The answer would be 84 students. Why? because 14/27 * 162 = 84
By definition of conditional probability,
But any event and its complement cannot occur simultaneously; they are disjoint, so the probability of their intersection is 0. So the conditional probability is also 0.
Answer:
x=6/31, y=147/31. (6/31, 147/31).
Step-by-step explanation:
y=-22x+9
y=40x-3
-----------------
-22x+9=40x-3
9=40x-(-22x)-3
9=40x+22x-3
9=62x-3
62x=9+3
62x=12
x=12/62
simplify,
x=6/31
-----------------
y=40(6/31)-3=240/31-3=240/31-93/31=147/31
x=6/31, y=147/31.
1. 1 (1 + 1 = 2 / 1 x 9 = 9)
2. 1 (1+ 6 = 6 / 1x 7 = 7)
3.1 (1 + 1 = 2 / 1 x 7 =7)
