The measure of each interior angle in a regular hexagon can be calculated using the formula (n-2) * 180/n, where n is the number of sides. For a hexagon, n=6, so the measure is (6-2) * 180/6 = 120 degrees.

A regular quadrilateral is a square, and each angle in a square measures 90 degrees.

The exterior angle of a triangle is equal to the sum of the two opposite interior angles. Therefore, the exterior angle = 50 + 60 = 110 degrees.

The exterior angle of a triangle is equal to the sum of the two opposite interior angles. Therefore, the exterior angle = 50 + 60 = 110 degrees.

First, arrange the data: {1, 3, 5, 7, 9}. The median is the middle value, which is 5.

Median = 6 (middle value of the ordered set).

Sorted data: 1, 2, 3, 4, 5. Median = 3 (middle value).

Median = 9 (middle value).

Median = 6 (middle value of the ordered set).

Arranging the numbers: 10, 12, 14, 15, 18. Median = 14.

Arranging in order: 1, 2, 3, 4, 5. Median = 3.

Median = 8 (middle value in ordered list).

Median = (12 + 15) / 2 = 27 / 2 = 13.5.

The middle term is T(5) = C(8,4) * (2)^4 = 70 * 16 = 1120.

Midpoint = ((1+3)/2, (2+4)/2) = (2, 3).
