Answer:
Step-by-step explanation:
It is given that In a survey of a town, 56% of residents own a car, that is P(A)=0.56
21% of residents now a truck, that is P(B)=0.21
and 4% of residents own both a car and a truck that is P(A∩B)=0.04
Now, the conditional probability that a person also owns a truck, given that they own car is:
Thus, the conditional probability that a person also owns a truck, given that they own car is 0.190.

Answer:
- geometric sequence with initial value 20 and common ratio 1/2
- average rate of change on [1, 3] = -7.5
Step-by-step explanation:
(a) The given points have sequential values of x and values of y that are each 1/2 the value before. The common ratio tells us the sequence is a geometric sequence.
(b) The first given point is (2, 10), so extrapolating backward, we determine the previous point to be ...
... (2-1, 10/(1/2)) = (1, 20)
Thus, we have enough information to determine the average slope between n=1 and n=3.
... (difference in y)/(difference in n) = (5 -20)/(3 -1) = -15/2 = -7.5
