Answer:
Vf = Vi % (1+0,112)ⁿ
Step-by-step explanation:
Vf: value of the company in t years
Vi: value of the company today (2009)
n: number of years after 2009
Let's do an example:
What is the value of the company in 2014? That would mean 5 years later.
Let's replace the data into the formula:
Vf = $9.220.000 % (1+0,112)⁵
Vf = $9.220.000 % 1,700293
Vf = $5.442.592,70 is the value of the company in 2014.
The answer or number that you are looking for is -6.4. You can get this by dividing 3 by 5 which is equal to 0.6. Next you would subtract 7 to reverse the act of having added it. This will give you -6.4 which is what you are looking for.
Answer:
a) Mean = 382.3 psi
Standard deviation = 20.8 psi
b) 392.7 psi
c) P(X<400)=0.8026
Step-by-step explanation:
a) The population mean can be estimated as equal to the mean of the sample, and the population standard deviation can be estimated from the sample standard deviation:


b) We start by searching for the z-value for the 95th percentile. This value is
z=1.645:

Then, the strength value below which 95% of all welds will have their strengths is:

c) We calculate the probability of X being equal or less than 400 as:

4.5h=6t/100
6t=100(4.5h)
t=100(4.5h)/6
t=75
