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

What’s a equivalent expression using prime factorization for the number 254

erik [133]

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

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

Since 2 and 127 are prime, the prime factorization of 254 is 2 × 127.

What is the surface area of a sphere with radius of 3.5? A. 12.25p B. 14p C. 24.5p D. 49p

Anuta_ua [19.1K]

S=4πr2 - this is the equation for the surface area of a sphere. We know that the radius (r) is 3.5 so here's how to solve this:

S = 4π r2
S = 4π (3.5)2
S = 4π 12.25
S = 49π

The surface area of a sphere with radius of 3.5 is 49π.
