Answer:

Option a

Step-by-step explanation:

The Box & Whisker chart displays the spread and skewness in a batch of data through its five-number summary: minimum, maximum, median, upper and lower quartiles. It is used:

For easy understanding of the distribution of a dataset

To know the skewness if any

To find out outliers

Pie chart can be replaced by bar chart a. angle judgments are replaced by area judgments in a bar chart.

Butoxors [25]

Answer:

Sleep debt

Step-by-step explanation:

Also called sleep deficit, sleep debt can be likened to a deficit in the bank such as a loan that must be repaid. The deficit accumulates and will have to balanced or there would be mental or psychological effect on the affected person. Research by The national sleep foundation requires Americans to sleep at least 7.1 hours per day.

There two types of sleep deprivation or sleep deficit: partial sleep deprivation and total sleep deprivation. In Partial sleep deprivation, the person may not get enough sleep per day example not up to 7.1 hours per day. Total sleep deprivation means that the affected person does not sleep for up 24 hours ie a full day.

Find the volume of the sphere. express your answer in term of Pie​
IceJOKER [234]

Answer:

\large\boxed{36\pi}

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

R - radius

We have R = 3 ?. Substitute

V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3}\pi(27)=(4)\pi(9)=36\pi

If the radius is 30, then the volume is:

V=\dfrac{4}{3}\pi(30^3)=\dfrac{4}{3}\pi(27,000)=(4)\pi(9,000)=36,000\pi

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.

Therefore the volume:

V=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3,375)=(4)\pi(1,125)=4,500\pi

The main show tank has a radius of 60 feet and forms a quarter sphere where the bottom of the pool is spherical and the top of t
svetlana [45]

The given radius is = 60 feet

The volume of the sphere is given by = \frac{4}{3} \pi r^{3}

So we will find the volume of the sphere using radius as 60 and pi as 3.14

Volume = \frac{4}{3}*3.14*60*60*60 = 902059.20 cubic feet

As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.

So volume of quarter sphere = \frac{902059.20}{4}

= 225514.80 cubic feet

And rounding this to nearest whole number we get 225515 cubic feet as the answer.
