A new DVD is available for sale in a store one week after its release. The cumulative revenue, $R, from sales of the DVD in this store in week t after its release is R=f(t)=350 ln tR=f(t)=350lnt with t>1. Find f(5), f'(5), and the relative rate of change f'/f at t=5. Interpret your answers in terms of revenue.

**Answer:**

Slope = 2

**Step-by-step explanation:**

Slope =

Slope =

Slope =

Slope = 2

In the given case, we can conclude that The **slope** of the line JK is 2.

To find the slope of the **line** that passes through the points J(-1,-9) and K(5,3), we can use the formula: slope =

The slope of a line is a measure of how steep the line is. It describes the rate at which the **dependent** variable (usually denoted as 'y') changes with respect to a change in the independent variable (usually denoted as 'x').

Plugging in the coordinates, we get:

slope = (3 - (-9)) / (5 - (-1)) = 12 / 6 = 2.

Answer:

Step-by-step explanation:

If you construct a 90% confidence interval for the population proportion and a 95% confidence interval for the population proportion, the 95% confidence will have a wider interval. This is because a higher confidence interval will provide more possible values from which the true value will be determined. Therefore, If you want more confidence that an interval contains the true parameter, then the intervals will be wider.

**Answer:**

**Step-by-step explanation:**

put a point on -5 and put a point on -4 then write the equation on the top to show what you did, name the points then put a point on -9

**Answer:**

x ≥ 1

**Step-by-step explanation:**

Move all terms **not containing x** to the **right side** of the inequality.

−x ≤ −1

Divide **each term** in **−x ≤ −1** by **−1 and simplify.**

x ≥ 1

(b) Explain why the change in population from 1960to 1970 is not the same as the change in population from 1980 to 1990.

(c) Use the model to estimate the population in 2020.

**Answer:**

the answer is below

**Step-by-step explanation:**

**The model** is:

where t is the time in years.

**a)**

- when t=0 (year 1960)

- when t=10 (year 1970)

- when t=20 (year 1980)

- when t=30 (year 1990)

- when t=40 (year 2000)

- when t=49 (year 2009)

**b)**

The change in population from 1960to 1970 is 111071-70751 =40320

The change in population from 1980 to 1990 is 273737-174368=99369

The change from 1960to 1970 is not the same as the change from 1980 to 1990 because the** model function is not linear**, it is *exponential*. Therefore, the rate of the change is not constant.

**c)**

The population in **2020** using the model can be estimated as

when t=60 (year 2020)

**Answer:**

Option A The linear model on tar content accounts for 92.4% of the variability in nicotine content.

**Step-by-step explanation:**

R-square also known as coefficient of determination measures the variability in dependent variable explained by the linear relationship with independent variable.

The given scenario demonstrates that nicotine content is a dependent variable while tar content is an independent variable. So, the given R-square value 92.4% describes that 92.4% of variability in nicotine content is explained by the linear relationship with tar content. We can also write this as "The linear model on tar content accounts for 92.4% of the variability in nicotine content".

The Upper R squared or the coefficient of determination here represents the percentage of the variability in the nicotine content that can be explained by the tar content in the regression model, which in this case is 92.4%.

In this context, the meaning of Upper R squared is represented by option A. The **linear model** on tar content accounts for **92.4%** of the variability in nicotine content. This indicates that 92.4% of the change in nicotine content can be explained by the amount of tar content based on the linear regression model used. This measure is also known as the coefficient of determination. Meanwhile, options B, C, and D are not correct interpretations of the R squared in this context. Both B and D wrongly relate the percentage to the predictability of the data points and option C incorrectly associates this percentage with the residual magnitude.
