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.
Given:
Spoilage rate of fruits = 9% = 0.09
To find:
Amount of fruits to be order to have 100 pounds of peaches and considering the spoilage rate.
Solution:
Let the required amount of fruits you should order be x.
So, spoiled fruits = 9% of x = 0.09x
He would like to have 100 pounds of peaches to sell.
Divide both sides by 0.91.
The required amount of fruits to be order is 110 lbs. Therefore, the correct option is D.
The minimum amount of trips would be 5. This is because in one trip he can only carry 3, so you would take 5 times 3. You may think it should be 4 trips, but 12 is 1 short of 13,so you would have to make one extra trip to get all 13 bottles.
X+y=23 (x and y added equal the number of baskets made)
2x+3y=53 (since each basket is worth a certain amount of points, x and y must be multiplied by their amount of baskets and added together to get the total number of points)
Hope this helps!
