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.
To know more about degrees of freedom here.

Answer:
Step-by-step explanation:
x² + y² = 81
x + y = √81
x + y = 9
x ≥ 9
y ≤ 9
<h3><u>The value of y is equal to (-4 - 3x)/4.</u></h3>
Because there are two variables and only one equation, we cannot solve for the exact value of y.
However, we can still get a value of y.
y - 4 = 3x + 5y
Subtract y from both sides.
-4 = 3x + 4y
Subtract 3x from both sides.
-4 - 3x = 4y
Divide all terms by 4.
(-4 - 3x)/4 = y
Answer:
196 square meters
Step-by-step explanation:
If the floor mat is square and one side is 14m then all sides are 14m. Given this you would find area by multiplying length by width.
L=14 W=14
14x14=196
There are 196 square meters
