Answer:
1. $30
2. $47.50
3. $7.20
Step-by-step explanation:
1. ( 30 + 45 + 15 ) / 3 = 30
2. ( 18 + 93 + 34 + 45 ) / 4 = 47.50
3. ( 9 + 4 + 5 + 8 + 10 ) = 7.20

Answer:
It's the first choice y = (-5/2)x - 1.
Step-by-step explanation:
First find the slope of the line 5x + 2y = 12 by converting to slope-intercept form.
5x + 2y = 12
2y = -5x + 12
y = (-5/2)x + 6 so the slope is (-5/2).
The line we require had also a slope of -5/2 because it is parallel to the first line and it also passes through the point (-2, 4). So:
y - 4 = (-5/2)(x - -2) (the point-slope form)
y - 4 = (-5/2)(x + 2)
y = (-5/2)x - 5 + 4
y = (-5/2)x - 1 (answer)
angle 5 and angle 4 are exterior angles
Answer:
The bias most likely to be present in the survey results is;
Option A; This is question wording bias because the survey question attempts to influence subjects’ responses.
Step-by-step explanation:
A bias occurs when a group or outcome is intentionally or unintentionally favored over another group or outcome in the a general population.
There are two main types which are;
- Selection bias which includes; Non - response bias, non representative sample and voluntary bias
- Response Bias which includes wording bias, extreme responses, neutral responses e.t.c
Let's look at each of the options;
Option A; This is correct because what occurred is that the concerned student by telling the adults adverse effect of plastics in our environment, he is indirectly influencing the adults to have a bad mindset about the plastics. He is leading them on by the way he phrased the word to ask the question.
Option B; This is not the reason why it is a response bias. The reason it is a response bias is because he led them on with his wording of the question.
Option C; Like said in Option A & B above, the scenario is that of a response bias since they are giving answers.
Option D; Voluntary response bias is a type of non-response bias and so it is not correct here
