Ebra IV Advanced Algebra A-CR Which polynomial function has a leading coefficient of 2, root-4 with multiplicity 3, and root 10 with multiplicity 1?
Of(x) = 2(x – 4)(x-4)(x - 4)(x + 10)
Of(x) = 2(x + 4)(x + 4)(x + 4)(x - 10)
Of(x) = 3(x – 4)(x - 4)(x + 10)
Of(x) = 3(x + 4)(x + 4)(x - 10)

Find the value of the variable and the length of each secant segment.

Ineed to know the answer to this algebra question.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
