Minneapolis has a population of 382,578, oakland has a population of 390,724 and wichita has a population of 382,368. which place could you round to so that the rounded populations of all three cities are different?

Step-by-step explanation:

Minneapolis has a population of 382,578

Oakland has a population of 390,724

Wichita has a population of 382,368

All three cities have 6 places of population.

Round off: If round off digit is more than or equal to 5 then it increases previous digit by 1 .

If round off digit is less than 5 then doesn't change in previous digit.

Round off all population to thousands.

First Round off the number 382,578 to thousands place

382,578 ⇒ hundreds digit is 5. So, thousands place digit will increase by 1

382,578 ⇒ 383,000

390,724 ⇒ hundreds digit is 7. So, thousands place digit will increase by 1

390,724 ⇒ 391,000

382,368 ⇒ hundreds digit is 3. So, thousands place digit will not change.

382,368 ⇒ 382,000

After round off the population:-

All three cities are different population.

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.

definitely a. the others have almost all data points on one side of the line.
