Answer:
X as an angle will be equal to 140°
Step-by-step explanation:
As AO = BO, AOB is an Isosceles triangle which has 2 equal angles OAB=OBA=20°, therefore BOA is equal to 140°
x is the angle opposite to BOA which will have the same angle measure.
The Solution:
Given:
Required:
Find the standard deviation of the probability distribution.
Step 1:
Find the expected value of the probability distribution.


Step 2:
Find the standard deviation.




Thus, the standard deviation is 1.60
Answer:
1.60
An exterior angle equals the sum of the remote interior angles
.
So
x + 60 = 95
x = 95 - 60
x = 35
Answer
B. 35
