Answer:
x = 5.5 (nearest tenth)
Step-by-step explanation:
let x be the length of 1 side
given area of square poster is 30 in²
and
Area = (length of 1 side )²
hence
30 = x²
x = √30
x = 5.4772
x = 5.5 (nearest tenth)

Step-by-step explanation:

Answer:
MAD = 2
Step-by-step explanation:
<u><em>First We'll find the mean of data</em></u>
Mean = 
Mean = 4
<u><em>Then, we'll find absolute deviation</em></u>
=> |4-3| = 1
=> |4-2| = 2
=> |4-1| = 3
=> |4-1| = 3
=> |4-3| = 1
<em><u>Now, taking the mean of these absolute deviations:</u></em>
MAD = 
MAD = 
MAD = 2
Answer:
(2,-2)
Step-by-step explanation:
(5+(-1))/2=4/2=2
(-5+1)/=-4/2=-2
Answer: 44 degrees=========================================================
Since the given angle -404 is not between 0 and 360, we add 360 to it to get:
-404 + 360 = -44
We add another 360 to that result
-44 + 360 = 316
now we have a value between 0 and 360
Rules:
* If the angle is between 0 and 90, we stop here and simply write down that value
* If the angle x is between 90 and 180, then we compute 180-x
* If the angle x is between 180 and 270, then we compute x-180
* If the angle x is between 270 and 360, then we compute 360-x
* Note in the three rules above, the order of subtraction is always (larger angle)-(smaller angle) = reference angle
* The reference angle has one segment on the x axis (aka the reference angle is adjacent to the x axis)
Based on that, we see that 316 is between 270 and 360, so we use the rule that
360-x
In this case, x = 316
So,
360-x = 360-316 =
44The reference angle is
44 degrees and looks like what you see in the attached image.
