Answer: 22
Step-by-step explanation:
From the question, we are given the information that of the balloons recently sold by party store, 4 were purple and 8 were other colors. This means that the fraction of those that was purple is:
= 4/(4+8)
= 4/12
= 1/3.
Therefore, if there are 66 balloons, the number expected to be purple will be:
= 1/3 × 66
= 22
There'll be 22 purple balloons

It has rotational symmetry of order 3 about the centroid of any triangle. Turning the pattern 120° gives you the same pattern.
Answer:
x intercept is (3.75, 0) and y intercept is (0, 2.5)
Step-by-step explanation:
4x + 6y - 15 = 0
x int = (3.75, 0)
0*6 = 0
4x - 15 = 0
0 + 15 = 4x = 15
15/4 = 4x
x = 3 3/4 or 3.75
y int = (0, 2.5)
0*4 = 0
6y - 15 = 0
15 = 6y
15/6 = y
y = 2.5
