Based on the sample results of the population the percentage of population that prefers reading a hard copy i fht e digital copy is 4, the hard copy is 21 and n equas 25 is 84%

Step-by-step explanation:

From the above question we know that .

Total number of population, n = 25

Number of people who prefer to read a digital copy = 4

Number of people who prefer to read a hard copy = 21

As per the question we need to find out the percentage of population who prefer to read hard copy.

So we use the formula

Percent of population preferring hard copy = Hard copy/Total*100

Percent of population that prefers hard copy = 21/25*100

Percent of population that prefers hard copy = 0.84 × 100 = 84%

So , the percent of population who prefers to read a hard copy are about 84%.

The volume of a cube is 27n^27 cubic units. What is the length of one side of the cube?

elena-14-01-66 [18.8K]

The volume of a cube (V) is given in terms of its side length (s) as

... V = s³

You have

... 27n²⁷ = s³

You may recognize that 27 = 3³, so this can be written as

$3^3\cdot n^{3\cdot 9} = \left(3n^{9}\right)^{3}=s^{3}\\\\3n^{9}=s\qquad\mbox{taking cube roots}$

This result matches your second selection

... 3n⁹ units
