(AP Statistics - Will give brainliest) The weight of apples at the grocery store follows a Normal distribution with a mean of μ

= 5 ounces and a standard deviation of σ = 1 ounce. Suppose we pick nine apples at random from the basket and find their total weight, W. Which of the following statements describes the random variable W?
The random variable W is Normal, with a mean of five ounces and a standard deviation of one ounce.
The random variable W is Normal, with a mean of 45 ounces and a standard deviation of three ounces.
The random variable W is Normal, with a mean of five ounces and a standard deviation of three ounces.
The random variable W is binomial, with a mean of 45 ounces and a standard deviation of nine ounces.
The random variable W is binomial, with a mean of five ounces and a standard deviation of nine ounces.

The random variable W is Normal, with a mean of 45 ounces and a standard deviation of three ounces.

<h3>How to describe the random variable?</h3>

The given parameters are:

  • Sample size, n = 9
  • Population mean, μ = 5 ounces
  • Standard deviation, σ = 1 ounce

The mean of the 9 apples is:

μ = 5 ounces * 9

This gives

μ = 45 ounces

The variance of the 9 apples is:

σ² = 1 ounces * 9

This gives

σ² = 9 ounces

Take the square root of both sides, to calculate the standard deviation.

σ = 3 ounces

Since, the variable W is normal; the description of the variable W is (b)

1) Calcula la diagonales de un poligono n lados. Heptágono: 2 puntos
ahrayia [7]

Answer:

El número de diagonales de un polígono de n lados se calcula mediante la siguiente fórmula:

d = \frac{n\cdot (n-3)}{2} (1)

Donde:

d - Cantidad de diagonales del polígono.

n - Cantidad de lados del polígono.

Bajo esta fórmula, tenemos los siguientes resultados:

a) El heptágono tiene 14 diagonales.

b) El octágono tiene 20 diagonales.

c) El eneágono tiene 27 diagonales.

d) El decágono tiene 35 diagonales.

e) El pentadecágono tiene 90 diagonales.

Explanation:

La cantidad de diagonales de un polígono se puede determinar mediante la siguiente ecuación:

d = \frac{n\cdot (n-3)}{2} (1)

Donde:

d - Cantidad de diagonales del polígono.

n - Cantidad de lados del polígono.

A continuación, calculamos la cantidad de diagonales de los siguientes polígonos:

Heptágono (n = 7)

d = \frac{7\cdot (7-3)}{2}

d = 14

El heptágono tiene 14 diagonales.

Octágono (n = 8)

d = \frac{8\cdot (8-3)}{2}

d = 20

El octágono tiene 20 diagonales.

Eneágono (n = 9)

d = \frac{9\cdot (9-3)}{2}

d = 27

El eneágono tiene 27 diagonales.

Decágono (n = 10)

d = \frac{10\cdot (10-3)}{2}

d = 35

El decágono tiene 35 diagonales.

Pentadecágono (n = 15)

d = \frac{15\cdot (15-3)}{2}

d = 90

El pentadecágono tiene 90 diagonales.

Which of the following core values are involved in the national debate regarding the surveillance program referred to in this sc
gayaneshka [121]

Answer: A) Liberty versus stability and order

Explanation:

Scenario not attached but this should be the correct answer.

In the debate about surveillance in the United States, the principles of liberty and stability and law and order seem to always clash. The bone of contention is that people should have the liberty to live life as they want without worrying about the government snooping on them.

The principle of stability and order however, calls for surveillance so that behavior that is not in the best interests of the country can be curbed.

For this reason, these two principles keep clashing in reference to surveillance.
