Answer:
J) 110.88 mm^2
Step-by-step explanation:
height =6.93x2=13.86
Area=13.86x16x0.5=110.88
82/4+20-15
82:4=20.5
20.5+20=40.5
40.5-15=25.5
Answer:
Step-by-step explanation:
Use the normcdf( function on a basic calculator as follows:
normcdf(-1000, 9750, 12000, 4500). Result: 0.307. This is the area under the standard normal curve to the left of 9750.
But we want the area under the standard normal curve to the right of 9750, so we subtract this 0.307 from 1.000, obtaining the desired result: 0.693. This roughly corresponds with the last of the given possible answers, 69.15%.
