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 .
<u>Total number of population, n = 25</u>
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
<u>Percent of population preferring hard copy = Hard copy/Total*100</u>
<u></u>
Percent of population that prefers hard copy = 21/25*100
Percent of population that prefers hard copy = 0.84 × 100 = 84%
<u>So , the percent of population who prefers to read a hard copy are about 84%.</u>

Answer:
1/4x -3
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y =4x+12
Exchange x and y
x = 4y+12
Solve for y
Subtract 12 from each side
x-12 = 4y+12-12
x-12 = 4y
Divide by 4
(x-12)/4 = 4y/4
The inverse is
1/4x -3
