The answer is 3! If u would like me 2 explain how I got that quotient just ask and I will gladly do so!
Answer:

Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
If you are trying to find the area of the triangle, you would do base x height.
14 x 5
So the answer would be 70
If you have access to a TI-83 or 84-Plus calculator, try the following command:
binompdf(10, 0.25, 4). The output I get is 0.1460. Thus, the probability of getting a "4" is 0.1460.
If you do not have such a calculator, you may be able to find this result in a binomial probability table. Look for the table for n=10. It lists the possible outcomes {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. In the column labeled 0.25 (the binomial probability), find the probability of getting a "4."
