To solve this question, first look and see what are the variables the question is asking for. In this case, the question is asking for how many students ONLY have Rabbits and also how many students ONLY have birds.
Since the question is how many more rabbits are there than birds, you would need to find the difference which is 3.
25 - 22 = 3. 3 additional students have rabbits only compared to birds only.
Answer:
The correct answer is
b. random sampling error
Step-by-step explanation:
Sampling is a statistical method of selecting a predefined number of observations from a larger population to determine the characteristics of and to represent the larger population.
A sampling error is a type of error in statistics that is as a result of a difference between the calculated statistical values of a selected sample and that of the entire population. A sample of a population with an error does not properly represent the statistics of the population.
By the definition of sampling in statistics, sampling error can be eliminated by Increasing the size of the sample taken from the larger population, analogous central limit theorem.
Answer:
The value of x = 20
Step-by-step explanation:
Given:
∠BOC = 3x - 15
∠COD = 2x + 5
Find:
The value of x
Computation:
⇔ ∠BOC + ∠COD = 90
⇔ 3x - 15 + 2x + 5 = 90
⇔ 5x - 10 = 900
⇔ 5x = 90 + 10
⇔ 5x = 100
⇔ x = 100 / 5
⇔ x = 20
The value of x = 20
