Answer:
The probability that exactly 6 transactions will be made at an ATM in the next 20 minutes = 0.06306 = 0.0631 to 4d.p
Step-by-step explanation:
This is a Poisson distribution problem
The Poisson distribution formula is given as
P(X = x) = (e^-λ)(λˣ)/x!
where λ = mean = 10 transactions per 20 minutes
x = variable whose probability is required = 6 transactions in the next 20 minutes
P(X = 6) = (e⁻¹⁰)(10⁶)/6! = 0.06306
Answer:
exact form is 56/37
decimal form is 1.513
mixed number form is 1 19/37
Step-by-step explanation:
Answer:
35:1
Step-by-step explanation:
divide each by two
Answer:
Step-by-step explanation:
So we have:
Multiply both sides by 11:
The right side cancels:
Multiply the left:
Thus, the value of q is 33.
