The table gives the probability distribution of the annual rate of return on the stock of MNP Company, Inc.
The expected value of the rate of return is ______%.
Answers
Answer: The expected value of the rate of return is 23.5%.
Step-by-step explanation:
Since we have given that
Annual Return Probability
15% 0.2
20% 0.4
30% 0.3
35% 0.1
We need to find the expected value of the rate of return:
As we know the formula for "Expected value ":
So, it becomes,
Hence, the expected value of the rate of return is 23.5%.
15%*0.2 + 20%*0.4 + 30%*0.3 + 35%*0.1 = 23.5%
Answer:
The expected value of the rate of return is 23.5%

First of all, your second term is already wrong. When you divided 8x² by 4 ,
you should have written 2x² , not 4x² .
Make that correction, and then divide the whole thing by 'x'.
Then you'll have x² - 2x + 1 = 0 .
You should have no trouble solving that one,
(especially since it's a perfect square)
That gives you two (equal) solutions. But you should also ask yourself:
"Self ! Where is the third solution ? A cubic equation like the original
one needs three solutions."
I'll give you that one:
Look over the original equation, and look at what happens to it when x = 0 .
Then the left side becomes zero, and the equation is 0 = 0 . Since that's a
true statement, " x = 0 " is another solution of the cubic equation, and now
you have all three of them.
x^2-2x+1=0
You can either factor, complete the square, or use the quadratic formula.
I'll factor this into (x-1)(x-1)=0
x-1=0, so x=1

The required simplified solution of the given expression is -4.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
= -6 - |3 - 7| × 4 ÷ 8 - (-2)
Simplifying the above expression using the PEMDAS rule,
= -6 -|-4|×4÷8+ 4
= -6 - 16÷18 + 4 [∵ |-4| = 4]
= -6 - 2 + 4
= -4
Thus, the required simplified solution of the given expression is -4.

So, about 18 inches.
Or 17.93in with significant digits.
To break it down, you can set up your information as a fraction (which I did for the first fraction.) Then you want your units to cancel out, so I put the 7.489 minutes on the top of the next fraction and multiplied them. The min canceled out and left me with in, so I know I had the correct answer.
