Answer:
4 = the top row would be 1,2,3,4,5
the bottom row would be 14,28,42,56,70
the equation is y= 14x
5 = yes it is proportional. y=21x
6 =no it is not proportional.
7 = yes it is proportional because y= 7x
Step-by-step explanation:
Answer:
Solution → (3, -1)
Step-by-step explanation:
We ave to identify the graph representing the system of lines first.
y = 
Y-intercept of the line = -3
y = -2x + 5
y-intercept of the line = 5
From the given graphs 3rd (extreme right) graph is representing the system of equations.
Solution of the system of equations will be the point of intersection of these lines.
Solution of the system → (3, -1)
2x - 5 < 7
2x = 12
x = 6
4x + 10 > 6
4x = - 4
x = - 1
( - 1 , 6 )

The MOST accurate definition of standard deviation is the mean absolute deviation of the sum of the squared deviation from the average. Option 4
<h3>Definition of standard deviation</h3>
Standard deviation can be defined as a statistic tool that measures the dispersion of a dataset in relation to its mean and is calculated as the square root of the available variance of the set.
It is calculated as the square root of the given variance.
Thus, the MOST accurate definition of standard deviation is the mean absolute deviation of the sum of the squared deviation from the average.
