The measure of a single angle of deviation on a regular octagon is 45 degrees.

<h3>Polygons</h3>

An octagon is a shape with 8 sides and 8 angles. The sum of an interior angle of an octagon is 1080 degrees.

<h3>Point of interseection</h3>

The point where the intersection of lines meets forms an angle of 45 degrees. Hence based on the given question, we can conclude that the measure of a single angle of deviation on a regular octagon is 45 degrees.

If $-2 &lt; x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.
kotegsom [21]

Answer: (-9, 16]

This is the interval from -9 to 16. Exclude -9 but include 16.

=====================================================

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

-2 < x \le 3

5(-2) < 5x \le 5(3)

-10 < 5x \le 15

-10+1 < 5x+1 \le 15+1

-9 < 5x+1 \le 16

This converts to the interval notation  (-9, 16]

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.

Dave has 10 poker chips, 5 of which are red and the other 5 of which are white. Dave likes to stack his chips and flip them over
sergey [27]

Answer:

\frac{10!}{5!*5!}  -  \frac{5!}{3!*2!}  

Step-by-step explanation:

Given:

10 poker chips:

  • 5 red
  • 5 white

Let the stack has positions (1,2,3,4,5,6,7,8,9,10)

So we can find all possible outcomes of the stack is: \frac{10!}{5!*5!} =

and the possibility of a stack to be identical while flipping is: \frac{5!}{3!*2!}

So the different 10-chip stacks can Dave make if two stacks are not considered distinct:

\frac{10!}{5!*5!}  - \frac{5!}{3!*2!}
