Part 1: The lower quartile of a data is the value which divides the lower half of a data into two equal parts.
Given the data set: <span>25,8,10,35,5,45,30,20 Arranging the data set, we have: 5, 8, 10, 20, 25, 30, 35, 45
The lower half of the data set is: 5, 8, 10, 20 and half of the lower half of the data is given by (8 + 10) / 2 = 18 / 2 = 9.
Therefore, the </span><span>lower quartile of the data set is 9. (option c)
Part 2: The </span>box -and-whisker plots <span>are divided into sections using quartiles and extremes. In a box and whisker, the end point of the left whisker represents the minimum value while the right whisker represents the maximum number. The left edge of the box represent the lower quartile while the right edge of the box represent the upper quartile.
A line inside the box represent the median of the data set.
Part 3: </span><span>In constructing a box-and-whisker plot for the data set below, the left and right sides of the box is drawn at the lower and the upper quartile of the data set.
Arranging the dat set, we have: 1, 2, 3, 3, 4, 5, 6, 7, 8, 8, 9 The lower quartile of the data set is 3 while the upper quartile of the data is 8.
Therefore, the left side of the box is at 3 while the right side of the box is at 8. </span>
The potato is a root vegetable native to the Americas, a starchy tuber of the plant Solanum tuberosum, and the plant itself, a perennial in the family Solanaceae. Wild potato species, originating in modern day Peru, can be found throughout the Americas, from the United States to southern Chile.
Andrea is making a sandbox.She has made a wooden frame in her backyard that is 6 feet long, 6 feet wide, and 2 feet deep. She can purchase sand for $30 per cubic meter. How much will it cost for her to purchase sand? Hint: 1 foot equals 0.3048 meters.
I believe it's increasing on all fronts, because if you start from the right, you see that the y values always increase, hence they are increasing. They do it for when x<0 and when x>0. So, it should be increasing on all real numbers
