The answer is 17 and yeah I believ
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:
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
1,816,214,400 batting orders are possible.
Answer
The answer is C
Explanation:
1.2 divided by 4 = 0.3
2.4 divided by 8 = 0.3
3.9 divided by 13 = 0.3
**hope this helps.... brainly please if possible
Answer:
A
Step-by-step explanation:
The linear equation in two variables is given to us is
→ y = 3( x -4) +6x
<u>Slope </u><u>Intercept</u><u> Form</u><u> </u><u>:</u><u>-</u><u> </u>
- The slope intercept form of the equation is y = mx + c .
→ y = 3x - 12 + 6x
→ y = 6x + 3x -12
→ y = 9x - 12

Hence the correct option is A .</h3>

The number of balls to make an equilateral triangle with the sides of length n is expressed by the formula n(n+1)/2
So to express the number of balls you have is
b = n(n+1)/2 + 4
With the larger arrangement you have
b = (n+1)(n+2)/2 - 3
Both of those qualities are equal to each other, so set an equation where they're equal. Then solve for n
n(n+1)/2 + 4 = (n+1)(n+2)/2 - 3
Distribute the n term on the left
(n^2 + n)/2 + 4 = (n+1)(n+2)/2 - 3
Distribute the /2 on the left.
0.5n^2 + 0.5n + 4 = (n+1)(n+2)/2 - 3
Multiply (n+1)(n+2) on right, then distribute the /2
0.5n^2 + 0.5n + 4 = 0.5n^2 + 1.5n + 1 - 3
Subtract 0.5n^2 + 0.5n from both sides
4 = n + 1 - 3
Add 2 to each side
6 = n
So the original triangle had sides with a length of 6, for a total number of balls of
6(6+1)/2 = 21
with 4 extra giving 25 balls. Let's check with the next larger triangle
7(7+1)/2 = 28
with 3 balls shortage. Which 25 balls would make happen.
So the number of balls in the set is 25</span>
