Answer:

0.288

0.308

Explanation:

Given :

Mining sector = 45

Financial sector = 72

IT sector = 32

Production sector = 101

Total number of companies :

(45 + 72 + 32 + 101) = 250

A.)

Probability that a randomly selected company is in the financial sector

Recall :

Probability = required outcome / Total possible outcomes

P(company = financial) = (number of companies in financial sector / total number of companies)

P(company = financial) = 72 / 250 = 0.288

B.)

Company is either a mining or IT company :

P(company = Mining or IT) = (number of mining + number of IT Companies) / total number of companies

P(company = Mining or IT) = (45 + 32) / 250 = 77 / 250 = 0.308

Ivanshal [37]

Suppose the local slaughterhouse gives off an unpleasant stench. the price of meat would then be too low because not all of the costs are accounted for in the marketplace.

When the price of an item increases, buyers tend to purchase less of that item due to both the substitution effect and the income effect. When the pizza was on sale at the student council he was selling for $2, Mo didn't buy any. When the price dropped to $1.75 he bought one for Moe's daily lunch.

An increase in demand and a decrease in supply raises the slaughterhouse price, but the effect on the equilibrium quantity cannot be determined. 1. For each quantity, consumers should place a higher value on the goods and producers should set a higher price to supply the goods. Therefore, the price is higher.
