Answer:
D)
Step-by-step explanation:
For every x, there can be only y.
A, B and C violate that.
Answer: C
Explanation:
200 x 50 = 10,000
10,000 square metres = 1 hectare
Answer:
92
Step-by-step explanation:
5x - 2y + (7x - y) = 5 * 7 - 2 * (-2) + (7 * 7 - (-2)) = 35 - (-4) + (49 + 4) = 39 + 53
= 92
8 large red, 5 small red, 7 large blue, 4 small blue:
totally = 24 marbles
P(red)= 13/24
let A red and B large
P(A/B)= P(A∩B)/P(B)
P(B)= 15/24 =.625
P(A∩B)= 8/24 = .333
P(A/B) =.333/.625 =.533
P(B/A) =.625/.333= 1.875
so the probability of p(large/red) is larger.
