Answer:
El área del foso es 5.5 m²
Step-by-step explanation:
Hola!
Por favor, mira el esquema adjunto para una descripción del problema.
Viendo la figura, podemos deducir que el área del foso será igual al área del rectángulo formado por el jardín y el foso menos el área del jardín.
Área del foso = área del foso y jardín - área del jardín.
El área de un rectángulo se calcula multiplicando la longitud de la base por la altura:
Área del jardín = 2.5 m · 2 m = 5 m²
Área del rectángulo jardín - foso = 3.5 m · 3 m = 10.5 m²
Área del foso = 10.5 m² - 5 m² = 5.5 m²
El área del foso es 5.5 m²
Answer:
50% of females do not satisfy that requirement
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If a college includes a minimum score of 900 among its requirements, what percentage of females do not satisfy that requirement
This is scores lower than 900, which is the pvalue of Z when X = 900.
So
has a pvalue of 0.5
50% of females do not satisfy that requirement
