Suppose that the value of a stock varies each day from $10.82 to $25.17 with a uniform distribution. Find the third quartile, i.e., 75% of all days the stock is below what value

Answers

Answer 1

Answer: Third quartile =$21.58

Step-by-step explanation:

Let x be value of a stock .

For uniform distribution,

probability density function =  [tex]\dfrac{1}{b-a}=\dfrac{1}{25.17-10.82}=\dfrac1{14.35}=\dfrac{100}{1435}[/tex]

Let a be the stock value such that P(x<a) =75% or 0.75

[tex]\Rightarrow\ \int ^{a}_{10.82}f(x)\ dx=0.75\\\\\Rightarrow\ \int ^{a}_{10.82}\dfrac{100}{1435}\ dx=0.75\\\\\Rightarrow\dfrac{100}{1435}[x]^{a}_{10.82}=0.75\\\\\Rightarrow \dfrac{100}{1435}(a-10.82)=0.75\\\\\Rightarrow a-10.82=0.75\times\dfrac{1435}{100}\\\\\Rightarrow a-10.82=10.7625\\\\\Rightarrow a= 10.7625+10.82= $$21.5825\approx $$21.58[/tex]

Hence, 75% of all days the stock is below $21.58 or Third quartile =$21.58 .

Questions :

(4a) Write a multiplication equation AND a division equation to represent this statement. "There are 12 fourths in 3.".



(4b) Write a multiplication equation and a division equation to represent this diagram.

Answers

Answer:

12/4 * 3 or 3 ÷ 12/4

Step-by-step explanation:

Don't worry, I got you covered.

First, you examine the words in the sentence. After you look at the key-words, which would be "12 fourths in 3." This would translate to 12/4 into 3. Here's the examples.

Start by dividing rather than multiplying for your first equation.

3 ÷ 12/4. If you want 3 to be equal to 12/4 in division, you want to take the largest number and divide it into the smaller number. In this case, the large number would be 3 while the small number would be 12/4. It still makes it correct, despite you changing the problem a bit.

This would get you the easiest way to use your division.

Finally, try making a multiplication problem. If you want there to be 3 equal to 12/4, another justification could be 12/4 * 3. This would keep the problem true, while still solving the missing equation.

I'm 10000000000% sure

Answer:

x = 5

Step-by-step explanation:

First, to get rid of the fraction, multiply both sides of the equation by x.

— (14.8/x + 2.4) * x = 5.36 * x

— 14.8 + 2.4x = 5.36x

Next, subtract 2.4x from both sides of the equation.

— 14.8 + 2.4x - 2.4x = 5.36x - 2.4x

— 14.8 = 2.96x

Now, divide both sides of the equation by 2.96.

— 14.8/2.96 = 2.96x/2.96

— 5 = x

The rule of 72 is used to determine how long it will take an investment to . For an investment of $5,000 earning 7% annually, this will take about years.

Answers

Answer:

10.3 years

Step-by-step explanation:

The Rule of 72 is a rule used to determine the period of time it would take an investment to double at a given fixed annual rate of return. The rule of 72 helps investors to have an estimate of how long an initial investment would double. The rule of 72 is given by the formula:

t = 72 / r

where r is the annual rate of return and t is the approximate time in years required for the investment to double.

t = 72 / r

Given that r = 7%

t = 72 / r = 72 / 7 = 10.3 years

Therefore it would take 10.3 years for an investment of $5,000 earning 7% annually to double to about $10,000

Their hope was that on March 15, 2114, it would be opened and the future residents of NYC would see what life was like 100 years in the past.Locked away in the titanium cylinder were important artifacts from the present day. The objects were chosen by citizens from all walks of life and professions: librarians, teens, computer programmers, medical professionals, research scientists, gardeners, biologists, and more.Etched onto the surface of the time capsule were the words of a famous author, William Faulkner: "I believe that man will not merely endure. He will prevail.because he has a soul, a spirit capable of compassion and sacrifice and endurance."The capsule was buried with much hope for the future.Sadly, things didnt turn out as they had hoped.By March 15, 2514, New York had become a desperate place. Something big had changed. The city was in near ruins. Citizens were terrified.Two teens or kidz, as they were called now were on their way home from a secret meeting. As they walked in the shadows to avoid detection, they tripped on a huge titanium cylinder. Etched into the surface were a series of scratched-out words. The only words they could make out were, "He will prevail."The kidz dragged the heavy cylinder into a hidden alleyway and twisted it open. The glow from their flashlights revealed what was inside. With gasps of relief, they looked at each other with hope in their eyes for the first time in years.Now you will become the author and write a narrative based on the prompt. Start your story with your characters walking home and discovering the time capsule.Here are some things to consider as you fill out your organizer to plan your story:Who are the teens?
