A pension fund manager is considering three mutual funds. the first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a t-bill money market fund that yields a sure rate of 5.5%. the probability distributions of the risky funds are:
The probability computed about the pension fund manager indicates that the standard deviation of the portfolio is 21.93%
How to calculate probability?From the complete information, the covariance between fund returns will be:
= 34% × 25% × 0.11
= 0.9350%
The weight of the bond fund is given as 0.407281. Therefore, the weight of the stock fund in portfolio will be:
= 1 - 0.407281
= 0.592719
Therefore, the standard deviation will be:
= 23.56% × 0.9309471
= 21.93%

Why is it difficult to study early human societies
Answer:
Before the advent of writing, historians had fewer and less detailed resources to work with
Explanation:
Writing is a system of graphic representation of a language, by means of signs drawn or engraved on a medium. In this sense, writing is a specifically human graphic way of conserving and transmitting information.
The hieroglyphic writings are the oldest of the scriptures proper (for example, the cuneiform writing was first hieroglyphic until certain hieroglyphs were attributed a phonetic value) and are observed as a transition between pictograms and ideograms. Hieroglyphic writing was abandoned in the Hellenizing period of Egypt. At present, Chinese and Japanese writing preserve some logograms combined with signs whose interpretation is purely phonetic. Most of the writings of the world are purely graphemic, so the roman scriptures (based on the Latin alphabet), Arabic (based on the Arabic alphabet), Cyrillic (based on the Greek alphabet), Hebrew (based on the Hebrew alphabet) , Hellenic (based on the Greek alphabet), Indian (generally based on the Devanāgarī) and to a much lesser extent the Armenian, Ethiopian alphabetic (abugidas based on ghez or ge'ez), Korean, Georgian, Burmese, Coptic, etc. . The Glagolitic alphabets and the runic alphabet that preceded the Gothic script as well as the Pahlavi and Zend used in today disappeared languages.

What affects the distribution of metals and minerals on earth
Answer:
This is due to the unequal resource distribution across the land and the distribution of resources depends upon the physical factors like the land and the climatic conditions. Some places are filled with more resources while some are filled with scare resources. The countries which have more resources are wealthy while the countries which do not have that much resources are not wealthy. The metals are also unevenly distributed on the earth’s crust and the most abundant metal is aluminum and silicon. Some of the distracted metals which are found deep in the earth’s crust and then extracted in the ore form from the mines. The most important reason for the uneven distribution of metals in Earth's crust are their physical factors like the climate, land and their topography.
Explanation:
Earth is made up of many minerals and metals. They are distributed unevenly because of the varying topography and climate across the lithosphere.
What is unequal distribution?Earth is made of varying minerals and metals that are found in the mantle layer and vary in quantity as the distribution, pressure, and other physical factors are different in regions.
The topographical structure, climate, and land vary the mineral and metal distribution. Some areas have suitable climates, and pressure that supports more minerals making them rich than others.

What is the oxidation number for bromine in the molecule h2br2o6
Taking into account the definition of oxidation number, the oxidation numbers for bromine in the molecule H₂Br₂O₆ is +5.
Definition of oxidation numberThe oxidation number is the charge that an atom has; is an integer that represents the number of electrons an atom puts into play when it forms a given compound.
In other words, the oxidation number of an element is a value that indicates the number of electrons that element gains or loses when it combines with another.
Oxidation number determinationTo determine the oxidation state of different elements it is necessary to know that:
The oxidation number of hydrogen in a compound is +1, except in metal hydrides, where is –1.The oxidation number of oxygen in a compound is –2, except in peroxides, where it is –1.On the other side, the sum of the oxidation numbers of the existing elements in a chemical formula must add up to zero.
Then, considering the oxidation numbers of each element, multiplying it by the number of existing elements in the chemical formula and adding it and equaling it to zero, the value of the missing oxidation number can be obtained.
Oxidation number for bromineIn this case, the oxidation numbers of bromine is calculated as:
H₂Br₂O₆: 2× (+1) + 2× (oxidation numbers of nitrogen) + 6×(-2)= 0
2 + 2× (oxidation numbers of nitrogen) - 12= 0
2× (oxidation numbers of nitrogen) - 10= 0
2× (oxidation numbers of nitrogen) =10
oxidation numbers of nitrogen= 10÷2
oxidation numbers of nitrogen= +5
Finally, the oxidation numbers for bromine in the molecule H₂Br₂O₆ is +5.

At 15°c, the value of kw is 4. 5 × 10⁻¹⁵. What is the equilibrium concentration of oh⁻ at this temperature?
The equilibrium concentration of OH⁻ at this temperature is 6.708 × 10⁻⁸ M
Ionic product of waterThe ionic product of water Kw = [H⁺][OH⁻] where
[H⁺] = hydrogen ion concentration and [OH⁻] = hydroxide ion concentration.At equilibrium, [H⁺] = [OH⁻]
So, [H⁺][OH⁻] = Kw
[OH⁻][OH⁻] = Kw
{OH⁻}² = Kw
Taking square root of both sides, we have
√{OH⁻}² = √Kw
Equilibrium concentration of OH⁻{OH⁻} = √Kw
Since Kw at 15 °C is 4. 5 × 10⁻¹⁵, substituting the value of the variable into the equation, we have
{OH⁻} = √Kw
{OH⁻} = √(4. 5 × 10⁻¹⁵)
{OH⁻} = √(45 × 10⁻¹⁶)
{OH⁻} = √45 × √10⁻¹⁶
{OH⁻} = 6.708 × 10⁻⁸ M
So, the equilibrium concentration of OH⁻ at this temperature is 6.708 × 10⁻⁸ M
