What is the upper and lower quartile of this data set? 15, 19, 20, 25, 31, 38, 41

Lower quartile = 19 and Upper quartile = 38.

Step-by-step explanation:

Since we have given that

15, 19, 20, 25, 31, 38, 41

Since they are arranged in increasing order.

We need to calculate the upper and lower quartile of this data set:

Number of data = 7

which is an odd number.

We have to divide it into lower half and upper half excluding the central value to calculate lower and upper quartile.

Since central value = 25

So, Lower half includes : 15,19,20

Upper half includes : 31,38,41.

So, Median of lower half is known as lower quartile.

Median of upper half is known as upper quartile.

Hence, Lower quartile = 19

Upper quartile = 38.

answer: i believe its b. if you sound out the sentences that sounds wrong.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
