Answer:
a) 0.15
b) 0.2
c) 0.6
Step-by-step explanation:
We are given the following in the question:
A: Stopping at first signal
B: Stopping at second signal
P(A) = 0.35
P(B) = 0.55
Probability that he must stop at at least one of the two signals is 0.75
a) P(at both signals)
0.15 is the probability that motorist stops at both signals.
b) P(at the first signal but not at the second one)
0.2 is the probability that motorist stops at the first signal but not at the second one.
c) P(at exactly one signal)
0.6 is the probability that the motorist stops at exactly one signal.
The answer is t = (y + 2n)/r
The expression is: rt - 2n = y
Rearrange it so that only rt is on the left side of the equation: rt = y + 2n
Rewrite the left side of the equation: r * t = y + 2n
Divide both sides of the equation by r: r * t / r = (y + 2n)/r
r can be cancelled out on the left side of the equation: t = (y + 2n)/r
Answer:
7/20
Step-by-step explanation:
There are 20 customers (the denominator) and 7 can pay cash (the numerator)
Add 1/9 to both sides
n^2+2/3n+1/9=0
factor
I recognize a perfect square binomial
(a+b)^2=a^2+2ab+b^2
1n^2+2(n)(1/3)+(1/3)^2
(n+1/3)^2=0
set to zero
n+1/3=0
minus 1/3
n=-1/3
