Answer:

1,816,214,400 batting orders are possible.

Step-by-step explanation:

The order is important.

Suppose we had a two player batting order.

A batting order of Jonathan Schoop and Manny Machado is a different order than Manny Machado and Jonathan Schoop. So we use the permutations formula.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!)}

A baseball coach is creating a nine-player batting order by selecting from a team of 15 players. How many different batting orders are possible?

Selection of 9 players from a set of 15 players. So

P_{15,9} = \frac{15!}{(15-9)!} = \frac{15!}{6!} = 1816214400

1,816,214,400 batting orders are possible.

ss7ja [257]

Answer:

Step-by-step explanation:

2x +15 +2x +5 = 180

4x = 180 - 20

x = 160/4

x = 40

TVZ + 2x +5 =180

TVX +2(40) = 180 -5

TVX = 175 - 80

TVX = 95

If ac−b=1, which expression represents c?<br> i wil lmark you the brainliest
dolphi86 [110]

Answer:

The expression for c is

c =  \frac{b + 1}{a}

Step-by-step explanation:

The given equation is

ac - b = 1

To find an expression that represents,c we need to make c the subject.

Add b to both sides

ac = 1 + b

We now divide both sides by 'a'

\frac{ac}{a} =  \frac{b + 1}{a}

Simplify the LHS to get:

a=  \frac{b + 1}{a}
