In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000

Answer the following questions using wolframalpha as demonstrated above. be sure to include all graphs you generate. a $120,000 home mortgage for 30 years at 71% has a monthly payment of $839.06. part of the monthly payment is paid toward the interest charge on the unpaid balance, and the remainder of the payment is used to reduce the principal. the amount that is paid toward the interest is: (see attached)and the amount that is paid toward the reduction of the principal is: (see attached 2)in these formulas, p is the size of the mortgage, r is the interest rate, m is the monthly payment, and t is the time (in years). note that t is a variable, while the other values represent constants. a) use wolframalpha to graph each function in the same coordinate plane (like the demonstration).b) in the early years of the mortgage, is the larger part of the monthly payment paid toward the interest or the principal? approximate the time when the monthly payment is evenly divided between interest and principal reduction. c) repeat parts a and b for a repayment period of 20 years (m = $966.71). compare your results to the ones you obtained in a and b.
