Kayla and bianca each bought one raffle ticket at the school fair. if 50 tickets were sold, what is the probability kayla bought ticket number 7 and bianca bought ticket number 10?

The total tickets sold at the fair = 50 tickets.

Kayla and Bianca each bought one ticket, it could be any numbered. We can start with anyone and find their probability.

If Kayla got ticket numbered #7, its probability would be 1 out of 50.  

Then there would be 49 tickets remaining for Bianca at the fair.

If Bianca got ticket numbered #10, it probability would be 1 out of 49.

Total probability of (Kayla getting #7 AND Bianca getting #10) would be 1/(50x49) = 1/(2,450) = 0.0004081 = 0.0408%.

Hence, final answer is

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
