A certain reality TV show lost a total of 9{,}0009,0009, comma, 000 viewers over the past 333 months. It lost the same number of viewers each month. The following equation describes this situation. \quad -9{,}000\div 3 = -3,000−9,000÷3=−3,000minus, 9, comma, 000, divided by, 3, equals, minus, 3, comma, 000 What does -3{,}000−3,000minus, 3, comma, 000 tell us? Choose 1 Choose 1 (Choice A) A There are 3{,}0003,0003, comma, 000 fewer people watching the show compared to three months ago. (Choice B) B The total change in the number of people watching the show is -3{,}000−3,000minus, 3, comma, 000. (Choice C) C None of the above

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

b

step-by-step explanation:

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.
