89+84+90+94+98=455 455/5= 91 91 is the mean.
87
The average of 82 percent, 94 percent, 89 percent, and 91 percent is 89 percent.
83.7
87
Put them in order, least to greatest. 62, 78, 84, 89, 94, 94, 96, 98 The range is the smallest subtracted from the largest. 98 - 62 = 36 The range is 36. The median is the average of the middle two. 89 + 94 = 183 divided by 2 = 91.5 The median is 91.5
composite numbers 89-97 = 90, 91, 92, 93, 94, 95, 96
The median is 86.
90.
The range is 36 because 98-62=36. Hope this helps :)
94-89 = 5
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.
