Let A1 = The land has oil
A2 = Land has no oil
B1 = Test Predicted that land has oil
B2 =Test Predicted that land has no oil
Required probability = P(A1/B2)
A1 and A2 are mutually exclusive and exhaustive. Hence we can use Baye theorem
P(A1/B2) = P(A1B2)/P(B2) =

Answer:
Step-by-step explanation:
The sum of the interior angles of a polygon with 
sides is 
. Since the shape in the figure has 5 sides, the sum of its interior angles is 
.
Therefore, we can set up the following equation:
Since 
and 
make up one side of a line, they are supplementary, as each side of a line is 
.
Thus, we have:

Question #32:</h3>
Solve: 4/m - 8 = 8/2
Cross Multiply: 4 * 2 = 8 * (m - 8)
Simplify: 8 = 8m - 64
Flip the Equation: 8m - 64 = 8
Add 64 to both sides: 8m + (-64) + 64 = 8 + 64
Simplify: 8m = 72
Divide both sides by 8: 8m/8 = 72/8
Final Answer: m = 9

<h3>
Question #33:</h3>
Solve: 7/b + 5 = 10/5
Cross Multiply: 7 * 5 = 10 * (b + 5)
Simplify: 35 = 10b + 50
Flip the Equation: 10b + 50 = 35
Subtract 50 to both sides: 10b + 50 - 50 = 35 - 50
Simplify: 10b = -15
Divide both sides by 10: 10b/10 = -15/10
Final Answer: b = -3/2

Answer:
- 8
Step-by-step explanation:
substitute q = - 14 and r = - 6 into the expression
q - r
= - 14 - (- 6)
= - 14 + 6
= - 8
