Answer:
x =22.5
Step-by-step explanation:
x+3x = 90
x and 3x are complementary so they add to 90 degrees
Combine like terms
4x =90
Divide each side by 4
4x/4 = 90/4
x =22.5
answer: x = 22.5
explanation:
as the 3x and x are on a straight line with the angle of 90° we know that
3x +x = 90
4x = 90
x = 22.5
Answer:
Step-by-step explanation:
What is the mean absolute deviation for these data?
2
2.4
6.5
7
Answer:
The mean absolute deviation of first data is
and for second data is
Step-by-step explanation:
Mean of data is calculated as:
and mean absolute deviation is calculated as
The given first data : 10 7 1 6 7 9 8 10 2 5
mean absolute deviation
The given first data : 2 2.4 6.5 7
mean absolute deviation
Therefore, the mean absolute deviation of first data is
and for second data is
