Answer:
$0.013
0.010724
Explanation:
Given that :
Mean, m = 36500
Standard deviation, s = 5000
Refund of $1 per 100 mile short of 30,000 miles
A.) Expected cost of the promotion :
P(X < 30,000)
Using the Zscore relation :
Zscore = (x - m) / s
Zscore = (30000 - 36500) / 5000
= - 6500 / 5000
= - 1.3
100 miles = $1
1.3 / 100 = $0.013
b. What is the probability that Grear will refund more than $50 for a tire?
100 miles = $1
$50 = (100 * 50) = 5000 miles
Hence, more than $50 means x < (30000 - 5000) = x < 25000 miles
P(x < 25000) :
(25000 - 36500) / 5000
-11500 / 5000
= - 2.3
P(z < - 2.3) = 0.010724 (Z probability calculator)
Answer:
C. workers with more years of formal schooling are less likely to be affected by ability, effort, and chance.
Explanation:
The <em>signalling theory in education</em> tells us that employees send "signals" to their employees regarding their education. In other words, employers are willing to pay higher wages to employees with additional years of formal schooling.
This means these qualified workers have their wage primarily defined by their education level, which does not always reflect their true skill-set (the output of ability and effort).
Answer:
3482.12
Explanation:
Net present value is the present value of after-tax cash flows from an investment less the amount invested.
NPV can be calculated using a financial calculator
Cash flow = net income + depreciation = 16,200 + 3300 = 35,700
($56,100 - $7500) / 3 = 16,200
Cash flow in year 0 = 56,100
cash flow in year 1 and 2 = 35700
cash flow in year 3 = 35,700 + 7500
i = 5%
NPV =
Answer: External secondary data
Explanation:
External secondary data are data gathered and saved by someone or a body that is not part of one's organization. Sources of External secondary data includes published materials, computerised databases and syndicated services.
Note that how difficult or easier it will be getting a secondary data will depend on the methods used in storing and indexing it.
Answer:
The correct answer is letter "E": Perceptual defense.
Explanation:
In psychology, perceptual defense refers to the suppression of a stimulus that represents a threat or an uncomfortable situation for an individual. Those inputs are distorted somehow by the individual to reject the unpleasant feeling so that the person does not feel that bad because of it. In such a way, the brain works as a defense mechanism able to distort information to mitigate the effects in the behavior produced by the stimulus.
