Answer:
B) -0.98
Step-by-step explanation:
Correlation coefficient is usually denoted with numbers ranging from 1 to -1. Automatically, this eliminates option C) as our possible answer, since -1.43 is outside the range.
The trend shown in the scatter plot describes a negative relationship because, as the values in the Y-axis decreases, the values at the X-axis increases. The possible correlation coefficient we are likely to get is one that is negative. This eliminates option A and option and option D is our possible correlation coefficient for the scatter plot given since both values are positive.
Option B) -0.98, best represents the correlation coefficient of the given scatter plot. Since the points on the scatter plot seem closely aligned on a straight line, a negative value if -0.98 is mostly the possible one to get.
Aritmetic has a common difference
-27 to -12 is a difference of 15
-12 to 3 is a difference of 15
an=a1+d(n-1)
a1=first term
d=common difference
fist term is -27
common difference is 15
an=-27+15(n-1)
84th term is n=84
a84=-27+15(84-1)
a84=-27+15(83)
a84=-27+1245
a84=1218
the 84th term is 1218
Answer:
53028.064 I think
Step-by-step explanation:
Answer:
$297.50
Step-by-step explanation:
If she earns 105 for three hours, she would be earning $35 an hour.
105/3=35
If she works 8.5 hours, to find the amount you would multiply the hourly rate ($35) by 8.5. So, the answer is
8.5x35=$297.50
The answer to that is 9.91
