Answer:
f(x) = 54(two-thirds) Superscript x minus 1
Step-by-step explanation:
Given that:
First peak : 36 / 54=2/3
Second peak : 24 / 36 = 2/3
The common ratio here is 2/3 ; which mean each bounce height is 2/3 of previous height
Modeling this using geometric progression :
An=a1r^(n-1)
An = nth term of a geometric progression
a1=first term
r=common ratio = 2/3
n = nth term
a1=54
Substituting into the above formular :
An=54(2/3)^(n-1)
Answer:
X is the GPA
Y is the Salary
Standard deviation of X is 0.4
Standard deviation of Y is 8500
E(X)=2.9
E(Y)=47200
We are given that The correlation between the two variables was r = 0.72
a)


So, slope = 15300
Intercept = 2830
So, equation : 
b) Your brother just graduated from that college with a GPA of 3.30. He tells you that based on this model the residual for his pay is -$1880. What salary is he earning?

Observed salary = Residual + predicted = -1860+53320 = 51440
c)) What proportion of the variation in salaries is explained by variation in GPA?
The proportion of the variation in salaries is explained by variation in GPA = 
Answer:
The cost of Ningbo Shipping Preferred stock is 12.40%
Step-by-step explanation:
In this question, we are asked to calculate the cost of Ningbo shipping Preferred stock.
To calculate this, we make use of the following mathematical relation;
The cost preferred stock Kp = Annual dividends/ Issued price-Cost of Issuing
From the question, we identify the following;
Issued price = $125
Annual dividend = $15
Cost of Issuing = $4
Inserting these into the formula we have;
Kp = $15/$125 - $4 = 12.40%
This means that Cost of Ningbo shipping preferred stock is 12.40%
