Considering the concepts of the mean and the median of a distribution, the distribution of dates would be skewed to the left because the <u>mean would be less than the median</u>.
<h3>What are the mean and the median of a distribution?</h3>
- The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
- The median of a data-set is the middle value of the data-set, the value which 50% of the measures are less and 50% are greater.
A distribution is classified as left skewed if the <u>mean is less than the median</u>.
In this problem, we have that most coins would be from the current year, hence the median should be the current year, while there are no coins from a year ahead of the current year and there should be a few coins of older years, hence the mean would assume a value less than the median and the distribution would be left skewed.

560 divided by two equals 280
Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
Answer:
60
Step-by-step explanation:
All the angles in that triangle are the same due to the type of triangle.
