Question

I tried everything from adding to dividing, subtracting, multiplying but still no correct answer. Can someone help me out here please? Thank you!

Answer 1

Answer:

See explanation. You didn't specify on whether the problem asks for a fraction or decimal, so I put both decimal and fraction.

Step-by-step explanation:

First we answer a:

Total amount of people polled is 291. Number of people who wear glasses is: $48 + 51 + 26 = 125$

Divide to get the proportion: $\frac{125}{291}$ which is also equal to: 0.4295532646

Then we answer b:

b asks for the proportion of all above average readers who wear glasses, so the total number would be: $48 + 25 = 73$. The number of above average readers who wear glasses is then 48.

We then get the proportion: $\frac{48}{73}$, which is also equal to 0.6575342466.

Answer 2

Answer:

a)125/291

b) 48/73

Step-by-step explanation:

a) total of yes/total asked
