The chorus has 30 members. what expression represents the number of ways a group of 6 members can be chosen to do a special performance?

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
