The answer is 1/10 or 10%.
The solution is as follows:
The probability of Neil's group winning is 100/2000 or 1/20
The probability o Neil winning is 10/2000 or 1/200
The probability that Neil is the winner inside his group after being announced his group won is 10/100 or 1/10.

Step 1: x²-15=2x
step 2: x²-2x-15=0
step 3: (x-5)(x+3)=0
step 4: x-5=0 or x+3=0
step 5: x=5 of x=-3

Hello!</h2>
The answer is:
The correct option is the option D

<h2>
Why?</h2>
To calculate the acceleration, we need to use the following formula that involves the given information (initial speed, final speed, and time).
We need to use the following free fall equation:

Where:
is the final speed.
is the initial speed.
g is the acceleration due to gravity.
t is the time.
We are given the following information:



Then, using the formula to isolate the acceleration, we have:


Now, substituting we have:


Therefore, since we are looking for a magnitude, we have that the obtained value will be positive, so:

Hence, the correct option is the option D

Have a nice day!
Answer: 0.8461
Step-by-step explanation:
Given : 
Let x be the random variable that represents the cost for the hospital emergency room visit.
We assume that cost for the hospital emergency room visit is normally distributed .
z-score for x=1000 ,
Using z-value table , we have
P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642
=0.8461358≈0.8461 [Rounded nearest 4 decimal places]
Hence, the probability that the cost will be more than $1000 = 0.8461
