Identify the type of data (qualitative/quantitative) and the level of measurement for the data described below. Explain your ch

ella [17]

Answer:

Option A) Quantitative, because numerical values, found by either measuring or counting, are used to describe the data

Option C) Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.

Step-by-step explanation:

We are given the following in the question:

"The average monthly rainfall in inches for a certain city throughout the year"

Qualitative or quantitative:

Quantitative data are measures of values or counts and are expressed as numbers.
Qualitative data are measures of 'types' and may be represented by a name, symbol, or a number code. They are non-parametric values.

Thus, the given quantitative data is quantitative because rainfall is always measured and the output is expressed in numerical values.

Option A) Quantitative, because numerical values, found by either measuring or counting, are used to describe the data

Level of measurement:

Ordinal: These are the qualitative variable whose order plays an important role.

Interval: When true zero does not exist. The negative values of such variables make sense.
Ratio: When true zero exist. The negative values of such variable does not make any sense.

Since,for the given data true zero exist and a negative values make no sense, thus its is ratio.

Option C) Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.

1. What is distributive property?

Ulleksa [173]

1..The distributive property is when you take the number and multiply it to the numbers in the parentheses

2.You must use the distributive property because it helps simplify difficult problems and breaks the problem down into a simpler version

3. To solve a multi step equations with parentheses you must use the addition property subtraction property distributive property in multiplication property if all are needed

En la tienda de mascotas "Animalo-T", se desea elevar un elefante de 2,900 kg utilizando una elevadora hidráulica de plato grand

Korvikt [17]

Answer:

Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.

Step-by-step explanation:

Por el Principio de Pascal se conoce que el esfuerzo experimentado por el elefante es igual a la presión ejercida por el plato pequeño. Es decir:

$\frac{F_{1}}{A_{1}} = \frac{F_{2}}{A_{2}}$ (1)

Donde:

$F_{1}$ - Fuerza experimentada por el elefante, medida en newtons.

$F_{2}$ - Fuerza aplicada sobre el plato pequeño, medida en newtons.

$A_{1}$ - Área del plato grande, medida en metros cuadrados.

$A_{2}$ - Área del plato pequeño, medida en metros cuadrados.

La fuerza aplicada sobre el plato pequeño es:

$F_{2} = \left(\frac{A_{2}}{A_{1}} \right)\cdot F_{1}$

La fuerza experimentada por el elefante es su propio peso. Por otra parte, el área del plato es directamente proporcional al cuadrado de su diámetro. Es decir:

$F_{2} = \left(\frac{D_{2}}{D_{1}} \right)^{2}\cdot m\cdot g$ (2)

Donde:

$D_{1}$ - Diámetro del plato grande, medido en centímetros.

$D_{2}$ - Diámetro del plato pequeño, medido en centímetros.

$m$ - Masa del elefante, medida en kilogramos.

$g$ - Aceleración gravitacional, medida en metros por segundo cuadrado.

Si sabemos que $D_{1} = 0.75\,m$ , $D_{2} = 0.13\,m$ , $m = 2900\,kg$ y $g = 9.807\,\frac{m}{s^{2}}$ , entonces la fuerza a aplicar al émbolo pequeño es:
