Answer:
$3.50
Step-by-step explanation:
Given:
$10 for a 6, $7 for a 5, $4 for a 4, and no payoff otherwise
P(6) = 1/6 ; p(5) = 1/6 ; p(4) = 1/6 ; p(1,2or3) = 3/6 = 1/2
P(x) ____ 1/6 _____ 1/6 _____1/6 _____1/2
x______ 10 _______ 7 _____ 4 _______ 0
Expectwd value ; E(x)
Σx*p(x) = (1/6 * 10) + (1/6 * 7) + (1/6 * 4) + (1/2 * 0)
E(x) = 3.50
Answer:
x^2 - 49= (x+7) (x -7)
Step-by-step explanation:
Cot is more than 0 in 1st & 3rd quadrant
csc is more than 0 in 1st & 2nd quadrant
[ Here, quadrant I is common, when both will be greater than 0 ]
