Answer:
x=2
Step-by-step explanation:
7(5+2x)+x=65
35+14x+x=65
35+15x=65
15x=65-35
15x=30/15
x=2
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:
A total of 15 cups of punch.
Step-by-step explanation:
20% ( or 0.20) of the punch is pineapple juice so if you have 3 cups of this juice, by proportion, you can make 3 / 0.20 = 15 cups
First find average
(5+5+5+5+7+9)/6=6
now see how much they each are differnt
5 to 6 is 1
5 to 6 is 1
5 to 6 is 1
5 to 6 is 1
7 to 6 is 1
9 to 6 is 3
average those
(1+1+1+1+1+3)/6=8/6=4/3=1.333
answer is 1.33
