It is 3/2 • 3/4 because you have to make the mixed number an improper fraction. Theb you would solve 3/2 • 3/4 and get 9/8 and that simplified is 1 1/8
Answer:
Step-by-step explanation:
Answer:
50-25 2/3 - 9 3/4 - 8 1/2 = 6 1/12
Step-by-step explanation:
To do this without a calculator you need to get common denominator
a good choice would be 12 for the common denominator
50 x 12 = 600
25 x 12 = 300
convert to 2/3 to x/12, multiply top and bottom by 4
2/3 x 4 = 8/12
add this to the 300 to get 308/12
same with the other terms
9 x 12 = 108
convert 3/4 to x/12, multiply top and bottom by 3
3/4 x 3 = 9/12
add this to the 108 to get 117/12
and do the same for the 8 1/2
8x 12 = 96
convert 1/2 to x/12, multiply top and bottom by 6
1/2 = 6/12, add this to the 96
do the subtraction and simplify
Step-by-step explanation:
-10 or -20 satisfies the equation.
But when you substitute 10 in:
30-40<-50+8
-10<-42(wrong)
it's wrong
Answer:
Systolic on right

Systolic on left

So for this case we have more variation for the data of systolic on left compared to the data systolic on right but the difference is not big since 0.170-0.147 = 0.023.
Step-by-step explanation:
Assuming the following data:
Systolic (#'s on right) Diastolic (#'s on left)
117; 80
126; 77
158; 76
96; 51
157; 90
122; 89
116; 60
134; 64
127; 72
122; 83
The coefficient of variation is defined as " a statistical measure of the dispersion of data points in a data series around the mean" and is defined as:

And the best estimator is 
Systolic on right
We can calculate the mean and deviation with the following formulas:
[te]\bar x = \frac{\sum_{i=1}^n X_i}{n}[/tex]

For this case we have the following values:

So then the coeffcient of variation is given by:

Systolic on left
For this case we have the following values:

So then the coeffcient of variation is given by:

So for this case we have more variation for the data of systolic on left compared to the data systolic on right but the difference is not big since 0.170-0.147 = 0.023.
