In the limit, the deck of cards will be perfectly shuffled, in the sense that any of the n! possible orderings are equally likely.

The question is asking to show that, in the limit, a deck of n cards will be perfectly shuffled if each number from 1 to n is randomly chosen and the chosen card is placed in position 1. This can be shown as follows:

Let us denote the initial ordering of the deck of cards by P1, P2, ..., Pn. Suppose the first card chosen is Pi, and thus it is put in position 1. Now the ordering is Pi, P1, ..., Pn.

Suppose the next card chosen is Pj. Thus the ordering is now Pj, Pi, P1, ..., Pn. By repeating this process, the ordering of the deck is changing.

As each of the numbers 1, 2, ..., n is equally likely to be chosen, the probability of any particular ordering is the same. This means that, in the limit, the deck of cards will be perfectly shuffled, in the sense that any of the n! possible orderings are equally likely.

Answer:

\(2*2^1^/^4\)

(≈2.378)

Step-by-step explanation:

we know that:

\(a^x*a^y=a^x^+^y\)

[this is the same as multiplying any exponents]

3/4 + 1/2 = 1 + 1/4

if [\(a^x*a^y=a^x^+^y\)], then [\(a^x^+^y=a^x*a^y\)] must also be true

so,

\(2^1^+^1^/^4=2^1*2^1^/^4\\\)

= \(2*2^1^/^4\)

(\(2^1^/^4 = 1.189207115\))

1.189207115 · 2 = 2.37841423001

(rounded to 2.378)

Answer:

\(2*2^1^/^4\)

(2.37841)

Explanation:

3/4 + 1/2 = 1 + 1/4

= \(2*2^1^/^4\)

(\(2^1^/^4 = 1.189207115\))

(2)(1.189207115) = 2.37841423001

So, Lana gave away 26.32% of he Pokemon cards  to her little brother.

To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.

In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:

(125 / 475) * 100 = 0.2632 * 100 = 26.32%.

Lana gave away 26.32% of her Pokemon cards to her little brother.

Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:

Percentage given away

= (Cards given away / Total cards) * 100

= (125 / 475) * 100

= 26.32%.

x is greater than eleven thirds.

Inequality are expression that have <, > , ≤ and ≥ .

Therefore,

1 / 5 (5x) + 10 + 5x > 32

Hence,

1 / 5 × 5x + 10 + 5x > 32

x + 10 + 5x >32

combine like terms

x + 10 + 5x >32

x + 5x + 10 > 32

Therefore,

x + 5x + 10 > 32

6x + 10 > 32

subtract 10 from both sides

6x + 10 - 10 > 32 - 10

6x > 22

The probability that 0 customers arrive during a 10-minute period is given as follows:

0.0183 = 1.83%.

We are given the mean during a time interval, hence the Poisson distribution is used to obtain the probability in this problem.

The mass probability function for the Poisson distribution is given as follows:

\(P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}\)

The parameters are given as follows:

The standard deviation for the Poisson distribution is the square root of the mean, hence the mean is calculated as follows:

\(\mu = 2^2 = 4\)

Then the probability that 0 customers arrive during a 10-minute period is calculated as follows:

P(X = 0) = e^(-4) = 0.0183 = 1.83%.

We would expect to see around 200 fewer accidents per year among 16-year-old drivers in your state if the proposal to increase the permit period from 6 to 12 months is implemented.

Estimation is the process of determining an estimate or approximation, which is a value that can be used for a specific purpose even when the input data is incomplete, uncertain, or unstable.

It is difficult to predict exactly how many fewer accidents would occur as a result of increasing the time a driver must hold a learner's permit from 6 to 12 months. However, there is evidence to suggest that longer permit periods can result in fewer accidents, as novice drivers have more time to gain experience under supervision before obtaining a full license.

According to research by the Insurance Institute for Highway Safety, increasing the permit period from 6 to 12 months could lead to a 20% reduction in crash rates among 16-year-old drivers.

Assuming this reduction holds true in your state, we can estimate the number of accidents that would be prevented by multiplying the current number of accidents involving 16-year-old drivers (let's assume 1,000 per year) by 20%, or 0.2. This gives us an estimated reduction of 200 accidents per year.

Answer:

approximately 12.67 feet (not sure about this)

Step-by-step explanation:

We know that Monica's scale drawing of her room is 7.4 inches long and 5 inches wide. Let's call the width of her actual bedroom "w".

To find the width of the actual room, we need to set up a proportion using the scale factor:

scale factor = length on drawing / actual length

Since we know the length on the drawing is 7.4 inches and the actual length is 18.75 feet, we can set up the following proportion:

7.4 inches / 18.75 feet = 5 inches / w

To solve for w, we can cross-multiply:

7.4 inches * w = 18.75 feet * 5 inches

Simplifying:

7.4w = 93.75

Dividing both sides by 7.4:

w = 12.67 feet

Therefore, the width of Monica's actual bedroom is approximately 12.67 feet.

Step-by-step explanation:

One way to simplify variables with many levels (or decimal places) when creating a frequency distribution is to organize the data into class intervals (option B).

By grouping the data into intervals, the frequency distribution becomes more manageable and easier to interpret. This process involves dividing the range of values into distinct intervals or categories and then counting the number of observations falling within each interval. Class intervals provide a summary of the data by grouping similar values together, reducing the complexity of individual levels or decimal places.

This simplification technique is particularly useful when dealing with large datasets or continuous variables that have numerous levels or decimal values, allowing for a clearer representation and analysis of the data.

Option B holds true.

After calculating the distance, Ranjan has driven 358.55 miles so far.

To solve this problem, we need to use the formula:

distance = fuel efficiency x fuel consumed

Let's start by calculating the total fuel consumed. At the first stop, Ranjan adds 6.7 gallons of gas, which means he consumed 6.7 gallons of gas since his tank was full at the beginning of the trip. At the second stop, he adds 3.4 gallons of gas, which means he consumed 3.4 gallons of gas between the first and second stops. Therefore, the total fuel consumed is:

6.7 + 3.4 = 10.1 gallons

Now we can calculate the distance driven using the fuel efficiency of 35.5 miles per gallon:

distance = 35.5 miles/gallon x 10.1 gallons = 358.55 miles

Therefore, Ranjan has driven 358.55 miles so far.
