Hi Thaddeush13,
Biases - " lacking a neutral viewpoint, or not having an open mind".
The potential biases that could hapen in this experiment are different intakes or types of coffee. For Example, Cold, Hot, Caramel. And each as a different size. Sugar intake is also another problem here.
Race relations would be seperated between the white and black. Role of women would be to do housework. And i'm not sure for the Consumerism

Take the average of the vectors degrees. So 112.5 degrees is the direction of the resultant.
Answer:
Explanation:

So first, we have to plug in zero and see if we can evaluate this limit simply from that.
When we plug in zero we get: (2e^0-2)/0
e^0 is 1 so we have 2-2/0 or 0/0. So we have an indeterminate form type 0/0.
This means we have to apply L'Hospital's Rule.
As a reminder L'Hospitals Rule is 
Meaning that we take the derivative of the top and bottom function as the approach some value "c". We can do this with a 0/0 indeterminate form.
So:
The derivative of 2e^x - 2 is just 2e^x
and the derivative of x is 1
So we are left with 
Plugging in zero we see this gives us 2 as 2(e^0) = 2(1) = 2.
Hence,
= 2
