Taylor, Moore, and Jenkins are candidates for public office. It is estimated that Moore and Jenkins have about the same probabil
katrin [286]

Answer:

Taylor = 50%

Moore = 25%

Jenkins = 25%

Step-by-step explanation:

Assuming there are no other candidates and that someone has to win the election, the probabilities of Taylor, Moore, and Jenkins winning the election must add up to 1 or 100%.

T+M+J = 1\\

Since Moore and Jenkins have about the same probability of winning, and Taylor is believed to be twice as likely to win as either of the others:

M=J\\T=2J\\J+J+2J=1\\J=0.25\\M=J=0.25\\T=2*0.25=0.5

Taylor has a probability of 50% of winning the election.

Moore has a probability of 25% of winning the election.

Jenkins has a probability of 25% of winning the election.

Solve for x algebra help
mafiozo [28]

Answer:

x=24

Step-by-step explanation:

Hi there!

We are given the following proportion:

\frac{2}{10}=\frac{3}{x-9}

And we want to solve for x.

First, let's reduce \frac{2}{10}, as reducing fractions typically makes the process easier

\frac{2}{10} is the same as \frac{1}{5}

So:

\frac{1}{5}=\frac{3}{x-9}

We can't do anything to \frac{3}{x-9}, but that's okay.

Now we can cross multiply, as this is a proportion

Multiply x-9 by 1 and 3 by 5

1(x-9)=3(5)

Multiply

x-9=15

Now this is an equation

Our goal is to isolate x on one side

So let's add 9 to both sides to remove it from the left side

x-9=15

 +9 +9

_________

x=24

Hope this helps!
