Answer:
in a region with a letter
Step-by-step explanation:
For a certainty, then probability is 1.
That means sum of probability of all events in the sample space.
This means P(A)+P(B)+P(C)+P(D)=1
This is equivalent to:
P(A or B or C or D)=1
Hence for certainty, the region must be:
A or B or C or D
So the correct answer is in a region with a letter.
May makes $23.25, Inez makes $2325, and Carolyn makes $232.50
Based on the information given the gain or loss percent on the whole transaction is 1%.
<h3>Gain or loss percent:
</h3>
First step is to calculate the profit on the whole transaction
Profit=(8%×8,000)-(6%×8,000)
Profit=$640-$480
Profit=$160
Now let calculate the gain or loss percentage on the whole transaction
Gain or loss percentage=160/(8000+8000)×100
Gain or loss percentage=160/16000×100
Gain or loss percentage=1%
Inconclusion the gain or loss percent on the whole transaction is 1%.

Answer:
100
Step-by-step explanation:
Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.
Since the sum of angles in a triangle is 180.
180-(25x2) will give you the last angle in one of the triangles.
The other angle is identical so the angle at the top of the other triangle will also be 130.
The sum of angles in a circle is 360.
Therefore, angle x = 360-(130x2)
X= 100
