Answer:
1 9/40
Step-by-step explanation:
Any calculator can tell you the sum is ...
1 + 2/16 + 0.6 - 1/2 = 1.225
The decimal fraction can be reduced, if you like:
225/1000 = (25)(9)/(25(40)) = 9/40
As a mixed number, the sum is 1 9/40.

Alternate solution
1 2/16 + 0.6 -1/2 = 1 1/8 + (6/10 -5/10) = 1 1/8 + 1/10
= 1 + (1/8 +1/10) = 1 +(5/40 +4/40) = 1 9/40
Answer:
a^2+b^2=c^2
a^2=c^2-b^2
a^2=10^2-5^2
a^2=100-25
a^2=75
a=7.7cm
Step-by-step explanation:
The z-score corresponding to a cumulative area of 1 - 0.0122 = 0.9878 is 2.25.
Therefore the z-score corresponding to a cumulative area of 0.0122 is the negative of 2.25 = -2.25.
