Answer:
2x^2 + 3x + 4
Step-by-step explanation:
generally, using long division,
(2x^3-3x^2-5x-12)/(x-3) = 2x^2 + 3x + 4
Answer:
Average of amount of time students spend trying to find an eatery spot on campus.
The sample would be a pool of 100 students to survey from.
Population would be all the students attending Harvard university.
Statistic would be the average amount of time spend looking for eatery spot in campus.
The parameter would be the mean used to find the average amount of time spent looking for eatery spot in campus.
It was a convenient sample.
Step-by-step explanation:
A population is the entire pool from which a statistical sample is drawn. In this case our population is the entire students that attend Harvard University.
A sample is usually drawn from a population. In this case, the 100 students that were drawn from the population is the sample.
The sample was a convenient sample as the sample can be easily drawn from the population population, it doesn't depend on any probability.
5 - 7 = - 2 ;
- 2 - 7 = - 9 ;
-9 - 7 = -16 ;
"common difference" d is - 7 ;
The n-th term of an arithmetic sequence is of the form <span>an = a1 + (n – 1)d ;
</span>a50 = 5 + 49 × ( - 7 ) = 5 - 343 = - 338;
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.
To find weight you use the equation w=m*a. W is weight, m is mass, a is acceleration due to gravity. Since acceleration due to gravity is different on the moon than it is on earth that is the dependant variable. Since the persons mass does not change that is the independent variable
