1. At a party there are four different types of soft drinks and from each type there are seven cans available. How many drinks have to be chosen so that we are guaranteed to have three cans chosen from the same type of soft drink? Explain your answer in details.

Answers

Answer 1

Nine cans must be chosen to guarantee that we have three cans of the same type of soft drink.

To guarantee that we have three cans chosen from the same type of soft drink, we need to consider the worst-case scenario, which is that we choose two cans from each type of soft drink (a total of eight cans) and none of them is the same type. In this case, we would need to choose at least nine cans to guarantee that we have three cans chosen from the same type of soft drink.

To see why this is the case, imagine choosing eight cans from the four different types of soft drinks. There are two possibilities:

1. We choose two cans from each type of soft drink, and none of them is the same type. In this case, we would need to choose at least one more can from any of the types of soft drinks to guarantee that we have three cans chosen from the same type.

2. We choose three cans from at least one type of soft drink. In this case, we already have three cans chosen from the same type.

Therefore, we need to choose at least nine cans to guarantee that we have three cans chosen from the same type of soft drink, regardless of which cans we choose.

A textile production facility produces curtains which are sold in home design stores in their area. Their gross sales in hundreds of dollars, S, is dependent on the number of curtains they produce, x, and can be modeled by the functionS(x)=−20+2.5x.Draw the graph of the gross sales function by plotting its S-intercept and another point.

Answers

Plot the points (0, -20) and (10, 5) on a graph, and draw a line connecting them to represent the gross sales function S(x) = -20 + 2.5x.


To draw the graph of the gross sales function S(x) = -20 + 2.5x, we need to plot two points: the S-intercept and another point.

First, let's find the S-intercept. The S-intercept is the value of S when x = 0. Substituting x = 0 into the function, we get:

S(0) = -20 + 2.5(0) = -20

So the S-intercept is -20, which means that when the production facility produces 0 curtains, they will not make any sales.

Now, let's find another point. We can choose any value of x and calculate the corresponding value of S. Let's choose x = 8 (you can choose any other value if you prefer). Substituting x = 8 into the function, we get:

S(8) = -20 + 2.5(8) = 0

So when the production facility produces 8 curtains, their gross sales will be $0. This means that the break-even point is at x = 8, where the revenue from selling the curtains covers the production costs.

To plot the graph, we can use these two points: the S-intercept (-20, 0) and the point (8, 0). The graph should look like this:

```
        |
        |
        |
        |         *
        |      *
        |   *
        |*_______
        0   8    x-axis
              S-axis
```

The x-axis represents the number of curtains produced, and the S-axis represents the gross sales in hundreds of dollars. The graph shows that the gross sales function is a linear function that increases as the number of curtains produced increases. The break-even point is at x = 8, and after that, the production facility starts making a profit.

Deon rented a truck for one day. There was a base fee of $20.95, and there was an additional charge of 74 cents for each mile driven. Deon had to pay $221.49 when he returned the truck. For how many miles did he drive the truck?

Answers

Answer:

Deon drove 270 miles.

Let x be the number of miles driven.

The total cost is 20.95 + 0.74x = 221.49

Subtracting 20.95 from both sides gives 0.74x = 200.54

Dividing both sides by 0.74 gives x = 270 miles

So the answer is 270

Answer:

271 miles

Step-by-step explanation:

The equation to find the total cost is

C = 20.95 + .74 m  where m is the number of miles

221.49 = 20.95 +.74m

Subtract 20.95 from each side

221.49 -20.95 = 20.95-20.95 +.74m

200.54 = .74m

Divide each side by .74

200.74/.74 = m

271 = m

Answers

We first calculate the z-score:

z = (0.517 - 0.61) / sqrt((0.61 * (1 - 0

To solve these probability questions, we need to use the central limit theorem, which states that if we have a large enough sample size, the sampling distribution of the sample proportion will be approximately normal, regardless of the population distribution.

For a sample of size n, the mean of the sample proportion (p) is equal to the population proportion (p), and the standard deviation of the sample proportion (σp) is equal to:

σp = sqrt((p(1-p))/n)

Using this information, we can standardize the sample proportion using z-score:

z = (p - p) / σp

Then, we can use the standard normal distribution table (such as Appendix A Statistical Tables) to find the probabilities.

a) What is the probability that the sample proportion is greater than 0.643?

We first calculate the z-score:

z = (0.643 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = 3.17

Using the standard normal distribution table, the probability of getting a z-score greater than 3.17 is approximately 0.0008.

Therefore, the probability that the sample proportion is greater than 0.643 is 0.0008.

b) What is the probability that the sample proportion is between 0.60 and 0.647?

We need to calculate the z-scores for both values:

z1 = (0.60 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -1.23

z2 = (0.647 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = 1.79

Using the standard normal distribution table, the probability of getting a z-score between -1.23 and 1.79 is approximately 0.8438.

Therefore, the probability that the sample proportion is between 0.60 and 0.647 is 0.8438.

c) What is the probability that the sample proportion is greater than 0.607?

We first calculate the z-score:

z = (0.607 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -0.73

Using the standard normal distribution table, the probability of getting a z-score greater than -0.73 is approximately 0.7665.

Therefore, the probability that the sample proportion is greater than 0.607 is 0.7665.

d) What is the probability that the sample proportion is between 0.57 and 0.597?

We need to calculate the z-scores for both values:

z1 = (0.57 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -4.13

z2 = (0.597 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -1.08

Using the standard normal distribution table, the probability of getting a z-score between -4.13 and -1.08 is approximately 0.0361.

Therefore, the probability that the sample proportion is between 0.57 and 0.597 is 0.0361.

e) What is the probability that the sample proportion is less than 0.517?

We first calculate the z-score:

z = (0.517 - 0.61) / sqrt((0.61 * (1 - 0

Step-by-step explanation:

Trials in an experiment with a polygraph include 99 results that include 22 cases of wrong results and 77 cases of correct results. use a 0.05 significance level to test the claim that such polygraph results are correct less than 80​% of the time. identify the null​ hypothesis, alternative​ hypothesis, test​ statistic, p-value, conclusion about the null​ hypothesis, and final conclusion that addresses the original claim. use the​ p-value method. use the normal distribution as an approximation of the binomial distribution.

Answers

Using a 0.05 significance level, a hypothesis test was conducted to determine if polygraph results are correct less than 80% of the time. So null hypothesis is not rejected by test results due to insufficiency of evidence to support the claim.

Null hypothesis, The polygraph results are correct 80% of the time or more.

Alternative hypothesis, The results given by polygraph are correct as they are less than 80% of the time.

Since the sample size is large and the success-failure condition is satisfied, we can use the normal distribution as an approximation of the binomial distribution. we can calculate the test statistic from formula

z = (p - P) / √(P(1-P)/n)

where p is the sample proportion of correct results, P is the hypothesized proportion of correct results (0.80), and n is the sample size.

p = 77/99 = 0.7778

z = (0.7778 - 0.80) / √(0.80(1-0.80)/99) = -0.6318

Using a standard normal distribution table, the p-value is found to be 0.2646.

Since the p-value (0.2646) is greater than the significance level (0.05), we fail to reject the null hypothesis. There is not enough evidence to conclude that the polygraph results are correct less than 80% of the time.

Therefore, we can conclude that at a 0.05 significance level, there is not enough evidence to support the claim that such polygraph results are correct less than 80% of the time.

1. The volume of the box is given by:

Volume = length x width x height = 9 in. x 2 in. x 12 in. = 216 cubic inches

So, the answer is 216 cubic inches.

2. The surface area of the box is given by:

Surface Area = 2lw + 2lh + 2wh = 2(9)(12) + 2(9)(2) + 2(2)(12) = 216 + 36 + 48 = 300 square inches

So, the answer is 300 square inches.

3. The surface area of the cereal box is 300 sq. in.

If cardboard costs $0.01 per square inch, then the cost of manufacturing this cereal box would be:

300 sq. in. x $0.01/sq. in. = $3.00

Therefore, the correct answer is -3.00.

4. The volume of the rectangular prism is given by:

Volume = length x width x height = 9 in. x 2 in. x 12 in. = 216 cubic inches

To find the surface area of the sphere, use the formula:

A = 4πr²

Plugging in r = 3.7 in.:

A = 4π(3.7 in.)² ≈ 172.11 square inches

Rounding this to the nearest square inch gives us:

A ≈ 172 square inches

5. The rectangular prism with dimensions of 9 in. x 2 in. x 12 in. would cost less in packaging.

6. The volume of the cylinder is given by:

Volume = πr²h = 390 cubic inches

Solving for r:

r ≈ 4 inches

Therefore, the approximate radius of the cylinder should be 4 inches to hold the same volume of cereal as the rectangular prism.

7. The surface area of the travel-size cereal box is given by:

Surface Area = 2lw + 2lh + 2wh = 2(3)(1.5) + 2(3)(4.5) + 2(1.5)(4.5) = 9 + 27 + 13.5 = 49.5 square inches

To find the length of each side in the cube with the same surface area, we use the formula:

Surface Area of Cube = 6s²

49.5 = 6s²

s ≈ 2.2 inches

So, the length of each side in the cube would be approximately 2.2 inches.

8. The rectangular prism with dimensions of 3 in. x 1.5 in. x 4.5 in. holds more volume than the cube with a side length of approximately 2.2 inches.

What is a parallelogram?

In Mathematics and Geometry, a parallelogram is a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.

In this context, we can reasonably infer and logically deduce that this parallelogram has both pairs of opposite sides parallel to each other and the opposite angles (vertical angles) are equal and congruent.

By CPCTC, the variable x can be calculated as follows;

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

suppose you are interested in investigating factors that affect the prevalence of tuberculosis among intravenous drug users. in a group of 97 individuals who admit to sharing needles, 24.7% had positive tuberculin skin test results; among 161 drug users who deny sharing needles, 17.4% had positive test results [246]. assuming that the population proportions of positive skin test results are in fact equal, estimate their common value p. test the null hypothesis that the proportions of intravenous drug users who have positive tuberculin skin test results are identical for those who share needles and those who do not. what is the probability distribution of the test statistic? what is the p-value? what do you conclude? construct a 95% confidence interval for the true difference in proportions.

Answers

a.  The probability distribution of the test statistic is approximately a standard normal distribution.

b. The p-value for the test of  factors that affect the prevalence of tuberculosis among intravenous drug users is 0.0202.  

c. We can conclude that there is a statistically significant difference between the two groups in terms of their proportions of positive skin test results.

d. The 95% confidence interval does not contain zero, so there is a statistically significant difference between the two groups in terms of their proportions of positive skin test results.

To estimate the common value of p assuming that the population proportions of positive skin test results are equal, we can compute the pooled proportion:

p-hat = (x1 + x2) / (n1 + n2)

= (24.7 + 17.4) / (97 + 161)

= 0.195

where x1 and x2 are the number of individuals with positive skin test results in the two groups, and n1 and n2 are the sample sizes.

a. To test the null hypothesis that the proportions of intravenous drug users who have positive tuberculin skin test results are identical for those who share needles and those who do not, we can use a two-sample z-test for proportions. The test statistic is:

z = (p1 - p2) / sqrt(phat * (1 - phat) * (1/n1 + 1/n2))

where p1 and p2 are the sample proportions, phat is the pooled proportion, and n1 and n2 are the sample sizes.

Plugging in the values, we get:

z = (0.247 - 0.174) / sqrt(0.195 * (1 - 0.195) * (1/97 + 1/161))

= 2.05

The probability distribution of the test statistic is approximately a standard normal distribution, since the sample sizes are large enough (both n1 and n2 are greater than 30).

b. The p-value for the test is the probability of observing a z-value of 2.05 or more extreme under the null hypothesis. From a standard normal distribution table or calculator, we find that the p-value is approximately 0.0202 (or 0.0404 for a two-tailed test).

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that the proportions of intravenous drug users who have positive tuberculin skin test results are not identical for those who share needles and those who do not.

c. To construct a 95% confidence interval for the true difference in proportions, we can use the formula:

(p1 - p2) ± z* sqrt(phat * (1 - phat) * (1/n1 + 1/n2))

where z is the critical value for a 95% confidence interval from a standard normal distribution (z = 1.96).

Plugging in the values, we get:

(0.247 - 0.174) ± 1.96 * sqrt(0.195 * (1 - 0.195) * (1/97 + 1/161))

= 0.073 ± 0.090

Therefore, we can be 95% confident that the true difference in proportions of intravenous drug users who have positive tuberculin skin test results between those who share needles and those who do not is between 0.073 and -0.073 (which can be written as an absolute value of 0.073).

d.  We can infer that there is a statistically significant difference between the two groups in terms of the proportions of positive skin test results because the interval does not contain zero.

kenny is playing on a mall escalator. he can run up the escalator in 30 seconds and it takes im 6 seconds to run up the the up escalator. how many seconds would it take kenny to run up the flight of stairs that is between the escalatos

Answers

It would take Kenny 5 seconds to run up the flight of stairs between the escalators without using the escalator.

Let's assume that the escalator has a certain height and Kenny needs to climb the same height by running up the flight of stairs between the escalators.

Let's say that the height of the escalator is h and the speed of Kenny's running is s (measured in units of height per second).

When Kenny runs up the escalator, he covers the same height h in two ways:

by running up the stairs, which takes him t seconds

by using the help of the moving escalator, which takes him 30 seconds

The speed of Kenny's running up the escalator is therefore:

s + h/30

Similarly, when Kenny runs up just the stairs, he covers the same height h in two ways:

by running up the stairs, which takes him t seconds

by running up the up escalator, which takes him 6 seconds

The speed of Kenny's running up the stairs is therefore:

s + h/6

Since the distances covered in both cases are the same, we have:

t(s + h/30) = h

t(s + h/6) = h

Dividing the second equation by the first one, we get:

(s + h/6)/(s + h/30) = 30/t

Simplifying and solving for t, we get:

t = 5 seconds

Therefore, it would take Kenny 5 seconds to run up the flight of stairs between the escalators without using the escalator.

Current Attempt in Progress In a poll, men and women were asked, "When someone yelled or snapped at you at work, how did you want to respond?" Twenty percent of the women in the survey said that they felt like crying (Time, April 4, 2011). Suppose that this result is true for the current population of women employees. A random sample of 23 women employees is selected. Use the binomial probabilities table or technology to find the probability that the number of women employees in this sample of 23 who will hold the above opinion in response to the said question is a. at least 5 Round your answer to four decimal places. P(at least 5) = i b. 7 to 9 Round your answer to four decimal places. P(at least 5) = i

Answers

the probability that 7 to 9 women in the sample will hold the opinion is 0.1790

What is frequency distribution?

The gathered data is arranged in tables based on frequency distribution. The information could consist of test results, local weather information, volleyball match results, student grades, etc. Data must be presented meaningfully for understanding after data gathering. A frequency distribution graph is a different approach to displaying data that has been represented graphically.

a. To find the probability that at least 5 women in the sample will hold the opinion, we can use the complement rule and find the probability that less than 5 women will hold the opinion, and then subtract it from 1.

P(at least 5) = 1 - P(0) - P(1) - P(2) - P(3) - P(4)

where P(k) is the probability of k women holding the opinion in the sample.

Using the binomial probabilities table or technology, we can find:

P(at least 5) = 1 - P(0) - P(1) - P(2) - P(3) - P(4)

= 1 - 0.2037 - 0.3293 - 0.2836 - 0.1565 - 0.0626

= 0.9643

So the probability that at least 5 women in the sample will hold the opinion is 0.9643 (rounded to four decimal places).

b. To find the probability that 7 to 9 women in the sample will hold the opinion, we can use the binomial probabilities table or technology to find the individual probabilities of 7, 8, and 9 women holding the opinion, and then add them up.

P(7 to 9) = P(7) + P(8) + P(9)

Using the binomial probabilities table or technology, we can find:

P(7 to 9) = P(7) + P(8) + P(9)

= 0.1223 + 0.0440 + 0.0127

= 0.1790

So the probability that 7 to 9 women in the sample will hold the opinion is 0.1790.

Answers

Answer: i think it b

Step-by-step explanation:

b

The argument is not valid.

The argument commits a fallacy known as the false dilemma or false dichotomy, which presents only two options when there may be more. In this case, the argument assumes that if Superman does not prevent evil, then he must either be impotent or malevolent.

However, there could be other reasons why Superman does not prevent evil, such as a lack of knowledge or resources.

Furthermore, the argument assumes that if Superman exists, then he must either prevent evil or be impotent/malevolent, but this assumption is not necessarily true. It is possible for Superman to exist and not have the ability or inclination to prevent all evil.

Therefore, the conclusion that Superman does not exist does not necessarily follow from the premises. The argument is not valid.

Show that the functions f(x) = x, g(x) = x - 1, and h(x) = x + 3 are linearly dependent. Show, however, that f(x) = x2, g(x) = x - 1, and h(x) = x + 3 are linearly independent

Answers

To show that the functions f(x) = x, g(x) = x - 1, and h(x) = x + 3 are linearly dependent, we need to find a non-zero linear combination of the three functions that equals zero.

Let's assume that a, b, and c are constants such that:

a*f(x) + b*g(x) + c*h(x) = 0

Substituting in the given functions, we get:

a*x + b*(x - 1) + c*(x + 3) = 0

Simplifying this equation, we get:

(a + b + c) * x + (-b + 3c) = 0

For this equation to hold true for all x, we must have:

a + b + c = 0

-b + 3c = 0

This is a system of two equations with three unknowns, which means that we have infinitely many solutions. For example, we could choose a = 1, b = -2, and c = 1, and the equation would hold true. Therefore, we have shown that the functions f(x) = x, g(x) = x - 1, and h(x) = x + 3 are linearly dependent.

Now, let's show that the functions f(x) = x^2, g(x) = x - 1, and h(x) = x + 3 are linearly independent.

We need to show that there are no non-zero constants a, b, and c such that:

a*f(x) + b*g(x) + c*h(x) = 0

Substituting in the given functions, we get:

a*x^2 + b*(x - 1) + c*(x + 3) = 0

This equation holds true for all x if and only if its coefficients are all zero. Therefore, we need to solve the system of three equations:

a = 0

-b + c = 0

3c = 0

The first equation tells us that a must be zero. The third equation tells us that c must be zero. Substituting c = 0 into the second equation, we get:

-b = 0

Therefore, we must have b = 0 as well.

Since a, b, and c are all zero, we have shown that the functions f(x) = x^2, g(x) = x - 1, and h(x) = x + 3 are linearly independent.

How is the sample variance computed differently from the population variance?
only one formula includes a computation for SS

the calculation in the denominator is different
both B and C

Answers

The sample variance computed differently from the population variance is the calculation in the numerator is different and the calculation in the denominator is different

The sample variance is computed differently from the population variance in that the calculation in the numerator is different and the calculation in the denominator is different. Specifically, in the numerator, the sample variance formula includes a computation for SS (sum of squared deviations from the mean), while the population variance formula does not.

Additionally, in the denominator, the sample variance formula divides by n-1 (sample size minus one) instead of by the denominator (population size) in the population variance formula.

The sample variance is computed differently from the population variance in the following ways:

1. The calculation in the numerator is the same for both sample and population variance, as they both involve computing the sum of squared differences (SS) between each data point and the mean.

2. The calculation in the denominator is different. For the population variance, the denominator is the number of data points in the population (N), while for the sample variance, the denominator is the number of data points in the sample (n) minus 1.

So, the correct answer is: the calculation in the denominator is different (Option C).

Here are the formulas for each variance:

Population variance: σ² = Σ(x - μ)² / N
Sample variance: s² = Σ(x - X)² / (n-1)

Answers

The Laplace transform of tJo(t) is s / (s^2 - 1)^(3/2).

To find the Laplace transform of tJo(t), we can use the following formula:

L{t^n f(t)} = (-1)^n F^(n)(s)

where F(s) is the Laplace transform of f(t) and F^(n)(s) denotes the nth derivative of F(s) with respect to s.

Using this formula with f(t) = Jo(t), we have:

L{tJo(t)} = -d/ds [ L{Jo(t)} ]

We can find L{Jo(t)} by using the formula for the Laplace transform of Jo(t):

L{Jo(t)} = 1 / sqrt(s^2 - 1)

Taking the derivative of both sides with respect to s, we get:

d/ds [ L{Jo(t)} ] = d/ds [ 1 / sqrt(s^2 - 1) ]

= (-1/2) (s^2 - 1)^(-3/2) (2s)

= -s / (s^2 - 1)^(3/2)

Substituting this result back into our original equation, we get:

L{tJo(t)} = -d/ds [ L{Jo(t)} ]

= -d/ds [ 1 / sqrt(s^2 - 1) ]

= s / (s^2 - 1)^(3/2)

Therefore, the Laplace transform of tJo(t) is s / (s^2 - 1)^(3/2).
