.80 c. 0.20 d. 0.02
-Write an equation to represent the situation. a. y= 713000(0.20)x b. y = 713000(1+0.2)x c. y = 713000(20)x d. y = 713000(1 -0.2)x
-If the trend continues, what will the population be in 2040? (Hint: how many DECADES is this?) a. 883 b. 142,600 c. 365,056 d. 570,400
- What was the population in 1990? (Hint: how many decades AGO was this?)
a.61,842,892 b.1,114,063 c.570,400 d.285,200

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

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

answer: 8d
