The expected value is the sum of products of probability and value.
.. 0.40*(-$25000) +0.25*($0) +0.35*($25000) = -$1,250
The expected value is a loss of $1250.
Answer:
the price of the computer is $889
Explanation:
The computation of the price of the computer is shown below:
As we know that
Z-score = (x-mean) ÷ standard deviation
-0.8 = (x - 949) ÷ 75
x = -0.8 × 75 + 949
= -60 + 949
= $889
Hence, the price of the computer is $889
We simply applied the above formula so that the correct value could come
Answer:
5 cm
Explanation:
First, let's find the perimeter of the rectangle.
The perimeter of a rectangle is:
p=2l+2w
In this rectangle, we know that the length is 7 centimetres and the width is 3 centimetres.Therefore, we can substitute 7 in for l and 3 for w.
p=2(7)+2(3)
Multiply 2 and 7
p=14+2(3)
Multiply 2 and 3
p=14+6
Add 14 and 6
p=20
We know the perimeter of the rectangle is 20 centimeters. We also know that the perimeter of the square is equal to the perimeter of the rectangle.
The perimeter of a square is:
p=s+s+s+s or p=4s
We know that the perimeter of the square is equal to the rectangle. The rectangle's perimeter is 20. Therefore, we can substitute 20 in for p.
20=4s
Now, we want to find what the side length is. We have to get s by itself. 4 and s are being multiplied. To reverse this, divide both sides by 4.
20/4=4s/4
20/4=s
5=s
The side length of the square is 5 centimeters.
The correct answer is - all of these contributed.
The sediments in the lagoons come from multiple different sources. The rivers and streams from the mainland, the sediments brought by the wind, and even the ocean waves that manage to get over the spit occasionally.
The biggest influence in the deposition of the sediments in the lagoons though is by the rivers and the streams from the mainland. They carry sediments with them constantly, and the amount of those sediments is also on a high level, in fact they bring in so much sediments that they have actually built the lagoon itself.
The wind and the ocean waves that manage to get over the spit have much lesser influence in the total deposition of sediments, but still they do in some part, and it shouldn't be put aside.
The combination of the three different sources, with different types of sediments brought to the lagoon by each of them, gives the lagoons a beautiful and unique appearance.
Answer:
Ecumene is a term used by geographers to mean inhabited land. It generally refers to land where people have made their permanent home, and to all work areas that are considered occupied and used for agricultural or any other economic purpose.
Explanation:
The ecumene (US) or oecumene (UK; Greek: οἰκουμένη, oikouménē, lit. "inhabited") was an ancient Greek term for the known, the inhabited, or the habitable world. Under the Roman Empire, it came to refer to civilization as well as the secular and religious imperial administration. In present usage, it is most often used in the context of "ecumenical" and describes the Christian Church as a unified whole, or the unified modern world civilization. It is also used in cartography to describe a type of world map (mappa mundi) used in late Antiquity and the Middle Ages.
