I think that would be 9 I am not sure.

i don't know
Step-by-step explanation:
Answer:
x = 40
Step-by-step explanation:
Since FG and HI are parallel and BC is a transversal, then
∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus
3x + 20 + x = 180, that is
4x + 20 = 180 ( subtract 20 from both sides )
4x = 160 ( divide both sides by 4 )
x = 40
Answer:
136
Step-by-step explanation:
The absolute value function always returns a positive value , that is
| - a | = | a | = a
Then
| - 136 | = | 136 | = 136
Answer:
The standard deviation = 1.9
Step-by-step explanation:
standard deviation, ρ = sqrt ( 
)
Where u is the mean of the data, 
each given value, and N is the number of data given.
Mean, u = 
= 5.2
So that;
= 
= 0.64
= 
= 0.04
= 
= 10.24
= = 0.04
= 
= 7.84
Sum = 18.8
So that;
= 
= 1.9391
= 1.9
The standard deviation of the given data is 1.9
