Answer: 4
The distance between two points is measured by distance formula of coordinate system.
Step-by-step explanation:
Distance formula :
If two points L and M are given having coordinates L(x1, y1) and M(x2, y2), then the distance between these two points is D= (x2-x1)² + (y2-y1)²
So the distance between the points (3, 3) and (7, 3) is
D= (7-3)² + (3-3)² =16 = 4
Distance between the two points is 4

Answer:
k = 77/10
Step-by-step explanation:
The jar consist of blue, red and green marbles . The probability of each of them can be described as follows.
probability of blue marbles = 2/7
probability of red marbles = 3/k
probability of green marbles = 5/2k
The sum of the individual probability is equals to 1. Therefore,
2/7 + 3/k + 5/2k = 1
collect like terms
(6 + 5)/2k = 1 - 2/7
11/2k =(7 - 2) /7
11/2k = 5/7
cross multiply
10k = 77
divide both sides by 10
k = 77/10
