The constant of proportionality is for every 1 x, there is 0.25 y. y = 0.25, and on a graph, x is always the "1." Since x is worth 1, y must be worth 0.25.
Answer: 12 red balls must be added
Step-by-step explanation:
Starting out with 15 balls, 6 red implies 9 blue. If blue remains 9, then we expect red to be 18 for a probability at 2/3. 18-6 = 12
Answer:
QV = 36 UNITS
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1.
QU is the median and V is Centroid. Therefore,
QV : VU = 2 : 1
Let QV = 2x & VU = x
QV + VU = QU
2x + x = 54
3x = 54
x = 54/3
x = 18
QV = 2x = 2*18 = 36
