Answer:
a) 0.11
b) 60
Step-by-step explanation:
Total frequency:
12+35+11+23+7+12 = 100
P(3) = 11/100 = 0.11
P(6) = 12/100 = 0.12
Expected no. of sixes:
500 × 0.12 = 60

Answer:
47.84%
Step-by-step explanation:
The easiest method to solve this exercise is to assume that the starting diesel price is 100 reais.
Now we will calculate each increase with our assumption:
1. Initial price plus 10% increase, therefore:
100 + 100 * 0.1 = 110 reais
2. Additional 20% increase in relation to 110 reais:
110 + 110 * 0.2 = 132 reais
3. Additional 12% increase in relation to 132 reais:
132 + 132 * 0.12 = 147.84 reais.
What it means is that the price would be 147.84 reais.
Since our assumption is 100, we can know that there was an increase of almost 47.84% in relation to the initial price that we assumed at the beginning.
Answer:
60%
