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
All you need to do is add up all the sides to find the perimeter.
300*2=600+450+650=1700m
Final answer: 1700m
Ps.- You should write in pencil incase you need to re-write answers
Answer:
There are 3 ways
Step-by-step explanation:
The formula for a sector's area is:
1. A = (sector angle / 360 ) * (pi *r2)
2. A = (sector angle / (2*pi)) * (pi * r2)
3. A = (fraction of the circle) * (pi * r2)
Answer:
Width = 4 m
Length = 7 m
Step-by-step explanation:
given:
perimeter of a rectangle = 22m
L = 3 + W
perimeter = 2L + 2W
perimeter = 2 (3 + W) + 2W
22 = 6 + 2W + 2W
22 - 6 = 4W
W = 16 / 4
W = 4 m
L = 3 + W
L = 3 + 4
L = 7 m
check:
perimeter = 2L + 2W
22 = 2(7) + 2(4)
22 = 14 + 8
22 = 22 ---- OK
