What is the blood type of the unknown parent?
Vinil7 [7]

If the genotype is lAi0 and one gene is, let's say, from mother (lA), we know exactly that the other gene is from father (i0).

So, father's genotype is lBi0 (a).

If a monopolist can sell 7 units when the price is $4 and 8 units when the price is $3, then marginal revenue of selling the eig
pychu [463]

The marginal revenue of selling the eighth unit is $-4.

A monopolist is the only producer in the industry. A monopolist operates in a monopoly. The monopolist sets the market price of their products.

Marginal revenue is the change in total revenue when quantity sold increases by one unit.

Marginal revenue = change in total revenue / change in quantity sold

change in total revenue = ($3 x 8) - ($4 x 7) = $-4

change in quantity sold = 8 - 7 = 1

Marginal revenue = $-4 / 1 = $4
