Hey there! :)
Your answer is mean
_____________________________________________________________
Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.
Finding the mode is pretty useless because you can't do much with the score that you got the most.
Range isn't that helpful because it's the difference between your best and worst score.
Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________
Therefore, the answer is mean
Hope this helps :)
Answer:
$17.20
Explanation:
To easily get the ratio figured out between Paul, Colin and Brian, try seeing how much the ratio adds up to. With 2:3:4, there is a total of 9; so take 1/9th of 77.40 to get $8.60
You can convert these ratios to fractions, with Paul getting 2/9ths, Colin getting 3/9ths and Brian getting 4/9ths
As Brian is effectively getting double the amount of money, you can just take the amount Paul is getting in tips and use that as the reference for how much Brian is earning which is $8.60 x 2 or in this case, $17.20
