Problem iii (15 pts) the weights of a certain population of young adult females are approximately normally distributed with a mean of 132 pounds and a standard deviation of 15. find the probability that a subject selected at random from this population will weigh: more than 155 pounds.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

1/4 of 84 = 84÷4= 21
