Answer:



Step-by-step explanation:
Given


Solving (a): The mean
Mean is calculated as:

This gives:



Solving (b): The median
Sort the data in ascending order:


The median is:



The 8th item on the sorted dataset is 7; So:

Solving (c): The mode

Because it has a frequency of 3 (more than any other element of the dataset).
Answer:
A bus traveling north at 25m/s
Step-by-step explanation:
Common sense
The answers to the question would be number 2, number 3, and number 5
Let's define our variables before anything else:
Kas = S
Jaspar = R
Jae = E
$400 is divided between Kas, Jaspar and Jae
This means S + R + E = 400
Kas has twice as much as Jaspar
This means that S = 2R
Jaspar has three times as much as Jae
This means that R = 3E
Because both of our smaller formulas have R, let's replace everything in the first formula with R
S + R + E = 400
plug in values
2R + R + R/3 = 400
multiply everything by 3 to get rid of the denominator
6R + 3R + R = 1200
add
10R = 1200
divide
R = 120
So Jaspar receives $120
