9,460,528,400,000,000 can be rounded off to
9,000,000,000,000,000.
A trick you can use for these questions is count the number of zeroes at the end.
There are 15 zeroes, hence the answer is
Proof:
Hence, the number of zeroes is equal to the exponent.

Answer:
Step-by-step explanation:
Given
Three and one-half yards of fabric i.e. 
yards
and five and one-half yards of fabric is 
yards
Difference between five and one-half yards and Three and one-half yards is
=2 yards which is positive
Thus it clear that 
Answer:
Solution-
We know that,
Residual value = Given value - Predicted value
The table for residual values is shown below,
Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a random pattern is obtained where the points are evenly distributed about x-axis.
We know that,
If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.
As, in this case the points are distributed randomly around x-axis, so the residual plot show that the line of regression is best fit for the data set.
Hope this helps!
