You are looking at around 81.5% i assume by shifting the standard deviation by the same amount on both sides the % will not change
i split the normal distribution curve into 8 pieces
.15 +2.35+13.5+34+34+13.5+2.35+.15 34+34+13.5=81.5%
the ones bolded are the sections that u r dealing with
now the standard deviation is only 4400 so these numbers are going to be skewed off to the right a bit however bcus both sides are skewed evenly i believe they balance each other out
im not completely certain of this but still i hope i helped if so give me a brainliest answer i need a few more to move up a rank -J (:

How are adding and subtracting decimals different from multiplying decimals

In bmultiplying, you always have to move the decimal of the product the amount of place values the decimal has in each factor, for example, 1.50 times 1.50= 2.25, the factors together have 4 decimals, so you move the decimal 4 times to the right (try it, it gets rid of alot of zeros in the answer.)
