Answer:
import pandas as pd
vec = pd.Series([7.12,24,4,18,12,9])
vec.plot(kind = 'hist')
Step-by-step explanation:
You can use python for that.
By doing
import pandas as pd
vec = pd.Series([7.12,24,4,18,12,9])
vec.plot(kind = 'hist')
And this is the result you get
Answer:
b. -x + y = 0
Step-by-step explanation:

<u>Direct variation</u>:
Direct variation means "y varies directly as x”:
where k is the (non-zero) constant of variation.
To determine which of the given equations represents a direct variation, isolate y for each and compare with the <u>direct variation equation</u>.
<u>Equation a</u>
This is not a direct variation equation as there is an addition of -2.
<u>Equation b</u>
This is a direct variation equation where the constant of variation is 1.
<u>Equation c</u>
This is not a direct variation equation as y is <u>inversely proportional</u> to x.
<u>Equation d</u>
This equation does not include the variable x, and so is therefore not a direct variation equation.
