Answer:
a) Permutaciones
b) combinaciones
Step-by-step explanation:
a)
Dado que el orden de las 15 obras de arte más importantes es relevante, comenzando por la más popular y luego las que ocupan los lugares 2, 3, 4, y así sucesivamente. Cuando nos ocupamos del "orden de colocación", el tema se refiere a permutaciones.
b)
De un total de 320 obras, se deben "seleccionar" 125 para ser exhibidas, el proceso de selección implica combinaciones en las que el orden de la selección no importa.
Detailed explanation:
Work completed by Gardner each hour = 1 / 5
Combined work done by Gardner and assistant each hour = 1 / 4
Work done by the helper per hour
= 1 / 4 - 1 / 5
= 1 / 20
Time required for helper to finish the job:
= 20 hours
Answer:
Step-by-step explanation:
For resolution, the Euclidean division is necessary:
- The polynomial is expressed as 16-2x³-6x²+x+9=-2x³-6x²+x+9
- We will divide this by: 4+3x-2=3x+2 and analyze the remainder
A visual representation of the process is provided
- The remainder is 47/9, hence the value to subtract is 47/9
The distance formula is
. In the ordered pairs (4, 6), the first number 4 represents the
x-coordinate while 6 is the
y-coordinate. In (7, -3), 7 is the
x-coordinate and -3 is the
y-coordinate. Substituting these coordinates results in
. Since subtracting a negative is equivalent to adding a positive, we now have
Answer:
(a) What will his age be after 5 years?
"5 + y" years old
(b) What was his age 6 years ago?
"y - 6" years old
(c) If his grandfather’s age is five times his, how old is his grandfather?
"5y" years old
(d) His father is 6 years older than three times his age. How old is his father?
"6 + 3y" years old
