Answer:
The answer to your question is:
x = 10
∡BOC = 52°
Step-by-step explanation:
Data
∡AOB = ∡COD = 25°
∡BOC = (4x + 12)°
∡AOD = 102°
Process
∡AOD = ∡AOB + ∡BOC + ∡COD
102° = 25° + 4x + 12 + 25 Solve for x
102 - 25 - 12 - 25 = 4x
4x = 40
x = 40/4
x = 10
∡BOC = 4(10) + 12
= 40 + 12
= 52°
Answer:
For each part selected, the probability of a defective part being produced must be 0.04.
The parts must be selected independently.
Step-by-step explanation:
For each part, there are only two possible outcomes. Either they are defective, or they are not. Each part has a 4% probability of being defective, and the probability of a part being defective is independent of other parts, that is, they are selected independently. These are the conditions under which this situation would be a binomial experiment.
So the correct answers are:
For each part selected, the probability of a defective part being produced must be 0.04.
The parts must be selected independently.

Answer:
See below
Step-by-step explanation:
Lets do the long division:-
- x - 5
-------------------
x + 4 ( -x^2 - 9x - 20
-x^2 - 4x Subtract:-
------------
-5x - 20
-5x - 20
The quotent is -x - 5 with no remainder so the graph will be a straight line with negative slope of -1, and y-intercept at (0, -5).
