Using the tables to answer the question, the correct option is D.
Only table B represents a function
A relation/table will represent a function if each value of x is attached to a unique value of y.
That is, no value of x must be mapped to more than one value of y.
By considering the tables represented
Set A = {(-5, 2), (-8, 5), (-5, 8)}
As clearly shown above, when x = -5, y = 2 and 8. This means that there are more than 1 value of y for a single value of x, therefore, table A does not represent a function.
Set B = {(-5, 2), (-8, 5), (-11, 2)}
As shown above, all values of x have different values of y. Therefore, table B represents a function.

<span>To find the expected recorded score, we need to find the sum of (x + y) times P(x +y), which gives us 14.4. The expected recorded score goes through the same process, but we only use the maximum scores and this gives us 9.75</span>
Answer:
Step-by-step explanation:
Answer:
(8x + 100) litres
Step-by-step explanation:
According to the question,
- Given, In a village there are 8 water tanks to collect rainwater. On a particular day, x litres of rainwater is collected per tank. If 100 litres of water was already there in one of the tanks.
Therefore,
Number of water tanks = 8
Rainwater collected by each tank = x litres
∴ Rainwater collected by 8 tanks = 8x litres
But, 100 litres of water was already there in one of the tanks.
- So, the amount of water in the tanks = (8x + 100) litres
