Find the area of the rhombus.
Goshia [24]

Step-by-step explanation:

as the graphic shows, we are dealing with a special rhombus : a square.

this is proven by the fact that the angle on one side of the diagonal at the corner is 45°. so, the other side must be 45° too, and so we have 90° angles at the corners.

what is not clear to me is : what is 6 cm long ? a half-diameter, or the whole diameter ?

I assume the half-diameter.

what the graphic is trying to suggest is that we have 4 little right-angled triangles that are also isoceles triangles (their legs are equally long).

every leg is 6 cm long (based on my assumption above).

because they are right-angled, the area of each of these little triangles is leg×leg/2

6×6/2 = 18 cm²

we have 4 triangles, so the total area is

4×18 = 72 cm²

if 6 cm stands for the whole diagonal after all, then the only change is the length of the legs, which would be then 6/2 = 3 cm.

then we would have

3×3/2 = 4.5 cm² for a single triangle

and

4×4.5 = 18 cm² for the whole area.

Which of the following is NOT a common characteristic of a binomial distribution?
eimsori [14]

Answer:

You should perform x trials until you observe a success.

Step-by-step explanation:

By process of elimination:

A binomial experiment is a statistical experiment that must meet certain requirements:

Each outcome is either a success (P) or a failure (Q).

All trials are independent.

There are a fixed number of "n" trials.

The probability of success, p, is the same for each trial.
