Answer:
6x -24
Step-by-step explanation:
You just develop :
6(x-4)
6*x - 6*4
= 6x-24
The final answer is the same as given, which is cosecA= 2.....
hope it helped ☺️
Answer;
32 pounds of the blend can be made
Explanation;
If light roast is 25%, then the other part will be 100-25 = 75%
Now the ratio of the light roast to the other part will be;
25% to 75% = 1 to 3
So if light toast is 8 pounds, the other part will be 3 * 8 = 24 pounds
So the amount of blend to be made will be 8 pounds + 24 pounds = 32 pounds
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)]
