Answer: its always

Step-by-step explanation:

If a point lies in between two end points of a line then the sum of distance between the points in between is always equal to the whole line.

If A is in between two points B and C then the sum of line segments BA and AC will always equal to the length of BC.

Or BA+AC=BC in all cases whatever be the position of point A between the points Band C.

Always is the right option.

2x^2 / x^2 - y^2 - x^2 / xy - y ^ 2

Juliette [100K]

Answer:

2 - 2y^2 - x/y

Step-by-step explanation:

2x^2/x^2 = 2

and

x^2/xy = x/y

therefore

2x^2/x^2 - y^2 - x^2/xy - y^2

= 2 - y^2 - x/y - y^2

= 2 - y^2 - y^2 - x/y

= 2 - 2y^2 - x/y

Mila [183]

Answer:

The test hypothesis is :

$H_0: \mu=1502.5\\ H_a: \mu>1502.5$

Step-by-step explanation:

Consider the provided information.

Null hypothesis refer the population parameter is equal to the claimed value.

If there is no statistical significance in the test then it is know as the null which is denoted by $H_0$ , otherwise it is known as alternative hypothesis which denoted by $H_a$ .

The historical average lifetime for cartridges produced by the current process is 1502.5 pages.

Hence, the test hypothesis is :

$H_0: \mu=1502.5\\ H_a: \mu>1502.5$
