- 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.
3rd that is it :( (hope this helps)
Answer:
7 donkeys
Step-by-step explanation:
Given
A system consisting of donkeys and tourists
Heads = 50
Legs = 114
Required
Calculate number of donkeys.
Represent donkeys with D and tourists with T.
By means of identification; donkeys and tourists (human) both have 1 head.
This implies that
Number of Heads = D + T
50 = D + T ----- Equation 1
While each donkey have 4 legs, each tourists have 2 legs.
This implies that
Number of legs = 4D + 2T
114 = 4D + 2T ---- Multiply both sides by ½
114 * ½ = (4D + 2T) * ½
57 = 4D * ½ + 2T * ½
57 = 2D + T ----- Equation 2
Subtract equation 1 from 2
57 = 2D + T
- (50 = D + T)
---------------------
57 - 50 = 2D - D + T - T
7 = D
Recall that D represents the number of donkeys.
So, D = 7 implies that
The total number of donkeys are 7
Answer:
1. D. 
2. D. 45 units.
Step-by-step explanation:
We have been two graphs.
1. To find the area of our given triangle we will use distance formula.

Upon substituting coordinates of base line of our triangle we will get,
Now let us find the height of triangle similarly.
Therefore, area of our given triangle is 50 square units and option D is the correct choice.
2. Using distance formula we will find the length of large side of triangle as:















Therefore, the perimeter of our given rectangle is 45 units and option D is the correct choice.
