Answer:
Simple random sampling method is used here.
Step-by-step explanation:
Given is that the evening host of a dinner dance reached into a bowl, mixed all the tickets around, and selected the ticket to award the grand door prize.
We can see that this is a simple random sampling method as every name on the ticket has an equal opportunity to get selected.
To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:
let x cost of small pizzas
y cost of soda
z cost of salad
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14
one small pizza, a liter of soda, and three salads cost $15
x + y + 3z = 15
three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22
Solving for x, y and z, we will have:
x = $ 5
y = $ 1
z = $ 3
4 )16= 4 DIVIDE 16 BY 4 TO GET 4 EVEN GROUPS OF 4 TEAMS
