Hello there!
The median is the middle of the data set. Since we only have 7 numbers, we can arrange it from greatest to least, however the program has already done that. So, to find the median for this data set, all we have to do is simply find the middle number. The median would be 9 for this data set.
Damiel sold 12 more cds on the 7th day than the average over the first 6 days. to show work find the mean(average) of the 6 numbers. and subyract that from 25.
Answer:
Using the relation between angles and sides of any triangle the answer is:
Third option: WX, XY, YW
Step-by-step explanation:
<X=90° (right angle)
<W=51°
<Y=?
The sum of the interior angles of any triangle is 180°, then:
<W+<X+<Y=180°
Replacing the given values:
51°+90°+<Y=180°
141°+<Y=180°
Solving for <Y: Subtracting 141° both sides of the equation:
141°+<Y-141°=180°-141°
<Y=39°
The order of the angles from smallest to largest is:
<Y=39°, <W=51°, <X=90°
The opposite sides to these angles must be ordered in the same way:
Opposite side to <Y: WX
Opposite side to <W: XY
Opposite side to <X: YW
Then the order of the sides from smallest to largest is:
WX, XY, YW
<wxz + <zxy= <wxy
<wxy= 105
105/2= 52.5
52.5 + 52.5 = 105
105 = 105
m<wxz = 52.5
