Respuesta:
Botella, B = 0.5
Jarra, C = 2,5
Explicación paso a paso:
Dejar :
Garrafa = C
Botella = B
C = 5B - - - - 1)
3 garrafas más 7 botellas = 11 litros
3C + 7B = 11
C = 5B
3 (5B) + 7B = 11
15B + 7B = 11
22B = 11
B = 11/22
B = 1/2 = 0,5
Sustituyendo B = 0.5 en 1)
C = 5B
C = 5 (0,5)
C = 2,5
The probabilities are as follows:-
- if none of the digits is repeated 0.504
- If any of the digits can be repeated 1
- If any of the digits can be repeated but the 3 and 8 are not in the combination 0.24.

What is probability?</h3>
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The probability will be calculated as follows:-
Total combinations are = 10⁴ = 10000
A) if none of the digits are repeated:-The combinations will be 10 x 9 x 8 x 7 = 5040
Probability = 5040 / 10000
Probaility = 0.504
B) If any of the digits can be repeated:- The combinations will be 10 x 10 x 10 x 10 = 10000
Probabilityy = 10000 / 10000 = 1
C )If any of the digits can be repeated but the 3 and 8 are not in the combination the combinations will be 7 x 7 x 7 x 7 = 2401
Probability = 2401 / 10000 = 0.24
Therefore if none of the digits is repeated 0.50.If any of the digits can be repeated 1.If any of the digits can be repeated but the 3 and 8 are not in the combination 0.24.

The best description for point F is: b. Circumcenter of triangle ABC.
<h3>What is the Circumcenter of a Triangle?</h3>
The perpendicular bisector is the line is drawn from the vertex of a triangle and bisects the opposite side at right angle. A triangle has three perpendicular bisectors.
The point where the three perpendicular bisectors of a triangle intersects is called the circumcenter of a triangle.
The triangle in the image above has three perpendicular bisector that meets at point F.
Therefore, the best description for point F is: b. Circumcenter of triangle ABC.

Combining the operations
The allowed operations are:
Add the same amount to both sides (either x's or ones)
Subtract the same amount from both sides (either x's or ones)
Multiply both sides by the same number (but not by zero)
Divide both sides by the same number (but not by zero)
(There are others, too, but they are not needed in simple equations.)
The goal is to FIRST add and subtract until we have ONLY x's (blocks) on one side and ONLY ones (circles) on the other. Then, if you have more than one block, you need to divide so as to arrive to the situation with only one block on the one side, which is the solved equation!
