Answer:54.117
Step-by-step explanation:
Mean=45.4
Standard deviation=5.3
=5%. =0.05
1-0.05=0.95
Normal Dist(40,10)
InverseCdf(0.95,45.4,5.3)
1/8*2x=16*2x
devide 2x from both sides 1/8=16(x)
1/8=16x divide 16 from both sides
which is x=0.008
19.98 rounded to the nearest whole number is 20.
In the number 19, 9 round the 1 to a 2 and the 9 becomes a 0 because of the 9 behind the decimal.
OR
You could think of a percent being 100. 98 is only 2 numbers away from 100 and thus you can round 19 up to 20.
Hope this helps! (:
