4,248 times 0.90 equals 3823.2; so 3823.2 students are enrolled.
Answer:
128 combinations
Step-by-step explanation:
We are told in the question that a frozen yogurt shop has:
8 flavors of frozen yogurt
2 kinds of syrup
8 toppings.
The combinations that can be made with one flavor of frozen yogurt, one syrup, and one topping is calculated as:
8 × 2 × 8
= 128 combinations
Therefore, the combinations that can be made with one flavor of frozen yogurt, one syrup, and one topping is 128 combinations.
Total number of marbles = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12
P(not red) = 12/20 = 3/5

Answer: 3/5
Step-by-step explanation: In your problem, we're finding the mean and median. Let's do it step-by-step.
1. To find the Median, we arrange the data in an ascending order and it's middle value. If the numbers of values is an even number (2, 4, 6, 8, 10), the median will be the average of the 2 middle numbers.
Therefore, the Median is 3.
2. The Mean is the set of numbers of the sum divided by the number of terms.
Therefore, the Mean is 2.8.
Answer:
Giant Candy Bar: 2$
Small Bags of Jawbreakers: .50$
Step-by-step explanation:
First you make out the equations, with the variables of c for giant candy bars and j for the small bags of jaw breakers.
First equation we make is 6c+2j=13
The second equation is 4c+6j=11.
You can then make one of the equations a negative and equal to the other. What I mean is we can use the elimination method. So I choose to do -18c+-6j=-39 (Multiplied by -3) so we can eliminate the 2 6js and get 4c=11 and -18c=-39. You then add the remaining equations together to get -14c=-28, so c=2. Using that we can then chose an equation to substitute c with. Ill choose the first one, so you get 6(2)+2j=13. 12+2j=13; 2j=1. By simplifying, you get the jawbreakers as .50 dollars.
