Which of the indicators on the chart above tell(s) us that Australia and New Zealand are highly developed countries?
ExtremeBDS [4]

Answer:

Answer: D

GDP per capita is a measure of a country's economic output that accounts for its number of people.

The unemployment rate is defined as the percentage of unemployed workers in the total labor force.

The infant mortality rate is the number of deaths under one year of age.

Given the above information, a country with a higher GDP would have a more stable economy aiding in growth. A lower unemployment rate would show a surplus of jobs indicating, once again, a steady and growing economy. Lastly, a lower infant mortality rate would show access to advanced medicine and a highly trained medical field. All three of these examples are indicators of a highly developed country.

As the price of gummy bears rises from $2. 60 to $3 , what are the price elasticities of demand of sugar-free gummy bears and of
NISA [10]

The price elasticities of demand of sugar-free gummy bears and of ordinary gummy bears is -0.8 and -2.3 respectively.

<h3>How to calculate price elasticity</h3>

Change in price of gummy bears = $2. 60 to $3

Elasticity of demand of sugar-free gummy bears =

[(273-379 / (273+379)/2] ÷ [(3.00-2.60)/(3.00+2.60) / 2]

= [-18/166] / [0.4/2.8]

= -0.10843373493975 / 0.14285714285714

= - 0.75903614457826

Approximately, -0.8

Elasticity of demand of regular gummy bears:

Sugar free = [(273-379) / (273+379)/2] ÷ (3.00 +2.60) / 2]

= [-106/326] / [0.4/2.8]

= -0.32515337423312 / 0.14285714285714

= -2.2760736196318

Approximately, -2.3
