Francesca wants to start exercising to burn at least 1500 extra calories per? week, but she does not have much spare time for exercise. according to a? website, she can burn an average of 3.5 calories per minute? walking, 4 calories per minute? cycling, and 8 calories per minute swimming. she would like her total time walking and cycling to be at least 3 times as long as she spends swimming. she would also like to walk at least 20 minutes per week. how much time should she spend on each activity not only to meet her goals but also to minimize her total exercise time per? week? what is her minimum exercise time per? week?

96.25 calories every 20 minutes

Step-by-step explanation:

i am not 100 sure but it seems she spents 5 minutes swimming and 15 minutes walking and cycling 5*8=40     7.5*4= 30      7.5*3.5=26.25

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.
