Answer:
(Picture below)
Step-by-step explanation:
To solve this you will first need to make a coordinate plane that is 10 by 10.
After you have done that you will need to know what slope intercept form is. Slope intercept form is 
and the equation that was given was 
. In the formula , 
is the slope or rise over run and b is where the line crosses the y axis.
Now that you know the basics of slope intercept form we can start graphing. so b in this equation is -6, so we will put the first point on -6. after we have done that we can start putting the points of the line. So since the slope is just -1x we will have to go down one and go to the right one about 3 times and just to finish it up go up and left on 3 times to. And there you have it.
Answer:
a) The act of selecting a sample of students that are enrolled in statistics classes exclusively is a kind of non-random selection, and <u>may contribute for the selection bias to happen since this sample population isn't representative</u> when related to all the students enrolled in this large university.
b) The non-response bias could happen when, from the 500 students sample, some of them might not be able to answer to the survey sent on their email, or simply chose not to answer it, declining to participate. With <u>less answers, the survey becomes less representative</u>.
c) The response bias could happen if students answer to their surveys in an innacurate way, usually if they support their opinion on personal beliefs that aren't always shared by the rest of the sample population. Since <u>the aim of the survey is to know the students' opinion on the foreign language classes topic, it is expected that response bias happens</u>, having in mind that opinion is a particular thought of each individual.
d) The most serious bias is the selection bias, since the validity of the whole research would be compromised if the sample population isn't representative of the group you aim to study. Without the correct representation of the aim group, the results from the survey are meaningless.
Answer:#2
Step-by-step explanation:
X/6 - 3 ≥ 2
x/6 ≥ 3+2
x/6≥5
x≥30
3 numbers in solution set: 36, 42, 48
If he starts with one piece and ends up with 5 pieces, then he makes 4 cuts.
It takes him 8 minutes to do the actual cutting, although he may take breaks
between cuts.
