Answer:
The function that would determine the cost in dollars, c(z), of mailing a letter weighing z ounces is (0.46 + 0.20z)
Explanation:
Weight of the letter = z ounces (z is an integer greater than 1)
cost to mail a letter weighing 1 ounce = $0.46
cost to mail an additional ounce = $0.20
cost to mail z additional ounces = z × $0.20 = $0.20z
Total cost of mailing a letter weighing z ounces = $0.46 + $0.20z
Therefore, cost function, c(z) = 0.46 + 0.2z
Answer: $20,478.78
Explanation:
In 14 years the investment will be,
Gold
10,000/2 = 5000
Then use the compound interest formula
5000 * (1+0.07)^ 14 = $12,892.67
For Certificates of Deposits.
Use the Compound interest formula
Rate and period are in years. Convert to semi annual basis.
3%/ 2 = 1.5%
14 * 2 = 28 periods
= 5000 ( 1+ 0.015) ^ 28
= $7,586.11
Add both
=$12,892.67 + $7,586.11
= $20,478.78
Some of the social factors that have led to unemployment in South Africa amongst the youth are:
- High population growth.
- High poverty rates.
As a result of high population growth, the number of youth in South Africa has increased to a point where getting jobs for all of them is quite difficult.
High poverty rates also mean that a lot of the youth are unable to afford a tertiary education which means that they are unable to get the qualifications needed for a job.

Answer:
D) Stock prices of companies that announce increased earning in January tend to outperform the market in February.
Explanation:
The above is consistent with the Efficient Market Hypothesis. All others are a direct contravention.
<em>The efficient market hypothesis (EMH), also known as the efficient market theory, is a hypothesis that states that the prices of shares contain all information and that consistent alpha generation is impossible.</em>
According to the hypothesis, stocks always trade at their fair value on exchanges, making it impossible for investors to purchase undervalued stocks or sell stocks for inflated prices.
This means that it should not be possible to outperform the overall market through professional stock selection or market timing.
The only way according to EMH that an investor can obtain better returns is by purchasing riskier investments.
By implication, this also means that it is not possible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.
You would note that in the option D, earning (which is a key driver for demand of stock) is announced in one month. The natural reaction would be for the demand for that stock to surge in the next month.
