Answer:
The total cost is represented by
Step-by-step explanation:
We have been given-
Calvin paid $1.79 per pound of beans both times that he went shopping. This is a constant value.
He bought 4.05 pounds of beans the first time and 2.78 pounds the second time.
So, the total cost in dollars of the beans he bought is represented by:
This is because the standard rate is $1.79 per pound.
No mater how many pounds you buy, you will have to multiply that with standard rate of $1.79.

Question:
A = {2, 3, 4, 5}
B = {4, 5, 6, 7, 8}
Two integers will be randomly selected from the sets above, one integer from set A and one integer from set B. What is the probability that the sum of the two integers will equal 9?
A. 0.15
B. 0.20
C. 0.25
D. 0.30
E. 0.33
Answer:
Option B: 0.20 is the probability of the sum of the two integers.
Explanation:
The sample space for selecting 2 numbers is given by
We need to determine the probability that the sum of two integers will be equal to 9.
Hence, we need to add the two integers from the sets A and B such that their sum will be equal to 9.
Hence, the sets are
Thus, the total number of sets whose sum is equal to 9 = 4
The probability that the sum of the two integers will equal 9 is given by
Thus, the probability that the sum of the two integers will equal 9 is 0.20
Hence, Option B is the correct answer.
