Answer:
the standard form of the equation is: a. y=7x^2-42x+67
The score which is assigned from 1 to 4 by the teacher to each student for the project and is most likely to be is 3 with 0.48 probability.
<h3>
What is probability distribution?</h3>
Probability distribution is the statistical model which represent all the achievable and similar values of a random variable that it can possess in a specified range.
A teacher assigns a score from 1 to 4 to each student project. the table below shows the probability distribution of the scores for a randomly selected student.
- Probability distribution score: 1, 2, 3, 4,
- x probability: p(x) 0.06, 0.20, 0.48, 0.26
In the above data, the height probability of selection is 0.48. This probability belongs to the score 3.
Thus, the score which is assigned from 1 to 4 by the teacher to each student for the project and is most likely to be is 3 with 0.48 probability.

The -3 in f(-3) is the X coordinate, so you need to find where the line is on the Y coordinate at that point.
The line is at Y = -9
Answer: x + 30 + 90= 180(sum of angles on a straight line)
x= 180-120
x=60
