Hey I have a link to the question since its kinda complicated

Natalija [7]

Anyway

so the recursive rule tells the relationship between the previous term and the term we want to find

given

an=2n+11
it is clear that the first term is 13
2nd term is 15
3rd term is 17

each term increases by 2
so
a term is equal to the previous term plus 2
an=a(n-1)+2

the first one is the answer

Step-by-step explanation

Move the decimal to the right until it's a single digit number, because you are moving it to the right, it would be a negative number. If you are able to round up then please do. Remember to check your significant figures if you're in chemistry.

Answer:

Un batido de proteínas cuesta $ 5,25.

Step-by-step explanation:

El sistema de ecuaciones descrito al final del enunciado coincide con lo descrito al comienzo del mismo, de modo que podemos concentraron casi exclusivamente en la resolución del sistema en cuestión, la cual se describe a continuación:

Este es el sistema a resolver:

$x + 4\cdot y = 25,50$ (1)

$3\cdot x + 2\cdot y = 24,00$ (2)

Donde $x$ es el coste de un batido de fresa y $y$ corresponde al coste de un batido de proteínas:

1) Despejamos $x$ en (1):

$x = 25,50 - 4\cdot y$

2) Eliminamos $x$ en (2):

$3\cdot (25,50 - 4\cdot y) + 2\cdot y = 24,00$

$76,50 - 12\cdot y +2\cdot y = 24,00$

3) Simplificamos y despejamos $y$ :

$10\cdot y = 52,50$

$y = 5,25$

Un batido de proteínas cuesta $ 5,25.

Answer:

The answer is "96.864 ml".

Step-by-step explanation:

In this question, the formula of $\bold{CI = X \pm t \times s}$ .

( where X is the mean, t is the coefficient, and s is the mean difference error)

As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is $t=1.96$ .
