First you have to find the slope with the equation y2 - y1 / x2 - x1 , then once you have found the slope (slope = -2) you simply plug it into the point slope formula. y-0 = -2(x-5) solving it algebraically you should arrive at Y=-2x+10. (the 5 and 0 were plugged in are two of the X and Y points of the line which is why we plugged them into the X and Y values of the equation)
Answer:
a. 24
b. 2
c. 0.0833 = 8.33%
Step-by-step explanation:
a.
The first "slot" of person to arrive has 4 possibilities, then the second "slot" will have 3 possibilities, as one has already arrived, then the third "slot" has 2 possibilities, and the fourth "slot" has just 1 possibility.
So, multiplying all these combinations, we have 4*3*2*1 = 24 possible ways they can arrive
b.
If the first and the last person are already "locked", we just have possibilities for the second and third person. The second will have 2 possibilities (Sergio or Tyrone), and the third will have only 1 (the person that wasn't the second between Sergio and Tyrone). So, the number of possibilities is 2*1 = 2
c.
If we have 2 cases where Dawn is first and Jim is last, from a total of 24 possible cases, the probability is 2/24 = 1/12 = 0.0833 = 8.33%

The best prediction of the total number of tagged salmon in a sample of 2000 is 100.
<h3><u>Predictions</u></h3>
To determine what is the best prediction of the total number of tagged salmon in a sample of 2000, the following calculation must be performed:
- 800 = 40
- 2000 = X
- 2000 x 40 / 800 = X
- 80000 / 800 = X
- 100 = X
Therefore, the best prediction of the total number of tagged salmon in a sample of 2000 is 100.

Answer:
2.24 hours
Step-by-step explanation:
time = distance/rate
t = 26.2/11.7
t = 2.24 hours
