URGENT PLEASE HELP Find x Round to the nearest tenth if necessary
Answers
Step-by-step explanation:
Mean: You add up all the numbers then divide it by the amount of numbers there are : 72 + 53 + 64 + 99 + 84 + 73 + 99 + 100 + 85+ 91+ 93 + 74 = 987 / 12 = 82.25 => 82.3 (rounded to nearest tenth)
Median: You put the numbers in order and the median is the number in the middle (if there's an even amount of numbers, you find the average of the 2 numbers that are in the middle, and that would be the median) : 53, 64, 72, 73, 74, 84, 85, 91, 93, 99, 99, 100
84 + 85 = 169 / 2 = 84.5
Mode: The number that comes up most often than the other numbers: 99 is the mode because it comes up 2 times while the other numbers come up only once.
Range: You take the smallest number and subtract it from the biggest number (remember that the range is only one number!!!): 100 - 53 = 47
