65, 66 67 68 and 69 can all be numbers to be rounded to 70.

60, 62, 63, 64, 65, 66, 68, 69, 70

Between 60 and 70 the composite numbers are: 62, 63, 64, 65, 66, 68, 69. 60 and 70 are also composite.

60, 62, 63, 64, 65, 66, 68, 69, 70

65 is the median,

(s + 65 + 62 + 70 + 68) / 5 = 66.2 ∴ s + 65 + 62 + 70 + 68 = 331 ∴ s = 331 - 65 - 62 - 70 - 68 ∴ s = 66

65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80

70

All are composite except 61 and 67. Composite numbers: 60, 62, 63, 64, 65, 66, 68, 69, 70

Composite numbers less than 70 and greater than 60 are 62, 63, 64, 65, 66, 68 and 69.

50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70

Hiterby, Cybern, Fillish, and Ewern

to find the mean of a group of numbers, add them together and divide by the number of numbers there are in that group. in this case there are 6

65 and 56

step 1. arrange the numbers in ascending order (from low to high) as follows. was: 64 80 64 70 76 79 67 72 65 73 68 65 67 65 70 62 67 68 65 64 now: 62 64 64 64 65 65 65 65 67 67 67 68 68 70 70 72 73 76 79 80 step 2. count the number of the numbers above, or assign an index as follows. string: 62 64 64 64 65 65 65 65 67 67 67 68 68 70 70 72 73 76 79 80 index: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 so the count is 20. The mode is the number most frequently observed. The mode is 65, which occurs four times. The median is the number in the middle. In this case, the 10th and 11th numbers both qualify for consideration. We take the average of the two numbers. The median is therefore 67. Alternate methods: 1) Use Microsoft Excel statistical functions of =mode() and =median() 2) Draw a bar graph with the horizontal axis of integers from 62 to 80. The y-axis is the frequency observed for that specific x value. For example, the frequency for 62 is one. The frequency for 63 is zero, and so on. The mode is the bar with the highest count. The median is not so obvious from a bar graph, unless the distribution is symmetric. Need some manual counting.

71 is the median of those numbers.

The median of the numbers 93 90 90 75 70 68 is 82.5.

The GCF of 68 and 70 is 2. The GCF of any two consecutive even numbers is 2.

62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77 and 78.

The three numbers will have a mean of 204/3 = 68. The two numbers are therefore 66, 68, 70.

To solve an average problem, add all of the numbers and divide by the total number of items you are averaging. So:65 + 70 + 75 = 210 / 3 numbers = 70

-20

60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78

60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80.

They are: 68+69+70 = 20768, 69 and 70.
