Answer:
a. 3
Step-by-step explanation:
An independent variable is the variable that is changed in an experiment to test its effects on the dependent variable. i.e. inputs
A dependent variable is the variable being tested, measured or predicted in an experiment. I.e a outcome
In this case, the the effects of the amount tutors are paid a week before exam, the amount of sleep before exam and the number of study hours are input variables to determine or predict a students score in exam
The independent variables are;
x1 =represents the amount paid to a tutor (in dollars) in the week before the exam
x2 = represents the number of hours of sleep in the week before the exam
x3 = number of study hours in the week before the exam
The dependent variable is the exam score
B0, B1, B2,B3, B4 are coefficients
This is an odd problem. The length and width look like they should be interchanged. Anyway I'll solve it and we'll talk about the results.
(x +7) (x + 3) = 396
x^2 + 7x + 3x + 21 = 396
x^2 + 10x + 21 = 396 Subtract 21 from both sides.
x^2 + 10x = 396 - 21
x^2 + 10x = 375
x^2 + 10x - 375 = 0 This probably factors.
(x + 25)(x - 15)
x + 25 = 0
x = - 25 which makes no sense. Negatives do not describe room dimensions.
x - 15= 0
x = 15. this is fine.
x+3 = 15 + 3 = 18
x + 7 = 15 + 7= 22
Check
=====
Area = L * W = 18 * 22 = 496. It does check.
22 should be the length
18 should be the width.
Answer:
Evaluate.
Step-by-step explanation:
If you attempt to do the equation 
, you will get a very long and complicated answer (which is 2.2233078e+21), so I am assuming that is not the question.
If you were to do 
, you would get a more rational answer of 62.566.
If you would comment on this post or be more specific on what exactly the question aims to ask, that would be a huge help. :)
