Not respond with i don't know or anything but with the answer just for the ! the average test score a of five test scores t 1, t 2, t 3, t 4, and t 5 can be computed by the formula shown below.

a=t 1+t 2+t 3+t 4+t 5/(over)5

if a student has test scores of 88, 71, 80, and 72, what score does she need on the fifth test so that her five-test average is 76?

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.

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet
