Find the value of the arc x.

Mathematics
1 answer:
julsineya [31]3 years ago
7 0

Answer:

216°

Step-by-step explanation:

Both chords are the same length, so the left and right arcs are both 72°.  The whole circle is 360°, so:

72° + 72° + x = 360°

x = 216°

Is the range always the best way to measure the variability for a distribution of quantitative data? why or why not?
Rudik [331]

The strongest indicator of variability in data sets with outliers or skewed distributions is the interquartile range. It's unlikely to be impacted by outliers because it's based on numbers that come from the centre half of the distribution.

Your data's spread from the lowest to the greatest value in the distribution is indicated by the range. The calculation of this variability index is the simplest.

If your distribution doesn't contain any extreme values, the range is typically a decent indicator of variability. The range can provide information about the breadth of the distribution when combined with metrics of central tendency. But if your data collection contains outliers, the range may be deceptive.

How many angles are alternate interior angles with angle 9?
Svetradugi [14.3K]

Answer:

Angle 7 and angle 15

Step-by-step explanation:

  • <em>Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.</em>

Alternate interior angles with angle 9 are:

<u>Transversal s, parallel lines are t and u,</u>

  • Angle 9 is in pair with angle 7

<u>Transversal u, parallel lines are s and r,</u>

  • Angle 9 is in pair with angle 15

5x-2y=12<br><br>6x+2y=32<br><br>find the solution
diamong [38]

Answer:

(4,4)

Step-by-step explanation:

There are two ways that you can solve this. You can solve it with the help of technology or you can solve it traditionally. I will show how to do it in both ways so you can pick which way you want to solve it.

<em>Traditional Method:</em>

5x - 2y = 12

6x + 2y = 32

Look at the variables and numbers in both equations. One of them has to be the same value but have to have opposite signs. The 2y in both equations are the same value but have different signs. That's what we want. We can add everything in the equation now. (5x + 6x), (-2y + 2y), and (12 + 32).

11x = 44

To get x alone, Divide each side by 11. Then we will get the value of x.

11/11x = 44/11

x = 4

Horray! We got x, but what about y? Pick one of the equations. I will go with 5x - 2y = 12. Substitute the x value inside the equation.

5(4) - 2y = 12

20 - 2y = 12

-2y = -8

y = 4

Good! We figured out y. Now we know the solution! The solution is (4,4).

<em>Technology Method:</em>

Grab a graphing calculator. Enter the equations. You will see two lines. Look at where they intersect. The point where they intersect is the solution. That line is (4,4). You could also do this on a piece of paper by graphing the equations.

I hope this helps! Let me know if you need any more help or if I got anything wrong.
