Se corta una manzana en 12 partes, se comen ocho partes. Qué fracción simplificada a su mínima expresión representa la cantidad
lakkis [162]

Answer:

A. 1/3

Step-by-step explanation:

Dado que:

una manzana se corta en 12 partes y se comen ocho partes.

La fracción de manzanas consumidas = 8/12

= 2/3

La fracción de manzanas que quedan = valor original de la manzana que se corta - la fracción de la manzana que se come

La fracción de manzanas que quedan  =1-  \dfrac{8}{12}

La fracción de manzanas que quedan  =\dfrac{12-8}{12}

La fracción de manzanas que quedan =\dfrac{4}{12}

A la fracción más baja; obtenemos = 1/3

IQ scores are known to be normally distributed. The mean IQ score is 100 and the standard deviation is 15. The top 25% of the po
aev [14]

Answer:

110

Step-by-step explanation:

We have been given that the mean IQ score is 100 and the standard deviation is 15.

We will use normal distribution table to solve our given problem.

The top 25% of the population will represent scores greater than 75%.      

The z-score corresponding to data greater than 75% is 0.6745.

Upon substituting our given values in z-score formula, we will get:

z=\frac{x-\mu}{\sigma}

0.6745=\frac{x-100}{15}

0.6745*15=\frac{x-100}{15}*15

10.1175=x-100

10.1175+100=x-100+100

110.1175=x  

Therefore, the top 25% of the population (ranked by IQ score) have IQ’s above 110.
