In general, nCr = n! / r! (n-r)!
Here, 7C3 = 7! / 3!(7-3)!
=7 x 6 x 5 x 4 x 3 x 2 x 1 /3 x 2 x 1 ( 4 x 3 x 2 x 1)
=7x6x5x4 / 4x3x2
=7x5x6x4 / 24
=35x24 / 24
=35

i don’t understand when it is all the same number
Answer:
5 preschoolers
Step-by-step explanation:
So this question states that yesterday, 10 preschoolers chose to play with stuffed animals and 10 different preschoolers chose to so other activities.
We can assume that there were 20 preschoolers at school yesterday (10 + 10 = 20).
From this given information, we can conclude that the preschoolers who would chose to play with stuffed animals would be the same amount at the preschoolers who would chose to do other activities.
Using all of the given information, we can also find that:
10/20 or 1/2 of the preschoolers would chose to play with the stuffed animals
and
10/20 or 1/2 of the preschoolers would chose to do other activities
We are then given that there are 10 preschoolers at school today. We are asked to find out how many of the preschoolers are expected to chose to play with the stuffed animals.
Previously, we found that 1/2 of the preschoolers yesterday chose to play with the stuffed animals. We can use this to find the expected amount of preschoolers who will chose to play with the stuffed animals today.
We can do this by multiplying 1/2 with the number of preschoolers today, or 10:
10 × 1/2 = 10/2 = 5
So it is expected that 5 preschoolers would chose to play with the stuffed animals today.
I hope you find my answer to be helpful. Happy studying.

Answer:
A.) 4/25
Step-by-step explanation:
Let: g(x)= -5x^2
find: g(g(-1))
Answer:
[tex]g(g(-1))=-125[/tex]
Step-by-step explanation:
We are given the function:
[tex]g(x)=-5x^2[/tex]
And we want to find:
[tex]g(g(-1))[/tex]
First, we will evaluate the inner function. So:
[tex]g(-1)=-5(-1)^2=-5[/tex]
Therefore:
[tex]g(g(-1))=g(-5)[/tex]
Evaluate:
[tex]g(-5)=-5(-5)^2=-5(25)=-125[/tex]
Therefore:
[tex]g(g(-1))=-125[/tex]
