1) JPR, JRP, PJR, PRJ, RJP, RPJ
2) To start with there are 4 green marbles and a total of 6 marbles.
First drawing: p(green) = 4/6 = 2/3
He replaces the first marble, so for the second drawing he has again 4 green marbles out of a total of 6 marbles.
p(green) = 4/6 = 2/3
The combined probability is the product of the 2 probabilities.
p(green followed by green) = p(green) * p(green) = 2/3 * 2/3 = 4/9
3)
Total number of combinations of 3 different shirts and 2 pairs of pants is 3 * 2 - 6. You are interested in a single combination out of a possible 6.
p(white shirt & tan pants) = 1/6

Answer:
Step-by-step explanation:
f(x) = x^3 - 3x^2 - 28x + 60
x(x^2-3x-28)+60
Factor the inside of the parenthesis
Multiples of 28: (1X28),(2X14),(4X7). 7-4=3, 7 & 4 is the correct multiple.
x(x-7)(x+3)+60
Roots: 0,7,-3,6
Also you can plug your function into Desmos and see where it crosses the x-axis.
Answer:idk either sorry wish icould
Step-by-step explanation:
Let x and y represent the two angles.
.. x + y = 90 . . . . . . two angles are complementary
.. x -2y = 15 . . . . . . one angle is 15 more than twice the other (y = smaller angle)
Subtract the second equation from the first.
.. (x +y) -(x -2y) = (90) -(15)
.. 3y = 75
.. y = 25
The smaller angle is 25 degrees.
