difference between standard deviation and mean deviation
Answer:
Standard deviation is basically used for the variability of data and frequently use to know the volatility of the stock. A mean is basically the average of a set of two or more numbers. Mean is basically the simple average of data
Hope this helps!!

Answer: (d)
Step-by-step explanation:
Given
The digit 9 in the number 593,104 is at the ten-thousandths place and the value which is 10 times its value must be at lakh place.
Matching with highest place values in the option
(a) Ten-thousand place
(b) Thousand place
(c) Ten-thousand place
(d) lakh Place
Therefore, (d) is the correct option.
The measures of 2 vertical angles are always equal, so we have:
7x+182=9x+192.
Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x.
Thus, x=-6.
This means that the angles are:
i) 7x+182=7(-6)+182=182-42= 140(degrees).
ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)
Answer: x=-6</span>
Answer:
The solution of the system is at point (1,6) and (7,0).
Step-by-step explanation:
Given : System of equation
and 
To find : Solve the system of equation?
Solution :
We solve the equation graphically as the intersection points give you the solution of the system.
The equation given is one linear and one parabolic.
(1)
is a linear equation in red line passes through (0,7) and (7,0).
(2)
is a parabolic equation in blue line passes through (-1,0) and (7,0)
The intersection point of the equations are (1,6) and (7,0).
<u>Refer the attached figure below.</u>
Therefore, The solution of the system is at point (1,6) and (7,0).
The third one is the correct answer I think
