Add them together. There are 15 numbers so divide the sum by 15.
You can, of course, use the calculator that comes as part of your computer.
To calculate the mean of the numbers 56, 77, 68, 63, 69, 68, 80, 71, and 63, first sum them: 56 + 77 + 68 + 63 + 69 + 68 + 80 + 71 + 63 = 616. Then, divide the total by the number of values, which is 9. Thus, the mean is 616 ÷ 9 = 68.44.
The mean (average) of 76, 63, 79, 63, and 74 is 71.
Mean = (63+65+52+71+67+52)/6 = 370/6 = 61.66... recurring.
67.6363
It is 71-8 = 63.
The common factor of 63 and 71 is and 1.
71/68 x 100 = 104.4117647058823529 recurring (that is, 104.41176470588235294117647058823529...) percent.
71 - 8= 63
21 is a factor of 63 (21 * 3 = 63).71 is a prime number.Since 71 has no common factors with 63, they must be multiplied together to find their least common multiple.Thus, the least common multiple (LCM) of 21, 63 and 71 is 63 * 71 = 4473.
The least common multiple of the numbers 68 and 71 is 4,828.
The number that is 3 more than 68 is 71. This is calculated by simply adding 3 to 68, resulting in 68 + 3 = 71.
71 is prime.
