Answer:
78% probability it contains no defects
Step-by-step explanation:
We have that:
10% have defects in shafts only.
8% have defects in bushings only.
4% have the two types of defects.
An assembly is selected arandom, what is the probability it contains no defects
Either it has at least one defect, or it has no defects. The sum of these probabilities is 100%. So
D + ND = 100
Probability that it has a defect
D = 10 + 8 +4 = 22%
No defects:
22 + ND = 100
ND = 78
78% probability it contains no defects
Answer: The answer is 8 units
Step-by-step explanation:
Answer:
x = 24.48, y = -15.52, z = 3.95 to the nearest hundredth.
Step-by-step explanation:
x+y-z=5 (a)
-x-4y-8z=6 (b)
3x+5y-4z=-20 (c)
Adding equations a and b:
-3y - 9z = 11 (d)
Now multiply equation b by 3:
-3x - 12y - 24z = 18 (e)
Adding c and e:
-7y - 28z = -2 (f) Multiply by 3 to give (g)
-3y - 9z = 11 (b) Multiply by -7 to give (h)
-21y - 84z = -6 (g)
21y + 63z = -77 (h) Adding g and h:
-21z = - 83
z = 3.952
and y is found bt substituting in equation d:
-3y - 9(3.952) = 11
y = ( 11 + 9(3.952) / -3
= -15.52.
Now find x by substituting for y an z in equation a:
x - 15.52 - 3.952 = 5
x = 5 + 15.52 + 3.952
= 24.476.
Answer:
0.28
Step-by-step explanation:
