The form of quadratic representing the roots can be expressed as,
Where p and q are the roots of the equation.
The form which represents the zeroes of function h is,
Where 2 and -2 are the roots of the function h(x).
Thus, option (B) is correct.
Answer:
300838km^2
Step-by-step explanation:
Divide the total population by the population per kilometer squared
61070224/203
=300838.5419...
As the question askes for the approximate area, round the answer to the nearest kilometer squared
=300838km^2
A) 5 to be chosen among a Total : 10 Men + 8 Women
¹⁸C₅ = (18!)/(5!)(13!) = 8,568 groups of five
b) A must to have men and women. If so we have to deduct all groups of 5 that are all men and all group of 5 that are all women
Groups of 5 with only men: ¹⁰C₅ = 252
Groups of 5 with only women: ⁸C₅ = 56
So number of committees of 5 men and women mixed =
8568 - 252 - 56 = 8,260 committees
c) 3 Women and 2 Men:
⁸C₃ x ¹⁰C₂ = 2,520 groups of 3 W and 2 M
d) More women than men, it means:
3 W + 2 M OR (we have found it in c) = 2,520)
4 W + 1 M OR ⁸C₄ x ¹⁰C₁ →→→→ = 700
5 W + 0 M OR ⁸C₅ x ¹⁰C₀ →→→→ = 56
Total where W>M = 3,276 groups of 5 where women are at least 3
