Answer:
[ $591.08, $1101.32 ]
Explanation:
Given:
Sample space = 200
Mean price = $846.20
Standard deviation, σ = $1,840.80
Confidence level = 95%
Now,
Confidence interval is given as:
⇒ Mean ± 
here, z value for 95% is 1.96 from the standard z table
Thus,
Confidence interval
⇒ $846.20 ± 
or
⇒ $846.20 ±
or
⇒ $846.20 ± 255.12
or
⇒ [ $846.20 - 255.12, $846.20 + 255.12 ]
or
⇒ [ $846.20 - 255.12, $846.20 + 255.12 ]
or
⇒ [ $591.08, $1101.32 ]

Explanation:
Given the data:
x___ f(x)
10__ 0.05
20__0.10
30__0.10
40__0.20
50__0.35
60__0.20
a. Is this probability distribution valid?
Yes
Σf(x) = (0.05 + 0.10 + 0.10 + 0.20 + 0.35 + 0.20) = 1
0≤f(x)≤1
b. What is the probability MCC will obtain more than 30 new clients
X = 40 + x = 50 + x = 60
0.20 + 0.35 + 0.20 = 0.75
c. What is the probability MCC will obtain fewer than 20 new clients
x = 10
f(x) = f(10) = 0.05
d)Compute the expected value and variance of x.
Expected value (E(x)) :
Σ(x * f(x))
= (10*0.05) + (20*0.1) + (30*0.1) + (40*0.2) + (50*0.35) + (60*0.2)
= 43
Σ(x * E(x))² * f(x)
= (10 - 43)^2 * 0.05 + (20 - 43)^2 * 0.1 + (30 - 43)^2 * 0.1 + (40 - 43)^2 * 0.2+ (50 - 43)^2 * 0.35 + (60 - 43)^2 * 0.2
= 201
Answer:
C. impose barriers to entry with a copyright, which allows only the government to supply a good or service.
Explanation:
- The oligopolies is a market or industry where there exist small but large sellers and hence form an market competition and hence lead to higher prices to the consumers. As they have their market structures. Entry barriers include high investment and strong consumer liabilities.'
- Thus governments can set barriers to entry of these firm as to market only those goods and services that the government recommend fit for the sales
Answer:
0.0210
Explanation:
The computation of the weight of the preferred stock is shown below:
Particulars Shares Price Value ( Shares × Price) Weight ( Value ÷Total value)
Equity 10,800 $42 $4,53,600 0.4179
Preferred Stock 245 $93 $22,785 0.0210
Bonds 580 $1,050 $6,09,000 0.5611
Total value $1,085,385
for computing the weight we simply divide the value of the preferred stock with the total value
Life expectancy is about 75 years.
One third:
75 : 3 = 25
So one generation is about 25 years.
2,000 : 25 = 80
Answer:
Approximately 80 generations have passed during the last 2,000 years.
