72

difference decreases by 1 each time

9 = 107 - 98

8 = 98 - 90

7 = 90 - 83

6 = 83 - 77

5 = 77 - 72

4 = 72 - 68

3 = 68 - 65

Least Common Multiple (LCM) for 107 68 4 is 7,276.

It is closer to 68. 68-59=9, so you find the middle number between 59 and 69 by dividing 9 by 2, which is 4.5. 59+4.5=63.5 65 is bigger than 63.5, which is the middle number, so its closer to 68.

65+ 3 = 68 because 5+3=8 and leave 6 alone equals 68.

107/68 is not a high blood pressure. On an adverage healthy adult a normal blood pressure is 120/80.

To solve a problem such as this, we must first determine the pattern that has created the already existing list:61 68 82 92 103 107+7 +14 +10 +11 +4If you look at the numbers that have obviously been added to get the new number, it should be obvious (laying the problem out like this) that those numbers are derived by adding the digits of the previous number and then adding the sum of those digits to that same number. For example:61 = 6 + 1 = 7, therefore 61 + 7 = 6868 = 6 + 8 = 14, therefore 68 + 14 = 82 and so on...Thus, the answer would be 107 = 1 + 0 + 7 = 8, therefore 107 + 8 = 115

(s + 65 + 62 + 70 + 68) / 5 = 66.2 &there4; s + 65 + 62 + 70 + 68 = 331 &there4; s = 331 - 65 - 62 - 70 - 68 &there4; s = 66

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

square-root of 68 times square-root of 68 = 68 (square-root of any number) squared is that number

68 of 312 refers to 68. 312 is actually the total number.

The original set would be 107, 98, 90, 83, 77, x, 68, and 65. The pattern of this set of numbers is that the first term is subtracted by 9, the next by 8, the next by 7, and so on. Therefore, the term x would be 72, which is 5 less than 77 and 4 more than 68.

28 and 68 are divisible by 4. 68/4 = 16 28/4 = 7

No. If you can write the number on paper, it's rational. 68 is the ratio of 68 to 1.

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.

The only composite factor of 65 is 65. The composite factors of 80 are 4, 8, 10, 16, 20, 40, 80

65-68. Call S&amp;W and they will tell you when it left the factory.

13 goes into 68 5 times which equals 65.
