Answer: 
Step-by-step explanation:
If we draw RP and PS, then in the quadrilateral formed, we know that 
, and since angles in a quadrilateral add to 360 degrees, this means 
.
Thus, arc RS also measures 126 degrees
The correct answer for the question that is being presented above is this one: "A. (3/8)." According to the general equation for conditional probability if P(AupsidedownuB) = (3/10) and P(B)= (2/5), then P(A|B) is 3/8.Here are the following choices:A. (3/8)B. (1/2)C. (3/4)D. (1/16)
Answer:
(d + 3) would be 10
Step-by-step explanation:
<u>Step 1: Distribute</u>
<u>Step 2: Subtract 13.5 from both sides</u>
<u>Step 3: Divide both sides by 4.5</u>
<u>Step 4: Determine what (d+3) is</u>
Answer: (d + 3) would be 10
The answer is B since a negative number being subtracted cancels out and becomes a number, for example: since its -(-3) it becomes positive.
Answer:
See below ~
Step-by-step explanation:
<u>Question 1</u>
- (2 + 3i) + (3 - 4i)
- <u>5 - i</u>
<u>Question 2</u>
- (3 – 5i) – (–2 – i)
- 3 - 5i + 2 + i
- <u>5 - 4i</u>
<u>Question 3</u>
- (2 − 4i)(1+ 3i)
- 2 - 4i + 6i - 12i²
- <u>14 + 2i</u>
<u>Question 4</u>
- 2i(-1 + 3i)
- -2i + 6i²
- <u>-6 - 2i</u>
