The best batch size is 1053.
Since 5% have failed, this means 95% have passed the test.
95% = 95/100 = 0.95
We can set up an equation to answer this:
0.95x = 1000
Divide both sides by 0.95:
0.95x/0.95 = 1000/0.95
x = 1052.6 ≈ 1053
        
             
        
        
        
400=12.50x+50
400-50=12.50x
350=12.50x
350÷12.50=x
28=x

Answer:
The expected loss is $275 million.
Step-by-step explanation:
Expected loss can be determined as the sum of the product of each possible loss by the its probability of occurence. In this situation, there are only two possible losses listed since the probability of no loss doesn't add any value to the expected loss and should be disregarded.
Expected loss (in millions) = EL

The expected loss is $275 million.

Answer:
XY is 4 units.              
Step-by-step explanation:
We are given the following in the question:
Right triangle ABC is similar to triangle XYZ. 
AB = 20.8 units
BC = 36.4 units
YZ = 7 units
We have to find the length of side XY.
Since the given triangles are similar, they have the following property:
The ratio of corresponding sides of similar triangles are equal.
We can write,

Putting the given values, we have,

Thus, the length of XY is 4 units.
