Answer:

           y - 12 = 5(x - 3)    {the point-slope form of the equation}

            y = 5x + 9            {the slope-intercept form of the equation}

           5x - y = -9            {standard form of the equation}

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

y = 5x - 7     ⇒   m = 5

(3, 12)    ⇒   x₀ = 3,  y₀ = 12

So, the point-slope form of the equation:

y - 12 = 5(x - 3)

Therefore:

y - 12 = 5x - 3         {add 12 to both sides}

y = 5x + 9             ←  the slope-intercept form of the equation

y = 5x + 9               {subtract5x from both sides}

y - 5x = 9               {multiply both sides by (-1)}

5x - y = -9             ← the standard form of the equation

When the patient recovery time from a specific surgical procedure is normally distributed, with a mean of 5.2 days and a standard deviation of 2.3 days, the probability of spending more than 2 days in recovery will be 0.61.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. Information about the likelihood that something will happen is provided by probability. For instance, meteorologists use weather patterns to forecast the likelihood of rain. Probability theory is used in epidemiology to comprehend the connection between exposures and the risk of health effects.

Here,

z=(X-μ)/σ

X=2

μ=5.2

σ=2.3

Z=(2-5.2)/2.3

Z=-1.39

-1.39+1

=0.39

1-0.39=0.61

The probability of spending more than 2 days in recovery will be 0.61 when the patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 2.3 days.

The ethnicity of respondents in a political poll of randomly selected adults is an example of a categorical variable.

A categorical variable is a type of variable that represents data that can be categorized into distinct groups or categories. In this case, the ethnicity of the individual respondents in the political poll represents different categories such as Asian, African American, Hispanic, Caucasian, etc. Each respondent falls into one of these categories based on their ethnicity.

The variable is categorical because it does not have numerical values that can be quantified or measured. Instead, it represents qualitative data that can be described using labels or categories.

Therefore, the ethnicity of the individual respondents in a political poll of randomly selected adults is an example of a categorical variable.

Dilations involve scaling the figure uniformly along a given center and factor. This process results in an enlarged or reduced version of the original figure, while maintaining the same proportions and shape.

A dilation is a type of geometric transformation that alters the size or shape of a figure while preserving its proportions. It involves scaling the figure uniformly in all directions from a specific center of dilation. The scaling factor determines whether the figure will be enlarged or reduced.

When dilating a figure, each point is moved along a line that passes through the center of dilation. The distance between the original point and the center is multiplied by the scaling factor to determine the new position of the point. If the scaling factor is greater than 1, the figure will be enlarged, while a scaling factor between 0 and 1 will result in a reduction.

The center of dilation can be any point on the plane, and it serves as the reference point from which the scaling occurs. If the center of dilation is outside the figure, the shape will change along with the size. However, if the center is inside the figure, only the size will be affected, and the shape will remain the same.

The correct option is B) Not valid. Consider the statement “Since some shoes are sneakers, some non-sneakers are non-shoes.”

We know that all sneakers are shoes, but all shoes are not sneakers.  Hence, some shoes are sneakers. But, this statement does not imply that “some non-sneakers are non-shoes.” This inference cannot be drawn by contraposition. So, it is not valid.Inferences cannot be drawn in contraposition all the time. Contraposition is a type of logical statement that involves reversing and negating the terms of an original proposition. It is a logical relationship between a proposition and its converse. If a proposition is true, the contrapositive is always true.An example of contraposition can be shown as follows:“If a person is a human, then they are mortal.”We can write the contrapositive of this statement as:“If a person is not mortal, then they are not human.”

The approximate year at which two revenues were equal is; 7.5 years

From the graph attached, we see that in the year 10, the revenue for printed ads was 2 million dollars & 3 million dollars for printed ads and online ads revenue respectively.

Thus, printed ad. Revenue line equation is;

(y - 2) = (3 - 2)(x - 10)/(0 - 10)

y - 2 = (x - 10)/-10

x - 10 = -10(y - 2)

x - 10 = -10y + 20

x - 10 = -10y + 20

x  + 10y = 30   -----(1)

At x = 12 years from the graph, we have;

12 + 10y = 30

10y = 18

y = 1.8

Thus, online ad. Revenue line equation is;

(y - 0) = ((3 - 0)/(10 - 0))(x - 0)

y = 3x/10

10y = 3x

10y - 3x = 0 -----(2)

At x = 12, we have;

10y = 3*12

10y = 36

y = 3.6

In year '12' the online ad revenue got doubled as that of printed ad revenue and afterward more than doubled.

(a) The probability of reaching state 2 in 5 transitions starting from state 3 is 2/7776.,  (b) The expected numbers of visits to all states after 6 transitions starting from state 3 can be calculated using path probabilities.



(a) The probability that the Markov chain enters state 2 in 5 transitions starting from state 3 can be calculated by considering all the possible paths. In this case, there are two possible paths to reach state 2 in 5 transitions: 3 → 4 → 5 → 6 → 1 → 2 and 3 → 2 → 1 → 6 → 5 → 4 → 3.

Since each transition has an equal probability of occurring, the probability of each path is (1/6)^5 = 1/7776. Since there are two paths, the total probability of reaching state 2 in 5 transitions starting from state 3 is 2/7776.

(b) To calculate the expected number of visits from state 3 to all states (including 3 itself) after 6 transitions, we need to consider the possible paths and their probabilities. Starting from state 3, there are several possible paths to reach each state in 6 transitions. We can calculate the expected number of visits by summing up the probabilities of each path multiplied by the number of visits to the desired state in that path.

For example, to calculate the expected number of visits to state 2 in 6 transitions starting from state 3, we need to consider all possible paths that lead to state 2. These paths are: 3 → 4 → 5 → 6 → 1 → 2, 3 → 2 → 1 → 6 → 5 → 4 → 3 → 2, and 3 → 4 → 3 → 2. Each path has a certain probability associated with it, and we can calculate the expected number of visits to state 2 by multiplying the probability of each path by the number of visits to state 2 in that path.Similarly, we can calculate the expected number of visits to all other states by considering their respective paths. The expected number of visits to a state can be seen as the average number of times the Markov chain visits that state over a large number of trials.

Therefore, (a) The probability of reaching state 2 in 5 transitions starting from state 3 is 2/7776.,  (b) The expected numbers of visits to all states after 6 transitions starting from state 3 can be calculated using path probabilities.

Answer:

68%

Step-by-step explanation:

Given that :

Game 1 = 30 times in 90 times at bat

Game 2 = 40 times in 120 times at bat

Game 3 = 42 times in 140 times at bat

Total strike outs = (30 + 40 + 42) = 112

Total time at bat = (90 + 120 + 140) = 350

Total hits = total time at bats - total strike outs

Total hits = 350 - 112 = 238

Percentage hits :

(Total hits / total time at bats) * 100%

(238 / 350) * 100%

0.68 * 100%

= 68%

Emerson actually hit the ball 32% of times at bat.

Since in Game 1, Emerson struck out 30 times in 90 times at bat; in Game 2, he struck out 40 times in 120 times at bat; and in Game 3, Emerson struck out 42 times in 140 times at bat; To determine what percentage of times at bat did Emerson actually hit the ball, the following calculation must be performed:
