Carrie predicts she will collect 50 cans for the food drive. If Carrie actually collects 70 cans, what is Carrie's percent error? Round your answer to the nearest tenth of a percent.

Carrie's percent error was 28.6%

Step-by-step explanation:

Step 1; From the given data Carrie predicted that she would have lesser than she actually got. She estimated that she would collect 50 cans when she actually got 70 cans.

Step 2; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.

% error = (difference in values / actual value) × 100

Difference in values = 70 - 50 = 20

Claire's % error = (70 - 50)/ 70 × 100 = 20/70 × 100 = 0.28571 × 100 = 28.571%.

The 28.571% is rounded off to 28.6%

answer: do we write it

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.
