Answer and explanation:
Given : Strands Copper wire from a manufacturer are analyzed forstrenghth and conductivity. The Results from 100 strands are as follows :
Strength Strength
High Low
High conductivity 74 8
Low conductivity 15 3
To find :
a) If a stand is randomly selected, the probability that is conductivity is high and its strength is high
The favorable outcome is 74
The probability is given by,

b) If a stand is randomly selected, the probability that its conductivity is low or strength is low
Conductivity is low A= 15+3=18
Strength is low B= 8+3=11
Conductivity is low and strength is low 
Probability is given by,




c) Consider the event that a strand low conductivity and the event that the strand has a low strength. Are these tow events mutually exclusive?
Since the events the stand has low conductivity and the stand has low strength are not mutually exclusive, since there exists some cases in which both the events coincide. i.e. Intersection of both the events exists with probability 0.03.
Answer:
No, it cannot make a triangle
Answer:
8.40
Step-by-step explanation:
Add them all up, which equals to 41.98 you then divide by 5 since you want 20%. you would get 8.396 which rounded to the next penny is 8.40
Answer:
The answer for the missing side length is 16
Step-by-step explanation:
You have to use Pythagorean's Theorem 
is the hypotenuse, which is 20 in this case
is the bottom, which is 12
and you have to solve for 
So




This cancels out the exponent

That's the missing side length
