The median is a halfway point in the set of data.
List the numbers in order from smallest to largest:
111, 129, 144, 149, 152, 162, 166, 171
Because there are an even number of values in the data set, find the two middle numbers, add them together and then divide by 2:
Median = ( 149 + 152 ) /2
Median = 150.5
The expression of 25t +45m shows the total number of miles driven at both speeds. In order to solve this equation you would need to know the total number of hours driven in order to multiply that by the appropriate speed in terms of miles per hour.
When each x value has only one y value, the relation is a function
When you round; you round down if the number in the selected column is below 5 and you round up if the number is 5 and above.
Thus; if you apply this to your question:
784,072 then round up and you get 790,000
Answer: 1 and 3
It's because they both divide down lower than 1
