From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;
<u><em>- Yes, the sampling method is biased. </em></u>
<u><em>- The likely direction of the bias is because you only asked 5 people which </em></u>
<u><em>is not a significant percentage of those offering psychology majors and as </em></u>
<u><em>such the 4 out of 5 gotten is likely going to be an over estimation of those </em></u>
<u><em>who are willing to pay to join this club.</em></u>
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 <em>sampling bias</em> since the population is not adequately represented.
Therefore, this would lead to sampling bias and thus the sample is biased.

To multiply decimals: Set up and multiply the numbers as you do with whole numbers. Count the total number of decimal places in both of the factors. Place the decimal point in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
Answer:
2.
a)1
b)1
c)1
Step-by-step explanation:
There's some identity trigonometric equation, which are valid for all angles,and they doesn't depends on the measure of angle!
some of em are follows:. (x is the given angle)
- sin(x)^2+cos(x)^2=1
- cosec(x)^2=1+cot(x)^2
- sec(x)^2=1+tan(x)^2
You can remember these identity, its gonna help alot.
now back to question,. {x is representing angles)
for (a) sin(x)^2+cos(x)^2=1, this is true for all x, dat means that for all the angle given in question(for ,15°,30°,45°,60° and 120°),we will get 1
for(b) ,
cosec(x)^2=1+cot(x)^2
i.e, cosec(x)^2-cot(x)^2=1, again this is true for all x dat means that for all the angle given in question ,we will get 1
for (c),
sec(x)^2=1+tan(x)^2
i.e,sec(x)^2-tan(x)^2=1,again this is true for all x, dat means that for all the angle given in question ,we will get 1
