1 answer:
Answer:
Hamburger Chicken
Adults 65 60 125
children 55 20 75
120 80 200
a)What is the probability that a randomly selected individual is an adult?
Total no. of adults = 125
Total no. of people 200
The probability that a randomly selected individual is an adult =
b) What is the probability that a randomly selected individual is a child and prefers chicken?
No. of child prefers chicken = 20
The probability that a randomly selected individual is a child and prefers chicken=
c)Given the person is a child, what is the probability that this child prefers a hamburger?
No. of children prefer hamburger = 55
No. of child = 75
The probability that this child prefers a hamburger=
d) Assume we know that a person has ordered chicken, what is the probability that this individual is an adult?
No. of adults prefer chicken = 60
No. of total people like chicken = 80

If the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833
The given exponential equation is:
The function passes through the points (3, 25) and (8, 10)
Substitute x = 3 and y = 25 into the function
............................(1)
Substitute x = 8 and y = 10 into the function
.............................(2)
Divide equation (2) by equation (1)
Therefore, if the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833
