Question

The answers to the 3 questions

Answer 1

• It is linear as the equation performs ax+by +c
• y = 90.2x - 177670
• number of student to enroll 2011 is 3722

Step-by-step explanation:

• Linear is a straight line.
• Quadratic is a square which generates parabola.
• Quadratic formula is (ax)^2 + bx + c = 0.
• Linear formula is ax+bx + c = 0
• To  forecast time series data modelling can be used.
• To form a linear equation y = mx + c.
• After finding x is the required value , m is the intercept and C constant.
• X axis have years and Y axis has the value.
• to find number of students x is 90.2 * 2011 - 177670.
• The result comes to 3722.
• In Data analysis predictive modeling is the second phase.
• It is important because it helps in associating to variables.
