Answer:
<u>567</u> people were surveyed.
Step-by-step explanation:
Given:
A survey claims that the percent of an entire population that agrees with redeveloping the city park is likely between 49.1% and 57.5%.
Now, to find total people who were surveyed.
<em>According to survey percent of population agrees between = 49.1% to 57.5%.</em>
So, we need to find the error of margin:



Let the number of people surveyed be 
Now, to get the number of people surveyed:



<em>By cross multiplying we get:</em>
<em />
<em />
<em />
<em />
<em>Using square root on both sides we get:</em>

<u>Approximately:</u>
<u />
<u />
Therefore, 567 people were surveyed.
Answer:
32.
Step-by-step explanation:
Direct proportionality is the type of proportionality where an increase in one quantity or variable causes a corresponding increase in another quantity.
Therefore; y varies directly as x
Hence; y α x
y =k x where k is a constant
if y= 28 and x = 7 , then k = 28/4 =4
hence, y = 4 k
when x = 4, then y= 16
Answer:
4/5
Step-by-step explanation:
Rise = 4
Run = 5
