Answer:

8.66666666667

Step-by-step explanation:

Step 1:

3/5 ( r - 7 ) = 1 Equation

Step 2:

3/5r - 4.2 = 1 Multiply

Step 3:

0.6r = 5.2 Add 4.2 on both sides

Step 4:

5.2 ÷ 0.6 Divide

Answer:

r = 8.66666666667

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.

Find the explicit formula for the geometric sequence cn given below. Note that c1=6.

kodGreya [7K]

The explicit formula for the geometric sequence $c_{n}$ is

$c_{n}=6(\frac{-1}{3})^{n-1}$

Step-by-step explanation:

The formula of the nth term of a geometric sequence is

$a_{n}=a(r)^{n-1}$ , where:

a is the first term of the sequence
r is the common ratio between the consecutive terms

The geometric sequence of $c_{n}$ is 6 , -2 , $\frac{2}{3}$ , $\frac{-2}{9}$ , $\frac{2}{27}$

∵ $c_{1}$ = 6

∵ $r=\frac{c_{2}}{c_{1}}$

∵ $c_{2}$ = -2

∴ $r=\frac{-2}{6}$

- Divide both term by 2 to simplify it

∴ $r=\frac{-1}{3}$

∵ $c_{n}=c_{1}(r)^{n-1}$

- Substitute the value of $c_{1}$ and r in the rule above

∴ $c_{n}=6(\frac{-1}{3})^{n-1}$

The explicit formula for the geometric sequence $c_{n}$ is

$c_{n}=6(\frac{-1}{3})^{n-1}$
