It is only one line because a<span> set of points is collinear if they lie on a single straight line. This is very common to be applied in mathematics</span>
First you do 3.5z-2.7z= .8z then you divide .8 with -6, which gives you -7.5 so z= -7.5
Answer:
A. 0.186524036
Step-by-step explanation:
Cosine 79° 15'
But, 1° = 60'
Thus; 15' = 15/60 = 0.25°
Therefore;
cos 79° 15' = cos 79.25°
Cos 79.25° = 0.186524036
= 0.186524036
In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.
The number of independent ways by which a dynamic system can move, without violating any constraint imposed on it, is called number of degrees of freedom.
In other words, the number of degrees of freedom can be defined as the
minimum number of independent coordinates that can specify the position
of the system completely.

The degree of freedom represents the number of ways in which the expected classes are free to vary in the chi-square goodness-of-fit test.</span>
