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.

Answer:
The slope of the line would be -2.
Step-by-step explanation:
Because the equation is a line, the slope is the same throughout the entire graph on the equation.
Lets let f(x)=y=-2x+4.
f(0) = -2(0) + 4 = 4
f(0)=4
f(1) = -2(1) + 4 = 2
f(1)=2
Use the equation to find slope.
m(slope) = 
= 
= -2
<em>The slope would be -2.</em>
<em />
Or:
Use the equation y = mx + b where m=slope.
In the equation y=-2x+4, m=-2.
<em>The slope is -2.</em>
Answer:
x = 15.65
y = 3.5
Step-by-step explanation:
Step 1
Find the equation for x and y
Equation for x is given as
x² = 7( 7+28) ..........Equation 1
14(14 + y) = x²........ Equation 2
Solving for Equation 1
x² = 7( 7+28)
x² = 7(35)
x² = 245
x = √245
x = 15.65
From Equation 1 , x² has been determined to be 245
Therefore we substitute 245 for y in Equation 2
14(14 + y) = x²........ Equation 2
14(14 + y) = 245
196 + 14y = 245
14y = 245 - 196
14y = 49
y = 49 ÷ 14
y = 3.5
