As fewer people buy bicycles, the demand for bicycle helmets will decrease and the price of a helmet will increase. The rise in the price of a bicycle helmet will increase the supply of bicycle helmets."

This statement is because

a. false; a decrease in demand for bicycle helmets does not increase the price of a bicycle helmet and an increase in the price of a bicycle helmet does not increase the supply of bicycle helmets.
b. true; when the demand for bicycle helmets increases, the supply of bicycle helmets increases so that the price of a bicycle helmet does not increase.
c. true; the increase in the price of a bicycle helmet increases the supply of bicycle helmets to eliminate the shortage.
d. false; the decrease in the demand for bicycle helmets creates a surplus and to eliminate the surplus, supply increases.
e. true; when the demand for bicycle helmets increases, the supply of bicycle helmets increases too so that no surplus occurs.

The correct answer is letter "A": false; a decrease in demand for bicycle helmets does not increase the price of a bicycle helmet and an increase in the price of a bicycle helmet does not increase the supply of bicycle helmets.

Explanation:

In economics demand and supply represents a basic concept to understand fluctuations of price and consumer and producer variations. When prices rise, demand raises and supply decreases. When prices drop, demand drops and supply increases. Demand has a direct relationship with the changes in price while supply has an inverse relationship with price.

Thus, if the demand for bicycle helmets decrease, the price of helmets will decrease. If there is an increase in the price of bicycle helmets there will be a decrease in the supply of bicycle helmets. The statement proposed in the case is false.

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
