Like any other polynomial, you judge the number of solutions by the highest degree of the polynomial. This is a second degree polynomial so it has 2 solutions. They are x = +[sqrt(cos x)] and x = - [sqrt(cos x)]. If you graph those on a calculator the positive portion of the graph is above the x axis and the negative portion is below the x axis. It's really cool looking. You should graph it to see.
Since a cube has 6 sides, we can divide 294 by 6, so we have the area of one side. Since it is a cube, we can just square root that, and you get 7 cm.

Answer:
A
Step-by-step explanation:
A trail would consist of three random digits.
The problem asks for the probability that it will take at least a sample of four to find one person with brown hair. This implies that the first three people do not have brown hair. Therefore, a trial would consist of three random digits. A success is none of the three digits are 0, 1, 2, or 3. For example, 675 would be a success and a failure would be 792.
