Subtract: 7 9 16 - 4 2 4 a) 3 7 12 b) 3 1 16 c) 3 7 20 eliminate d) 3 11 12

Use the elimination method to solve the system of equations -x+5y=-4 and 4x+3y=16

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?

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x
