When the events are independent
P(A∪B) = P(A) + P(B) - P(A∩B) . . . . where P(A∩B) = P(A)·P(B)
Substituting the given numbers, you have
P(A∪B) = 0.3 + 0.9 - 0.3·0.9
P(A∪B) = 0.93
We know, Average speed = distance / time
So, s = 18 / 1/2
s = 18 * 2 / 1
s = 36 mph
In short, Your Answer would be: 36 mph
Hope this helps!
Answer:
D. 12
Step-by-step explanation:
Answer:
12.5 miles
Step-by-step explanation:
5x2.5=12.5 miles
Y < (x - 4)(x + 2)
so the critical points are -2 and 4
(-2,-1) will be in the solution
( 0,-2) will not
(4,0) will not.
the answer is ((-2,-1)
