Answer:

6+x=23

Step-by-step explanation:

So, the number you need to find is x, so x plus 6 equals 23 (the sum of the two numbers).

Hope this helped :)

Answer: 23 - 6 = x

x = 17

Step-by-step explanation:

6 + x = 23

x = 23 - 6

23 - 6 = 17

x = 17

6 + 17 = 23

Hope this helps!

Find the mean absolute deviation for the set {-32, 9, 11, 12}
Zolol [24]
<h3>Answer:</h3>

A

Step-by-step explanation:

{-32, 9, 11, 12}

first, find the mean (Find the sum of the data values, and divide the sum by the number of data values )

(-32) + 9 + 11 + 12 = 0

0/0 = 0

then, find the absolute value of the difference between each data value and the mean: |data value – mean|.

-32 - 0= -32

9 -0 = 9

11 -0 = 11

12 -0 = 0

finally, find the sum of the absolute values of the differences. Divide the sum of the absolute values of the differences by the number of data values.

0 - 0 / 4 = 0

answer is 0 (A)

The sum of the angle measures of a polygon with s sides is 2340. find s.
Leviafan [203]
S=15 

Whatever the number of sides of a polygon,

the sum of its exterior angles is always <span>360∘</span>

Further, each pair of exterior angle and interior angle adds up to <span>180∘</span>

Hence in a polygon with s sides (or angles),

the sum of all the interior and exterior angles would be <span><span>180∘</span>×s</span>

and sum of interior angles would be <span><span>180∘</span>×n−<span>360∘</span>=<span>180∘</span><span>(s−2)</span></span>

As sum of angles is <span>2340∘</span>

Hence, <span>180<span>(s−2)</span>=2340</span> or <span>s−2=<span>2340180</span>=13</span>

and <span>s=13+2=15</span> and polygon is a Pentadecagon.

i hope u understand :)
