Hey Guys, I am hoping you are having a BRILLIANT day. PLEASE help me with this question on reducing percentages and i would love for SOLVING out too! points to anyone who can show understanding.

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

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?

Write the slope intercept equation for line ab.
