Here, we have
Given the animal total in the park number marked
We have to find the probability of the next elk caught in the park being unmarked.
There are a total of 5625 elks in the park. 225 of those are marked.
5625 - 225 = 5400
So, 5400 elks are not marked yet.
5400/5626 = 0.96 = 96%
Hence, 0.96 is the probability of the next elk caught in the park being unmarked.

Assume that each year the IRS randomly audits 30% of the tax returns. If a married couple has filed separate returns, answer the following questions. (a) What is the probability that both the husband and the wife will be audited? (b) What is the probability that only one of them will be audited? (c) What is the probability that neither one of them will be audited? (d) What is the probability that at least one of them will be audited?
the probability of both the husband and wife being audited is relatively low at 0.09, while the probability of at least one of them being audited is higher at 0.51
(a) The probability that both the husband and the wife will be audited can be calculated as the product of the individual probabilities that each of them is audited, since the audits are assumed to be independent events. Therefore, the probability that both of them will be audited is:
P(both audited) = P(husband audited) * P(wife audited) = 0.3 * 0.3 = 0.09
(b) The probability that only one of them will be audited can be calculated by considering the two cases: either the husband is audited and the wife is not, or the wife is audited and the husband is not. Since these are mutually exclusive events, we can add their probabilities to get the total probability. Therefore, the probability that only one of them will be audited is:
P(only one audited) = P(husband audited) * P(wife not audited) + P(husband not audited) * P(wife audited) = 0.3 * 0.7 + 0.7 * 0.3 = 0.42
(c) The probability that neither one of them will be audited is the complement of the probability that at least one of them will be audited. Therefore, we can subtract the probability of at least one audit from 1 to get:
P(neither audited) = 1 - P(at least one audited)
(d) To calculate the probability that at least one of them will be audited, we can use the complement rule and subtract the probability that neither of them will be audited from 1. Therefore:
P(at least one audited) = 1 - P(neither audited)
= 1 - (0.7 * 0.7)
= 1 - 0.49
= 0.51
In conclusion, the probability of both the husband and wife being audited is relatively low at 0.09, while the probability of at least one of them being audited is higher at 0.51. However, it is important to note that these are only probabilities and the actual outcome may differ from these estimates. Therefore, taxpayers should always be honest and accurate in their tax returns to avoid the potential consequences of an audit.

The population of Columbus in 2015 was 840,000 people. In 2018 (three years later), The population grew to 972,405 people. Write an exponential equations that models this situation.
Answer:
N = I ( 1 + 50% )^t
Step-by-step explanation:
Given that The population of Columbus in 2015 was 840,000 people. In 2018 (three years later), The population grew to 972,405 people.
Write an exponential equations that models this situation.
From the question, the following parameters are given :
Initial number of population = 840,000
The new number of population = 972,405
The number of years = 3
Let the initial population = I
The new population = N
And the number of years = t
Since the population is increasing, the exponential equation can be written as
N = I ( 1 + R% )^t
Where R% is the percentage increase.
Solve for R
972405 = 840,000 ( 1 + R% )^3
972405/840000 = ( 1 + R% )^3
1.157625 = ( 1 + R% )^3
( 1 + R% ) = 1.05
Make R% the subject of formula
R% = 1.05 - 1
R% = 0.5
R = 0.5 × 100
R = 50%
Therefore, the exponential equations that models this situation can be expressed as:
N = I ( 1 + 50% )^t

a)State 1 is absorbing b) States 4 and 5 are periodic c) State 1 is transient d) State 1 is recurrent e) States 3, 4 and 5 are recurrent f) Only state 3 is recurrent
In the given Markov chain, State 1 is absorbing, State 4 is periodic, State 1 is recurrent, and States 3, 4, and 5 are recurrent.
A Markov chain is a stochastic model that represents a sequence of states where the probability of transitioning from one state to another depends only on the current state. Let's analyze the given Markov chain to determine the properties of each state.
State 1: This state has a probability of 1 in the first row, indicating that it is an absorbing state. An absorbing state is one from which there is no possibility of leaving once it is reached. Therefore, statement a) is correct, and State 1 is absorbing.
State 2: There are no transitions from State 2 to any other state, which means it is an absorbing state as well. However, since it is not explicitly mentioned in the question, we cannot determine its status based on the given information.
State 3: This state has non-zero probabilities to transition to other states, indicating that it is not absorbing. Furthermore, it has a loop back to itself with a probability of 1/6, making it recurrent. Hence, statements c) and e) are incorrect, while statement f) is correct. State 3 is recurrent.
State 4: State 4 has a transition probability of 1/3 to State 3, which means there is a possibility of leaving this state. However, there are no outgoing transitions from State 4, making it an absorbing state. Moreover, since there is a loop back to itself with a probability of 2/3, it is also recurrent. Therefore, statement b) is correct, and State 4 is periodic and recurrent.
State 5: Similar to State 4, State 5 has a transition probability of 2/3 to State 3 and no outgoing transitions. Hence, State 5 is also an absorbing and recurrent state. Consequently, statement e) is correct.
To summarize, State 1 is absorbing and recurrent, State 4 is periodic and recurrent, and States 3 and 5 are recurrent.

Can someone please help me with this question?
A semicircle has radius 5.6cm. Work out the perimeter of the semicircle.
Answer:
28.79 cm.
Step-by-step explanation:
The perimeter of a semicircle is equal to the sum of the diameter (which is twice the radius) and half of the circumference of the circle.
The diameter of the semicircle is 2 × 5.6cm = 11.2cm.
The circumference of a full circle with radius 5.6cm is 2π × 5.6cm = 11.2π cm.
Therefore, the circumference of the semicircle is 1/2 of the circumference of the full circle, which is 1/2 × 11.2π cm = 5.6π cm.
The perimeter of the semicircle is the sum of the diameter and the circumference, which is:
11.2cm + 5.6π cm ≈ 28.79cm (rounded to two decimal places)
Therefore, the perimeter of the semicircle is approximately 28.79 cm.
Answer:
pi ( 5.6 ) + 11.2 or approximately 28.79291 cm
Step-by-step explanation:
The outside of the semicircle or the perimeter is 1/2 of the circumference and the length that closes the circle is the diameter.
Perimeter = 1/2 C + d
= 1/2 *pi*d + d
The diameter is 2 times the radius.
= 1/2 ( pi) * (2r) + 2r
= pi r + 2 r
= pi ( 5.6 ) + 11.2
Approximating pi, we get approximately 28.79291

The mass of a spherical grape is 8.4 grams and its density is 2 grams per cubic centimeter. What is the radius of the grape? Round to the nearest tenth of a centimeter. 1.0 cm 1.5 cm 1.9 cm 2.1 cm
Answer: 1.0cm
Step-by-step explanation:
Given the following :
Volume = Mass / Density
Given that:
Mass of spherical grape = 8.4g
Density = 2g/cm^3
Radius of the grape =?
Volume of grape = mass of grape / density of grape
Volume = 8.4g / 2g/cm^3
Volume = 4.2cm^3
Volume of a sphere = (4/3)πr^3
4.2 = 4/3 * 3.14 * r^3
4.2 = (12 * r^3) / 3

What were Malcolm's and Ravi's maximum speeds?
Answer:
Malcom's maximum speed = 200 km/h
Ravi's maximum speed = 320 km/h
Step-by-step explanation:
Let m = Malcom's maximum speed
Let r = Ravi's maximum speed
Average of their maximum speed would be represented as \( \frac{m + r}{2} = 260 \)
\( m + r = 520 \).
Make m the subject of the formula by subtracting r from both sides:
\( m = 520 - r \). Let this be equation 1.
Given that Malcom's speed (m), when doubled is 80 km/h more than that of Ravi (r). This can be expressed as: \( 2m = r + 80 \). This is equation 2.
Plug in (520 - r) into equation 2 to replace m:
\( 2(520 - r) = r + 80 \)
\( 1040 - 2r = r + 80 \)
Solve for r. Subtract 1040 from both sides:
\( 1040 - 2r - 1040 = r + 80 - 1040 \)
\( - 2r = r - 960 \)
Subtract r from both sides
\( - 2r - r = r - 960 - r \)
\( - 3r = - 960 \)
Divide both sides by -3
\( \frac{-3r}{-3} = \frac{-960}{-3} \)
\( r = 320 \)
To find m, plug in the value of r into equation 1.
\( m = 520 - r \). =>Equation 1
\( m = 520 - 320 \)
\( m = 200 \).
Malcom's maximum speed = m = 200 km/h
Ravi's maximum speed = r = 320 km/h

Let's perform the required calculations:
(a) ||A||:
To find the norm of matrix A, we need to take the square root of the sum of the squares of its elements:
||A|| = √(1^2 + 1^2 + (-1)^2 + 0^2 + 1^2 + 8^2) = √(1 + 1 + 1 + 0 + 1 + 64) = √68 ≈ 8.246
(b) ||B||:
Similarly, we find the norm of matrix B:
||B|| = √((-1)^2 + 1^2 + 1^2 + 1^2) = √(1 + 1 + 1 + 1) = √4 = 2
(c) A + B:
To add matrices A and B, we simply add the corresponding elements:
A + B = [1 + (-1) 1 + 1 -1 + 1 0 + 1 8 + 1 0 + 1] = [0 2 0 9 1]
(d) ||A + B||:
To find the norm of matrix A + B, we perform a similar calculation as in (a):
||A + B|| = √(0^2 + 2^2 + 0^2 + 9^2 + 1^2) = √(0 + 4 + 0 + 81 + 1) = √86 ≈ 9.274
Therefore, the results are:
(a) ||A|| ≈ 8.246
(b) ||B|| = 2
(c) A + B = [0 2 0 9 1]
(d) ||A + B|| ≈ 9.274
