In the following function defined by an equation in the form y = a x squared + b x + c, identify the values of a, b, and c. y = 5 x squared + 2 x minus 1

The vertices of a triangle are a(7,5), b(4,2), c(9,2). what is m

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

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?
