A histogram is said to be skewed left whenever the barstend to have the greatest length to the right of its graph.Additionally, the mean for the set of data is to the left of thebar with the greatest length in the histogram.
We also refer to the histogram as having a negative skew,since the bars in the histogram tend to increase as weight lost increases, moving from the left to the right of the graph.This means there is an increasing number of gym members in the weight loss program that lose an increasing amount of weight.

The perimeter of a parallelogram is the sum of its two bases and two sides. The length of the base at the bottom of the parallelogram is 6+14=20 units. Since opposite sides of a parallelogram are equal in length, the base at the top of the parallelogram is also 20 units.
The right side of the parallelogram has a length of 10 units.Again, since opposite sides of a parallelogram are equal in length, the left side is also 10 units.
So, the perimeter, P, of the parallelogram is:P=20+20+10+10=60 units

The median is the middle value for a set of data. lf there are an even number of values in the set of data, the median isthe mean (or average) of the two middle values after the data has been put in order. Ordering our data from least to greatest, we have:

$7.90 $8.25 $9.15 $9.20 $9.50 $10.75 $10.75 $12.50

Since there are an even number of values, we must take themean of the middle two. The middle two values in the dataset are $9.20 and $9.50. Their mean is:
Mean=​\( \frac{$9.20+$9.50}{2} \)​=​\( \frac{$18.70}{2} \)​=$9.35
The median price for the eight different brands of eye makeup the department store sells is $9.35.
