Answer:
1) 
2) 
3) 
And the variance would be given by:
![Var (M)= E(M^2) -[E(M)]^2 = 207.1 -(13.9^2)= 13.89](https://tex.z-dn.net/?f=Var%20%28M%29%3D%20E%28M%5E2%29%20-%5BE%28M%29%5D%5E2%20%3D%20207.1%20-%2813.9%5E2%29%3D%2013.89)
And the deviation would be:
4) 
And the variance would be given by:
![Var (J)= E(J^2) -[E(J)]^2 = 194.8 -(11.8^2)= 55.56](https://tex.z-dn.net/?f=Var%20%28J%29%3D%20E%28J%5E2%29%20-%5BE%28J%29%5D%5E2%20%3D%20194.8%20-%2811.8%5E2%29%3D%2055.56)
And the deviation would be:
Step-by-step explanation:
For this case we have the following distributions given:
Probability M J
0.3 14% 22%
0.4 10% 4%
0.3 19% 12%
Part 1
The expected value is given by this formula:
And replacing we got:
Part 2
Part 3
We can calculate the second moment first with the following formula:
And the variance would be given by:
And the deviation would be:
Part 4
We can calculate the second moment first with the following formula:
And the variance would be given by:
And the deviation would be:
I don’t really understand the question at hand but let me try to help
X is equal to 4 we know this because because the sign in between the number means greater than or equal to so 3 x 4 equals 12 and that makes the equation on right true and on the left x is also equal to for which also makes the statement on the right true as well so I think X = 4
I hope I was able to help and If not I’m sorry
Answer:
x=84
Step-by-step explanation:
thi is the answer of the questions
At three weeks both will have 17 the equation for jessie is (8+3x) the equation for riley is (23-2x). x is the amount of weeks. to find the answer yourself, take both equations and make them equal. ex. 8+3x=23-2x.
Answer:
625
600+20+5
Step-by-step explanation:
<em>Parenthesis</em>
<em>Exponent</em>
<em>Multiply</em>
<em>Divide</em>
<em>Add</em>
<em>Subtract</em>
<em>From left to right.</em>
<em>Do exponent first.</em>
<em>
</em>
<em>Standard form of 5^4 is: ⇒ 600+200+5</em>
<em>625 is the correct answer.</em>
<em>600+200+5 is the correct answer.</em>
