The <u>correct answer</u> is:
0.872.
Explanation:
The correlation coefficient of a regression line is a measure of how closely the line fits our data. Negative correlation coefficients represent decreasing lines; positive correlation coefficients represent increasing lines.
The closer a correlation coefficient is to +1 or -1, the better the fit; a perfect positive fit is r=1 and a perfect negative fit is r=-1.
We can see in the graph that the line is very close to our data, so it is a pretty good fit.
The line is increasing; this means we want a correlation coefficient that is close to 1.
The best choice is 0.872.

6 pairs of socks cost $6.90.
so every sock is at least one dollar. one dollar per sock, then you take the .90 and divided between the 6 socks and you get 15, so one dollar and 15 cents per sock.
Hope this helps, have a nice day!
Answer:
The answer to your question is: 29 tickets for children and 58 tickets for men.
Step-by-step explanation:
Child = c = $ 5.50
Adult = a = $8.80
Equation
a = 2c
5.5c + 8.8a = 669.9
5.5c + 8.8(2c) = 669.9
5.5c + 17.6c = 669.9
23.1c = 669.9
c = 669.9 / 23.1
c = 29
a = 2(29)
a = 58

Answer:
Joy is correct
Step-by-step explanation:
we know that
1 cup=1/2 pint
step 1
Convert pint to cups
Divide 4/5 pint by 1/2 to convert to cups
so

step 2
