Answer: x=37.8, you can solve by writing a proportion
Ths system of equations is
<span>8x+6y=48 ..............>y = 48/6 -8x/6
2x−3y=−6 ..............>y = 6/3 + 2x/3
If we use a graphic tool, we can easily check the solution,
which is
(x,y) = (3,4)
The ordered pair lies in Quadrant I</span>
The median would be the middle data point. Let’s list the points
25, 26, 31, 39, 32, 57
Put them in order from least to greatest
25, 26, 31, 32, 39, 57
There is an even amount of data so take the two center points and divide by 2
31 + 32 = 63
Divide by 2
31.5
There would be an average of 31.5 strokes
The relative frequency of it landing on tails is 20/30 or 2/3 or 0.667
