Answer:
For systolic pressure data:

For diastolic pressure data:

Systolic pressure is slightly less variable, among individuals in the sample, than diastolic pressure.
Step-by-step explanation:
The coefficient of variation is defined as the percentage relative variation of a set of data with respect to its average. And it is calculated like this:



For systolic pressure data:

For diastolic pressure data:

It is observed that the systolic pressure shows greater standard deviation but less coefficient of variation. This is due to the greater magnitude of its measurement scale.
Systolic pressure is slightly less variable, among individuals in the sample, than diastolic pressure.
Answer:
x = 50
Step-by-step explanation:
101 + (x + 29) = 180
130 + x = 180
x = 180 - 130
x = 50
Answer:
The last one
Step-by-step explanation:
The last table represents a linear function, y = -2x + 3
Answer:
Step-by-step explanation:
1¾ miles/(2⅓ minutes) = (7/4 miles)/(7/3 minutes) = ¾ mile/minute
21 minutes × ¾ mile/minute = 15.75 miles
60 minutes × ¾ mile/minute = 45 miles
