A. His answer is incorrect. 2 cubed is 2 X 2 X 2, which is 8. Add 4 and you have the answer of 12.
B. He may have multiplied 2 X 3 and then added 4, instead of multiplying 2 three times.

Answer:</h3>
D. 1/24
<h3>
Step-by-step explanation:</h3>
Assuming the die is fair and the events are independent, the probability of the series of events is the product of the probabilities of the individual events.
p(even) = 3/6 = 1/2
p(odd) = 3/6 = 1/2
p(5) = 1/6
Then the joint probability is ...
.. (1/2)·(1/2)·(1/6) = 1/24
Here, number of bulletin board = 1
Artwork = 2/5 th, & math papers = 1/5
So, it would be: 1/5 + 2/5 = 3/5
In short, Your Answer would be 3/5 or 0.60
Hope this helps!
Answer:
21x - 42, see below :)
Step-by-step explanation:
Hello!
We know that f(x) is equal to 3x - 6
We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6
7 * f(x)
7(3x-6)
We use distributive property to open the parenthesis:
7 * 3x + 7 * -6
21x - 42
