The mean of any set of numbers is the sum of those numbers divided by how many numbers there are. Here, the sum is 99+97+91+89+81+76=533. When you divide 533 by 6 (the total number of numbers), you get 88.83333... repeating forever. In mixed number form, this is 88 and 5/6.
41 is prime. 51 is composite. 51=3 x 17 . 71 is prime. 81 is composite. 92 91 is composite. 91 = 7 × 13
Multiples of.... 3 - 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96 & 99 4 - 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96 & 100 9 - 63, 72, 81, 90, 91 & 99
These steps can reduce our work: First of all we will write all the even numbers between 89 and 97: 90, 92, 94 & 96. Then multiples of 5: 90 & 95. Multiples of 3: 90, 93 & 96 and also the multiple of 7 which is 91. There is no other number left between 89 & 97. Therefore, numbers between 89 & 97 are all composite numbers.
61 and 71 are prime numbers the rest are composite numbers
53, 59, 61, 67, 71, 73, 79, 83, 89, 91, and 97
Place the values in ascending order: 76, 81, 89, 91, 97, 99. There are 2 middle numbers; 89 & 91. The median is the mean of the 2 middle numbers; or (89+91)/2 or 90.
86
The MAD is 8.
That's an infinite list. 81, 83, 85, 87, 89, 91 and so on.
To find the average, add the scores and divide the sum by how many scores you are adding: 81 + 76 + 91 + 73 + 79 = 400 ÷ 5 = 80.
-1,400
-91 - (+76) = -91 - 76 = -167 -91 - (+76) = -91 - 76 = -167 -91 - (+76) = -91 - 76 = -167 -91 - (+76) = -91 - 76 = -167
86 is the mean of 85, 91, 76, 85, and 93.
89+84+90+94+98=455 455/5= 91 91 is the mean.
There is no mode because all the numbers are different
It is 92.
(79, 81, 82, 91, 93, 95, 95) The mean is 88 The mode is 95 The median is 91
