Marge drove 220 miles at an average speed of 55 miles per hour. How many hours did it take her to drive that far? Oh

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

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?

What is the equation of the line that is parallel to the line with the equation y= -3/4x +1 and passes through the point (12,-12)
