gizmo_the_mogwai [7]

Answer:

990

Step-by-step explanation:

The center position can be selected in 3 different ways, the other 4 players can be selected in combinations of 11 players (the center is already selected) taken 4 at a time.

By the Fundamental Principle of Counting, there are

3\displaystyle\binom{11}{4}=3*\displaystyle\frac{11!}{4!(11-4)!}=3*\displaystyle\frac{11!}{4!7!}=990

ways for her to select the starting line-up.

3x+2y=4<br> 8x-3y=-6 solving systems of equations by substitution
Over [174]

Answer:

x=0, y=2. (0, 2).

Step-by-step explanation:

3x+2y=4

8x-3y=-6

---------------

3(3x+2y)=3(4)

2(8x-3y)=2(-6)

-----------------------

9x+6y=12

16x-6y=-12

----------------

25x=0

x=0/25

x=0

3(0)+2y=4

0+2y=4

2y=4-0

2y=4

y=4/2

y=2

Write down the nth term of the sequence 5, 8, 13, 20, 29
amid [387]
Hello! To find any number in the arithmetic sequence we can use a formula!

It is given by  a_n =a_1+(n-1)d


The geometric sequence formula goes by S_n =  \frac{a_1(1-r^n)}{1-r}

So for this we notice that there's a start of 5 and is being added 3 to get 8.

and then each time it is added by 2 more to get the next time

5
5+ 3 = 8
8 + 5 = 13
13 + 7 = 20
20 + 9 = 29
29 + 11 = 41
41 + 13 = 54
54 + 15 = 69 
69 + 17 = 83

Your formula is a_n = (n-1)^2 + 4&#10;&#10;
Where n starts at 2 not 1
