In a class of 21 students, 11 students passed the test. A total of 14 students completed their homework. If there are 4 students who did not pass the test AND did not complete their homework, what is the probability that a student passed the test GIVEN THAT they completed the homework?

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.

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

$452.90 because you needed to round to the nearest cent
