Answer:
a) 0.5 = 50% of flanges exceed 1 millimeter.
b) A thickness of 0.96 millimeters is exceeded by 90% of the flanges
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.
This means that 
(a) Determine the proportion of flanges that exceeds 1.00 millimeters.
0.5 = 50% of flanges exceed 1 millimeter.
(b) What thickness is exceeded by 90% of the flanges?
This is x for which:
So
A thickness of 0.96 millimeters is exceeded by 90% of the flanges
We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us
. If we move the 7 over by subtraction and set it equal to 0, we have
. In order to avoid a negative leading coefficient, we can change all the signs to get
so A = 1, B = 0, C = -18, first choice above.
The answer is x=0
Step by step explanation:
X+5=5
X+5-5=5-5
X=0.
Answer:
11.62%
Step-by-step explanation:
Calculation for What must the expected return on this stock be
Using this formula
Expected return=Risk-free rate+(Expected market return -Risk-free rate)*Beta
Let plug in the formula
Expected return=4.6%+(10%-4.6%)*1.30
Expected return=4.6%+(5.4%*1.30)
Expected return=0.046+0.0702
Expected return=0.1162*100
Expected return=11.62%
Therefore What must the expected return on this stock is 11.62%
(3x2-9) + (2x+9) =X
This is how you put the equation together
