Step-by-step explanation:
Given in the question,
C(8,2)
Formula to use:
nCr = n! / r! * (n - r)!
here n = 8
r = 2
We have to calculate combinations of 8 object taken 2 at a time, then
C(8,2)
8C2
8! / 2! * (8 - 2)!
56/2
28
So, 8C2 = 28
Answer:
3 hours
Step-by-step explanation:
Number of shows : Time taken
= 4 : 2
Today, they will perform 6 shows.
Number of shows : Time taken
= 6 : x
Equate both ratios to find x
4 : 2 = 6 : x
4/2 = 6/x
Cross product
4 * x = 2 * 6
4x = 12
x = 12/4
x = 3 hours
The trainers will spend 3 hours performing shows today
Answer:
7/15
Step-by-step explanation:
Answer:
y-3=-3(x+2)
Step-by-step explanation:
Point-slope form is y-y1=m(x-x1).
So if the coordinates given are (-2,3) you substitute the y1 and x1 with those variables, along with determining the slope which is -3/1 because the line goes up towards the left rathar than the right side making it negative.
And there's your equation! Hope that helped.
