Put the equation in standard form with a positive x coefficient y-2 = -2/5 (x-8)

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?

The measure of angle theta is 3 pi over 2. the measure of its reference angle is pi /

Write an equation with the solution x=20. the equation should have the variable on both sides, a fractional coefficient on the left side, and a fraction anywhere on the right side. show work
