Answer:
8km / 9 hours
Step-by-step explanation:
see the point is on
x axis = 9 = 9 hours
y axis = 8 = 8 kilometers
so the average speed of bus is 8 km in 9 hours
To visualize better, look at it like this:
First, see if you can simplify 3/2. You can't, so leave it like that.
The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top (
)
Put that on the top, and you get
Answer:
equals -43
Step-by-step explanation:
Given:
The box plot of a data set.
To find:
The first quartile of the data.
Solution:
In a box plot, the left end point is the minimum value and the right end point is the maximum value. The left end of the box is the first quartile and right end of the box is third quartile. The line inside the box represents the median.
From the given box plot, it is clear that the left end of the box is at 20.
In the box plot,
Minimum value = 0
First quartile = 20
Median = 40
Third quartile = 90
Maximum = 120
Therefore, the first quartile of the data is 20.
