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:
-2
Step-by-step explanation:
The volume of cone formula is 1/3 times pi times radius^2 times height. So in this case the formula which numbers substituted in would be 1/3 times pi times 8^2 times 12. The final answer would be 804.2477 and if rounded it would be 804.2 m^2
A dime is a ten cent coin while a quarter is a 25 cent coin. The total of the money should be $8.40. Let x be the number of dime and y be the number of quarter. The equation that would best represent the given problem is,
0.1x + 0.25y = 8.40
x + y = 45
The values of x and y are 19 and 26, respectively. Thus, there are 19 dimes and 26 quarters.
