It is false that the <span>total area of a prism can be found by multiplying the perimeter of the base times the height of the prism. If you did that, you'd get the lateral area of that prism, and not the total area. You'd need to add the area of both bases in order to calculate what the total area of a prism is. </span>
you need help
nice for you / fyi this is payback
Giving the table below which shows <span>the percent increase of donations made on behalf of a non-profit organization for the period of 1984 to 2003.

Year: 1984 1989 1993 1997 2001 2003
Percent: 7.8 16.3 26.2 38.9 49.2 62.1
The scatter plot of the data is attached with the x-axis representing the number of years after 1980 and the y-axis representing the percent increase <span>of donations made on behalf of a non-profit organization.
To find the equation for the line of regression where </span><span>the x-axis representing the number of years after 1980 and the y-axis representing the percent increase of donations made on behalf of a non-profit organization.

Recall that the equation of the regression line is given by

where

and

Thus, the equation of the regresson line is given by

The graph of the regression line is attached.
Using the equation, we can predict the percent donated in the year 2015. Recall that 2015 is 35 years after 1980. Thus x = 35.
The percent donated in the year 2015 is given by

Therefore, the percent donated in the year 2015 is predicted to be 90.5
The answer is .0045 because you move the decimal place 4 times to the left.
