It’s c
Step-by-step explanation:
Answer:
97.5
Step-by-step explanation:
Supplementary means the angles add up to 180°
So,
m∠A = 180 - m∠B
m∠A = 180 - 82.5
m∠A = 97.5
It would be b. the first ratio is
1kL
----
1000
so you would match up the kL and not know how many regular liters there are.
8kL

x
Answer:
9^2
Step-by-step explanation:
we do 3*3 which is 9, and then 9 to the second power
P ( A ) = 0.45 - probability that the land has oil,
P ( B ) = 0.8 - probability that the test predicts it
P ( A ∩ B ) = P ( A ) · P ( B ) = 0.45 · 0.8 = 0.36
Answer: The probability that the land has oil and the test predicts it is 36 %.
