Answer:

A. $0.5

Step-by-step explanation:

In this question half of the time your winning is 2 dollars and also the other half of the time your loss is one dollar

The expectation is that after you must have had 2 rolls you would get 2 dollars once and also you are going to lose 1 dollar once. So what you won overall would be 1 dollar.

So the correct answer would be gotten from $1/2rolls

= $0.50

So prime factorization is what it seems, <u>finding the prime factors of a number.</u> Using prime factorization, we can break down 254 as such:

\underbrace{254}_{\boxed{2*127}}

Since 2 and 127 are prime,<u> the prime factorization of 254 is 2 × 127.</u>

Ludmilka [50]

Answer:

Billy is incorrect. The ratio of the number of apples to the number of peppers is 3:1

Step-by-step explanation:

See the attached figure to better understand the problem

Let

x ----> the number of apples

y ----> the number of peppers

we have

x=3\ apples

y=1\ peppers

The ratio of the number of apples to the number of peppers is equal to

\frac{x}{y}

substitute

\frac{3}{1}

therefore

Billy is incorrect. The ratio of the number of apples to the number of peppers is 3:1
