Alex wrote this equation to represent the total distance she ran in two weeks.

16 = d + 9

which situation could be described by this equation?

a.
alex knows she ran a total of 16 miles. she does not know how many miles she ran the first week. she knows she ran 9 miles the second week.

b.
alex knows she ran 16 miles the first week. she knows she ran 9 miles the second week. she does not know how many miles she ran altogether.

c.
alex knows she ran 16 miles the first week. she knows she ran 9 more miles the second week than the first week. she does not know the total number of miles she ran.

d.
alex knows she ran 16 miles the first week. she knows she ran 9 fewer miles the second week than the first week. she does not know the total number of miles she ran.

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.  

no he doesnt because "-16' is negatiive
