Answer:
The probability that exactly two have flaws is P (x=2) = 0.2376
Step-by-step explanation:
Here
Success= p= 0.15
Failure = q= 0.85
total number= n= 8
Number chosen = x= 2
Applying the binomial distribution
P (x=x) = nCx p^x(q)^n-x
P (x=2) = 8C2 0.15 ²(0.85)^8
P (x=2) = 0.2376
The success is chosen about which we want to find the probability. Here we want to find the probability that exactly two have flaws so success would be having flaws therefore p = 0.15
Answer:
(36^t) / (6^(t^2)) is nonequivalent
(6^(t^2)) / (36^t) is equivalent
(6^(t^2)) * 36^t is nonequivalent
Step-by-step explanation:
We can use the exponential quotient law for this problem.
a^x / a^y = a^x - y
(6^(t^2)) / (6^2t) = (6^(t^2)) / (36^t)
Answer:
It takes 4 minutes per block and she can walk 12.5 blocks in 45 minutes.
Step-by-step explanation:
20 / 5 = 4 minutes per block
20 + 20 + 5 = 45
5 + 5 + 2.5 = 12.5
