For quite some time now, calculators have had statistical functions built in. Here we need to use the stat. function normalcdf, which has only two inputs when we're working with z scores instead of raw scores.
Here,
normalcdf(-100,1.25) = 0.894
This same result could be obtained using a table of z-scores.
Answer:
x=2,-8
Step-by-step explanation:
Answer:
A = 4/5 ft
Step-by-step explanation:
Area = length x width
A = 2 2/5 x 1/3
Turn the mixed number into an improper fraction:
2 2/5 = 12/5
A = 12/5 x 1/3
A = 12/15
You can divide the top and bottom by 3:
A = 4/5
There is no answer beyond this. I tried a computer system and it said no solution.
