Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
Answer:
A) Status of Rate structure
B) Rate of usage of Electricity
C) Double blind
D) Neither
Step-by-step explanation:
A) The Explanatory variable is the Status of Rate structure during peak hours
B) The response Variable
The response variable in this experiment is the rate of usage of Electricity
( i.e. via meter readings )
C) The experiment can be considered a double -blind because the participants do not know the group they are assigned to ( either standard rate or time-of-day rate structure) but can only read their meters while the technician does not know what rate structure the participants where assigned to or what meter was assigned to each group
D) The experiment Did not use matched blocks or matched pairs
Answer: 
is a rational number.
Answer:
-25
Step-by-step explanation:
You can round -98.5 to 100
Then round 3.8 to 4
Negative divided by positive is negative.
-100 ÷ 4 = -25
Answer:
X° + 44° = 2x° + 11° [ Sum of two adjacent interior angles of a triangle = opposite exterior angle]
=> - x° = 11°-44°
=> -x° = -33°
=> x° = 33°
Therefore the value of x° = 33°
