The given diagram is a scatter plot in which temperature is plotted against number of visitors.
As the number of visitors is rising with the rise in temperature, its a positive correlation.
As joining the dots is going to give a web of line segments, it is not going to be helpful to understand the trends.
The best way to understand the trends is to make the line of best Fit in such a way that the number of dots on either side are approximately the same.
I have attached the figure for your reference of the line of best fit.

Answer:
sinH ≈ 0.47
Step-by-step explanation:
sinH = = = ≈ 0.47 ( to the nearest hundredth )
Lets use the formula to solve this, where,
- R is the rate
- W is the number of workers/things
- T is time
- J is number of jobs/things
<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -
W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:
<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use (previously found) to figure out T.</em>
<em></em>
So it will take 10 seconds for 50 printers to print 50 pages.
ANSWER: 10 seconds
