In Joe’s neighborhood, there is a 20% chance of finding a parking spot on the street after 5 p. m. Joe always arrives home from work after 5 p. m. each weeknight. Last week, Joe found a parking spot on the street on 3 out of 5 days during the week. Was this an unusual occurrence or could Joe expect this to happen again sometime soon? Describe how you could design a simulation to represent the situation and answer the question: You do not need to conduct the simulation.

Joe could drive up to the street earlier, before work, and reserve, or put cones on a parking spot, and then he will be there in time to move the cones and park there.

not solvable

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.
