Answer:
Step-by-step explanation:
A histogram or a bar graph is used to show the big data having frequencies on the y-axis and range in which the data lie on x-axis.
In the given histogram there is no range of data.
Only percentage of customers who are satisfied with the different types of trucks have been given.
Therefore, to represent this data pie chart should be used instead of a histogram.
Answer:
Step-by-step explanation:
<em>START:</em> 4x + 10 = - 26 ⇔ 4x = - 36 ⇔ <em>x = - 9</em>
x + 13 = 9 ⇔
x = - 4 ⇔ <em>x = 8</em>
x - 9 = 27 ⇔
x = 36 ⇔ <em>x = 48</em>
9 - 2x = 35 2x = - 35 + 9 ⇔ <em>x = - 13</em>
x + 15 = 17 ⇔
x = 2 ⇔ <em>x = 3</em>
- 5x - 10 = 10 ⇔ 5x = - 20 ⇔ <em>x = - 4</em>
Now is your turn. You can do it!!!

Answer:
The probability the man was hit by a Blue Cab taxi is 41%.
Step-by-step explanation:
In terms of bayesian probability, we have to calculate P(B|Wr), or, given the witness saw the right colour, the taxi is from the Blue Cab company.
According to Bayes
P(B|Wr) = P(Wr|B)*P(B)/P(Wr)
P(Wr|B) = 0,8
P(B) = 0.15
To calculate P(Wr), or the probability of the witness of guessing right, we have to consider the two possibilities:
1) The taxi is from Blue Cab (B) and the witness is right (Wr).
2) The taxi is from Green Cab (G) and the witness is wrong (Ww).
The total probality of guessing right is
P(B)*P(Wr) + P(G)*P(Ww) = 0.15*0.8 + 0.85*0.2 = 0.29
So we can calculate:
P(B|Wr) = P(Wr|B)*P(B)/P(Wr) = 0.8*0.15/0.29 = 0.41
The probability the man was hit by a Blue Cab taxi is 41%.
