The mean absolute deviation of the data set is 4
Answer:
65
All the other numbers if you add up their digits it is 8.
1 + 7 = 8
2 + 6 = 8
4 + 4 = 8
6 + 5 = 11
26
Is only number divisible by 13.
44 is only divisible by 11
Step-by-step explanation:
Answer:

Step-by-step explanation:
For many of these identities, it is helpful to convert everything to sine and cosine, see what cancels, and then work to build out to something. If you have options that you're building toward, aim toward one of them.
and 
Recall the following reciprocal identity:

So, the original expression can be written in terms of only sines and cosines:





Working toward one of the answers provided, this is the tangent function.
The one caveat is that the original expression also was undefined for values of beta that caused the sine function to be zero, whereas this simplified function is only undefined for values of beta where the cosine is equal to zero. However, the questions states that we are only considering values for which the original expression is defined, so, excluding those values of beta, the original expression is equivalent to
.
Answer:
A) A and B are supplementary
Step-by-step explanation:
we know that
For any inscribed quadrilateral in the circle , opposite angles will be supplementary
so
In this problem
Angle A and Angle B are supplementary angles

Angle B and Angle D are supplementary angles

therefore
<u><em>The sentences that are true </em></u>
A) A and B are supplementary
Y = -2 x - 9
3 x - 4(-2 x - 9 ) = -8
3 x + 8 x + 36 = - 8
11 x = - 44, x = - 4
y = 8 - 9 , y = -1
This is a unique solution, the system is independent.
