Answer:
0.001709
Step-by-step explanation:
The probability of getting 9 tails then 1 head is:
(½)⁹ (½)¹ = (½)¹⁰
The probability of getting 10 tails then 1 head is:
(½)¹⁰ (½)¹ = (½)¹¹
The probability of getting 11 tails then 1 head is:
(½)¹¹ (½)¹ = (½)¹²
The total probability is:
(½)¹⁰ + (½)¹¹ + (½)¹²
0.001709
gives an average cost per unit, if we want to produce x of them.
So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500).
So to calculate the cost of one unit when producing 1250, we calculate C(1250)

$ is the cost of 1 toy car.

Answer:
Chris earned $ 43,344 each year
Monthly Chris earns $ 3,612
Step-by-step explanation:
If you earn a fixed amount of money each month, for 2 years and one year you have 12 months, then 2 years equals 24 months.
To know how much you earn each month we divide the total amount earned in the two years between 24 months
I = $ 86,688 / 24
I = $ 3,612
Monthly Chris earns $ 3,612
To calculate what he earned each year we divided $ 86,688 / 2
I = $ 86,688 / 2
I = $ 43,344
Chris earned $ 43,344 each year
