[need an answer now] a bag contains 15 marbles. the probability of randomly selecting a green marble is 1\3. the probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is 1/15. what is the probability of randomly selecting a red marble?

1\45
1\5
4\15
2/5

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
