500 people took the survey.
12 out of 15 people is 80% of the population. 12/15 = 0.80
Thus, 80% of the population prefers eating in the restaurant.
If 400 represents the people who prefers eating in the restaurant; then, 400 is the 80% of the population. To get the total population or 100%, we must divide 400 by 0.80 or 80%
400 / 0.80 = 500 people.
Out of the 500 people, 400 selected eating in the restaurant while the remaining 20% of the population or 100 people selected cooking at home.
Answer:
The one with the better deal would be 30 ride tickets for $22.50 this is because you pay less money for more rides.
Step-by-step explanation:
First you divide 20 by 14. Doing this will give you the cost of a ride per ticket.
20/14 = 1.42
Then you do the same thing to 30 and 22.50.
30/22.50 = 1.30
Last you compare which deal has less money per ride.
1.42 > 1.30
Yes, since 50 x 10 = 500.
For this case we have two options:
Option A:
Tomato juice, 48 oz. can for $ 2.49.
The unit price is:
(2.49) / (48) = 0.05 cents per oz.
Option B:
Tomato juice, 6-pack of 10 oz. cans for $ 3.99.
The unit price is:
(3.99) / (6 * 10) = 0.07 cents per oz.
Answer:
The best buy would be:
Tomato juice, 48 oz. can for $ 2.49.
What is the third quartile of the following data set<br><br>
24,20,35,39,28,42,25,29,44,21,37

First, arrange the data:
20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44
You can use the formula 3/4 multiplied by the number of data + 1 to find the position of the 3rd quartile.
so it's going to be 3/4 x (11+1) = 9th position
the number in 9th position is 39 so that's the 3rd quartile
