You would like to start a club for psychology majors on campus, and you are interested to find out what proportion of psychology majors would join. The dues would be $35 and used to pay for speakers to come to campus. You ask five psychology majors from your senior psychology honors seminar whether they would be interested in joining this club and find that four of the five students questioned are interested. Is this sampling method biased, and if so, what is the likely direction of bias
Answers
From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;
- Yes, the sampling method is biased.
- The likely direction of the bias is because you only asked 5 people which
is not a significant percentage of those offering psychology majors and as
such the 4 out of 5 gotten is likely going to be an over estimation of those
who are willing to pay to join this club.
We are told that;
You want to start a club.This club is for psychology majors.You want to find the proportion of those in the psychology majors that will join this club you want to organize.Now, out of all the students offering psychology majors, you only asked 5 of them if they will be interested. Since 4 out of the 5 are interested and you want to use that to form a basis of the proportion of those interested , it would lead to sampling bias since the population is not adequately represented.Therefore, this would lead to sampling bias and thus the sample is biased.

Step-by-step explanation:
100% - 30% = 70%
I'm guessing you meant 1,200 not 1.20 (lol) so I'm just going to go with that.
1,200 * 0.70 = 840

Need to solve by steps
Answers
Answer: -14.5
What I did was Subtract 3.5 from -11.
When you add them together, you get 14.5, but 14.5 isn't correct, as that's a very large number compared to -11.
Answer:
-14.5
Step-by-step explanation:
-11 - 3.5
Because 11 is already negative, when you subtract a number from a negative, think of -11 becoming "smaller" (smaller being -14, or -25).
When doing -11 - 3.5, think if it as adding 11 and 3.5 together !
When you add them together, you get 14.5, but 14.5 isn't correct, as that's a very large number compared to -11.
You add a negative sign to said -14.5, and that's your answer !
Subtracting from a negative is confusing, so I taught myself to think of it as adding the numbers as if they were positive and adding a negative sign !

Point upper D left parenthesis negative 3 comma 5 right parenthesis. is a vertex of triangle DEF. After a rotation of the triangle about the origin, upper D prime is located at left parenthesis 3 comma negative 5 right parenthesis. Which of the following was the rotation of the triangle?
Answers
The rotation that the triangle DEF underwent is defined as follows:
180º around the origin.
RotationA rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.
A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:
90° clockwise rotation: (x,y) -> (y,-x)90° counterclockwise rotation: (x,y) -> (-y,x)180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y)270° clockwise rotation: (x,y) -> (-y,x)270° counterclockwise rotation: (x,y) -> (y,-x)In this problem, the coordinates are given as follows:
Original: (-3,5).Image: (3,-5).Hence the rule is:
(x,y) -> (-x, -y).
Meaning that a rotation of 180º around the origin was done.

After doing this, you will be left with the equation 160+3*7=195-2*7. We will look at the first part of the equation first. Using the rules of BIDMAS, you can calculate 3*7=21 and then 160+21=181. 181 is your final answer.
You can check that this is right by calculating the second part of the equation, and once done you should be left with 181. Again, using BIDMAS, you need to do 2*7=14 then 195-14=181. Now we know that everything is correct.
