The pharmaceutical company uses the quantitative variable to conducts an experiment.

Variables:

A variable is a characteristic of an object. Their values may occur more than once for a set of data. We consider just two main types of variables in this course.

Quantitative Variables - Variables whose values result from counting or measuring something.

Qualitative Variables - Variables that are not measurement variables. Their values do not result from measuring or counting.

Given,

A pharmaceutical company conducts an experiment in which a subject takes 75 mg of a substance orally.

And  the researchers measure how many seconds it takes for one quarter of the substance to exit the bloodstream.

Here we need to find the kind of variable is the company​ studying.

Here the company uses the Qualitative Variable because here they measure the effects of the medicine not the measurement.

So, the experiment uses the Qualitative Variable.

The 90% confidence interval for the true population mean textbook weight is approximately (72.71, 75.29) ounces.

13. The statement that 95% of all the widgets have a width between 14.8 and 34.4 is incorrect. The confidence interval refers to the population mean, not individual widgets.

To construct a confidence interval for the true population mean textbook weight, we can use the formula:

CI = (sample mean) ± (critical value) * (standard deviation / √n)

where:

- Sample mean: 74 ounces (given)

- Critical value: Z-value corresponding to a 90% confidence level (two-tailed test), which can be obtained from the standard normal distribution table or calculator. For a 90% confidence level, the critical value is approximately 1.645.

- Standard deviation: 4 ounces (given)

- n: Number of textbooks in the sample (26)

Calculating the confidence interval:

CI = 74 ± 1.645 * (4 / √26)

  = 74 ± 1.645 * 0.784

  ≈ 74 ± 1.289

  ≈ (72.71, 75.29)

Therefore, the 90% confidence interval for the true population mean textbook weight is approximately (72.71, 75.29) ounces.

Regarding Question 13, the correct interpretations of the interval 14.8 < μ < 34.4 are:

- With 95% confidence, the mean width of all widgets is between 14.8 and 34.4.

- With 95% confidence, the mean width of a randomly selected widget will be between 14.8 and 34.4.

The other two interpretations are incorrect:

- There is not a 95% chance that the mean of a sample of 23 widgets will be between 14.8 and 34.4. Confidence intervals provide information about the population parameter, not about specific sample means.

- The statement that 95% of all the widgets have a width between 14.8 and 34.4 is incorrect. The confidence interval refers to the population mean, not individual widgets.

If you conclude that a soda filling machine is not filling bottles completely based on the results of a sample, it means that the sample of bottles you tested showed evidence of incomplete filling.

However, it is important to note that this conclusion is based on a sample and may not represent the behavior of the entire population of filled bottles.

To make a more reliable conclusion about the filling machine's performance, you would need to conduct a statistical analysis to determine the significance of the observed incomplete filling. This analysis could involve hypothesis testing or confidence interval estimation.

Hypothesis testing allows you to assess whether the observed incomplete filling is statistically significant or could have occurred by chance. You would formulate a null hypothesis, such as "the filling machine fills bottles completely," and an alternative hypothesis, such as "the filling machine does not fill bottles completely." By comparing the sample data to the expected behavior under the null hypothesis, you can determine if there is sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.

The statistical analysis would involve calculating a test statistic, such as a t-test or a z-test, and determining the associated p-value. The p-value represents the probability of observing the sample data or more extreme data if the null hypothesis is true. If the p-value is below a predetermined significance level (e.g., 0.05), you would reject the null hypothesis and conclude that the filling machine is not filling bottles completely.

Additionally, you could also estimate a confidence interval for the proportion of bottles that are filled completely. This would provide a range of values within which the true proportion of completely filled bottles is likely to fall. If the lower limit of the confidence interval is below a desired threshold (e.g., 100%), it would provide further evidence that the filling machine is not consistently filling bottles completely.

It is crucial to note that drawing conclusions based on a sample has inherent limitations. The sample may not accurately represent the entire population of filled bottles, and there is always a margin of error associated with any statistical analysis. Therefore, it is recommended to conduct a larger-scale study or perform ongoing monitoring to obtain more reliable and comprehensive evidence about the filling machine's performance.

In summary, if you conclude that a soda filling machine is not filling bottles completely based on the results of a sample, it is an indication of potential issues with the machine. However, to make a more robust conclusion, you would need to conduct a statistical analysis, such as hypothesis testing or confidence interval estimation, to determine the significance of the observed incomplete filling. This analysis helps account for sampling variability and provides a more reliable assessment of the machine's performance.

Step-by-step explanation:

Answer: it will take 17.5 years to double his money in the account.

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $500

A = 500 × 2 = $1000

r = 4% = 4/100 = 0.04

n = 4 because it was compounded 3 times in a year.

Therefore,.

1000 = 500(1 + 0.04/4)^4 × t

1000/500 = (1 + 0.01)^4t

2 = (1.01)^4t

Taking log of both sides, it becomes

Log2 = 4tlog 1.01

0.301 = 4t × 0.0043 = 0.0172t

t = 0.301/0.0172

t = 17.5 years

Answer:

49.5ft³

Step-by-step explanation:

If it is 2 ft more than 3 times as long as it is wide then:

l = 3w + 2

which means:

w = (l-2)/3

and:

d = 1/2((l-2)/3)

Now just substitute in 11 for l

w = (11 - 2)/3

w = 9/3

w = 3

d = 1/2((11-2)/3)

d = 1/2(9/3)

d = 1/2(3)

d = 1.5

So the total volume is:

The exact values of the remaining trigonometric functions are listed below:

Case 3: cos θ = 3 / 5, tan θ = 4 / 3, cot θ = 3 / 4, sec θ = 5 / 3, csc θ = 5 / 4

Case 4: sin θ = √11 / 6, tan θ = √11 / 5, cot θ = 5√11 / 5, sec θ = 6 / 5, csc θ = 6√11 / 11

Case 5: cos θ = 8√73 / 73, sin θ = 3√73 / 73, tan θ = 3 / 8, cot θ = 8 / 3, csc θ = √73 / 3

Case 6: sin θ = 1 / 2, cos θ = √3 / 2, tan θ = √3 / 3, sec θ = 2√3 / 3, csc θ = 2

In this problem we find four cases of trigonometric functions, whose exact values of remaining trigonometric functions must be found. The trigonometric functions are defined below:

sin θ = y / √(x² + y²)

cos θ = x / √(x² + y²)

tan θ = y / x

cot θ = x / y

sec θ = √(x² + y²) / x

csc θ = √(x² + y²) / y

Now we proceed to determine the exact values of the trigonometric functions:

Case 3: y = 4, √(x² + y²) = 5

x = √(5² - 4²)

x = 3

cos θ = 3 / 5

tan θ = 4 / 3

cot θ = 3 / 4

sec θ = 5 / 3

csc θ = 5 / 4

Case 4: x = 5, √(x² + y²) = 6

y = √(6² - 5²)

y = √11

sin θ = √11 / 6

tan θ = √11 / 5

cot θ = 5√11 / 5

sec θ = 6 / 5

csc θ = 6√11 / 11

Case 5: x = 8, √(x² + y²) = √73

y = √(73 - 8²)

y = 3

cos θ = 8√73 / 73

sin θ = 3√73 / 73

tan θ = 3 / 8

cot θ = 8 / 3

csc θ = √73 / 3

Case 6: x = √3, y = 1

sin θ = 1 / 2

cos θ = √3 / 2

tan θ = √3 / 3

sec θ = 2√3 / 3

csc θ = 2

Answer:

y= -6+2/3x

Step-by-step explanation:

2x-3y=18

Minus the 2x from both sides

-3y=18-2x

Then divide both sides by -1

-3y÷-1=18÷-1 -2x÷-1

Lastly divide both sides by 3

3y÷3= -18÷3+2x÷3

The equation 2x - 3y = 18 can be written as y = (2/3)x - 6 after arranging the terms and making subject y.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation is:

2x – 3y = 18

2x - 3y = 18

-3y = 18 - 2x

y = (2/3)x - 6

Thus, the equation 2x - 3y = 18 can be written as y = (2/3)x - 6 after arranging the terms and making the subject y.

The exponential function that goes through the points (0, 14) and (3, 896) is y = 14·3ˣ. This function has a base of 3 and a coefficient of 14.

An exponential function in the form y =abˣ is a function

where y is equal to a multiplied by b raised to the power of x.

To find the function that goes through the points (0, 14) and (3, 896),

We can write the following equation to find the base of the exponential function that goes through the points (0, 14) and (3, 896):

b³ = 896/14

We can then solve for b by taking the cube root of both sides of the equation to get:

b = 3

Now that we know the base of the function, we can use the point (0, 14) to find the value of the coefficient a.

Since the x-value of this point is 0, we can plug 0 in for x in the exponential function y=abˣ to get:

y = ab⁰ = a

Since the y-value of the point (0, 14) is 14, we can set this equal to a to solve for the value of a:

a = 14

So, the exponential function is y = 14·3ˣ

Answer:

Step-by-step explanation:

If Mrs. Burdell​'s storage container is 3 feet​ long, 2 feet​ wide, and 8 feet tall, then the volume of the strorage container is expressed as shown;

Volume = Length *Breadth * Height

Volume of the container = 3*2*8 = 48ft³

If she each boxes she is to fit into the storage container has a volume of 1ft³, the total number of boxes she can fit into the container is expressed as:

Number of container = volume of the storage container/volume of a container

= 48ft³/1ft³

= 48 boxes

Since she can fit 48 boxes successfully in her storage tank, then she can fit 44 boxes as well into the storage tank since the total number of boxes the tank can take is greater tan the proposed amount of boxes in question.

So, yes she  fit 44 boxes if each has a volume of 1 cubic foot in her container
