Proportional relationship
We know a proportional relationship is when one of the variable is obtained by multiplying the other variable by a constant number.
For example, in an equation it can be represented:
<em>y = 2x</em>
<em />
In a table, we can represent it by
<em />
In a graph,
Answer: all of them
Answer:
Step-by-step explanation:
Use the coordinates of the given points to find the slope.
difference in y-coordinates = -3 - 6 = -9
difference in x-coordinates = 2 - (-1) = 3
slope = -9/3 = -3
Answer:
18
Step-by-step explanation:
The distribution lies within one of the standard of deviation of the mean so <span>68% </span>
The distribution lies within two of the standard of deviations of the mean so 95%
The distribution lies within three of the standard of deviations of the mean so 99.7%
3420°
explanation:
the equation of the sum of interior angles are (n-2)x180
polygon above has 21 sides so you sub n as 21 and plug the equation in the calculator
