Mean is the average. Add the numbers together and divide the the quantity of numbers.
5 + 11 + 14 + 10 + 8 + 6 = 54
54 / 6 = 9
Mean = 9
Answer:
2400 pages
Step-by-step explanation:
Printer 1 : 50+ 1.50/30 x where x is the number of pages
Printer 2 : 10 + 2/30 x where x is the number of pages
Set them equal
50+ 1.50/30 x = 10 + 2/30 x
50 + 1/20x = 10 +1/15 x
Subtract 1/20x from each side
50 + 1/20x -1/20x= 10 +1/15 x-1/20x
50 = 10 +1/15x - 1/20x
Subtract 10 from each side
40 = 1/15x - 1/20x
Get a common denominator
40 = 4/60x - 3/60x
40 =1/60x
Multiply by 60
40 *60 = 1/60x *60
2400 =x

Step-by-step explanation:
Mode refers to a value that appears most frequently in a data set.
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Median is the number that occurs in the middle of a set of observations
Arranging the numbers in ascending order : 55, 66, 82, 89, 90, 92
median = (82 + 89) / 2 = 85.5
There is no mode because the numbers only appear once
Range = 92 - 55 = 37
mean = 476/6 = 79
