THE solution is D.
you have 7 and 3 so commom multiple is 21
y-3*7=7
y-21=7
y=21+7
y=28
It can be deduced that the population proportion formulated shows that the proportion is 3/5.
<h3>How to calculate the population proportion</h3>
Your information is incomplete as the table isn't given. Therefore, an overview will be given. It should be noted that a population proportion simply means a fraction of the population that has a particular characteristic.
In this case, let's assume that the population is 2000 and the most preferred menu item is chosen by 1200 people. Therefore, the <em>population</em> proportion of the most preferred menu item will be:
= 1200/2000
= 3/5.

Answer:
The number of white horse to white horse is 9 : 31
Step-by-step explanation:
Given as :
The Total number of horses = 40
The number of white horses = 9
Let the number of black horses = x
So, x + 9 = 40
Or x = 40 - 9 = 31
∴ The number of black horses = 31
Now, The ratio of while to black horses = number of white horse : number of black horse
Or, number of white horse : number of black horse = 9 : 31
Hence The number of white horse to white horse is 9 : 31 Answer
Answer:
Step-by-step explanation:
<h3>Part A</h3>
- The base is a rectangle hence the parallel cut produces the same shape.
<h3>Part B</h3>
- The cut diagonal to base will produce rectangle as the cross section still contains two pairs of parallel lines
