Answer: It will take him 1.68 years to recover his initial investment.
First, find the amount of extra money that he will make.
34,000 - 13,000 = 21,000
He will be making an extra 21,000 per year.
Now, divide the cost of his training by the amount of his increase.
35200 / 21000 = 1.68
That gives you the amount of years it will take him to pay off his investment.
$ 20.25 divided by 3 3/4 lbs
change 3 3/4 to a decimal = 3.75
$20.25 / 3.75 lbs
$5.40 per pound
so 1 pound of candy costs $5.40
Answer: $5.40

Step-by-step explanation:
Answer:
10
Step-by-step explanation:
It is much easier to do this for one die. There is a 1/6 chance that a 3 occurs on a six-sided die. Another way to say that is that the expected number of 3’s that occur on a roll of a six sided die is 1/6. If we let X be 1 if a 3 occurs on the roll and 0.
Now, if the die is rolled 60 times, then we have 60 different values X1, X2,…,X60
Of course, this shouldn’t be all that surprising. After all, we threw the die 60 times, and there are 6 faces, so it seems reasonable that for a fair die, each face should come up about 10 times.
