Alumber company specializes in recovering, cutting, and selling wood from trees discarded long ago. the company uses side-scan penetrating radar to find large quantities of logs in and around a river. a recent site contained perfectly preserved 38,000-year-old cypress trees buried 30 feet in a sand pit. sclentists have identified these as trees that became extinct more than 20,000 years ago. complete parts 1.-4. below 1. the cypress trees are 30 to 50 feet long if there are 14,375 trees at an average length of 40 feet, how many feet of wood will the company have? 575000 2. if the cypress is worth $70 per foot, what are the 14,375 trees worth? $ 4025 3. if the cost to recover the 30-to 40-foot trees is $380 and the cost to harvest the larger trees is $500, how much would it cost to recove all of the trees iof the trees are more than 40 feet long?

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the results from a pre-test for students for the year 2000 and the year 2010 are illustrated in the box plot. what do these results tell us about how students performed on the 29 question pre-test for the two years?

if we compare only the lowest and highest scores between the two years, we might conclude that the students in 2010 did better than the students in 2010. this conclusion seems to follow since the lowest score of 8 in 2010 is greater in value than the lowest score of 6 in 2000. also, the highest score of 28 in 2010 is greater in value than the highest score of 27 in 2000.

but the box portion of the illustration gives us more detailed information. the middle bar in each box shows us that the median score of 20 in 2000 is greater in value than the median score of 17 in 2010. further, we note that the box and whiskers divide the illustration into four pieces. each of these four pieces represents the same portion of students. so, the upper half of the students in 2000 scored in the same score range as the upper one-fourth of the students in 2010, see the illustration at a score of 20.

by considering the upper one-fourth, upper half, and upper three-fourths instead of just the lowest and highest scores, we would conclude that the students as a whole did much better in 2000 than in 2010. we would conclude that as a whole the students in 2010 are less prepared than the students in 2000.

in this section, we discuss box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. the key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
