Step-by-step explanation:
5p=12h
3p=?(h)
12×3=5h
36=5h
h=36/5
h=7.2 hours
Basically, we need to find the lowest common multiple of 10 and 15.
that multiply would be 30. That means that the bells will ring together in 30 minutes.
So 30 minutes from 6 p.m. is 6:30 p.m. <==
Answer:
230
Step-by-step explanation:
Answer:
p(4 successes) ≈ 7.7%
Step-by-step explanation:
p(k successes in n trials) = C(n,k)·p^k·(1-p)^(n-k)
You have n=5, k=4, p=0.4, so the probability is ...
p(4 successes) = C(5,4)·(0.4)^4·(1 -0.4)^1 = 5·0.4^4·0.6 = 0.0768
p(4 successes) ≈ 7.7%
