vazorg [7]

Solution -

A student who was skeptical about this value decided to conduct a survey by randomly sampling 36 students. On average, the sampled students slept 6.6 hours per night.

The sample mean is the average of the 36 sampled students, which is 6.6 hours. So 6.6 represents the <u><em>sample mean.</em></u>

College newspaper stated that college students get an average of 7 hrs of sleep each night.

The claimed population mean is the stated average from the newspaper article, which is 7 hrs.  So 7 represents the <u><em>claimed population mean.</em></u>

dalvyx [7]
That would be 0.99 because the hundredth place would be the second number after the decimal and since the number in the thousandths place is 0, the number in the hundredths place doesn't need to change.

Which of the following statements is true for the logistic differential equation?
solong [7]

Answer:

All of the above

Step-by-step explanation:

dy/dt = y/3 (18 − y)

0 = y/3 (18 − y)

y = 0 or 18

d²y/dt² = y/3 (-dy/dt) + (1/3 dy/dt) (18 − y)

d²y/dt² = dy/dt (-y/3 + 6 − y/3)

d²y/dt² = dy/dt (6 − 2y/3)

d²y/dt² = y/3 (18 − y) (6 − 2y/3)

0 = y/3 (18 − y) (6 − 2y/3)

y = 0, 9, 18

y" = 0 at y = 9 and changes signs from + to -, so y' is a maximum at y = 9.

y' and y" = 0 at y = 0 and y = 18, so those are both asymptotes / limiting values.
