It’ll be C or B with no soul took by finding the value.

systems have no solution if they have the same slope, but different y-intercepts.

3/4x - 1/2y = 12, y = 2(3/4x - 12) = 3/2x - 24

ax - by = 9, y = (ax-9)/b, = ax/b -9/b

for the slopes to be the same, following must be true:

ax/b = 3/2x

a/b = 3/2

Correct answer is C

A city has designed a survey to collect information about residents’ opinions about city services. Which of the following descri
Maslowich

Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects <em>fail to respond during a survey</em>. Hence, a likely scenario is ; <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em>.</em><em> </em>

  • Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.

  • If 200 surveys were returned, then 300 of the sample participants did not respond. Which means <em>60% of the sample are non-responsive</em>.

Therefore, a scenario where <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em> </em>exemplifies a non - response bias.
