(a)
To calculate: The probability that both the person selected at random from a group of 20 people are left handed. In the group, 15 peoples are right-handed, 4 are left-handed and 1 is ambidextrous. Two peoples are selected at random without replacement.
(b)
To calculate: The probability that one person is right-handed and one is left-handed which are selected at random from a group of 20 people. In the group, 15 peoples are right-handed, 4 are left-handed and 1 is ambidextrous. Two peoples are selected at random without replacement.
(c)
To calculate: The probability that both the peoples selected at random from a group of 20 peoples are right-handed. In the group, 15 peoples are right-handed, 4 are left-handed and 1 is ambidextrous. Two peoples are selected at random without replacement.
(d)
To calculate: The probability that both the peoples selected at random from a group of 20 peoples are ambidextrous. In the group, 15 peoples are right-handed, 4 are left-handed and 1 is ambidextrous. Two peoples are selected at random without replacement.

How fast is the cost per month changing when production is changing at the rate of 14 units per month and the production level is 80 units? Costs are increasing at the rate of $ (Round to the nearest dollar as needed.) per month at this production level.arrow_forward

Hint: Adapt the proof from the lecture notes for finding the dual of the Lorentz cone. Alternatively, prove the formula (AL)* = (AT)-¹L*, for any cone LC R³ and any 3 × 3 nonsingular matrix A with real entries, where AL = {Ax = R³ : x € L}, and apply it to the 3-dimensional Lorentz cone with an appropriately chosen matrix A.arrow_forward
