Answer:
probability of a reliable performance = 19/20
Explanation:
If a new battery has just been installed, then the chances of failure are only contributed by the faulty microchip, which has a failure rate of 1 in 20 hours.
Therefore in 1 hour, the probability that the laptop will perform reliably is calculated as follows:
Chances of failure = 1 in 20
20 hours = 1 chance of failure
∴ 1 hour = 1/20 chance of failure
1/20 = 0.05 chance of failure
Now, let us express 0.05 as fraction:
0.05 = 5/100
Therefore in 1 hour, there is a 5 in 100 chances of failure.
But we are asked to find the probability that the laptop will perform reliably. This is simply done by finding the difference between the total chances of occurrence (100) and the chances of failure (5)
∴ Probability of reliable performance in one hour = (100 - 5) / 100
= 95/100
95/100 = 19/20
Answer:
Hugh's statement is an attempt to reduce his frustration about buying the product at a more expensive price.
Explanation:
Human beings always try to find a reason to justify their actions, even if that particular action was a bad one.
Hugh bought a calculator for $125 from one store and the next week, he saw the same calculator being advertised for a significantly lower amount. He felt cheated and he immediately blamed himself for being cheated when there was a better deal out there. As a way to make himself feel better about the ordeal, he tells himself that the product quality from the second store is always known to be of an inferior quality.
This is a defence mechanism to cover or try to hide our frustrations and anger at things not going our way so we invent something that will make us immediately feel better about ourselves and our decision.
Answer: $66.25
Explanation:
What should the per unit selling price be to make a 25% profit this year?
First, we'll calculate the total cost which will be:
= $100,000 + $5000(33)
= $100,000 + $165,000
= $265000
%profit = 100(revenue - cost)/ cost
25% = 100(revenue - 265000)/265000
Therefore, revenue will be:
265000(1 + 25%) = 331250
265000(1.25) = 331250
Revenue = $331250
Selling price per unit will be:
= $331250/5000
= $66.25/unit
Answer: Option B
Explanation: Earnings per share is calculated by dividing net income available to common shareholders with the weighted average number of shares.
Deduction of preferred dividends from net income is done only when dividends are declared by the entity, otherwise not. Preference shareholders have priority over common shareholders in case of dividends, so it will result in reduction of earnings to common shareholders but only when the dividends are declared and distributed.
Market for new issues of securities is Primary Market and Market for already-existing securities is Secondary Market.
What is Secondary Market?
Investors can acquire and sell securities they already possess on the secondary market. Although stocks are also sold on the main market when they are originally issued, it is what most people refer to as the "stock market."
Therefore,
Market for new issues of securities is Primary Market and Market for already-existing securities is Secondary Market.
