Assume that interest rates on 20-year treasury and corporate bonds with different ratings, all of which are noncallable, are as follows:

t-bond = 7.72%
a = 9.64%
aaa = 8.72%
bbb = 10.18%

the differences in rates among these issues were most probably caused primarily by:

answer

a. real risk-free rate differences.
b. tax effects.
c. default risk differences.
d. maturity risk differences.
e. inflation differences.

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)
