A researcher is investigating the number of hours a given individual spends online on a given day during the current 2020 pandemic in the United States. She randomly selects 30 individuals and collects the following responses: 15 12 6.2 7 5.5 2 4 5 10 11 7 6 4 7 0
1 5 3.2 4 10 6 2 10 1.5 5.1 6.4 8 14 3 2

Required:
What calculation is preferred for the central tendency and spread if the distribution of values is skewed?

Median

Step-by-step explanation:

Usually, in statistics when we have a skewed distribution, to calculate the central tendency and spread we usually calculate the median.

Thus, the calculations preferred in this case is median.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
