Answer:Solving the quadratic equation, the coordinates of the roots are: (-1,0) and (-3,0)
The quadratic equation given is:
Which has coefficients .
Now, we find the solutions:
The coordinates of the roots are and , as a root is a value of x when y = 0, thus, in the problem, (-1,0) and (-3,0).

Explanation:
Answer:
The percentage of scores higher than 72 is 99.85%
Explanation:
The empirical rule states that about 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)
We can use the relationship below
255-σ(61)=72
61σ=255-72
61σ=183
σ=3
The area is as shaded below
The percentage of scores higher than 72 is 99.7%+0.15%=99.85%
