Answer:

The proportion of people in your sample whose response is yes=40 people

Explanation:

<em>Step 1: Determine the statistical proportion that will say yes</em>

Proportion=40%=40/100=0.4

<em>Step 2: Determine the proportion in the sample that will say yes</em>

The proportion in the sample can be expressed as;

P=S×Z

where;

P=proportion in the sample

S=statistical proportion

Z=sample size

In our case;

P=unknown to be determined

S=40%=40/100=0.4

Z=100

replacing;

Proportion in the sample=0.4×100=40

The proportion of people in your sample whose response is yes=40 people

ddd [48]

In the year 2006, giant of the mining industry Xstrata purchased the Tintaya copper mine in Espinar, Peru. There has been a dispute between the community and the mine over issues including land rights,  pollution,  and social responsibility of the mining company.

According to many people , when Xstrata took over, the company did not abide by those arrangements which were made by the previous owner.

aalyn [17]

Answer:

2016: $300 million; 40%; $60 million

2017: $450 million; 60%; $90 million

Explanation:

Total costs:

= Costs incurred in 2016 + Costs incurred in 2017

= $240 + $360

= $600

In 2016:

Percent of total excepted costs:

= Costs incurred in 2016 ÷ Total costs

= $240 ÷ $600

= 0.4 or 40%

Revenue recognized:

= Percent of total excepted cost × Contract price

= 0.4 × $750 million

= $300 million

Income = Revenue recognized - Costs incurred in 2016

             = $300 million - $240 million

             = $60 million

In 2017:

Percent of total excepted costs:

= Costs incurred in 2017 ÷ Total costs

= $360 ÷ $600

= 0.6 or 60%

Revenue recognized:

= Percent of total excepted cost × Contract price

= 0.6 × $750 million

= $450 million

Income = Revenue recognized - Costs incurred in 2017

             = $450 million - $360 million

             = $90 million
