Answer:
p= 3
Step-by-step explanation:
4p +24-11=25
4p +13=25
4p= 25-13
4p = 12
p= 12/4
p= 3
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
11yd is the diameter and circumference is 2πr = 2π(d/2) = πd = 11π yd
Answer:
Let's simplify step-by-step.
2x+3y2−2(x−y2)
Distribute:
=2x+3y2+(−2)(x)+(−2)(−y2)
=2x+3y2+−2x+2y2
Combine Like Terms:
=2x+3y2+−2x+2y2
=(3y2+2y2)+(2x+−2x)
=5y2
Answer:
<em><u>=5y2</u></em>
