Mathematics
1 answer:
miss Akunina [59]3 years ago
8 0

Step-by-step explanation:

Notice that KM = 0.5BC, KL = 0.5AC

and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.

Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)

Perimeter of 3 small purple triangles

= 3 * [24cm * (1/4)]

= 3 * 6cm = 18cm.

Hence Total perimeter of shaded parts

= 12cm + 18cm = 30cm.

In the Country A legal system, a defendant is presumed innocent until proven guilty. Consider a nullhypothesis, H0, that the def
Pie

Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

<h3>What are Type I and Type II errors?</h3>
  • Type I: Rejection of a true null hypothesis. The null hypothesis is true, but from a sample, you get enough evidence to reject.
  • Type II: Non-rejection of a false null hypothesis. The null hypothesis is false, but from a sample, you do not get enough evidence to reject.

Hence:

In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

A fence is going to diagonally divide a 30 foot by 24 foot rectangular garden in half. Approximately how long, in feet, should t
Vedmedyk [2.9K]

Answer:38

Step-by-step explanation:

The diagonal of a rectangle creates the hypotenuse of a right triangle. Use the Pythagorean theorem, a2 + b2 = c2, where a = 30 ft and b = 24 ft, to calculate the length of the fence c.

a2 + b2 = c2

302 + 242 = c2

900 + 576 = c2

1476 = c2

38.42 ≈ c

The fence should be about 38 feet long. Isn't it strange to divide a garden in half diagonally with a fence? It doesn't seem to serve the purpose of keeping intruders out. It doesn't seem to serve any purpose, really.
