Here is an example:
5 can only be divided evenly by 1 or 5, so it is a prime number. But 6 can be divided evenly by 1, 2, 3, and 6 so it is NOT a prime number (it is a composite number).
So 5 is a prime number.

Given the following data;
Number of games = 8
Scores = 5, 11, 9, 9, 4, 5, 6, 7
We would sum all the scores together to get a total score.
Total scores = 5 + 11 + 9 + 9 + 4 + 5 + 6 + 7 = 56
Now, to find the mean;
Mean = 56/8
Mean = 7
Answer:
7 is the mean score.
Step-by-step explanation:
Now we have to,
→ find the required mean score.
The given scores are,
→ 5, 11, 9, 9, 4, 5, 6, 7
→ Numbers = 8
Then the mean score will be,
→ (5 + 11 + 9 + 9 + 4 + 5 + 6 + 7)/8
→ 56/8 = 7
Hence, the mean score is 7.

To find the average monthly electric bill cost for the Cox family, you need to add up the costs for each month and then divide the sum by the number of months.
Here are the steps:
1. Add up the costs for each month:
- September: $87.55
- October: $97.34
- November: $100.44
- December: $156.88
The sum of these costs is $87.55 + $97.34 + $100.44 + $156.88 = $442.21.
2. Determine the number of months. In this case, there are 4 months.
3. Divide the total cost by the number of months to find the average:
Average monthly electric bill cost = $442.21 ÷ 4 = $110.55.
Therefore, the Cox family's average monthly electric bill cost is $110.55.
Answer:
Their average monthly electric bill is at 110,55

I always simplify fractions by dividing the top and bottom of the fraction by the same numbers. Choose simple numbers you can do in your head, like 2.
I know 100/2 = 50 and 150/2 = 75
so now I have the fraction 50/75
then simplify it even more. Try dividing both top and bottom by 5s.
50/5=10 and 75/5=15
so now I have the fraction 10/15
now keep dividing by 5s.
10/5=2 and 15/5=3
so 100/150 simplifies to 2/3, or in decimal form 0.6666666666 repeating
