Is a
For the last one I’m not so very sure, hope I helped a bit tho.
Step-by-step explanation:
Answer:
a = 31
Step-by-step explanation:
Answer:
Step-by-step explanation:
As perpendicular lines have negative reciprocal slopes, the options will have a slope of 6/3 = 2
The only option with a slope of 2 is B. y = 2x -12
A has slope of -2
C has slope of 4
D has slope of -2
only thing to do is to verify the point
-8 = 2(2) - 12
-8 = -8 check
Determine the mean ,median,modes ,IQR,and rage for the data 3,8,6,6,4,6,9,9,12
Verdich [7]
Mean:
Add all the numbers:
3 + 8 + 6 + 6 +4 + 6 + 9 + 9 + 12 = 63
There are 9 numbers.
63 / 9 = 7
Mean = 7
Median:
Order all the numbers:
3, 4, 6, 6, 6, 8, 9, 9, 12
The median is 6.
Mode:
The number that appears the most is 6.
The mode is 6.
Inter-Quartile Range :
Median of 2nd part = 9
Median of 1st part = 5
Subtract:
9 - 5 = 4
The IQR is 4.
Range:
The highest number is 12. The lowest is 3
Subtract:
12 - 3 = 9
The range is 9.
Hope this helped☺☺
