Answer:
<h2>The answer is 8.9 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-3, 2) and (1, -6)
The distance between them is
We have the final answer as
8.9 units to the nearest tenth
Hope this helps you
Given:
The equation is:
To find:
The value of a.
Solution:
We have,
On simplification, we get
On comparing both sides, we get
And,
Therefore, the value of a is 2.
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>
Answer:
t=-105
Step-by-step explanation:
What we need to do here is to isolate t.
Let's multiply both sides by -15.
7*-15= -105
t=-105
