One way to do this is to use ratios
another way is to graph it

if you use ratios then
1:25=5:125
1/25=5/125
1/25=1/25
therefor theya re in same ratios
(x,y)=(1,25)
find (3,y)
1:25 =3:y
1/25=3/y
multiplyh both siddes by y
y/25=3
multiply both sides by 25
y=75
the point is (3,75)

Based on the sample results what percent of the population prefers reading a hard copy? Digital copy:4 Hard copy:21 n=25 (A)-abo
vodka [1.7K]

Answer:

C-about 84%

Step-by-step explanation:

We are given 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

It is required to find out the percent of population who prefer to read hard copy.

So, we have,

Percent of population preferring hard copy = \frac{HardCopy}{Total}\times 100

i.e. Percent of population preferring hard copy = \frac{21}{25}\times 100

i.e. Percent of population preferring hard copy = 0.84 × 100 = 84%

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