Answer: The attendant’s expected earn- ings for the period between 4:00 P.M and 5:00 P.M is <u>$12,67.</u>

The expected value of the discrete random variable X is

<h2>= E (x) = ∑× f(x)</h2><h2>= 7 × 1/12 + 9 × 1/12 + 11 × 1/4 + 13 × 1/4 + 15 × 1/6 + 17 × 1/6 = <u>12,67.</u></h2><h2><u /></h2>

Why is a price floor set above an equilibrium price tends to cause persistent imbalances in the market?
kotykmax [81]

Answer:

A price floor set above the equilibrium price will result in a surplus of supply.  

Explanation.

An equilibrium price refers to the price at which demand for a service or product is equivalent to the quantity of the product or service supplied in the market.

Setting a price floor above the equilibrium price essentially means that the set prices will be higher than what demand is willing to pay for the product or service. Demand will therefore purchase fewer quantity of the product offered by supply at the prevailing price than they would have at equilibrium price.

Since the price floor will raise the product price to considerably higher than the equilibrium price, supply will be willing to provide higher volumes of the product at the prevailing price than at equilibrium price.

This will lead to a mismatch in the market between supply and demand resulting into a surplus.

A newspaper headline writer found that the more adjectives she put in the titles of her articles, the greater the number of news
Ivahew [28]

Answer:

Positive.

Explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.

On the other hand, nonlinear function has a negative relationship and as such an increase in one variable (input variable) causes a decrease in the other variable (output variable) i.e the variables are inversely proportional.

This ultimately implies that, the graph of a nonlinear function is a curved line and whose direction is constantly changing

In this scenario, the relationship between numbers of adjectives and newspaper sales must be positive because the higher the amount of adjectives put in the titles of her articles, the greater the number of newspapers that would be sold on a particular day.
