colin surveyed 12 teachers at his school to determine how much each person budgets for lunch. he recorded his results in the table. what does the relationship between the mean and median reveal about the shape of the data? the mean is less than the median, so the data is skewed left. the mean is more than the median, so the data is skewed right. the mean is equal to the median, so the data is symmetrical. the mean is equal to the median, so the data is linear.

1 is c

2 is a

3 is a

step-by-step explanation:

c

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.
