The line BC in the figure above is the AXIS of the cylinder.
Axis of the cylinder is the line formed by the centers of the bases of a cylinder.
The median is 50, answer B. It is the middle number of the data set so it is the median. If there are an even set of numbers, so obviously there will be two numbers in the middle, then you simply need to add them and divide by two. Hope this helps! :)
Girl I struggle with this
Among all students, sports is, by far, the most popular activity and watching TV is the least popular.
Yesterday's price of notebook = $3.45
Today's price of notebook = $3.20
We have to determine the percentage decrease in the cost of notebook.
Percentage decrease = (Decrease
Old price) ![\times 100](https://tex.z-dn.net/?f=%5Ctimes%20100)
So, percentage decrease = ![\frac{3.45-3.20}{3.45} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B3.45-3.20%7D%7B3.45%7D%20%5Ctimes%20100)
=![\frac{0.25}{3.45} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B0.25%7D%7B3.45%7D%20%5Ctimes%20100)
= 7.246%
= 7.25%
Therefore, there is 7.25% of decrease in the cost of the notebook.
