The average value of the function f(x) = (x + 2) on the interval [0, 3] is 7/2.

Calculate the definite integral of the function over the interval [a, b], then divide it by the interval's length (b - a), in order to determine the average value of a function f(x) over the interval.

Given that the interval is [0, 3] and the function f(x) = (x + 2), we have:

= (1/3) × [1/2 x² + 2x] evaluated from x=0 to x=3

= (1/3) × [(1/2 × 3² + 2×3) - (1/20² + 20)]

= (1/3) × [(9/2 + 6) - 0]

= (1/3) × (21/2)

= 7/2

The estimated regression equation for estimating the price of a bicycle given its weight is: Price = 23.20 * Weight - 388.50.

To develop an estimated regression equation, we use the given data on weight and price of bicycles. We assume a linear relationship between weight (x) and price (y). The estimated regression model can be obtained through regression analysis.

Using statistical software or a calculator, we perform the regression analysis on the data. The estimated regression equation is in the form:

y = a * x + b

where "a" represents the slope and "b" represents the intercept of the regression line.

Based on the analysis, we find that the slope (a) is 23.20 and the intercept (b) is -388.50.

Therefore, the estimated regression equation for estimating the price of a bicycle given its weight is: Price = 23.20 * Weight - 388.50.

The estimated regression equation, Price = 23.20 * Weight - 388.50, can be used to estimate the price of a bicycle based on its weight. The positive slope coefficient of 23.20 indicates that as the weight of the bicycle increases, the price tends to increase as well. However, it is important to note that regression analysis assumes a linear relationship, and other factors not accounted for in the model could also influence the price of the bicycles.

150 students scored between 42 and 56 on the district geometry test.

Box whisker plots are used to abstract a collection of data that has been approximated using an interval scale. Just a box plot is another name for it. They are mostly employed while interpreting data. It is one of the graphical approaches that shows how the dataset's data varies from one another. The histogram may be used to display the data as well. Yet a histogram offers a useful presentation. Box and whisker plots are preferable to histograms because they may exhibit numerous sets of data on a single graph, which adds more information.

From the box whisker plot we see that the lower quartile is 42 and the median is 56.

The median represents the 50th percentile whereas lower quartile is 75%.

The difference is:

75 - 50 = 25%.

Now, for 600 scores we have:

Here, we want to write the equation of the quadratic function

We have the general form as:

from the question, we have the horizontal intercepts at t= 3 and t =4

that means (t-3) is a factor and also (t-4) is another root of the equation

The product of these two is as follows:

Finally, we need to find the value of a

We can do this by making a substitution

We substitute 1 for t and -3 on the other side of the equation

Mathematically, we have this as:

Thus, we have the equation as:

Answer:

y = -8x + 10

Step-by-step explanation:

y = -8x + b

2 = -8(1) + b

2 = -8 + b

10 = b

9514 1404 393

Answer:

  y = -8x +10

Step-by-step explanation:

The y-intercept can be found from the equation ...

  b = y -mx

Using the given point and slope, this is ...

  b = 2 -(-8)(1) = 10

Then the slope-intercept equation is ...

  y = mx +b

  y = -8x +10

(a) a= -45.43 and b = 40.06 and (b) R² = 0.56

(c) the variation in the independent sample values of weekly gross revenue

Y= - 42.57 + 22.40X₁ + 19.50X₂

a) Using X: TV Advertising Volume as the independent variable, you need to test simple linear regression.

The first step is to estimate the regression model

E(Yi) = α + βXi

Then ^Yi = a + bXi

where "a" is the estimate of the intercept and "b" is the estimated slope of the intercept.

Using statistical software, I calculated a simple linear regression as follows:

a= -45.43

b= 40.06

^Yi= -45.43 + 40.06Xi

To test whether there is a significant relationship between TV advertising and total weekly income, one needs to test the population slope of the regression, assuming:

H₁: β ≠ 0

α: 0.05

We have two ways to test if the regression is significant, you can use two-tailed t-test or one-tailed F-test. They are two different distributions and tests, but you can get the same result.

I will use a t-test for this item and an F-test for later tests.

 t = b-β/Sb × t(n-2)

\(t_{H0} = \frac{40.06 -0}{14.64} = 2.74\)

The p-value for this test is 0.0339

Using the p-value method, the decision rule is:

If the p-value ≤ α, the decision to reject the hypothesis is .

Decided not to reject the null hypothesis if the value of p > α.

p-value: 0. 0339 is less than α: 0.05, we decide to reject the null hypothesis. conclude that there is a significant relationship between television advertising and the sample total weekly revenue.

Looking at the estimated value of the slope, these two variables can have a direct relationship, namely

With each additional TV advertising volume, the total weekly revenue also increases. (This is just a hypothesis, without proper hypothesis testing you cannot draw any conclusions)

b) To find out what percentage of the change in total weekly income is explained by the model, you need to calculate the coefficient of determination.

For item a), the coefficients are:

R²= 0.56

This means that 56% of the variability in total weekly income is explained by the amount of television advertising according to the estimated model: ^ Yi= -45 .43 + 4.06Xi

c) This time you need to formulate the regression equation with two independent variables, namely:

X₁: Volume of TV ads

X₂: Volume of newspaper ads

The model will be

\(E(yi) = \alpha +\beta _{1} X_1 +\beta _{2} X_2\)

The model is ^Y = -42.57 + 22.40X₁ + 19.50X₂

For this hypothesis test, it is better to use the F-test

1) Intersection

H₀: α = 0

H₁: α ≠ 0

\(t_{H0} =-1.49\)

The p-value is greater than the significance level and it is decided not to reject the null hypothesis.

2) Slope of X₁

H₀: β₁ = 0

H₁: β₁≠0

α: 0.05

\(t_{H0} = 3.16\)

The 4th value is less than the null hypothesis for decision rejection.

Using a 5% significance level, the regression is significant.

3) Slope for X₂

H₀: β₂ = 0

H₁: β₂ ≠ 0

α: 0.05

\(t_{H0} = 5.27\)

e) The number of newspaper advertisements will affect the average weekly gross income.

d) The multivariate regression corresponds to a coefficient of determination of R²= 0.9393% of the variability of the average weekly gross income is explained by the combined volume of TV and newspaper advertisements under the estimated model:

Y= - 42.57 + 22.40X₁ + 19.50X₂

By comparing the results in a) and c), we can say that the two independent variables explain the dependent variable well.

Comparing the R² of the two, it can be said that TV advertising volume alone does not explain the fluctuation in total weekly income very well, but together with newspaper advertising volume, it becomes a good explanatory variable .

After 2.10 years, there will be 8 grams of radioactive substance left.

The rate of decay of a radioactive substance is proportional to the amount of substance present.

Thus, we can conclude that the quantity of the radioactive substance present decreases exponentially over time.

A radioactive decay constant is defined as the fraction of the substance that decays in a unit of time, t.

According to the given statement, the rate of decay of a radioactive substance is proportional to the amount of substance present.

Suppose that the quantity of radioactive substance present initially is A0.

Then, the decay constant is represented by λ.

As the substance continues to decay, the remaining amount of the substance present after time t can be given by the exponential decay equation:  A(t) = A0e-λt

where A(t) represents the amount of substance present after time t.

In this problem, we are given that 12 grams of the substance were initially present, and now there are 8 grams. Therefore, we need to find out the value of t using the given data.

For this, we can use the exponential decay equation:  A(t) = A0e-λt

Let's assume that the amount of the substance present after time t is A(t) = 8 g, A0 = 12 g

Thus, the equation becomes 8 = 12e-λt

To find the value of λ, we can rearrange the equation and take the natural logarithm on both sides:

ln (8/12) = ln (e-λt)ln (8/12)

= -λt ln (e)ln (8/12)

= -λt λ = -ln (8/12)/t λ = ln (12/8)/t λ = 0.2877/t

Since we now know the value of λ, we can substitute the values of A0 and λ in the exponential decay equation to find the value of t.

A(t) = A0e-λtA(t) = 12e-0.2877/t

A(t) = 8 (Given)

Therefore, 8 = 12e-0.2877/t 0.6667 = e-0.2877/t

Taking natural logarithm on both sides, we get:

ln (0.6667) = ln (e-0.2877/t)ln (0.6667)

= -0.2877/t ln (e)ln (0.6667)

= -0.2877/t t

= -0.2877/ln (0.6667) t
