The owners of a sports stadium wanted to predict what additional refreshment options would sell well. They selected 50 seat numbers at random and surveyed the occupants of those seats. Identify the population and sample in this setting.

1: The population is occupants of all seats in the sports stadium: the sample is the occupants of the 50 seats.

2: The population is the occupants of the 50 seats: the sample is the refreshment options.

3: The population is all people who buy refreshments in the sports stadium: the sample is the occupants of the 50 seats.

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

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
