Answer:

5

Step-by-step explanation:

1. according to the condition

\frac{price \ radio1}{price \ radio2} =\frac{x}{y}

2. when the both prices are increased the ratio is

\frac{x+20}{y+20}=\frac{5}{2}

3. when the both prices are reduced the ratio is

\frac{x-25}{y-25} =\frac{5}{1}

4. using the equations written in steps 2&3 it is possible to make up the system of the two equations:

\left \{ {{\frac{x+20}{y+20}=\frac{5}{2}  } \atop {\frac{x-25}{y-25}= \frac{5}{1} }} \right.

where x=160; y=52.

5. ration x:y=5.

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.

julia-pushkina [17]

Answer:

Cost = y/x

The cost of a 4 pack of apple juice is $ 2.24.

We need to write an equation that relates the cost in dollars, y, to the number of apple juice cartons, x.

As 4 packs = $2.24

1 pack = 0.56

So, the equation can be :

Cost = y/x
