Afair die is rolled 8 times. a. what is the probability that the die comes up 6 exactly twice? b. what is the probability

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Solve for the equation. 4x - 13 = 2x + 9

If f(x)=3 over x+2 - square root x-3 then f(7)=
