1) The area is 81 Units
2) the picture of the shaded region isn’t provided so I am unable to answer sorry
Answer:
a



b
Step-by-step explanation:
From the question we are told that
The probabilities are
Supplier chosen A B C
Probability P(a) = 0.20 P(b) = 0.25 P(c) = 0.15
D E
P(d) = 0.30 P(e) = 0.10
Generally the new probability of companies A being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem

=> 
Generally the new probability of companies B being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem


=> 
=> 
Generally the new probability of companies C being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem


=> 
=> 
Generally the new probability of companies D being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem


=> 
=> 
Generally the probability that B, D , E are not chosen this year is mathematically represented as
![P(N) = 1 - [P(e) +P(b) + P(d) ]](https://tex.z-dn.net/?f=P%28N%29%20%3D%20%201%20-%20%5BP%28e%29%20%2BP%28b%29%20%2B%20P%28d%29%20%5D)
=> ![P(N) = 1 - [0.10 +0.25 +0.30 ]](https://tex.z-dn.net/?f=P%28N%29%20%3D%20%201%20-%20%5B0.10%20%2B0.25%20%20%2B0.30%20%5D)
=> 
Generally the probability that A is chosen given that E , D , B are rejected this year is mathematically represented as

Answer: -3 2/5
Step-by-step explanation:
When both integers are negative, you can treat them the same as positive numbers and add a negative sign to your final sum.
1+2 2/5 (or 2 4/10 or 2.4) is equal to 3 2/5. So (-1)+ (-2 2/5) is equal to -3 2/5, or -3.4.
Answer:
D. $0, $20, $90
Step-by-step explanation:
