Answer:
f(3/2) = 13√13 ≈ 46.872167
Step-by-step explanation:
Put 3/2 where x is and evaluate.
f(3/2) = 13^(3/2) = 13^(1 +1/2) = 13√13
f(3/2) ≈ 46.872167

Because not drawing the circle graph of the burger could lead you to draw the wrong conclusion
Answer:
A. E(x) = 1/n×n(n+1)/2
B. E(x²) = 1/n
Step-by-step explanation:
The n candidates for a job have been ranked 1,2,3....n. Let x be the rank of a randomly selected candidate. Therefore, the PMF of X is given as
P(x) = {1/n, x = 1,2...n}
Therefore,
Expectation of X
E(x) = summation {xP(×)}
= summation {X×1/n}
= 1/n summation{x}
= 1/n×n(n+1)/2
= n+1/2
Thus, E(x) = 1/n×n(n+1)/2
Value of E(x²)
E(x²) = summation {x²P(×)}
= summation{x²×1/n}
= 1/n
