The perimeter of the figure is 20.73 cm.
<h3>What is perimeter:</h3>
Perimeter is a closed part that surrounds a two dimensional or one length figure.
The perimeter of the figure above is the sum of the wholes sides. In other word the sum that surrounds the whole sides.
Therefore, the perimeter of the figure is as follows:
perimeter = 3.1 + 5.2 + 4.24 + 2.19 + 6
perimeter = 8.3 + 4.24 + 2.19 + 6
perimeter = 12.54 + 2.19 + 6
perimeter = 14.73 + 6
perimeter = 20.73 cm
Therefore, the perimeter of the figure is 20.73 cm.

Answer:
commutative property
Step-by-step explanation:
The <em>commutative property of multiplication</em> lets you swap the order of the operands (7*3) and 8 to make them have the order 8 and (7*3).
Given: all selections are without replacement
Let D=event that chip is defective
N=event that chip is normal
note that D and N are complementary.
x=undefined event
(a) Second is defective
Probability for second chip to be defective
P(xD)=P(ND)+P(DD)
P(ND)=(80/100)*(20/99)=1600/9900
P(DD)=(20/100)*(19/99)=380/9900
=>
P(xD)=(1600+380)/9900=1980/9900=1/5
(b) All three are defective
P(DDD)=(20/100)*(19/99)*(18/98)=19/2695
Note: in probabilities, it is preferable to use the exact values (i.e. fractions).
