Cindy purchased 100 bricks. Each brick is within 1/8 inch of the advertised length of 8 inches. Cindy will line the bricks up en
AURORKA [14]
If each brick is within 1/8 inches of 8 inches, then that's an error of
 \frac{(\frac{1}{8})}{8} =\frac{1}{64}
If we then take the total length if each brick is 8 inches,
100*8=800
Then take 1/64 of this
800*\frac{1}{64}=12.5[tex] So the upper and lower bounds are 12.5 inches either side of 800 inches 787.5, and 812.5 So we can say that [tex]787.5 \leq x \leq 812.5
Which would be the answer to part a. parts b and c would be the lower and upper bounds, so 787.5 and 812.5 respectively
Hope this helps
