Answer:
(B) Yes, there is reason. The TV audience might not be representative of the population.
(E) Yes, there is reason. Call-in polls tend to be biased.
Step-by-step explanation:
According to the information given we might consider two answers.
The first answer is:
<em>(B) Yes, there is reason. The TV audience might not be representative of the population.</em>
Let's remember that for a sample to be representative of a population must be random and every person must have the same probability of being selected. Here, the question is targeted only to the TV show's audience, so the results can only be interpreted for this segment of the population.
<em>(E) Yes, there is reason. Call-in polls tend to be biased.</em>
The risk is that the people who call might be influenced by the show itself and would not give an unbiased answer. This creates a bias on the sample. Besides, as stated before, not all the elements of the population can be part of the sample.
Answer:
a) 5
Step-by-step explanation:
f(5) = 3x – 5/ 2
f(5) = 3(5) – 5/ 2
f(5) = 15 – 5/ 2
f(5) = 10/ 2
f(5) = 5
The numbers from which we are to determine the smallest number that can be divided leaving a remainder of 5 are 44, 55, and 220. We have to do the prime factorization of all the numbers to determine their least common multiple (LCM).
Factorization of 44:
44 = 11 x 4 = 11 x 2 x 2
Factorization of 55:
55 = 11 x 5
Factorization of 220:
220 = 11 x 20 = 11 x 5 x 4
Since 220 has all the factors from 55 and 44 then, the least common multiple is 220. Add 5 to the LCM in order to determine the unknown.
<em>ANSWER: 225</em>
Answer:
Step-by-step explanation:
(3x-2)(22-2x+1)
simplify (22-2x+1)
(3x-2)(23-2x)
distribute
69x - 6x^2 - 46 + 4x
simplify
A union of two sets is defined as the set of numbers included in set a, set b, or both, so the answer to this would be B, as this embodies the definition.
Hope this helps, and have a nice day!
