Answer: 0.75

Explanation:

Mean(μ) = 300

Standard deviation(σ) = 20

Find the z-score of a person who scored 315 on the exam ;

Raw score (x) = 315

Z = (raw score - mean) ÷ standard deviation

Z = (x - μ) ÷ σ

Z = (315 - 300) ÷ 20

Z = 15 ÷ 20

Z = 0.75

The capital-to-labor ratio is:Question 40 options:a) a key element in decreasing real wages.b) high in rich countries.c) the rat
andrezito [222]

Answer:

b) high in rich countries.

Explanation:

Capital-to- labour ratio measure the degree of capitalisation of an economy.

Labour is the service that is given by workers in exchange for salaries in the production process.

Capital is the long term input that is put into the manufacturing process, usually in the form of machinery or systems that automate production.

Capital-to-labour ratio= Total capital/ Total labour

Rich countries have a high level of capitalisation of their production process, where a lot of activity is automated. So capital is high and labour input is low. This results in a high capital-to-labour ratio.

On the other hand poor countries are more labour inensive, so their capital-to-labour ratio is low.

A car was purchased for $4500 down and payments of $375 at the end of each month for 5 years. Interest is 9.72% compounded month
agasfer [191]

Answer:

$21,080.2

Explanation:

The price of the car will be the down-payment plus the future value of 375 paid each month for 5 years compounded monthly at 9.72%.

The formula for calculating future value is

PV = P ×  1 − (1+r)−n

  r

PV is $350

r is 9.72 % or 0.0972 % per year or 0.0081

t is five year or 60 months

FV = 350 x (1-(1+0.0081)-60

  0.0081

Fv =350 x 1-0.61628715419

  0.0081

FV =350 x( 0.38371284581/0.00810

FV =350 x 47.371956

FV =16,580.20

The value of the car = $4500 + 16,580.20

=$21,080.2
