En una dieta experimental para una persona, se determinó que el peso promedio "p" (peso en kilogramos) es una función lineal del número de días "d" donde 0 ≤ d ≤ 60.suponga que el peso promedio de una persona es de 95 kg al inicio de la dieta, y 30 días después fue de 85 kg. Determinar "p" como una función lineal de "d", y el peso promedio de una persona cuando ha transcurrido 10 días con la dieta.

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?
