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)

Dawn comma Sergio comma Tyrone comma and Jim have all been invited to a dinner party. They arrive randomly and each person arriv
professor190 [17]

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%

Scientists tag and release a group of salmon after they hatch. Later, they catch a sample of salmon that return to the river and
Liula [17]

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.
