Visitors to your website are asked to answer a single survey question before they get access to the content on the page. among all of the users, there are two categories: random clicker (rc), and truthful clicker (tc). there are two possible answers to the survey: yes and no. random clickers would click either one with equal probability. you are also giving the information that the expected fraction of random clickers is 0.3. after a trial period, you get the following survey results: 65% said yes and 35% said no. what fraction of people who are truthful clickers answered yes?

the answer

b. they are parallel and will never intersect.

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.

what level of math? also i don't need to be paid if i can you.
