Answer:
400
Step-by-step explanation:
The probability of a negative result for a batch will be "0.3487".
Given values are:
Positivity rate,
Batch size,
Now,
The probability of negative result will be:
→ ![P (batch \ negative) = (1-p)^n](https://tex.z-dn.net/?f=P%20%28batch%20%5C%20negative%29%20%3D%20%281-p%29%5En)
By substituting the values, we get
→ ![=(1-0.1)^{10}](https://tex.z-dn.net/?f=%3D%281-0.1%29%5E%7B10%7D)
→ ![= (0.9)^{10}](https://tex.z-dn.net/?f=%3D%20%280.9%29%5E%7B10%7D)
→ ![= 0.3487](https://tex.z-dn.net/?f=%3D%200.3487)
Thus the answer above is right.

Answer:
Step-by-step explanation:
m∠AOB+m∠BOC=180°
m∠AOB=8x+51°
m∠BOC=6x-25°
~
![\tt 8x+51+6x-25=180](https://tex.z-dn.net/?f=%5Ctt%208x%2B51%2B6x-25%3D180)
![\tt 14x+26=180](https://tex.z-dn.net/?f=%5Ctt%2014x%2B26%3D180)
![\tt 14x=180-26](https://tex.z-dn.net/?f=%5Ctt%2014x%3D180-26)
![\tt \cfrac{14x}{14} =\cfrac{154}{14}](https://tex.z-dn.net/?f=%5Ctt%20%5Ccfrac%7B14x%7D%7B14%7D%20%3D%5Ccfrac%7B154%7D%7B14%7D)
![\tt x=11](https://tex.z-dn.net/?f=%5Ctt%20x%3D11)
m∠AOB:-
![\tt 8(11)+51](https://tex.z-dn.net/?f=%5Ctt%208%2811%29%2B51)
![\tt =88+51](https://tex.z-dn.net/?f=%5Ctt%20%3D88%2B51)
![\tt =139^{o}](https://tex.z-dn.net/?f=%5Ctt%20%3D139%5E%7Bo%7D)
Therefore, m∠AOB=139°
