Answer:
The value of the test statistic is
Step-by-step explanation:
The formula for the test statistic is:
In which X is the statistic, is the mean,
is the standard deviation and n is the number of observations.
In this problem, we have that:
So
The value of the test statistic is
Answer:
Step-by-step explanation:
we know that
In a parallelogram the diagonals bisect each other
The figure XYZW is a parallelogram
so
VW=VY
VX=VZ
<em>Find the value of b</em>
VW=VY
substitute the given values
solve for b
Find the length of YW
----> by addition segment postulate
substitute the value of b
Answer:
The answer is -1/2
Step-by-step explanation:
We first start by removing x in order isolate the y variable
2y = 6 - x
y =
Further, we simplify the equation in order to get the value of m (slope)
y = 3 +
Therefore, our slope is equivalent to -1/2
