Answer:
Step-by-step explanation:
Let X be the solvent present
Then given that the manufacturer of industrial solvent guarantees its customers that each drum of solvent they ship out contains at least 100 lbs of solvent.
X is N(101.3, 3.68)
a) 
Probability = 0.6368
b)
means Z score = 1.88
X=100+1.88(s) =101.3
s=1.3/1.88=0.6914
Answer:
-101,430
Step-by-step explanation:
23 x 98 x 45 x 1 equals 101,430, but the real trick of the question is whether it is positive or negative.
23(-98) forms a negative number (-2,254)
-2254(-45) forms a positive number (101,430)
101,430(-1) forms a negative number (-101,430)
Mentally, they are numbers in which you can do mental math with since they are whole numbers
36,00÷ 12= 3,000 so that would be the average monthly loss.
9 is in parentheses therefore it's elevated above 3 that means you have to do operations on it first.
3 + (-9) = -6
The sum is negative.
