The probability that a patient who takes the drug will experience relief of at least one of the two symptoms is 0.72.

Probability is defined as the likeliness of an event to occur. The probability of any event to occur ranges from 0 to 1, and the sum of all the probabilities of all the events happening is 1.

probability = desired outcome / total outcomes

If 90 of the patient's treated experienced eye relief and 45 experienced relief of both itchy eyes and the skin rash, then 45 experienced eye relief only.

eye relief only = 90 - 45 = 45

If 135 had their skin rash clear up, and 45 experienced relief of both itchy eyes and the skin rash, then 90 had their skin rash clear up only.

skin rash clear up only =  135 - 45 = 90

Hence, the total number of patients who took the drug and experienced relief of at least one of the two symptoms is 180.

45 + 90 + 45 = 180

Divide by the total number of patients.

probability = desired outcome / total outcomes

probability = 180 / 250

probability = 0.72

a) The baseball executive's belief that the best prediction of a team's wins in 2015 should be equal to their wins in 2014 is not entirely accurate as the correlation between a team's wins one season and their wins the next season is 0.54, which means that there is a correlation between the team's wins in the two seasons but it is not perfect.

This means that a team's wins in one season cannot be the best prediction of their wins in the following season. Additionally, the distribution of the number of wins by Major League Baseball teams has an approximately normal distribution with mean 81 and standard deviation 11.7.

Therefore, a team's wins in 2015 is likely to be lower or higher than their wins in 2014 based on the team's performance and randomness.

(b) The regression equation can be represented as:

W_2015 = a + bW_2014W_2015 = 10.64 + 0.51 (98)W_2015 = 60.02

Therefore, using regression, the Los Angeles Angels are predicted to win 60 games in 2015, which is lower than their 98 wins in 2014.

(c) The executive's suspicions are misplaced because even though no team is predicted to win more than 91 games, the regression equation is based on the mean and standard deviation of the distribution of the number of wins by Major League Baseball teams, which has an approximately normal distribution with mean 81 and standard deviation 11.7.

Therefore, it is likely that there will be some teams that will win more than 91 games, but the prediction is based on the data that is available. Additionally, the prediction is based on probability and there is always a chance of an event happening that is outside the normal distribution.

According to the census data, the population of China is more than the population of US by a factor 4.2

Given data

population of China = 1.3x10^9

population of US = 308,745,538

population of china = 1.3x10^9. can be rewritten as = 1,300,000,000

comparing the both figures representing population. we divide the population of China by the population of US

let the number of times the population of china is greater than population of US be x, such that

308,745,538 * x = 1,300,000,000

308,745,538x = 1,300,000,000

x = 1,300,000,000 / 308,745,538

x = 4.2106

x ≅ 4.2

Answer:

Step-by-step explanation:

x represents the numbers of months and y represents the insect

population.

We are told that:

  1) we start with 125 insects, and

 2) the rascals double each month

Lets use m for months they double from the start of 125 insects.).

We can form an equation that will predict the insect population as a function of the numbers of months, m, from the start (125 insects).

Month 0 is 125

Month 1 would be 125*(1+1) or 125*2

 We can rewrite this as 125*2^1

Month 2                 125*2^2  [It dounbes again]

Month 3                  125^3     [It dounbes yet again]

Month 4                  125^4     [And again]

Month 5                  125^5     [And so on to Infinity and Beyond]

The pattern is 125*(2)^m. where m is months since the starting month of 0.

Insect Population(m) = 125*(2)^m

Answer:

John waited for Brain at the finish line for a half-hour. (or 30 minutes)

Step-by-step explanation:

The rule of the distance is D = s × t, where

Let us use this rule to solve the question

∵ John's speed = 10 miles/hour

∵ Brian's speed = 8 miles/hour

→ Slower speed takes more time

∵ The distance of the trip is 20 miles

∴ D = 20 miles

→ Find the time of each one, using the rule above

∵ D = s × t

→ Find John's time

∴ 20 = 10 × t

∴ 20 = 10t

→ Divide both sides by 10

∴ 2 = t

∴ John's time = 2 hours

→ Find Brian's time

∴ 20 = 8 × t

∴ 20 = 8t

→ Divide both sides by 8

∴ 2.5 = t

∴ Brain's time = 2.5 hours

→ Subtract their times to find for how long John waited

∵ 2.5 h - 2 h = 0.5 h

∴ The difference between their times is 0.5 hour

∴ John waited for Brain at the finish line for a half-hour (or 30 minutes)

The false statement about pie charts is: (a) Pie charts are graphical representations of the cumulative relative frequency distribution.

Pie charts are not typically used to represent the cumulative relative frequency distribution. They are commonly used to display the relative sizes or proportions of different categories within a categorical variable.

Each slice of a pie chart represents the proportion or percentage of a specific category in relation to the whole. Pie charts always have the shape of a circle, and the area of each slice corresponds to the proportion of the corresponding category in the data.

However, they are not directly used to depict cumulative relative frequency distributions, which are more commonly shown through other types of graphs such as cumulative frequency plots or histograms.

Therefore, (a) Pie charts are graphical representations of the cumulative relative frequency distribution is the correct answer.

The probability that the random sample of 16 people in the elevator will exceed the weight limit is essentially 1. Rounded to 4 decimal places, the answer is 1.0000.

To answer this question, we need to use the central limit theorem, which states that for a large enough sample size, the sample mean will be approximately normally distributed regardless of the underlying population distribution.

In this case, we are given that the weight of students, faculty, and staff is approximately normally distributed with a mean weight of 150 pounds and a standard deviation of 27 pounds. We are also given that the elevator has a weight limit of 2500 pounds and a 16-person limit.

To find the probability that the random sample of 16 people in the elevator will exceed the weight limit, we first need to calculate the mean and standard deviation of the sample.

The mean weight of the sample can be calculated as:

mean = population mean = 150 pounds

The standard deviation of the sample can be calculated using the formula:

standard deviation = population standard deviation / √sample size

standard deviation = 27 / √16 = 6.75 pounds

Next, we need to calculate the z-score for the weight limit:

z = (weight limit - mean) / standard deviation

z = (2500 - 150) / 6.75 = 341.48

This z-score is extremely high, which indicates that the probability of the sample weight exceeding the weight limit is very close to 1 (i.e., almost certain).

To calculate the actual probability, we can look up the z-score in a standard normal distribution table or use a calculator. Using a calculator, we can find that the probability of a z-score of 341.48 or higher is essentially 1.

Therefore, the probability that the random sample of 16 people in the elevator will exceed the weight limit is essentially 1. Rounded to 4 decimal places, the answer is 1.0000.

The sum of the reciprocals of the roots of the equation\(\[\frac{2003}{2004}x + \frac{1}{x} = 1\]\)is 1.

To solve this, let's first find the roots of the given equation.

Clear the fraction by multiplying both sides by 2004x:

2003\(x^2\) + 2004 = 2004x

Rearrange the equation to form a quadratic equation:

2003\(x^2\) - 2004x + 2004 = 0

Now, let's use Vieta's formulas, which relate the coefficients of a quadratic equation to the sum and product of its roots.

Let the roots of the equation be r1 and r2. According to Vieta's formulas, we have:

Sum of the roots: r1 + r2 = -b/a

Product of the roots: r1 × r2 = c/a

In our case, a = 2003, b = -2004, and c = 2004.

Calculate the sum of the roots:

r1 + r2 = -(-2004) / 2003 = 2004 / 2003

Find the sum of the reciprocals of the roots:

(1/r1) + (1/r2) = (r1 + r2) / (r1 × r2)

Since we already have the sum of the roots, we only need the product of the roots to complete the calculation:

r1 × r2 = 2004 / 2003

Plug the values into the equation:

(1/r1) + (1/r2) = (2004 / 2003) / (2004 / 2003) = 1

When the y-coordinate of the second point is -2, the slope between the points (-2, 7) and (-5, r) will be equal to 3.

Let's begin by calculating the slope between the given points (-2, 7) and (-5, r) using the slope formula:

slope = (change in y-coordinates) / (change in x-coordinates)

The change in y-coordinates is given by: y₂ - y₁

The change in x-coordinates is given by: x₂ - x₁

Substituting the values of the points into the formula, we have:

slope = (r - 7) / (-5 - (-2))

To find the value of "r" that makes the slope equal to 3, we can set up the equation:

3 = (r - 7) / (-5 - (-2))

Now, let's solve this equation for "r":

Multiply both sides of the equation by (-5 - (-2)) to eliminate the denominator:

3 * (-5 - (-2)) = r - 7

Simplifying the left side of the equation:

3 * (-5 - (-2)) = 3 * (-5 + 2) = 3 * (-3) = -9

Now, we have:

-9 = r - 7

To isolate "r," we can add 7 to both sides of the equation:

-9 + 7 = r - 7 + 7

Simplifying:

-2 = r

Therefore, the value of "r" that makes the slope equal to 3 between the points (-2, 7) and (-5, r) is -2.
