Determine whether the study is an experiment or an observational​ study, and then identify a major problem with the study. In a​

survey, 1465 Internet users chose to respond to this question posted on a​ newspaper's electronic​ edition: "Is news online as satisfying as print and TV​ news?" 52% of the respondents said​ "yes." This is an observational study because the researchers do not attempt to modify the individuals. What is a major problem with the​ study? A. The results apply only to Internet users. B. This is a convenience sample with voluntary​ response, which has a high chance of leading to bias. C. There is no blinding or​ replication, which has a high chance of leading to bias. D. The sample is not very large.

Answer:

B. This is a convenience sample with voluntary​ response, which has a high chance of leading to bias.

Step-by-step explanation:

There is a great chance that the survey will have bias because, the opinion of those that are not on the internet will not be included.

Only those that have the time and willing responded to the survey.

Because the survey is online it will be bias as those responding will tend to vote for the online news outlet than the print media and television.

Elan Coil [88]

Answer:the function representing profit, P = 3n + 200

Step-by-step explanation:

The function C = 2n + 200 represents his costs, in dollars, for producing n jars of salsa.

The revenue, or the amount he receives for selling n jars, can be represented by the function R = 5n.

Profit = revenue - cost or expenses.

Therefore,

The function representing Dominic's profit, P, for selling n jars of salsa will be

P = 5n - 2n + 200 = 3n + 200

Answer:

∠C = 80 ° ; ∠ T = 40°.

Step-by-step explanation:

Triangle CRS is isosceles because it has two sides of equal length. (CR and CS are radii).

An isosceles triangle has also two equal angles, which means that ∠CRS= ∠CSR.

Therefore, ∠C = 80 ° (180° – 50° - 50°)  because the sum of angles in a triangle is 180 degrees.  

∠C is the central angle of the arc RS.

∠ T is the inscribed angle of the arc RS.

An inscribed angle is half of a central angle that subtends the same arc on the circle, so the inscribed angle ∠ T is half of the central angle ∠C. Since ∠C = 80 °, we can easily determine the measure of ∠ T:  

80° divided by 2 is 40°.
