Answer:
17.76 pounds
Step-by-step explanation:
The first thing we have to do is resort to the normal distribution table (attached image).
To find the smallest annual per capita consumption of ice cream that can be in the top 25% of consumption, we must find when the probability of z is equal to = 1 - 0.25 = 0.75
Find the z value when the probability 75%, i.e .:
z = invNorm (0.75) = approximately 0.675
To find the value, we apply the following formula:
x = z * sd + m
where sd is the standard deviation 3.5 and m the mean that is 15.4, knowing these values, we replace:
x = 0.675 * 3.5 + 15.4
x = 17.76
That is, the smallest annual consumption under these conditions is 17.76 pounds.
Answer:
A.
Step-by-step explanation:
Respuesta:
88,8 cm²
Explicación:
Consideremos un hexágono regular. Su apotema, la distancia más corta entre el centro del hexágono y uno de sus lados, es 3,7 cm y sus lados miden 8 cm.
Primero debemos calcular su perímetro, que es igual a la suma de sus 6 lados.
Perímetro = 8 cm + 8 cm + 8 cm + 8 cm + 8 cm + 8 cm = 48 cm
Luego, podemos calcular el área del hexágono usando la siguiente fórmula:
Area = Perímetro × Apotema / 2
Area = 48 cm × 3,7 cm / 2 = 88,8 cm²
