Step-by-step explanation:

The probability of the message being "hi" given the ciphertext "st" is 0.

Consider a shift cipher with three possible messages, with a distribution of probabilities. The three possible messages are as follows:

Pr[M=‘hi’] = 0.3,

Pr[M=‘no’] = 0.2, and

Pr[M=’in’] = 0.5.

To solve this problem, we can use Bayes' theorem. We want to find the probability of the message being "hi" given the ciphertext "st".

Using Bayes' theorem, we have:

Pr[M=‘hi’ | C=‘st’] = Pr[C=‘st’ | M=‘hi’] * Pr[M=‘hi’] / Pr[C=‘st’]

We can break this down into three parts:

Pr[C=‘st’ | M=‘hi’]:

This is the probability that the ciphertext is "st" given that the message is "hi".

To find this probability, we need to encrypt the message "hi" using the shift cipher. If we shift each letter in "hi" by one (i.e., a becomes b, h becomes i, and i becomes j), we get the ciphertext "ij". Since "ij" does not contain the letter "s", we know that Pr[C=‘st’ | M=‘hi’] = 0.Pr[M=‘hi’]:

This is the probability of the message "hi", which is given as 0.3.Pr[C=‘st’]:

This is the probability of the ciphertext "st". We can find this probability by considering all the possible messages that could have been encrypted to produce "st".

There are three possible messages: "hi", "no", and "in". To encrypt "hi" to "st", we need to shift each letter in "hi" by two (i.e., a becomes c, h becomes j, and i becomes k). This gives us the ciphertext "jk".

To encrypt "no" to "st", we need to shift each letter in "no" by five (i.e., n becomes s and o becomes t). This gives us the ciphertext "st". To encrypt "in" to "st", we need to shift each letter in "in" by three (i.e., i becomes l and n becomes q). This does not give us the ciphertext "st", so we can ignore it.

Therefore, Pr[C=‘st’] = Pr[C=‘st’ | M=‘hi’] * Pr[M=‘hi’] + Pr[C=‘st’ | M=‘no’] * Pr[M=‘no’] = 0 + 0.2 * 1 = 0.2

Now we can plug in the values we have found:

Pr[M=‘hi’ | C=‘st’] = 0 * 0.3 / 0.2 = 0

Answer: F. (25 − c) ÷ 4

Step-by-step explanation:

Emma had 25 cookies and gave c cookies to her mom and then divided the rest evenly amongst her 4 friends.

The cookies she shared to her friends are the 25 cookies minus the number of cookies she gave her mom which is:

= 25 - c

This (25 - c) was divided by 4 with each portion given to a friend so the total each friend got was:

= (25 - c) / 4

The given statement "Compared to a z-score, a hypothesis test with a t statistic requires more information from the sample." is True because hypothesis test need more information than z-score.

A z-score is used when the population standard deviation is known, and the sample size is large. In contrast, a t-statistic is used when the population standard deviation is unknown, and the sample size is small.

When conducting a hypothesis test with a t-statistic, more information from the sample is required to estimate the population standard deviation. This is because the sample standard deviation is used to estimate the population standard deviation, and it is not always an accurate estimate, especially when the sample size is small.

In addition, the use of a t-distribution introduces more uncertainty into the test, as the distribution is wider and flatter than the normal distribution used for z-scores.

Therefore, when conducting a hypothesis test with a t-statistic, more information from the sample is required to account for the increased uncertainty introduced by the smaller sample size and the estimation of the population standard deviation.

The image of the point (6, 13) under a dilation centered at (0, 0) with a scale factor of √6 is (6√6, 13√6).

We have,

To find the image of the point (6, 13) under a dilation centered at (0, 0) with a scale factor of √6, we can use the following formula:

(x', y') = (kx, ky)

where (x', y') are the coordinates of the image point, (x, y) are the coordinates of the original point, and k is the scale factor.

Now,

k = √6

x = 6

y = 13

So, the image point (x', y').

x' = kx = √6 × 6 = 6√6

y' = ky = √6 × 13 = 13√6

Igraine is incorrect in stating that a rectangular prism is the best model for approximating the surface area of a fire extinguisher. The fire extinguisher has a curved surface, which cannot be properly approximated by a rectangular prism.

The curved surface of the fire extinguisher indicates that a cylindrical model would be more appropriate for approximating its surface area.

A cylindrical model would consist of a curved lateral surface area and two circular bases. While a rectangular prism could be used to approximate the volume of the fire extinguisher, it would not be the best model for approximating the surface area.

The equation of the graphed function is given as follows:

f(x) = x³ + 2x² - 5x - 6.

The equation of the function is obtained considering the Factor Theorem, as a product of the linear factors of the function.

From the graph, the zeros of the function are:

Hence the function is:

f(x) = a(x + 3)(x + 1)(x - 2).

In which a is the leading coefficient.

Expanding the product, we have that:

f(x) = a(x² + 4x + 3)(x - 2)

f(x) = a(x³ + 2x² - 5x - 6).

When x = 0, y = -6, hence the leading coefficient a is obtained as follows:

-6a = -6

a = 1.

Hence the function is:

f(x) = x³ + 2x² - 5x - 6.

The probability that an archer hits the bullseye at most three out of five times is 0.8914.

We need to find the probability that the archer hits the bullseye at most three out of five times.

Now we know that the probability of hitting the bullseye is 25%.

Thus, the probability of not hitting the bullseye is 1-0.25 = 0.75

Now the probability of hitting the bullseye at least three out of five times can be obtained by adding the probabilities of hitting the bullseye three, four, or five times.

So, the probability of hitting the bullseye three times is 5C3 (0.25)^3 (0.75)^2 = 0.2637

The probability of hitting the bullseye four times is 5C4 (0.25)^4 (0.75)^1 = 0.0879

The probability of hitting the bullseye five times is 5C5 (0.25)^5 (0.75)^0 = 0.00098

Therefore, the probability of hitting the bullseye at most three out of five times is:

P(at most three out of five times) = P(hitting three times) + P(hitting four times) + P(hitting five times)P(at most three out of five times)

= 0.2637 + 0.0879 + 0.00098P(at most three out of five times) = 0.35258

The required probability is 0.35258, which when rounded to four decimal places, is 0.8914.

Answer:

The sequence is:

5, 14, 23, 32

Step-by-step explanation:

We know that an Arithmetic sequence with a₁ and the commo difference 'd' has the nth term such as:

aₙ = a₁ + (n-1)d

Given the arithmetic sequence

5, _____, ______, 32

here:

a₁ = 5

n = 4

aₙ

so substituting a₁ = 5, n = 4 and aₙ = 32 in the nth term

aₙ = a₁ + (n-1)d

32 = 5 + (4-1)d

32 = 5 + 3d

3d = 32-5

3d = 27

divide both sides by 3

3d/3 = 27/3

d = 9

Therefore, the common difference: d = 9

Determining the 2nd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 2, a₁ = 5, d = 9

a₂ = 5 + (2-1)9

a₂ = 5 + 1(9)

a₂ = 5 + 9

a₂ = 14

Determining the 3rd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 3, a₁ = 5, d = 9

a₃ = 5 + (3-1)9

a₃ = 5 + 2(9)

a₃ = 5 + 18

a₃ = 23

Thus, the sequence becomes:

For numbers less than 0.1, such as 0.06, the zeros to the right of the decimal point but before the first nonzero digit are called leading zeros.

When we have a decimal number less than 0.1, there may be one or more zeros between the decimal point and the first nonzero digit. These zeros are known as leading zeros. In the example of 0.06, the zero before the 6 is a leading zero. It indicates that the number is less than 0.1 but greater than 0.01. The leading zero helps establish the position of the decimal point and provides clarity about the magnitude of the number.

Leading zeros are significant in decimal notation because they affect the place value of the digits. Each leading zero shifts the decimal point one place to the right, indicating a smaller value.

It's important to recognize and include leading zeros when working with decimal numbers to maintain accuracy and precision. They contribute to the overall value and understanding of the number's magnitude, especially when comparing and performing calculations involving decimal quantities.
