Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:



Therefore, there are 10 ways we could arrange 3 blue marbles.
Answer:
The correct option is d. $ 785
Step-by-step explanation:
Since,

Where,
C = Annual coupon payment,
FV = Face value,
M = Maturity in years,
YTM = yield to maturity,
Here,
FV = $ 1,000,
C = 7% of 1000 =
= 70,
M = 20 years,
YTM = 9.4% = 0.094,
By substituting the values,

= $ 785.3454 ( Using calculator )
≈ $ 785
Hence, OPTION d. is correct.
Recall the Maclaurin expansion for cos(x), valid for all real x :

Then replacing x with √5 x (I'm assuming you mean √5 times x, and not √(5x)) gives

The first 3 terms of the series are

and the general n-th term is as shown in the series.
In case you did mean cos(√(5x)), we would instead end up with

which amounts to replacing the x with √x in the expansion of cos(√5 x) :
