An electronic firm finds that 4% of is defective.

this is not asking a question and i am not sure what the question you are asking is.

Step-by-step explanation:

out of every 100 only 96 are useful

96 can be delivered out of 100

5000 can be delivered out of (100x5000)/96 = 5208.33

as whole number next to it is 5209  

Now to verify

4% of 5209 = 4x5209/100 = 208.36 will be defective

or 209 rounded off

5209 - 209= 5000 ready to be delivered

So answer is 5209

Step-by-step explanation:

no this is a nonlinear negative

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.
