Using unit concepts, it is found that:

a) Grams.
b) Grams.
c) Grams squared.
d) Grams squared.

-----------------------------

For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
The variance has the unit squared, both for the sample and the population.
For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.

-----------------------------

In this question, the data-set is in grams.

The standard deviation, both for the sample and the population, in items a and b, will be in grams.
The variance, both for the sample and the population, in items c and d, will be in grams squared.

-x + 2y = 3 2x – 3y = -6

s2008m [1.1K]

Answer:

x = -3

y = 0

Step-by-step explanation:

Given equations :- 

-x + 2y = 3 ....... ( i )

2x - 3y = -6 ....... ( ii )

From ( i ) 

-x + 2y = 3

-x = 3 - 2y

x = 2y - 3 ........ ( iii )

From ( ii ) 

2x - 3y = -6

2x = -6 + 3y

$x = \frac{ - 6 + 3y}{2}$

........ ( iv )

Equating ( iii ) and ( iv )

x = x

$2y - 3 = \frac{ - 6 + 3y}{2}$

4y - 6 = -6 + 3y

4y - 3y = -6 + 6

y = 0

Putting value of y in ( iii )

x = 2y - 3

x = 2 ( 0 ) - 3

x = -3
