En un día de febrero, una ciudad de Estados Unidos registró una temperatura mínima de 9° bajo cero y una temperatura máxima de 1
____ [38]

Answer:

La cantidad de grados del intervalo de temperaturas registradas en el día de febrero mencionado es de:

  • <u>5</u>

Step-by-step explanation:

En estadística, cuando se utilizan intervalos como valores para identificar datos cuantitativos, como en este caso temperaturas registradas, deben tomarse todos los valores, en este caso enteros, desde el límite inferior (temperatura mínima) hasta el límite superior (temperatura máxima), por lo cual no se puede restar el valor máximo al valor mínimo, sino que debes identificar todos los valores y después contarlos. En el caso del ejercicio dado, los grados en el intervalo mencionado son:

  1. 9°C
  2. 10°C
  3. 11°C
  4. 12°C
  5. 13°C

Como puedes ver, los grados en el intervalo de temperaturas registradas serían 5.

Answer:

112°

Step-by-step explanation:

By inscribed angle theorem:

m\widehat {BCD} = 2\times m\angle BAD\\\therefore m\widehat {BCD} = 2\times 129\degree \\\therefore m\widehat {BCD} = 258\degree\\\\\because m\widehat{CD} = m\widehat {BCD}-m\widehat{BC} \\\therefore m\widehat{CD} = 258\degree - 146\degree \\\huge \red {\boxed {\therefore m\widehat{CD} = 112\degree}}
