Answer:
The correlation coefficient is r = 0.52
Step-by-step explanation:
From the question we are told that
The correlation coefficient is r = 0.52
Generally correlation has no unit and is not affected by unit (i.e it show the ratio between two quantities )
Hence a change of the unit of measurement of length from cm to mm will not affect the correlation coefficient r hence the value will still remain r = 0.52
Answer:
El total que la señora Rina pagó por sus frutas, en términos de b, es:
Step-by-step explanation:
Para resolver este ejercicio, primero sacaremos las variable que nos brindan:
- Costo de la pera = b
- Costo de la manzana = b - 7 (esto se debe a que la manzana cuesta 7 pesos menos que la pera, tal como dice el enunciado).
Ahora, nos centraremos en la compra realizada por la señora Rina, donde se menciona que:
- <em>Compra de la señora Rina = 4 peras + 1 manzana</em>
Ahora, como si esto fuera una ecuación, vamos a reemplazar las manzanas y las peras por las variables que tenemos de su costo:
- Compra de la señora Rina = 4b + b - 7
Y procedemos a operar:
- <u>Compra de la señora Rina = 5b - 7</u> (sumando 4b + b)
Por lo tanto, <u><em>la compra de la señora Rina, en términos de b, le ha costado 5b - 7</em></u>.

Answer:
Option e is correct, as the length of legs are 10
none of these
Step-by-step explanation:
In 45-45-90 special triangle:
The length of the hypotenuse is times the length of a leg.
As per the statement:
The hypotenuse of a 45-45-90 right triangle is units.
then by definition:
Substitute the given values we have;
Divide both sides by we get;
Therefore, the length of legs are 10
