Answer:
450 ml.
Step-by-step explanation:
Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.
We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:
We are also told that Alla drinks 50% more than Balla. We can represent this information as:
From equation (1) we will get,
Upon substituting this value in equation (2) we will get,
Upon distributing 1.5 to right hand side of the equation we will get,
Upon adding 1.5x to both sides of equation we will get,
Let us divide both sides of our equation by 2.5.
Therefore, Alla drank 450 ml of water.
Part A:What percentage of the total students surveyed like both watching television and reading?
The total amount of student is 230
The amount of students that like to read and watch television is 80
As a fraction it is 80/230
Turn that to a percentage
It is:34.7826%
Part A=34.7826%
Part B:What is the probability that a student does not like watching television also does not like reading?
On the table it shows 20
So the probability is 20/230
Part B=20/230
The total amount of student is 230
The amount of students that like to read and watch television is 80
As a fraction it is 80/230
Turn that to a percentage
It is:34.7826%
Part A=34.7826%
Part B:What is the probability that a student does not like watching television also does not like reading?
On the table it shows 20
So the probability is 20/230
Part B=20/230
