point q is plotted on the coordinate grid. point p is at (40, −20). point r is vertically above point q. it is at the same distance from point q as point p is from point q. which of these shows the coordinates of point r and its distance from point q?

1) point r is at (−10, −10), a distance of 30 units from point q
2) point r is at (−10, −30), a distance of 50 units from point q
3) point r is at (−10, 30), a distance of 50 units from point q
4) point r is at (−10, 10), a distance of 30 units from point q

Adifferent website gives the cost for the first train as £56.88 and the second train as £20.11 with a £9.50 charge for cycle storage for the whole trip. how much would the journey cost you?

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?
