Answer:
x = and y =
Step-by-step explanation:
Known that he sum of angles on a straight line is . From the diagram;
2y + x + y =
x + 3y = ................ 1
Also,
2x + x + 2y =
3x + 2y = .............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y = ............. 4
7y = 360
y =
y =
substitute the value of y in equation 1,
x + 3y =
x + 3(51.4) =
x + 154.2 =
x = - 154.2
x =
Thus, x = and y =
*see attachment for the diagram of the two box plots referred to here.
Answer:
2 inches
Step-by-step explanation:
The median of a box plot is the data value that lies exactly where the vertical line divides the box into two.
Therefore:
Median for Class 1 = 17 inches
Median for class 2 = 15 inches
The difference in the medians of both box plots = 17 - 15 = 2 inches
