On a given day, a particular raccoon will eat the trash from one of three different houses. If he eats from the trash of a particular house, he has a 50% chance to eat from the same house the next day, and a 25% chance each to eat from one of the other two houses. What is the stochastic matrix for this scenario
Answer:
Step-by-step explanation:
On a given day , a particular raccoon will eat the trash from one of three different houses.
Let assume \(Y_n\) be a random variable that illustrating the house raccoon will eat on an unknown given nth day.
If he eats from the trash of a particular house, he has a 50% chance to eat from the same house the next day, and a 25% chance each to eat from one of the other two houses.
There are three states given in the above statement.
So, we can have state 1, state 2 and state 3
Assuming that:
state 1 = house 1
state 2 = house 2
state 3 = house 2
If he eats from the trash of a particular house,
For state 1 : he has a 50% chance to eat from the same house the next day
i.e state 1 = 0.50
and a 25% chance each to eat from one of the other two houses.
For state 2 and state 3: = 0.25
i.e state 2 = 0.25
state 3 = 0.25
NOW:
\(\mathtt{P[Y_{n+1 }= 0 \ | \ Y_n = 0] = 0.5}\)
\(\mathtt{P[Y_{n+1 }= 1 \ | \ Y_n = 0] = 0.25}\)
\(\mathtt{P[Y_{n+2}= 2 \ | \ Y_n = 0] = 0.25}\)
\(\mathtt{P[Y_{n+1 }= 0 \ | \ Y_n = 1] = 0.25}\)
\(\mathtt{P[Y_{n+1 }= 1 \ | \ Y_n = 1] = 0.5}\)
\(\mathtt{P[Y_{n+1 }= 2 \ | \ Y_n = 1] = 0.25}\)
\(\mathtt{P[Y_{n+1 }= 0 \ | \ Y_n = 2] = 0.25}\)
\(\mathtt{P[Y_{n+1 }= 1 \ | \ Y_n = 2] = 0.25}\)
\(\mathtt{P[Y_{n+1 }= 2 \ | \ Y_n = 2] = 0.5}\)
The stochastic matrix for this scenario can be computed as:
0 1 2
\(P = \left\begin{array}{c}0\\1\\2\end{array}\right \left[\begin{array}{ccc}0.5&0.25&0.25\\0.25&0.5&0.25\\0.25&0.25&0.5\end{array}\right]\)
\(\mathbf{ P =\left[\begin{array}{ccc}0.5&0.25&0.25\\0.25&0.5&0.25\\0.25&0.25&0.5\end{array}\right] }\)

Bill and Jack are the only two owners of a sandwich shop. Bill invested $20,000 and Jack invested $28.000. al What percent of the company does Jack own? Round to the nearest whole percent. b) What is the ratio of Bill's ownership to Jack's ownership?
Answer:
The percentage is 17% and the rotio is 7.5
Step-by-step explanation:
(a) 28000-20000=8000.
(8000/28000+20000)*100%
=16.66%=17%
(b) (28000/48000)
= 7/12.
(20000/48000)
=5/12.
so you take the numerators which are 7 and 5.so the ratio is7.5
The concentration of dichlorodiphenyltrichloroethane (DDT - an infamous pesticide) in Lake Michigan has been declining exponentially over many years. In 1971, the DDT concentration was 13.00 ppm (parts per million). In 1984, the DDT concentration was 2.22 ppm.
Using these data points, determine the exponential decay function to model the DDT concentration decline in terms of years, tt, where t=0t=0 represents the year 1971.
A) Write your function as y = Ce^{rt}y=Ce^rt. Round your value of rr to four decimal places.
B) Another way to write the function down is known as the half-life formula, written as y = C(0.5)^{t/H}y=C(0.5)^t/H, where HH is the time required for the concentration to get cut in half. Using the initial two data points, find the value of HH, rounded to 2 decimal places. Show all Algebraic work.
C) The goal was to reduce the DDT concentration to 0.98 ppm by 1995. Was this possible according to your model?
Answer: A) \(y=13e^{-0.1359t}\)
B) H = 5.10
C) Yes
Step-by-step explanation: Exponential Decay function is a model that describes the reducing of an amount by a constant rate over time. Generally, it is written in the form: \(y(t)=Ce^{rt}\)
A) C is initial quantity, in this case, the initial concentration of DDT. To determine r, using the data given:
\(y(t)=Ce^{rt}\)
\(2.22=13e^{13r}\)
\(e^{13r}=0.1708\)
Using a natural logarithm property called power rule:
\(13r=ln(0.1708)\)
\(r=\frac{ln(0.1708)}{13}\)
\(r=-0.1359\)
The decay function for concentration of DDT through the years is \(y(t)=13e^{-0.1359t}\)
B) The value of H is calculated by \(y=C(0.5)^{\frac{t}{H} }\)
\(2.22=13(0.5)^{\frac{13}{H} }\)
\((0.5)^{\frac{13}{H} }=0.1708\)
Again, using power rule for logarithm:
\(\frac{13}{H} log(0.5)=log(0.1708)\)
\(\frac{13}{H} =\frac{log(0.1708)}{log(0.5)}\)
\(\frac{13}{H} =2.55\)
H = 5.10
Constant H in the half-life formula is H=5.10
C) Using model \(y(t)=13e^{-0.1359t}\) to determine concentration of DDT in 1995:
\(y(24)=13e^{-0.1359.24}\)
y(24) = 0.5
By 1995, the concentration of DDT is 0.5 ppm, so using this model is possible to reduce such amount and more of DDT.

Answer:
\(V=6x^3+3x^2\)
Step-by-step explanation:
The given figure shows a cuboid whose length is (2x+1) breadth is x and height is 3x.
We need to find the volume of the three dimensional figure.
The volume of a cuboid is given by :
V = lbh
Substitute all the values,
\(V=(2x+1)\times x\times 3x\\\\V=(2x+1)\times 3x^2\\\\= 3x^2(2x)+3x^2\\\\V=6x^3+3x^2\)
So, the volume of the figure is equal to \(6x^3+3x^2\).

one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

The area of the parallelogram is 60 square millimeters.
What is the parallelogram's base, b?
The base of the parallelogram is 60.
How to find?
To find the base of a parallelogram, we need to know its area and height. The area of a parallelogram is given by the formula:
A = b × h
where A is the area, b is the base, and h is the height.
In this case, we are given that the area of the parallelogram is 60 square millimeters. We do not know the height of the parallelogram, so we cannot solve for the base directly.
However, we do know that the area of a parallelogram is equal to the product of its base and height. So, if we can find the height of the parallelogram, we can then use the formula to solve for the base.
To find the height, we can use the formula:
h = A / b
where A is the area and b is the base.
Substituting the given values, we get:
h = 60 / b
Now, we still do not know the value of the base, but we can use this expression for the height to set up an equation that relates the base and height of the parallelogram.
We know that the opposite sides of a parallelogram are parallel and have the same length, so the height of the parallelogram is perpendicular to the base. Therefore, we can draw a perpendicular line from the height to the base, dividing the parallelogram into two congruent triangles.
Each triangle has an area of A/2, and its base and height are b and h, respectively. Therefore, we can set up the following equation:
A/2 = bh/2
Substituting the expression for the height, we get:
A/2 = b(60/b)/2
Simplifying, we get:
A/2 = 30
Multiplying both sides by 2, we get:
A = 60 = bh
Now we have an equation that relates the base and area of the parallelogram. Substituting the given value for the area, we get:
60 = b × h
Substituting the expression for the height, we get:
60 = b × (60 / b)
Simplifying, we get:
60 = 60
This equation is always true, which means that any value of b that satisfies the condition for a parallelogram (i.e., opposite sides are parallel and have the same length) will work. Therefore, we cannot determine the value of the base without additional information.

Like us, mice are warm-blooded creatures. Their bodies must maintain a constant
temperature of 37°C, regardless of the temperature of their environment. Doing so burns
calories. The more severe the temperature difference, the more calories the mouse must
burn to maintain its body temperature. Consulting the research literature, you found the
following model:
C = 0.37219T + 1,560
Where C is the number of calories an idle mouse burns each day and T is the temperature
of its environment in °C. What is the most comfortable temperature for an idle mouse?
(This is the temperature where it burns the least calories per day). How many calories will
it burn each day at that temperature?
At a temperature of 20°C, the mouse would burn approximately 1,567.44 calories each day.
According to the given model C = 0.37219T + 1,560, where C represents the number of calories an idle mouse burns each day and T represents the temperature of its environment in °C.
To find the most comfortable temperature for an idle mouse, we need to determine the temperature at which the mouse burns the least amount of calories per day.
To find this temperature, we can minimize the equation C = 0.37219T + 1,560. To do so, we take the derivative of C with respect to T and set it equal to zero:
dC/dT = 0.37219 = 0
Solving this equation, we find that the derivative is a constant value, indicating that the function C = 0.37219T + 1,560 is a linear equation with a slope of 0.37219. This means that the mouse burns the least calories at any temperature, as the slope is positive.
Therefore, there is no specific "most comfortable" temperature for an idle mouse in terms of minimizing calorie burn. However, if we consider the range of temperatures mice typically encounter, we can find a temperature where the calorie burn is relatively low.
For example, if we take a temperature of 20°C, we can calculate the calorie burn:
C = 0.37219 * 20 + 1,560
C = 7.4438 + 1,560
C ≈ 1,567.4438 calories per day
Therefore, at a temperature of 20°C, the mouse would burn approximately 1,567.44 calories each day.
