The x² term will be C(5,2)x²·2³ = 80x².
The coefficient is 80.
_____
C(n, k) = n!/(k!·(n-k)!)
C(5, 2) = 5·4/(2·1) = 10
Answer:
A. & B.
Step-by-step explanation:
General form is ax2 + bx + c = 0.
Must contain an x2 term
Must NOT contain terms with degrees higher than x2 eg. x3, x4 etc

Answer:
Assuming population data

Assuming sample data

Step-by-step explanation:
For this case we have the following data given:
736.352, 736.363, 736.375, 736.324, 736.358, and 736.383.
The first step in order to calculate the standard deviation is calculate the mean.
Assuming population data

The value for the mean would be:

And the population variance would be given by:

And we got 
And the deviation would be just the square root of the variance:

Assuming sample data

The value for the mean would be:

And the population variance would be given by:

And we got 
And the deviation would be just the square root of the variance:
