The midpoint of ABis M (0,-7). If the coordinates of A are (-2,-6), what are the coordinates of B?

DENIUS [597]

The coordinates of B will be "(2, -8)".

Given:

Midpoint of AB,

(x, y) = (0, -7)

Coordinates of A,

(x₁, y₁) = (-2, -6)

As we know,

The formula of midpoint is:

→ $X =\frac{x_1+x_2}{2}$

$0=\frac{-2+x_2}{2}$

$0=-2+x_2$

$x_2=2$

→ $Y=\frac{y_1+y_2}{2}$

$-7=\frac{-6+y_2}{2}$

$-14=-6+y_2$

$y_2=-14+6$

$y_2=-8$

hence,

→ $(x_2,y_2)=(2, -8)$

Thus the above answer is correct.

Fill in the blank. A _______ variable is a variable that has a single numerical value, determined by chance, for each outcome

sineoko [7]

Answer:

Random variable

Step-by-step explanation:

The reason it is a random variable is because a, the definition fits, and b you can use context clues as well, such as 'determined by chance' which is another example of random! So, the answer is random, because random variables are determined by chance. Hope this helped.
