You know that 14/32 are boys. Divide this out and you get 0.4375, move the decimal two places to the right and you get 14/32 = 43.75%. The percentage of boys plus girls must equal 100%, so knowing that is the percentage of boys, 100% minus 43.75% must equal the percentage of girls. 100% - 43.75% = 56.25% so 56.25% is the percentage of girls in the class.
4/5 is the answer.
The formula is y=mx+b, where m is the slope
Answer:
2

The key piece of information for these questions is the Fundamental Theorem of Algebra, which states that a degree n polynomial has n complex roots. A complex root can be either real or imaginary.
First question, regarding the polynomial y = x^3 - 3x^2 + 16x - 48:
We know there is one real root, the x-intercept.
Since it's a third degree polynomial, there are three complex roots in total.
Therefore, there is one real root and two imaginary roots.
Answer is B
Second question:
You probably can guess the answer, now that you know the Fundamental Theorem of Alegebra:
There are 3 real zeros, each with multiplicity one, meaning each root only happens once. It's a 5th degree polynomial, so there are a total of 5 roots, implying 2 imaginary roots.
Answer is C) 3 real and 2 imaginary zeroes.
