Answer:
22.5° and 67.5°
Step-by-step explanation:
The sum of complementary angles equal 90°.
Given that one of the complementary angles is 3 times larger than the other, let "x" represent the other angle.
Thus, the following expression can be written to represent this case:
Solve for x
Divide both sides by 4
The measure of the complementary angles are:
x = 22.5°
3x = 3(22.5) = 67.5°
The student's friend watch 1.5 movies every week.
Data provided to us {2, 14, 1, 2, 0, 1, 0, 2}.
Number of data values = 8
Sorted or rearranged data {0, 0, 1, 1, 2, 2, 2, 14}
Median of the data provided;
Median is the mid point value of the data provided to us, but as in this case there are 8 data provided (even number of data), we will take the average of the 2 mid values of the data.
Mid Values = 1 and 2
Mean of the data provided;
As we know, The data values provided are 0, 1 and 2, and there is 14 as well in the data which is the maximum value in the data provided to us but the value is far from the other data values provided to us. Therefore, the data value 14 is considered to be an outlier.
An outlier is the maximum value that increases the mean, which makes it larger than it should be.
If we were to compute the mean without the outlier,
Now, we have understood that the mean is sensitive to outlier can be easily manipulated. thus, mean is not the right option to go for in this case.
Therefore, the median value of 1.5 is the right option.
Hence, the student's friend watch 1.5 movies every week.
