Step-by-step explanation:
A is not a statistical question because there's only a specific value of computers in the lab
B is not a statistical question because there is only one answer, which is 9 letters
C is a statistical question because members can have different favorites (or they find it hard to choose one).
D is not a statistical question because there is only one amount of people that helped out.

Answer: Are there answer options?
Step-by-step explanation:
7a + 6c + 9a - 15c
-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c
Answer:
x=-8
y=4
Step-by-step explanation:
first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16
3x+2y=-16
(x+9y=28)3 _multiply with 3
3x+2y=-16
3x+27y=84
use minus(-) =3x-3x=0
=2y-27y=-25y
=-16-84=-100
the result:-25y=-100
y=4
take any simple equation and replace y with 4
x+9y=28
x+9(4)=28
x+36=28
x=28-36
x=-8
answer:x=-8,y=4

Answer: A) 6</h3>
=====================================================
Explanation:
Plug n = 6 and r = 5 into the nCr combination formula
Or you could use the shortcut
Yet another path you could take is to use Pascal's Triangle. Locate the row that starts with 1,6,... and then locate the second to last item. That value in the triangle is 6.
A real world interpretation is to consider having 6 people and you are selecting 5 of them to form a group where order doesn't matter. How many ways are there to do this? Well there are 6 such ways because there are 6 ways to leave someone out of the group.
