A^2+b^2=c^2 so 4(4) +3(3) is 16+9= 25 and the square root of that is 5.
The first answer is going to be 15.42 (so b) and the second is going to be 10.67 (so a)
We want to find the probability that the two students chosen for the duet are boys. We will find that the probability that both students chosen for the duet are boys is 0.458
If we assume that the selection is totally random, then all the students have the same<em> </em><em>probability </em><em>of being chosen.</em>
This means that, for the first place in the duet, the probability of randomly selecting a boy is equal to the quotient between the number of boys and the total number of students, this is:
P = 11/16
For the second member of the duet we compute the probability in the same way, but this time there is one student less and one boy less (because one was already selected).
Q = 10/15
The joint probability (so both of these events happen together) is just the product of the individual probabilities, this will give:
Probability = P*Q = (11/16)*(10/15) = 0.458
So the probability that both students chosen for the duet are boys is 0.458

You would have to put this into a graph correct? Because if so, just put a point on the 12 on the y - axis and go up 2 and right 1 spot and place another dot. Then you will have correctly graphed the equation.
