Correct Answer: D. kolanut

Correct Answer: C. 40

Explanation

x\(^3\)y\(^2\) in (x-2y)\(^5\)

n = 5, r = 3, p = x, q = -2y

5C\(_3\) * x\(^3\) -2y\(^2\)

5C\(_3\) = \(\frac{5!}{[5-3]!3!}\)

\(\frac{5*4*3!}{2! 3!}\) → \(\frac{5*4}{2}\)

5C\(_3\) = 10

: 5C\(_3\) * x\(^3\) -2y\(^2\) = 10 * x\(^3\) 4y\(^2\)

40x\(^3\)y\(^2\)

the coefficient is 40

Correct Answer: D) combat economic and financial crimes in Nigeria

Explanation

Option A says that the EFCC was established to arrest, detain and prosecute corrupt state governors and legislators. While this may be one of the roles of the EFCC, it is not the main reason why the commission was set up.

Option B says that the EFCC was established to arrest and trial corrupt politicians. This is similar to Option A, and while it may be one of the roles of the EFCC, it is not the main reason why the commission was set up.

Option C says that the EFCC was established to assist the World Bank in monitoring economic projects in Nigeria. This is not correct because the EFCC is not involved in monitoring economic projects in Nigeria, and it was not established to assist the World Bank.

In conclusion, the correct answer to the question is Option D, which says that the EFCC was established to combat economic and financial crimes in Nigeria. This means that the EFCC investigates and prosecutes individuals who commit financial crimes in Nigeria.
