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.

2 lines are parallel unless both lines have the same slope and different y-intercept

Answer:
1. About 68% of the data lie within one standard deviation of the mean.
2. About 95% of the data lie within two standard deviation of the mean.
3. About 99,7% of the data lie within three standard deviation of the mean.
Step-by-step explanation:
1. 34 + 34 = 68
2. 68 + 13,5 + 13,5 = 95
3. 95 + 2,35 + 2,35 = 99,7
