vamos utilizar todos os 
elementos. Então P6=6!=720
Depois esses 6 candidatos serão combinados em 4 
grupos, podendo ser 2 grupos com 2 e 2 grupos com 
1; 1 grupo com 3 e 3 grupos com 1. Então C6,4= 6! / 4! 
(6-4)! = 6! /4! 2! = 6.5.4! / 2.1 = 30/2 = 15
Ficamos com 15 combinação multiplicado por 720 
permutações = 10800

28. Resposta: Errado.
Temos 12 funcionários, para:
Agência1→(4funcionários) .:. C12,4 = 12! /4!8! = 
118880/24 = 495
Para agência 2 → (12-4 = teremos 8 funcionários dis-
poníveis para combinar)
funcionários) .:. C8,4= 8! / 4! 4! = 1680/24 = 70
Para agência3→(4funcionários) .:. C4,4= 1
Então: 495 . 70 . 1 = 34.650
29. Resposta: Letra D.
Sabemos pelo enunciado que a variância está em me-
tro quadrado, logo a unidade dos dados da amostra é 
medida em metros. 
Os quartis são medidas de posição (neste caso em 
metros), e o coeficiente de variação não tem unidade, 
pois o mesmo é a divisão do desvio padrão pela média 
e essas duas quantidades possuem a mesma unidade 
de medida, assim ao fazer a divisão, a unidade de me-
dida é eliminada.
Logo, esses dois valores caracterizam-se, respectiva-
mente, por possuir unidade de medida m e ser adi-
mensional.
30. Resposta: Letra E.
O modelo de regressão linear simples é dado por Y = 
aX + b
Em que Y é a variável dependente, a é o coeficiente 
angular da reta e b (coeficiente linear) é a inteceptação 
da reta no eixo vertical (Y).
Substituindo pela transformação dada na questão:
Y - Média (Y)/ desvio (Y) 
= (aX + b) - Média / desvio (Y)
= aX/ desvio + b/desvio - Média/desvio

World Bank Brazil – country brief
1 With an estimated 167 million inhabitants, Brazil has 
the largest population in Latin America and ranks sixth 
in the world. The majority live in the south-central area, 
which includes industrial cities
4 such as São Paulo, Rio de Janeiro and Belo Horizon-
te. 80% of the population now lives in urban areas. Rapid 
growth in the urban population has aided economic de-
velopment but also created serious
7 problems for major cities. Brazil’s “miracle years” 
were in the late 1960s and early 1970s when double di-
git-annual growth rates were recorded and the structure
10 of the economy underwent rapid change.
In the 1980s, however, Brazil’s economic performance 
was poor in comparison with its potential. Annual Gross 
Domestic Product
13 (GDP) growth only averaged 1.5 percent over the 
period from 1980 to 1993. This reflected the economy’s 
inability to respond to international events in the late 
1970s and the 1980s: the second oil
16 shock; increase in international real interest rates; 
the Latin American external debt crisis and the ensuing 
cutoff of foreign credit and foreign direct investment. 
This lack of responsiveness reflected the largely
19 inward-looking policy orientation that had been in 
place since the 1960s.
Economic flexibility was further impaired by provi-
sions of the
22 1988 Constitution, which introduced significant 
rigidities in budgeting and public expenditure. An out-
come of these pressures was a steady rise in the rate of 
inflation, which reached monthly rates of 50% by the
25 middle of 1994.
