What is volume of thi shown below?

Answers

Answer:

13613.46 cm^3

Step-by-step explanation:

Height of the conical top= 25 cm

Diameter of the conical top = 20 cm

Radius of the conical top = 10 cm

[tex]We\ know\ that,\\Volume\ of\ a\ cone\ = \frac{1}{3}\pi r^2h\\Hence,\\Volume\ of\ the\ conical\ top\ = \frac{1}{3}\pi 10^2*25 = \frac{1}{3} \pi 100*25\\= 833.3\pi\ cm^3[/tex]

Height of the cylindrical base = 35 cm

Diameter of the cylindrical base = 20 cm

Radius of the cylindrical base = 10 cm

[tex]We\ know\ that\ ,\\Volume\ of\ a\ cylinder\ = \pi r^2h\\Hence,\\Volume\ of\ the\ cylindrical\ base = \pi* 10*10*35\\=3500\pi\ cm^3[/tex]

[tex]Hence,\\Volume\ of\ the\ given\ figure\ = Volume\ of\ the\ conical\ top\ + Volume\ of\ the\ cylindrical\ base\ \\Hence,\\Volume\ of\ the\ given\ figure\ =833.3\pi +3500\pi \\=(3500+833.3)\pi \\=4333.3\pi \\=13613.46 cm^3[/tex]

Answer:

13,614cm³

Explanation:

There are 2 solid shapes in the object;

A cylinder and A cone

Volume of the cylinder = πr²h

Volume of the cone is 1/3πr³h

h of cone = 25cm

h of cylinder = 35cm

d of the cylinder and cone = 20cm

r = d/2 = 10cm

Volume of the cylinder = πr²h

= π(10)²×35 = 10,996cm³

Volume of the cone = 1/3πr²h

= 1/3π(10)²×25 = 2618cm³

Therefore the total volume of the object above =

Volume of the cylinder + Volume of the cone =

10,996cm³ + 2618cm³ = 13,614cm³

A school psychologist at a large high school took a random sample of 16 students and asked how much sleep they get on a typical weekend night. The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours

Answers

Answer:

8.75 +/- 0.657

Step-by-step explanation:

The 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617

What is confidence interval?

A confidence interval is a range around a measurement that conveys how precise the measurement is.

Given that, The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours, the confidence level value is 90%

confidence interval = x ± z·s/√n

= 8.75±1.645·1.5/√16

= 8.75±0.617

Hence, the 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617

Answers:

It is (18,9).

It is (9, 18).

There are infinitely many solutions.

There is no solution.

There are infinitely many solutions because the equations equal each other. The equation for line R is double the equation for line M; therefore, they are the same. If you graph it the line would be the exact same.
