20. You work for a deck and patio contractor and have been contracted to build a 4-foot-wide stone walkway around a circular pool. See the diagram below.
Pool
30 ft.
* Walk
All estimates are made by rounding material dimensions up to the next full unit. The stone tiles for the walkway cost
$12.00 per square yard. What is the estimated total cost of the stone needed, rounded up to the nearest dollar? Use 3.14
for T.

step-by-step explanation:

my butt

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

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.
