Answer:

The probability a flower is AT LEAST 74 inches tall is 0.2525.

Step-by-step explanation:

Since the height is normally distributed, we can use normalcdf to solve for the probability. First, find the Z-score of 74, which is (x-mu)/standard deviation. Solving, Z=(74-72)/3, or 2/3. Using normalcdf(2/3, 10^99, 0, 1), we get the probability a flower is AT LEAST 74 inches tall to be 0.2525.

Note: If you're asking for the probability that a flower is equal to 74 inches tall, it would be 0, since individual values have no probability.

Para festeja su cumpleaños,Nancy compró 15 paquetes de pizzetas. Si cocinó 288 pizzetas, cuántos paquetes completos le quedaron?
Lorico [155]

Answer:

Nancy consumió 12 paquetes de pizzetas y le quedaron 3 paquetes completos.

Step-by-step explanation:

En primer lugar, debemos descomponer el número total de pizzas como una multiplicación de números primos. Al realizar la descomposición factorial tenemos que:

288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3

Entonces, los familia de divisores de 288 es el siguiente conjunto:

D_{288} = \{2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144 \}

Si tanto la cantidad de paquetes de pizzetas y la cantidad cocinada de pizzetas son números enteros y positivos, siendo la última mucho mayor. Entonces, la cantidad de pizzetas debe ser un número entero y la cantidad de paquetes gastados menor a la cantidad de paquetes comprados y el número entero más cercano a esa cantidad. Entonces, concluimos que Nancy se gastó 12 paquetes de pizzetas, quedándole 3 paquetes completos.
