A tile is drawn from a bag at random and then replaced. The probability of drawing a blue tile is 80% and the probability of drawing a red tile is 20%.
What is the expected number of blue tiles in 25 draws?

step-by-step explanation:

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.

answer: y=0 if that is what u r looking for

d 600 because 15*10*2=300

300+300=600
