Step-by-step explanation:
The median is the middle score of a distribution. To calculate the median
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
Consider this set of numbers: 1, 3, 3, 6, 7, 8, 9. Since you have an odd number of scores, the median (middle number) would be 6.
What happens when you have an even number of scores so there is no single middle score? Consider this set of numbers: 1, 2, 2, 4, 5, 7. Since there is an even number of scores, you need to take the average of the middle two scores, calculating their mean
in this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3. So, for this example, the median is 3.
To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.
and θ is given by the arctan of the ratio of y to x.
Example:
To convert rectangular coordinate (3, 4) to polar coordinate
Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
r is given by the square root of the sum of the squares of the rectangular coordinate.
and θ is given by the arctan of the ratio of y to x.
Example:
To convert rectangular coordinate (3, 4) to polar coordinate
Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
Opposite angles in a parallelogram have equal measure.
The measure of angle TUV is 78 degrees
The given parameters are:
Start by calculating angle RSV.
--- angles in a triangle
So, we have:
Subtract 102 from both sides
Angles RSV and TUV are corresponding angles.
So, we have:
Rewrite as:
Hence, the measure of angle TUV is 78 degrees
