what is the mean for the following number? 40,60,55,45,100 ?______
what is the lest Common Multiple (LCM)for 6 and 12 ?_______
please! help me i got stuck with this today!! thank you.
The mean is the average.
40 + 60 + 55 + 45 + 100 = 300
300 / 5 = 60
The least common multiple is the smallest number that each number goes into evenly. The LCM for 6 and 12 is 12.
Ms. Sue your help is greatly appreciated . May god watching you from above the sky everywhere you go and be safe give you a blessing !!bye!!
You're welcome.
To find the mean of a set of numbers, you add up all the numbers and then divide the sum by the total number of numbers in the set. In this case, you want to find the mean of the numbers 40, 60, 55, 45, and 100.
Step 1: Add up the numbers:
40 + 60 + 55 + 45 + 100 = 300
Step 2: Divide the sum by the total number of numbers:
300 ÷ 5 = 60
Therefore, the mean of the numbers 40, 60, 55, 45, and 100 is 60.
Now, let's move on to finding the least common multiple (LCM) of 6 and 12.
To find the LCM of two numbers, you can use several methods. One common approach is to list the multiples of the two numbers until you find the first multiple that they have in common.
Step 1: List the multiples of 6:
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, ...
Step 2: List the multiples of 12:
12, 24, 36, 48, 60, 72, 84, 96, ...
The least common multiple is the smallest multiple that appears in both lists. In this case, the LCM of 6 and 12 is 12.
Therefore, the LCM of 6 and 12 is 12.
I hope this helps! Let me know if you have any further questions.
