What is the mean of 70 70 72 68 68 66?
43
What is the median in 70 68 72 65 70?
Median is 70 The median is the middle number once you have reordered the sequence (therefore, 72 is not the median). The mode is the most common number The mean is the average.
He lost one paper score but he knows the four scores are 65 and 62 and 70 and 68 and the average is 66 decmail 2 but what is the missing score?
(s + 65 + 62 + 70 + 68) / 5 = 66.2 ∴ s + 65 + 62 + 70 + 68 = 331 ∴ s = 331 - 65 - 62 - 70 - 68 ∴ s = 66
What is the pecentage of 70 out of 72?
Work it out: divide 70 by 72, then multiply by 100. (70/72)*100 = 97.222...%
What is the median of 71 plus 67 plus 67 plus 72 plus 76 plus 73 plus 68 plus 72 plus 72?
I guess you mean: What is the median of the numbers 71, 67, 67, 72, 76, 73, 68, 72, 72? (because adding the numbers would yield a single number). The median is the middle number when the numbers are listed in order. Listing in order: 71, 67, 67, 72, 76, 73, 68, 72, 72 ⇒ 67, 67, 68, 71, 72, 72, 72, 73, 76 There are 9 numbers, so the middle number is the 5th one which is 72. If there had been an even number of numbers, there is no middle one so the median is the mean average of the middle two. Example: If there had been no 76, so the list contained: 67, 67, 68, 71, 72, 72, 72, 73 then there would be 8 numbers, so the median would be the mean average of the 4th and 5th numbers, namely: (71 + 72) ÷ 2 = 71.5
