Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home
jek_recluse [69]

Answer:

120 home runs.

Step-by-step explanation:

Let x be the number of home runs after playing 1272 games.

We have been given that Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home runs.

Let us find the probability of hitting home runs in next game.

\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{ Total number of possible outcomes}}

\text{Probability of hitting home run in next game}=\frac{15}{159}

To find the total number of home runs Derek will hit in his career, we will use relative probability, which is the ratio of the occurrence of a singular event and the total number of outcomes.

So we can set a proportion as:

\frac{x}{1272}=\frac{15}{159}

Let us multiply both sides of our equation by 1272.

\frac{x}{1272}*1272=\frac{15}{159}*1272

x=15*8  

x=120    

Therefore, Derek Jeter will hit approximately 120 home runs in his career.

Rewrite Ohm's law, V = lR to solve for the current, l, and then use the formula to find the current when the voltage is 0.6 volt
Andreyy89

Answer:

0.05 amps.

Step-by-step explanation:

I remember this one from high school.

V=IR (V=Voltage, I=Current, and R= Resistor) *Substitue values.

I=V/R

0.6/12

Divide \frac{6}{120} = 0.05 Ampere
