A teacher wanted to fairly choose three students from a class of 23 to raise the school's flag. She assigned each student a two-digit number from 01 to 23.
(Let's consider "01", "02", etc. to be two-digit numbers.)
She then selected the following line from a random number table.
21215 91791
76836
58678
87054
3168793205
Starting from the left, she used the line above to form two-digit numbers as follows.
21 21 59
LIMI
Using this new list and starting from the left she chose three two-digit numbers from 01 to 23.
she skipped numbers she had already chosen, the number 00, and numbers greater than 23.
The students who were assigned these two-digit numbers were chosen
Which three students did the teacher choose?

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.
