Ranking in order from best to worst : Point, line, plane.

Step-by-step explanation:

12.A point in geometry is a location with no size and is shown by a dot. A point is the most fundamental object in geometry that represents a position.

A line can be defined as a connected set made up of  infinitely many points.A line has one dimension and extends in infinitely in different directions.It has zero width and zero height.

A plane is an infinite set of points forming a connected flat surface that extends infinitely far in all directions. In a plane, the width, length and height are infinite.

13.

Points S and V are collinear points.

Points R, and U are collinear points

Points  Q and T are collinear points

The figure has no plane indicated

What rule changes the input numbers to output numbers?
Ket [755]
Y - (-6) = (-4 - (-6))/(2 - 1) (x - 1)
y + 6 = (-4 + 6)(x - 1)
y + 6 = 2(x - 1) = 2x - 2
y = 2x - 2 - 6 = 2x - 8
y = 2x - 8.

option b is the correct answer.

A bag contains even and odd numbered balls in the ratio of 3:7, respectively. For each of the following, what is the probability
Gre4nikov [31]

Answer:

a) 0.425

b) 0.65

c) 0.575

Step-by-step explanation:

The ratio of even balls to odd balls is 3:7.  That means if there are 3 even balls, then there are 7 odd balls.  That makes a total of 10 balls, of which 30% are even and 70% are odd.

a) There are 240 balls, so originally, 72 are even and 168 are odd.  30 of the odd balls are renumbered by multiply by 4.  An odd number times an even number is an even number, so 30 of the odd balls become even balls.  So there are now 102 even balls and 138 odd balls.  Therefore:

P(even) = 102 / 240

P(even) = 0.425

b) Originally, 70% of the balls are odd.  Half of those are renumbered by multiplying by 6, so they become even numbers.

P(odd) = 0.5 (70%) = 35%

P(even) = 30% + 35% = 65%

A third of the even balls are renumbered by multiplying by 5, so they remain even numbers.

Therefore, P(even) = 0.65.

c) Originally, 30% of the balls are even.  Half of those are renumbered by adding 3.  An even number plus an odd number is an odd number, so:

P(even) = 0.5 (30%) = 15%

P(odd) = 70% + 15% = 85%

Next, half the odd balls are renumbered by adding 5.  An odd number plus an odd number is an even number, so:

P(odd) = 0.5 (85%) = 42.5%

P(even) = 15% + 42.5% = 57.5%

Therefore, P(even) = 0.575.

Svetradugi [14.3K]
You have to figure out the highest common factor of each set of values:
9a + 21 = 3(3a + 7)
21b - 49 = 7(3b - 7)
54 - 6c = 6(9 - c)
8a + 32b = 8(a + 4b)
4p + 28q + 8r = 4(p + 7q +2r)
84a - 36b -12c = 6(14a - 6b - 2c)
6p + 9q + 15r = 3(2p + 3q + 5r)
18s - 30t + 54u = 6(3s - 5t + 9u)
Hope this helps :)
