Farmer dave harvested his corn. he stored 5/9 of his corn in one large silo and 3/4 of the remaining corn in a small silo. the rest was taken to market to be sold.
a. what fraction of the corn was stored in the small silo?
b. if he harvested 18 tons of corn, how many tons did he take to market?

a. 1/3

b. 2 tons

Step-by-step explanation:

let the total corn store be unity

now corn left after storing in large silo = 1-5/9= 4/9

now 3/4 of the remaining is stored in small silo = 3/4 of 4/9= 3/4×4/9= 1/3

therefore 1/3 of total corn was store in small silo

b. corn left for market = 4/9 -1/3 = = 1/9

so, the 18 tons its 1/9 was marketed which means = 18/9 = 2 tons

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.
