Responda:
R $ 15.600
Explicação passo a passo:
Deixe a dívida inicial = x = 100%
% pago = 20% = 0,2x
% esquerda =. 100% - 20% =. 80% = 0,8x
35% da dívida restante = 0,35 * 0,8x = 0,28x
Conseqüentemente,
0,28x = 4368
x = 4368 / 0,28
x = R $ 15.600
Logo, o valor inicial da dívida = R $ 15.600

Answer:
The number of plans that cost between $52.38 and $96.7 is 913.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of $74.54, standard deviation of $11.08
Percentage of plans that cost between $52.38 and $96.7.
52.38 = 74.54 - 2*11.08
96.7 = 74.54 + 2*11.08
Within 2 standard deviations of the mean, so by the Empirical Rule, 95%.
The number of plans that cost between $52.38 and $96.7 is .
95% of 961. So
0.95*961 = 913
The number of plans that cost between $52.38 and $96.7 is 913.
