First, you need to put them in order
53kg, 55kg, 61kg, 61kg, 76kg, 91kg, 98kg, 105kg, 120kg
For mean, you add them all up and divide by the amount of numbers (9)
720/9 = 80
For median, you find the middle number (76kg)
For mode, you find the number that appears the most (61kg)
Mean: 80
Median: 76
Mode: 61
Here, you do the same as the previous one, keeping in mind that X cuts TW in a 2:1 ratio.

Answer:
If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.
4 hours at 60 miles per hour = 4*60 = 240 miles
6 hours at 65 miles per hour = 6*65 = 390 miles
This is a total of 630 miles. There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

um ok is there any more to that question
Step-by-step explanation:
<span>A line graph is used to show a trend
over a period of time. It is plotted as a series of points,
which are then joined with straight lines. The ends of the line graph do not have to join to the axes.
</span><span>A scatter plot is a type of plot
or mathematical diagram using Cartesian coordinates to display values
for typically two variables.
The difference between a line graph and a scatter plot is that a</span><span> line graph presents continuous and linked data, while a scatter plot presents unlinked data.</span>
