Step-by-step explanation:
Tan is adjacent over hypotenuse
9514 1404 393
Answer:
60
Step-by-step explanation:
Let x represent the number of members last summer. Then 90% more is 1.9x. We are told this is 114, so we have ...
1.9x = 114
x = 114/1.9 = 60
There were 60 members last summer.
Answer:
calculate P(X=1) + P(X=2) +...+ P(X=12) using the binomial formula or an individual table in excel
calculate the P(X ≥ 12) using the binomial formula or a cumulative table in excel
Step-by-step explanation:
For a binomial distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
n = number of trials = 12 ; x = number of successes
p = probability of success = 0.2% = 0.002
1 - p = 1 - 0.002 = 0.998
Probability that atleast 1 is broken ;
p(1) + p(2) + p(3) +... + p(12) ;
This can be calculated by summing the values obtained using the binomial formula or in excel.
Alternatively, using the binomial formular or excel, the cumulative probability could be obtained as P(x ≥ 1)
