Answer:
Step-by-step explanation:
Given
See attachment for cumulative frequency histogram
Solving (a): Swimmers between 200yd and 249yd
To do this, we simply read the data from the 0 mark
From the histogram, we have:
and
So:
This gives:
Solving (b): Swimmers between 150yd and 199yd
To do this, we simply read the data from the 0 mark
From the histogram, we have:
and
So:
This gives:
Solving (c): Total swimmers
To do this, we simply read the longest bar of the histogram
Hence:
Answer: 2.117647
Step-by-step explanation:
So first let me assume that the Total profit of the racquets are 8 percentage and not individually.
Now to find the profit we can do
20 x 100= 2000
Now
8=x/2000*100
X= 160
And now for loss
10x80=800
Now
15= x/800*100
X=120
Now profit =
160-120 = 40
The profit was only 40
