Easy peasy
just subsitute I(x) for the x in the h(x) so
h(I(s))=-(2s+3)^2-4
distribute and simplify
h(I(s))=-(4s^2+12s+9)-4
h(I(s))=-4s^2-12s-9-4
h(I(s))=-4s^2-12s-13
Answer:
0.9905,0.9837,0.8066
Step-by-step explanation:
Given that 10% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).
Each shaft is independent of the other and probability for non conforming is the same for each trial.
Hence X the among these that are nonconforming and can be reworked. is Bin with n =200 and p = 0.10
a) 
b) 
c) 
P is less than 200
im pretty sure thats it
You want to multiply 40 hours by the regular hourly pay which would be $9.14,
9.14*40= 365.6
Overtime is generally 1.5 times regular pay so take 9.14*1.5= 13.71 and this would be your overtime hourly rate
Regular hourly rate (1x) : $9.14
Overtime hourly rate (1.5x): $13.71
Take your 8 hours of OT and multiply it by 13.71
13.71*8= 109.68
Add 365.6 and 109.68 to get a final answer of 475.28. The answer would've been C
