Asher has about a probability of winning then Ethan has which could be the outcome that Ashlee needs to win the game select thre

mash [69]

Answer:

There are 36 total possible outcomes.

Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.

Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.

Rolling a sum of 9, there are 4 possibilities, which is a better chance.

Rolling a sum less than 5, there is 6 possibilities, which is a better chance.

Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.

Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.

Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

The answers would be:

Rolling a sum of 9,

Rolling a sum less than 5

Rolling greater than 5 but less than 7

Let u= ln x and v=ln y. Write ln(x^3y^2) in terms of u and v.

amid [387]

<h2>Answer:</h2>

a. 3u + 2v

<h2>Step-by-step explanation:</h2>

To solve this problem, we need to apply some properties of logarithms. Properties are useful to simplify complicated expressions. Here we need to use a very useful property of logarithms called <em>the logarithm of a product is the sum of the logarithms, </em>that is:

$log_{b}(MN)=log_{b}(M)+log_{b}(N)$

From the function, it is then true that:

$ln(x^{3}y^{2})=ln(x^{3})+ln(y^{2})$

The other property we must use is Logarithm of a Power:

$log_{b}M^{n}=nlog_{b}M$

Then:

$ln(x^{3}y^{2})=ln(x^{3})+ln(y^{2}) \\ \\ ln(x^{3}y^{2})=3ln(x)+2ln(y)$

Since:

$u=ln(x) \\ v=ln(y)$

Then:

$ln(x^{3}y^{2})=3u+2v$

Finally, the correct option is:

a. 3u + 2v
