Question 12.12. In 2010, the population of a city was 65,903. It was expected to grow at a rate of 0.7% each year.
postnew [5]

y=Ce^{kx}

k=0.7%=0.007

65903=Ce^{.007(0)} \\  65903=Ce^0 \\  65903=C(1) \\ C = 65903

y=65903e^{0.007(2027-2010)}\\y=65903e^0.229 \\ y = 74231.157

A cargo van is carrying 20 identical steel cylinders.Each cylinder contains compressed oxygen.Altogether,the cylinders weigh 1/2
sergeinik [125]
Each container is 50 pounds, forget about the second sentence it's just there to confuse you. One ton is 2,000 pounds, half of that is 1,000 lbs. 1,000 divided by 20 is 50. 50 pounds each.

In a lottery game, a single ball is drawn at random from a container that contains 25 identical balls numbered from 1 through 25
Solnce55 [7]

Answer:

17/25

Step-by-step explanation:

The equation for the probability of two events that are not mutually exclusive is:

p(A ∨ B) = p(A) + p(B) - p(A ∧ B)

A = the number is prime

B = the number is prime

The numbers are:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25

Here are the 8 prime numbers that satisfy event A:

3, 5, 7, 11, 13, 17, 19, 23

p(A) = 8/25

Here are the 13 numbers that are greater than 12 that satisfy event B:

13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25

p(B) = 13/25

Here are the 4 numbers that satisfy both event A and event B:

13, 17, 19, 23

p(A ∧ B) = 4/25

p(A ∨ B) = p(A) + p(B) - p(A ∧ B)

p(A ∨ B) = 8/25 + 13/25 - 4/25

p(A ∨ B) = 17/25
