Answer:
Sample = 1046
Population = All adults. 
Step-by-step explanation:
In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.
On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.

Answer:
63
Step-by-step explanation:
It took 3 hours for her to deliver 189 total.
We need delivery per hour for our answer.
189 / 3 = 63
63 new papers are delivered per hour.
 
        
                    
             
        
        
        

so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on
so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)
thus  (0.30x) + (175)(0.65) = (x+175)(0.50)
solve for "x"
 
        
             
        
        
        
Set up the equation. On a piece of paper, write the dividend (number being divided) on the right, under the division symbol, and the divisor (number doing the division) to the left on the outside. ...
Divide the first digit. 
Divide the first two digits.
Enter the first digit of the quotient.
