Answer: The mean for the probability distribution will be 69.25.
Explanation:
Since we given that
![At\ x_1= -500 ,P(x) = 0.076\\](https://tex.z-dn.net/?f=At%5C%20x_1%3D%20-500%20%2CP%28x%29%20%3D%200.076%5C%5C)
![At\ x_2= -250,P(x)= 0.191\\](https://tex.z-dn.net/?f=At%5C%20x_2%3D%20-250%2CP%28x%29%3D%200.191%5C%5C)
![At\ x_3=0, P(x)= 0.265\\](https://tex.z-dn.net/?f=At%5C%20x_3%3D0%2C%20P%28x%29%3D%200.265%5C%5C)
![At\ x_4=250 , P(x)= 0.316\\](https://tex.z-dn.net/?f=At%5C%20x_4%3D250%20%2C%20P%28x%29%3D%200.316%5C%5C)
![At\ x_5=500 , P(x)= 0.152\\](https://tex.z-dn.net/?f=At%5C%20x_5%3D500%20%2C%20P%28x%29%3D%200.152%5C%5C)
As we know the formula for expectation of x i.e. known as mean for the probability distribution,
![E(x)=x\sum_{1}^{5} P(x)](https://tex.z-dn.net/?f=E%28x%29%3Dx%5Csum_%7B1%7D%5E%7B5%7D%20P%28x%29)
So, we apply this formula in our case,
![-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25](https://tex.z-dn.net/?f=-500%5Ctimes%200.076%2B%28-250%29%5Ctimes%200.191%2B0%5Ctimes%200.265%2B250%5Ctimes%200.316%2B500%5Ctimes%200.512%3D69.25)
![\mu = 69.25](https://tex.z-dn.net/?f=%5Cmu%20%3D%2069.25)
Hence, the mean for the probability distribution will be 69.25.
The opposite of 17.2 from 0 on a number line would be -17.2.
Answer:
√2=1.414
then :√8 +2√32 +3√128+4√50
√8=√2³ =2√2
2√32=√2^5 = 4*2√2 = 8√2
3√128 = 3√2^6*2=8*3√2 =24√2
4√50 =4√5²*2= 20√2
add results : 2√2+8√2 +24√2+20√2=54√2
<h2>
54√2=54×1.414=76.356 ( it is not in the options)</h2>
x=7-4√3
√x+ 1/√x
√(7-4√3) +1/√(7-4√3) =
(8-4√3)/√(7-4√3)
(8-6.93)/√(7-6.93) = 4 ( after rounded to the nearest whole number)
4 is your answer
