Answer:

The answer is "0.9192".

Step-by-step explanation:  

\mu=109\\\\\sigma=10\\\\n=25\\\\\to P(\bar{x}< 111.8)=P(\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}} < \frac{111.8-109}{\frac{10}{\sqrt{25}}})\\\\

                          =P(2

I need help ASAP because I’m struggling with this thing
sesenic [268]

Answer:

66°

Step-by-step explanation:

There are so many ways to get this answer. Angle seven and 5 are vertically opposite so they're equal. Angles 4 and 5 are co-interior so they add up to 180°. If 180 is the total of 4+5, and 5 is 114 then 4 = 180-114 which is 66.

Angles 7 and 3 are corresponding and corresponding angles are the same. 3 and 4 are on a straight line so they add up to 180. 180-114= 66

You can also use angles 8,6 and 2 to get your answer
