Answer:
720 different ways.
Step-by-step explanation:
Permutation has to do with arrangement. For example, in order to arrange 'n' objects in any order, this can only be done in n! ways since there is no condition or restriction on how to arrange the objects.
n! = n(n-1)(n-2)... (n-r)!
If there are 3 statistics books, 2 math books, and 1 computer science book on your bookshelf, the total number of books altogether is 3 + 2 + 1 = 6 books.
The number of ways that 6 books can be arranged in any order is 6!.
6! = 6(6-1)(6-2)(6-3)(6-4)(6-5)
6! = 6*5*4*3*2*1
6! = 120*6
6!= 720 different ways.
<em>Hence, the books on your shelf can be arranged in 720 different ways</em>.
Answer:
A las 15:00 horas la temperatura será de -15ºC, habiendo subido 12ºC desde el corte de luz.
Step-by-step explanation:
Dado que en un frigorífico la temperatura es de -27 °C, y después de un corte de luz a las 12:00 horas, la temperatura empieza a subir 2 °C cada media hora, para determinar cuál es la temperatura a las 15:00 horas, y cuánto ha variado la temperatura desde el corte de luz, se deben realizar los siguientes cálculos:
((15 - 12) x 2) x 2) - 27 = X
(3 x 2 x 2) - 27 = X
(6 x 2) - 27 = X
12 - 27 = X
-15 = X
Por lo tanto, a las 15:00 horas la temperatura será de -15ºC, habiendo subido 12ºC desde el corte de luz.
1-5/8=3/8
If he had 5/8 leftover, then he used 3/8.
