The demand function for a certain brand of backpacks is p= 50 ln (50/x) for 0< x <= 50 where p is the unit price in dollars and x is the quantity (in hundreds) demanded per month.

a. Find the elasticity of demand, and determine the range of prices corresponding to inelastic, unitary, and elastic demand.
b. If the unit price is increased slightly from $50, will the revenue increase or decrease?

ab will be equal to

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
