Answer:
Step-by-step explanation:
In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. For example, the complex conjugate of 3 + 4i is 3 − 4i. In polar form, the conjugate of is.
Answer:
"6 out of 10 people" means the ratio of class:no_class is 6:4
990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.
99(6) = 594 ----------- probably class
99(4) = 396 ------------------ probably no class
Total = 990

Answer:
The answer to the first question is B.
The answer to the second question is C.
A plausible guess might be that the sequence is formed by a degree-4* polynomial,

From the given known values of the sequence, we have

Solving the system yields coefficients

so that the n-th term in the sequence might be

Then the next few terms in the sequence could very well be

It would be much easier to confirm this had the given sequence provided just one more term...
* Why degree-4? This rests on the assumption that the higher-order forward differences of
eventually form a constant sequence. But we only have enough information to find one term in the sequence of 4th-order differences. Denote the k-th-order forward differences of
by
. Then
• 1st-order differences:

• 2nd-order differences:

• 3rd-order differences:

• 4th-order differences:

From here I made the assumption that
is the constant sequence {15, 15, 15, …}. This implies
forms an arithmetic/linear sequence, which implies
forms a quadratic sequence, and so on up
forming a quartic sequence. Then we can use the method of undetermined coefficients to find it.
