<h3>Answer is -2</h3>
I hope it is helpful for you ....
42
because 27+6(2.5)= 27 +15 = 42
<em><u>"Correlation Coefficient" is the value from between -1 and 1 indicates the strength of the correlation between two variables.</u></em> Galton calculated the correlation coefficient for the line of best fit, to see how strong the relationship was. Hope this helps you! Thank you for posting your question at here on Brainly. Have a great day. -Charlie
A parallelogram should have 2 sets of parallel lines. Let's find the slope of line PQ and RS to test.
PQ:
(4-2)/(1-(-3))
2/4
1/2
RS:
(2-0)/(3-1)
2/2
1
Because 1 does not equal 1/2 (the slopes are different) the lines are not parallel. Thus, the figure is not a parallelogram.
(10(1-(1/2)^5)/1-(1/2) =
20(1-1/32)
=155/8
