Add up all the numbers together and then divide by 12 to find the average mean:-
68/12 = 17/3 or as 5 and 2/3
no 5 is not a composite number 10 15 20 and 25 are composite
The first four multiples of five: 5, 10, 15, 20
The GCF is 5.
Write the multiples of each: 5, 10, 15, 20 10, 20, 30, 40 10 is in each, so it is the answer.
5 and 10 10 and 15 15 and 20
A mean is an average An example 10 +20 +30 =60 The mean/average of this is 20
Assuming mean average: average = sum/number_of_items → 10 = sum/2 → sum = 10 x 2 = 20 So any two numbers with a sum of 10 have a mean average of 10, eg {5, 15}, {1, 19}, {0, 20}, {-5, 25}, etc. With the median average, for two numbers it is exactly the same as the mean average, so any pair of numbers that sum to 20 will do. With the mode average, only the case of the pair of numbers {10, 10} will suffice.

The mean is 15.
The average. The mean is the same as the average. For example: the mean of 4,6,10,20 is 10. 4+6+10+20=40/4=10
You cannot. It should be their weighted average with the weights representing the number of observations in each average.For example, if 3 numbers have an average of 10 and 6 numbers have an average of 20, the combined average is not the average of 10 and 20 (which is 15).It is, in fact, (3*10 + 6*20)/(3 + 6) = (30+120)/9 = 150/9 = 16.66...You cannot.

$200-$300 20*10 = 200 20*15 = 300
It means the average person can see clearly at 20 feet what you can see clearly at 15 feet.
-5 It is 15 more than -20 and 15 less than 10 To find a halfway point (which is also the average), add the numbers together and divide by 2. -20 + 10 = -10 and -10/2 = -5
