To get admitted to top universities, the applicant's sat (scholastic aptitude test) score must be on a very high side. in terms of concepts learned in mat201, this means that: question 9 options: a) the applicant's sat z-score has to be positive and large. b) the applicant's sat z-score has to be negative. c) the applicant's sat z-score has to be close to zero d) the applicant's sat z-score has to be close to one.

look a the sides they are perpendicular

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.
