The__of an angle is the ratio of the opposite leg length to the hypotenuse length
2 answers:
Answer:
Sine
Step-by-step explanation:
As per the trigonometric ratios "sine" of any angle is the ratio of the side which is exactly opposite to the angle and the hypotenuse.
The formula is
The hypotenuse is the longest side in any right triangle. The side containing the angle is called the base. The side which is opposite to the angle is called the perpendicular. So basically it is " Sine" of any angle is ration of "perpendicular " to the "Hypotenuse"

Answer:
a. .
b.
Step-by-step explanation:
By the definition, the expected value of a random variable X with probability mass function p is given by where the sum runs over all the posible values of X. Given a function g, the random variable Y=g(X) is defined. Note that the function g induces a probability mass function P' given by P'(Y=k) = P(X=g^{-1}(k)) when the function g is bijective.
a. Note that for 1/3ln(2)+1/6ln(5) by choosing the function g(x) = ln(x) the expression coincides with E(g(x)), because if Y = g(x) then E(Y) = P'(Y=1)*ln(1)+P'(Y=2)*ln(2)+P'(Y=5)*ln(5) = P(X=1)*ln(1)+P(X=2)*ln(2)+P(X=5)*ln(5).
b. On the same fashion, the function g(x) = xe^{xt} fullfills the expression of E[g(X)]
