Step-by-step explanation:
all elements of the data set have the same value. therefore there is no difference of the individual values to the mean value.
and the sum of these differences is therefore also 0.
Answer:
NM = 15
Step-by-step explanation:
There is a property of secants and tangents to a circle where:
The square of the tangent length is equal the length of the external segment of the secant times the whole secant length.
Therefore, in our question, we have that:

The values of NM, ML and MK are:



So we have:





So the length of NM is:

Answer: 5
Step-by-step explanation:
- the formula of n-th term of an arithmetic sequence.
We have:



Answer: C. 77.4
Answer:
y = -3x -2
Step-by-step explanation:
Rise over run is
, which is -3. That is the slope (M value). y intercept is -2, so that is the B value. Let's put it all in the equation.
y = -3x -2
