Answer:
Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0
Step-by-step explanation:
According to tangent sub identity
Tan(A+B) = TanA+TanB/1-tanAtanB
Applying this in question
Tan(w+Pi) = tan(w)+tan(pi)/1-tan(w)tan(pi)
According to trig identity, tan(pi) = 0
Substitute
Tan(w+Pi) = tan(w)+0/1-tan(w)(0)
Tan(w+Pi) = tan(w)/1
Tan(w+Pi) = tan(w) (proved!)
Hence the correct option is
Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0
Answer :
0.2322
Step-by-step explanation:
Proportion, p of those who used e - ticket to get boarding pass = 112 / 280 = 0.4
p = 0.4
1 - p = 1 - 0.4 = 0.6
Number of samples, n = 8
P(x = 4)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 8C4 * 0.4^4 * 0.6^4
P(x = 4) = 70 * 0.0256 * 0.1296
P(x = 4) = 0.2322432
P(x = 4) = 0.2322
