Answer:
If they buy 6 cheese pizzas, they buy 2 pepperoni pizzas.
For every 3 cheese pizzas, they bought 1 pepperoni pizza.
If they buy 6 cheese pizzas:
3 * ? = 6
Rearrange to find ?
6 / 3 = ? = 2
You multiply both sides by the same number.
1 * 2 = 2
If they buy 6 cheese pizzas, they buy 2 pepperoni pizzas.

Answer:B
Step-by-step explanation:
B
In order for S(t) to equal to 0, it would take 9 years. If you multiply 9 times the -120, you will get -1080, then you add that to the +1,080 and the answer is 0.
<em>Y</em>₁ and <em>Y</em>₂ are independent, so their joint density is

By definition of conditional probability,
P(<em>Y</em>₁ > <em>Y</em>₂ | <em>Y</em>₁ < 2 <em>Y</em>₂) = P((<em>Y</em>₁ > <em>Y</em>₂) and (<em>Y</em>₁ < 2 <em>Y</em>₂)) / P(<em>Y</em>₁ < 2 <em>Y</em>₂)
Use the joint density to compute the component probabilities:
• numerator:






• denominator:

(I leave the details of the second integral to you)
Then you should end up with
P(<em>Y</em>₁ > <em>Y</em>₂ | <em>Y</em>₁ < 2 <em>Y</em>₂) = (1/6) / (2/3) = 1/4
