Answer:

The surface area of the cube is 96 squared unit.

Explanation:

The surface area of a cube is the addition of the area of each surfaces. The surface net of the cube illustrates that it has 6 squares of 4 unit length each.

So that,

 Area of a square = length × width

But, length = width

⇒ Area of a square  = (length)^{2}

                              = (4)^{2}

                              = 16

Area of one of the squares of the cube is 16 squared unit.

Surface area of the cube = number of squares × Area of one of the squares of the cube

                                          = 6 ×16

                                          = 96 squared unit

The surface area of the cube is 96 squared unit.

A marketing company wants to estimate the proportion of consumers in a certain region of the country who would react favorably t
Sindrei [870]

The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271

Explanation:

When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-

n=0.25(\frac{z^{*} }{E} )^{2}

where E = Margin of error.

z* = Critical z-value.

As per given , we have

E = 5%=0.05

Confidence level = 90%

The critical value of z at 90% is 1.645  (By z-table)

Put all values in the formula , we get

n=0.25(1.645/0.05)²

n=0.25(32.9)²

n=270.6025≈271

Thus, the minimum sample size needed = 271

Hence , the correct answer is 271 .

Describe at least four factors that affect the demand for a particular commodity.
MrMuchimi

Answer with Explanation:

There are so many factors affecting the demand for a particular commodity. Four of these are: the price of the complements, the income of buyers, changes in trend and advertisements.

1. The price of the complements - Some commodities are complementary with each other, just like cars and gas. If the <em>price of cars decreases</em>, then many people will purchase their own cars, which also follows that <em>the demand for gas will increase.</em>

2. The income of buyers - If the income of a person increases, then he will most likely purchase a particular commodity because he can afford it and has an extra money to purchase goods.

3. Changes in trend - Many people purchase goods because they're on trend. For example, if flare pants are fashionable this year, then the demand for it will increase. Once they're no longer on trend, the demand will drop.

4. Advertisements - The more advertisements a company spends on, the more likely buyers will purchase a specific commodity.

Which would be an example of sustainable development? a. Current use of fossil fuels in the U.S. b. Heap-leach extraction of gol
Setler [38]

Answer:

The correct answer is letter "D": Development of brownfields in urban areas.

Explanation:

In urban planning, sustainable development refers to continuous activities that can be performed during extended periods of time. They are the result of repeated patterns of individuals who, sometimes unconsciously, provoke more and more individuals to repeat their actions.

Under such a scenario, <em>the development of brownfields in urban areas is the result of building more department complexes in the cities because of the increasing need for renting and selling houses as a result of the increasing population growth.</em>
