Answer:
0.22
Step-by-step explanation:
p= m/v
in this problem, we divide 12 goldfishes by 45 cubic feet. This is equal to 0.27 goldfish per cubic feet..This is equal to 0.27 goldfish per cubic feet.
The answer is 0.22
Answer:
P(X ≥ 5) = 0.6667
Step-by-step explanation:
Waiting for a train that comes once in 0 to 15 minutes is a uniform probability distribution problem.
For a uniform probability distribution, the probability function is given as
P(X) = f(x) = [1/(b-a)] for (a≤x≤b)
where a = lower limit of the uniform distribution sample space = 0 mins
b = upper limit of the uniform distribution sample space = 15 mins
But P(X≥x) = 1/(b-a) ∫ dx (with the Integral evaluated from x to b)
So, the probability that a person would wait at least 5 minutes for a train = P(X ≥ 5)
P(X ≥ 5) = 1/(b-a) ∫¹⁵₅ dx = 1/(15-0) ∫¹⁵₅ dx
P(X ≥ 5) = (1/15) × [x]¹⁵₅ = (1/15) × (15 - 5) = (10/15) = (2/3) = 0.6667
Hope this Helps!!!
Answer:
The demensions of the are W=10 and L=5.
Step-by-step explanation:
The width is 10 because the lenth is 5 less so when you add up the 10 and 5 it equals 15, multiply it by 2 and you get 30.
