Answer:
85 m
Step-by-step explanation:
5696/67=85
Let
In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:
So, the base case is ok. Now, we need to assume 
and prove 
.
states that
Since we're assuming , we can substitute the sum of the first n terms with their expression:
Which terminates the proof, since we showed that
as required
Answer:
A subway train arrives every 10 minutes during rush hour. We are interested in the length of time a commuter must wait for a train to arrive. The time follows a uniform distribution. Find u, which is the average length of time a commuter must wait for a train to arrive. Round to one decimal place. = 3
5x(4x^3 + 3x - 2)
There’s a 5 and a x common.
Answer:
28BS
Step-by-step explanation:
Compré 30 libros a 40 bs cada uno;
Precio de costo = 30 × 40BS
= 1200 BS
Vendí unos pocos a 360 Bs, a 36 Bs cada uno.
Número de libros vendidos = 360 BS / 36 BS
= 10 libros
Número de libros restantes = 40 BS - 10 BS
= 30 BS
¿Cuánto debo vender cada uno de los libros restantes para no perder ni ganar nada?
Para no ganar ni perder nada, la cantidad total que queda para vender los libros =
1200BS - 360 BS = 840 BS
La cantidad para vender cada uno de los libros restantes sin ganar ni perder nada se calcula como:
840BS / Número de libros restantes
= 840BS / 30BS
= 28BS
