Please see the attachment for the step by step answer
A simple way to find this using mathematical methods is to set up a proportion:
Then you would cross multiply getting:
900=10x (then divide by 10 on both sides to get the variable alone)
x=90
So 90 inches will represent 900 miles
Answer:
Median = 70
Range = 10
Step-by-step explanation:
The median of a set of data is the middlemost number in the set. The median is also the number that is halfway into the set.
72, 77, 77, 77, 70, 75, 70, 67, 76, 73
There are ten numbers, so you solve the equation:
10 ÷ 2 = 5
The fifth number is 70
The range of a set of data is the difference between the highest and lowest values in the set.
72, 77, 77, 77, 70, 75, 70, 67, 76, 73
The greatest number is: 77
The lowest number is: 67
So you find the difference between them:
77 - 67 = 10
