The fraction is already in its simplest form, can not be further simplified
The constant term in the expression is 7
Answer:

And for the deviation we have:

And that value represent the best estimator for the population deviation since:
Step-by-step explanation:
For this case we have the following data:
1.48,1.45,1.54,1.52,1.52
The first step for this cae is find the sample mean with the following formula:

And replacing we got:

And now we can calculate the sample variance with the following formula:

And replacing we got:

And for the deviation we have:

And that value represent the best estimator for the population deviation since:
Answer:
Area of triangle: 1/2*base*height
Here height= 4
Base= 8
Thus area= 1/2*4*8
=4*4
=16
Answer:
1/3
Step-by-step explanation:
There are six triangles
2/6 of them are green
We can simplify this to 1/3
