I believe the answer would be B. 11 because you can see a pattern. Its just skipping.
Answer:
I'm not quite sure what you are asking but I think the pattern would lead to -3 being your answer.
Answer:
Answer is X = 100
Step-by-step explanation:
X+80=180 (co interior angle)
x=180-80
x=100
Answer:
<u>The answer is 112º.</u>
Step-by-step explanation:
We can multiply 34 by 2, considering there's 2 angles that are 34 each. We'd get 68. Subtract 180 - 68, you'd get 112.
<u>Thus, 112º would be your final answer. </u>
Hope this helped!
Answer:
<h3>
a) Mean=1.2</h3><h3>b) The standard deviation is
![\sigma=3.1](https://tex.z-dn.net/?f=%5Csigma%3D3.1)
</h3>
Step-by-step explanation:
<h3>Given that the discrete probability distribution below :</h3><h3><u>Outcome Probability
</u></h3>
0 0.35
1 0.36
2 0.14
3 0.08
4 0.04
5 0.02
6 0.01
<h3>a) To find the mean of this distribution :</h3><h3>The formula is
![E(X)=\sum X.P(X)](https://tex.z-dn.net/?f=E%28X%29%3D%5Csum%20X.P%28X%29)
</h3><h3><u>X P(X) XP(X) </u>
![X^2P(X)](https://tex.z-dn.net/?f=X%5E2P%28X%29)
<u /></h3>
0 0.35 0 0
1 0.36 0.36 0.36
2 0.14 0.28 1.12
3 0.08 0.24 2.16
4 0.04 0.16 2.56
5 0.02 0.1 2.5
6 0.01 0.06 2.16
_________________________________________________
![\sum X^2P(X)=10.86](https://tex.z-dn.net/?f=%5Csum%20X%5E2P%28X%29%3D10.86)
_________________________________________________
- Now substitute the value in the formula we get
![E(X)=\sum X.P(X)](https://tex.z-dn.net/?f=E%28X%29%3D%5Csum%20X.P%28X%29)
![E(X)=1.2](https://tex.z-dn.net/?f=E%28X%29%3D1.2)
<h3>Therefore Mean=1.2</h3><h3>b) To find Standard Deviation :</h3><h3>The formula is
![\sigma=\sqrt{X^2P(X)-(XP(X))^2}](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7BX%5E2P%28X%29-%28XP%28X%29%29%5E2%7D)
</h3>
- Substitute the values i the formula we have
![\sigma=\sqrt{10.86-(1.2)^2}](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7B10.86-%281.2%29%5E2%7D)
![=\sqrt{10.86-1.44}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B10.86-1.44%7D)
![=\sqrt{9.42}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B9.42%7D)
![=3.0692](https://tex.z-dn.net/?f=%3D3.0692)
<h3>Therefore the standard deviation is
![\sigma=3.1](https://tex.z-dn.net/?f=%5Csigma%3D3.1)
</h3>
