With the ratio at 1:1, Point C appears to be the midpoint. Use the midpoint formula to ascertain (make sure of) whether Point C

Mila [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete because the coordinates of A, B and C were not given in the question.

However, the following explanation will guide you...

The midpoints, C of two point A and B is calculated as:

$C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})$

Where $(x_1, y_1)$ are the coordinates of A

and

$(x_2,y_2)$ are the coordinates of B

Take for instance, the given coordinates are

A(4,6); B(2,4) and C(3,5)

Then;

Plug in these values in the given formula:

$C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})$

$(3,5) = (\frac{4 + 2}{2}, \frac{6 + 4}{2})$

$(3,5) = (\frac{6}{2}, \frac{10}{2})$

$(3,5) = (3,5)$

In that case,

C is really the midpoint

To the b part: Explaining why ratio 1:1 is used

The reason is that both parts of the ratio are in equal proportion (1 and 1);

Because of this equal proportion, ration 1:1 is right to calculate the midpoint

A single die is rolled twice. Find the probability of getting a 2 the first time and a 2 the second time.

Mkey [24]

Answer:

$\frac{1}{36}$

Step-by-step explanation:

The probability of rolling 2 is $\frac{1}{6}$

And rolling another 2 is $\frac{1}{6}$

$\frac{1}{6}$ × $\frac{1}{6}$

= $\frac{1}{36}$

Sorry if its wrong
