Answer:
7
Explanation:
So basically, there are 4 segments: 15-30, 30-45, 45-60, 60-75.
There is also a list of values.
If these values fall between 15-30, for example, it is considered a freqeuncy of 1.
If a second value also falls between 15-30, it is considered to then have a frequency of 2.
Every value that falls under a range of values, such as 15-30, is counted as a freqeuncy of 1.
So, lets look at 15-30.
There is a freqeuncy of 3.
This means that 3 values were in between 15 and 30,
Now, we need to know how many values were above 30.
This means we do not count values that are in the 15-30 segment.
However, we do want to look at the freqeuncy in 30-45, 45-60, and 60-75.
In 30-45 we have a frequency of 3.
In 45-60 we have a frequency of 2.
In 60-75 we have a frequency of 2.
To find the amount of values above 30, we must add these all together:
3+2+2
=
7
So 7 values have a price above 30!
Hope this helps!
