Step-by-step explanation:
The expected value is the sum of each outcome times its probability.
E = (0.70)(50000) + (0.05)(0) + (0.25)(-3500)
E = 34125
The store is expected to gain $34,125.
The answer to the question
Answer:
368 in^2
Step-by-step explanation:
To find the entire surface area, do the following:
Find the area of the base and then multiply it by 2:
(6 in)(5 in)(2) = 60 in^2
Find the area of one side and then mult. it by 2: then find the area of the other side and mult. that by 2 also. Add together these 3 results:
(6 in)(14 in)(2) + (5 in)(14 in)(2) + 60 in^2 = 368 in^2
Use the distributive property...
46 + 2a = 34
subtract 46 from each side
2a = -12
divide by 2
a = -6
