What's the midpoint between (1,-7) and (-1,-23)

Mathematics

Answer: (0,-15)

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

Explanation:

Add up the x coordinates to get 1+(-1) = 0. Divide this sum in half to get 0/2 = 0. Therefore the x coordinate of the midpoint is 0.

Repeat for the y coordinates. First add the y coordinates to get -7+(-23) = -30. Then divide that result in half to get -30/2 = -15. So the y coordinate of the midpoint is -15.

Overall, the midpoint is (0,-15).

A large study of German children of Caucasian descent found that 46% have brown hair and that 25% have freckles. Nonetheless, yo
STatiana [176]

Answer:

Having brown hair and having freckles are not necessarily independent events          

Step-by-step explanation:

We are given the following information in the question:

Percentage of children having brown hairs = 46%

Percentage of people children having freckles = 25%

But it cannot be concluded that

German children of Caucasian descent are brown‑haired with freckles =

0.46\times 0.25 = 0.115 = 11.5\%

This is not always true because of the following reasons:

Brown hair and having freckles are not necessarily independent events.

We can not assume that event of a child having brown hair is independent of the event of child having freckles. The events could be dependent as well.

The above will only be true when event of a child having brown hair is independent of the event of child having freckles.

If the events are independent then,

P(A \cap B) = P(A)\times P(B)
