The number of degrees of freedom is large, then the student's T distribution is close to the normal distribution.
The degrees of freedom is the number of observation in a sample that are free to vary when we estimate the statistical data. Degree of freedom will also indicate the independent piece of information in the data.
Basically, the T distribution or student's distribution is a family's of distribution that look identical to the normal distribution.
So, the number of degrees of the freedom is large then it will closely related to normal distribution.

Its a guess ok, i have no idea.
Answer:
Using the quadratic formula:
x = [-4 +- sqr root (16 - 4 * 1 * -1)] / 2 *1
x = [-4 +- sqr root (20)] / 2
x1 = [-4 + sqr root (20)] / 2
x2 = [-4 - sqr root (20)] / 2
x1 = 0.23607
x2 = -4.2361
Step-by-step explanation:
