What is the value of y in the sequence below<br> 2, У, 18,-54, 162
Maslowich

Answer:

<em>y=-6</em>

Step-by-step explanation:

<em>Geometric Sequences</em>

Any given sequence is said to be geometric if each term a_n can be obtained as the previous term a_{n-1} by a constant value called the common ratio.

a_n=a_{n-1}.r

or equivalently

a_n=a_1.r^{n-1}

Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios

\displaystyle \frac{162}{-54},\ \frac{-54}{18} and we see they both result -3. If we use r=-3 and try to find the second term (y), then

y=2*(-3)=-6

Now we compute the third term: (-6)(-3)=18

Since we got the third term as given in the original sequence.

So y=-6

¿por que en los mapas se respeta la misma escala? Ayudenme por favor esta es otra pregunta ¿qué pasaría si una parte del mapa se
7nadin3 [17]

Answer:

Ok, supón que conoces exactamente tu posición en un mapa, y también sabes a donde quieres ir.

Podes ver en ese mapa la distancia entre tu posición y el lugar al que quieres ir, ahora, si la escala del mapa es conocida (por ejemplo 1cm = 1km) y constante, entonces vos podes medir la cantidad de centímetros entre tu posición y tu destino, y multiplicar ese numero por la escala, de esta forma conociendo la distancia real entre tu posición y tu destino.

Ahora, si la escala no es constante, entonces es imposible saber exactamente la distancia entre nuestra posición y nuestro destino, entonces este mapa no sirve realmente para ubicarnos/guiarnos, entonces no funciona como un mapa.

En el caso de que una parte este en una escala y otra parte en otra, en la primera parte un centímetro en el mapa equivaldría a una distancia X en la realidad, y en la otra zona un centímetro en el mapa equivaldría a una distancia Y en la realidad.

Donde X es diferente de Y, ahora, cuando queremos calcular la distancia entre dos lugares tendríamos que saber exactamente en que lugar se da el cambio de escala (para saber si usamos X o Y). Lo que hace que leer este mapa sea bastante mas difícil que leer un mapa normal.

If the bottom row as a result of sythetic division is 1 3 0 4 0, then the quotient is which of the following? Select one:
zmey [24]

The quotient of the synthetic division is x^3 + 3x^2 + 4

<h3>How to determine the quotient?</h3>

The bottom row of synthetic division given as:

1 3 0 4 0

The last digit represents the remainder, while the other represents the quotient.

So, we have:

Quotient = 1 3 0 4

Introduce the variables

Quotient = 1x^3 + 3x^2 + 0x + 4

Evaluate

Quotient = x^3 + 3x^2 + 4

Hence, the quotient of the synthetic division is x^3 + 3x^2 + 4

A toy manufacturer wants to know how many new toys children buy each year. A sample of 305 children was taken to study their pur
Harrizon [31]

Answer:

The 80% confidence interval for the mean number of toys purchased each year is between 7.5 and 7.7 toys.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.8}{2} = 0.1

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.1 = 0.9, so Z = 1.28.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.28\frac{1.5}{\sqrt{305}} = 0.1

The lower end of the interval is the sample mean subtracted by M. So it is 7.6 - 0.1 = 7.5

The upper end of the interval is the sample mean added to M. So it is 7.6 + 0.1 = 7.7

The 80% confidence interval for the mean number of toys purchased each year is between 7.5 and 7.7 toys.
