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:
B: 192pi - 144
Step-by-step explanation:
Area of the sector = (120/360) * pi * r^2
Area of the sector = 1/3 * pi * 24 * 24
Area of the sector = 192 * pi
Now to find the area of the triangle.
The triangle is an isosceles triangle That means two of its sides are equal. They are equal to the radius of the circle, which is 24.
the small angles are equal to
2x + 120 = 180 Subtract 120 from both sides
2x = 60 Divide by 2
x = 60/2
x = 30
The height of the triangle is derived from sin(30) = opposite / hypotenuse
sin(30) = 1/2
hypotenuse = 24
1/2 = opposite / hypotenuse
1/2 = opposite / 24 Multiply both sides by 24
1/2 * 24 = opposite
opposite = 12
The height = 12
r = 24
Area of the triangle = 1/2 * 12 * 24
Area of the triangle = 144
So the area of the shaded area = 192*pi - 144 which looks like B

Answer:
(b) The distribution of the last digits of ID numbers in a sample of 100 college students
Step-by-step explanation:
<u>Uniform Distribution Explanation</u>
In statistics, uniform distribution refers to a type of probability distribution in which all outcomes are equally likely.
The only possibility here is the distribution of the last digits since the last digit can be 0 thru 9 and each is equally likely to appear in a random sample of 100 students
The others can be eliminated
Heights can vary depending on gender, ethnic background etc. In fact heights will follow a normal distribution
Scores can vary, most students will be scoring around the mean follows a normal distribution
GPAs like scores can vary, most students will have GPAs close to the mean GPA so follows a normal distribution
