Answer:
The mean of the samples is 21
Step-by-step explanation:
Mean is defined as the average sum of numbers i.e total sum of given numbers divided by the total number.
Given the randomly selected numbers as shown;
7, 100, 1, 3, 7, 10, 15, 12, 17, 38
Total sum of numbers = 7+ 100 + 1 + 3 + 7 + 10 + 15 + 12 + 17 + 38
= 210
Total numbers given = 10
Mean = 210/10
Mean = 21
135 degrees because 180-45=135 and due to the lines being parallel, the interior angles are equal.
Answer:
Number of fish in 2006 = 845 fishes (Approx.)
Step-by-step explanation:
Given;
Number of fish in 2000 = 1,150 fishes
Decreasing rate = 5% per year
Find:
Number of fish in 2006
Computation:
Exponential decay function:
F = P[1-r]ⁿ
Number of year = 2006 - 2000
Number of year = 6 year
Number of fish in 2006 = 1,150[1-5%]⁶
Number of fish in 2006 = 1,150[1-0.05]⁶
Number of fish in 2006 = 1,150[0.95]⁶
Number of fish in 2006 = 1,150[0.735]
Number of fish in 2006 = 845.25
Number of fish in 2006 = 845 fishes (Approx.)
