Bob rolls a fair six-sided die each morning. If Bob rolls a composite number, he eats sweetened cereal. If he rolls a prime numb
hammer [34]

Bob eats a 171 days sweetened cereal and 194 days he eat unsweetened cereal.

According to the statement

we have given that the Bob rolls a composite number, he eats sweetened cereal. If he rolls a prime number, he eats unsweetened cereal.

and we have to find that the expected value of the difference between the number of days.

So, the total number of days in a year is 365 days.

Chance to get a prime number on a die = 3/6

Chance to get a prime number on a die = 1/2.

and chances to get a composite number = 2/6

chances to get a composite number = 1/3

and chances to get a 1 on a die = 1/6.

Then the expected value =

so, expected value = 365(1/6) + 365(1/3) + 365(1/2)

then after calculating

Expected value = 1+2+1

then the value become is 4

and by this way he eat 171 days sweet cereal and other days he eat unsweetened.

So, Bob eats a 171 days sweetened cereal and 194 days he eat unsweetened cereal.

Jacob invested $500 in a stock and after a year had $596. what was Jacobs rate of return?
NNADVOKAT [17]

Answer:

Jacob's rate of return is <u>19.2%</u>.

Step-by-step explanation:

Given:

Jacob invested $500 in a stock and after a year had $596.

Now, to find the rate of return.

So, we get the amount of return first:

Present value - value before a year = Return.

$596 - $500 = $96.

Now, to get the rate:

Return / Value before a year × 100.

=\frac{96}{500}\times 100

=\frac{9600}{500}

=\ 19.2\%.

Therefore, Jacob's rate of return is 19.2%.
