Draining a half cylinder tank. a trough is shaped like a half cylinder with length 5 m and radius 1 m. the tank is full of water when a valve is opened and water flows out of the bottom of the tank at a rate of 1.5m^3/hr . hint: the area of a sector of a circle of radius r subtended by an angle theta is r^2/2 times theta.
a: how fast is the water level changing when the water level is 0.5 m from the bottom of the trough?

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.  

translate k to n and reflect across the line containing jk.
