What is 1.8r+9=-5.7r-6
Answers
1 subtract 9 on both sides of the equation, 1.8r=-5.7r-15
2 then add 5.7r on both sides as well, 7.5r=15
3 divide 7.5 on each side, r=2.
1.8r+15=5.7r
Subtract 1.8 from both sides
15=3.9r
Divide 15 by 3.9
3.8=r

D. 7x + 2y < 2
Explanation:
The two general forma of the inequality are:
y < mx + c .........> In this case, shading is below the boundary line
y > mx + c .........> In this case, shading is above the boundary line
Since we are looking for the inequality with shading below the boundary line, therefore, we are looking for an y < mx + c format
Now, let's check the givens:
y - x > 5
Rearranging, we would get:
y > x + 5
The shading is above the boundary line. This option is incorrect
2x - 3y < 3
Rearranging, we would get:
2x - 3 < 3y
The shading is above the boundary line. This option is incorrect
2x - 3y < 7
Rearranging, we would get:
2x - 7 < 3y
The shading is above the boundary line. This option is incorrect
7x + 2y < 2
Rearranging, we would get:
2y < -7x + 2
The shading is below the boundary line. This option is correct
3x + 4y > 12
Rearranging, we would get:
4y > -3x + 12
The shading is above the boundary line. This option is incorrect

This should be the answer
Given ƒ(x) = 3x - 1 and g(x)= -x + 6, find ƒ(-2) + g(5).
f(-2) = 3(-2) =-6 -1 = -7
g(5) = -(5) = -5 +6= 1
-7+1= -6
Answer: -6
g(x) = -x + 6
f(2) + g(5) = (3(2) - 1) + (-(5) + 6)
f(2) + g(5) = (6 - 1) + (-5 + 6)
f(2) + g(5) = 5 + 1
f(2) + g(5) = 6

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 fail to respond during a survey. Hence, a likely scenario is ; surveys were mailed to 500 people, and 200 of the surveys were completed and returned.
- 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 60% of the sample are non-responsive.
Therefore, a scenario where surveys were mailed to 500 people, and 200 of the surveys were completed and returnedexemplifies a non - response bias.

Final answer:
Nonresponse bias may occur if a significant portion of the population doesn't respond to a survey due to reasons like absence during survey administration, inability to access needed technology, or indifference towards the subject. Bias may also occur if specific demographic groups, notably impacted by the surveyed services, cannot be adequately reached or represented.
Explanation:
Nonresponse bias can occur in a number of situations when collecting resident opinions about city services through a survey. For instance, nonresponse bias may be present if a significant segment of the city's population does not respond to the survey. There may be various reasons for this, such as individuals not being at home when the survey is administered, people not having access to the technology required to complete the survey (like internet or a phone), or simply choosing not to participate because they don't feel strongly about the city services.
Furthermore, another scenario that might introduce nonresponse bias is if city services affect different demographic groups in drastically different ways. For instance, younger populations who may benefit from certain city services may be harder to reach due to long-working hours, increased commute times, or general increased mobility compared to older residents. If these groups do not or cannot respond, it skews the sample and does not provide a true representation of the entire population's opinions on city services.
