The temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 975 and a standard deviation of 40 degrees.
If bricks are fired at a temperature above 1130, they will crack and must be disposed of. If the bricks are placed randomly throughout the kiln, the proportion of bricks that crack during the firing process is closest to
(Note: Please enter your answer in decimal form. For example, 5.02% should be entered as 0.0502.)
