Answer:
52.5% probability that A occurs given B occurs
Step-by-step explanation:
Suppose we have two events, A and B, the conditional probability formula is:

In which
P(A|B) is the probability of A happening given that B happened.
is the probability of both A and B happening.
P(B) is the probability of B happening.
In this problem, we have that:

So

52.5% probability that A occurs given B occurs
She regrouped the numbers instead of multiplying like 8b(2b-r) -4r(2b-r).
Answer: first to tell you how to do it we start with y=mx=b or y1-y2/x1-x2 then put the values in. and slove for y
Step-by-step explanation:
Answer:
40 miles
Step-by-step explanation:
let distance be d and time be t
Since d varies directly with t, then the equation relating them is
d = kt ← k is the constant of variation
To find k use the condition d = 75 when t = 3
k =
=
= 25
d = 25t ← equation of variation
when t = 1.6, then
d = 25 × 1.6 = 40 miles
