First let's find the GCF of 27, 36, and 72: -->Find the factors of each number: 27: 1, 3, 9, 27 36: 1, 2, 3, 4, 9, 12, 18, 36 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 -->Now look for the factors they have in common. 1, 3, and 9 -->Now see which one is the biggest number in value 9 --> So therefore, 9 is the GCF
Now let's find the LCM of 7, 4, 10, and 12 -->Start listing all the multiples of of each number 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40... 420 7: 7, 14, 21, 28, 35, 42, 49, 56, 64, 70... 420 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 120... 420 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120... 420 (sorry got bored of typing so I fast forwarded at the '...'s) --> The least number in value that they have in common is the LCM of those numbers The LCM is 420
*Just saying that took forever to do that LCM part but not way too long thank goodness :p
LCM= 420 When you list the numbers and their multiples, you keep on listing it until you get a same #. GCF= 9 The GCF is 9. Try the birthday cake method- :0
First, put all the #s together and organized on a rectangular box.
Then, see what goes into all of the #s. Write that # down on the left side of the "cake" (the box). Keep on doing it until their is no common # that goes into them both.
You then add all of the #s that are on the side of the birthday cake.
*If that is the only # that goes into the #s, it is just that #.
I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.
The answer is <span>mean = 13,027; median = 12,200; no mode </span> Let's rearrange values from the lowest to the highest: 11350, 12050, 12200, 13325, 16211
<span>The mean is the sum of all values divided by the number of values: </span>(11350 + 12050 + 12200 + 13325 + 16211)/5 ≈ 13027
The median is the middle value. If there is an odd number of data, then the median is the value in the middle. In the data set 11350, 12050, 12200, 13325, 16211, the median (the middle value) is 12200
<span>The mode is the value that occurs most frequently. Since none of the number does not occur most frequently, there is no mode. </span>
