The answer choices are

A. The median decreased, and the mean increased.

B. The mean decreased, and the median increased.

C. Both the median and mean decreased, but the mean decreased by more than the median.

D. Both the median and mean decreased, but the median decreased by more than the mean.

The answer is B

Step-by-step explanation:

The mean decreased, and the median increased.

As previously mentioned, this is one of the simplest definitions of the mean, and some others include the weighted arithmetic mean (which only differs in that certain values in the data set contribute more value than others), and geometric mean. Proper understanding of given situations and contexts can often provide a person with the tools necessary to determine what statistically relevant method to use. In general, mean, median, mode and range should ideally all be computed and analyzed for a given sample or data set since they elucidate different aspects of the given data, and if considered alone, can lead to misrepresentations of the data, as will be demonstrated in the following sections.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
