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:
3 times
Step-by-step explanation:
Given
18-white socks
18 blue socks
36 socks total
First time reached in,
18/36 ( =1/2=(50%)) chance of getting a white sock, 18/36 (=1/2=(50%)) chance of getting a blue sock
assuming you got a white sock,
17-white socks
18-blue socks
35 socks left in
Second time reached in,
17/35 (<1/2=(50%)) chance of getting a white sock, 18/35 (>1/2=(50%)) chance of getting a blue sock
You would be more likely to get a blue sock, assuming you did,
17-white socks
17-blue socks
34 socks left
Third time reached in,
17/34(=1/2=(50%)) chance of getting a white sock, 17/43(=1/2(50%)) chance of getting a blue sock
Regardless of what sock is picked you would have a matching pair of socks in hand
Boys: x
gilrs: y
From the text of the task:

Replacing x:

So there are 28 girs and 20 boys
(2-5i)(4+7i)=2(4+7i)-5i(4+7i)=8+14i-20i-35i²
recall that i²=-1,
8-6i+35=43-6i
43-6i is the final answer
