One environmental consequence of the large-scale cultivation of cotton in the South was —

A) widespread soil exhaustion caused by decades of farming

B) drought caused by overuse of river water to irrigate farmland

C) air pollution caused by the use of cotton gins

D) widespread water contamination caused by fertilizer runoff

Widespread water contamination caused by fertilizer runoff

Step-by-step explanation:

cotton is a profitable non-food crop in the world. about 25 million people make huge income from cotton production  and about 7% labor get employed in many developing countries.

the production of cotton posses s many threat on the environment from the use of agrochemicals. The production of cotton degrades the soil severely and exposes the soil to erosion. the pesticides , fertilizers from the cotton field when been eroded causes widespread water contamination caused by fertilizer runoff.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
