Answer:
2
Step-by-step explanation:
<u>Since it is AP, the common difference is same for any term:</u>
- (4x - 2) - (x + 1) = (6x - 3) - (4x - 2)
- 3x - 3 = 2x -1
- 3x - 2x = 3 - 1
- x= 2
<u>The first 3 terms are:</u>
<u>Since the last term is 18, it means this AP has 6 terms:</u>
<u>Answer: </u>as we need to find the value of x only, it is = 2
Your two cards could be a negative six and a positive two.
Answer:
0.15
Step-by-step explanation:
Step 1: Make sure the bottom numbers (the denominators) are the same

Step 3: Simplify the fraction (if needed)
Answer:
p(win)=0.00094
Step-by-step explanation:
-This is a factorial/combination question.
-The probability is calculated using the formula:
Where:
is the number of successful picks
is the total number of picks
Therefore, we calculate the probability as follows;
Hence, the probability of winning is 0.00094
The number could be any multiple of nine that ends in 4 or 9, like 9, 54, 99, 144, etc.
