The area swept clean by the wiper blade is 221.128 square inches.

To find the area swept clean by the wiper blade, we can calculate the area of the sector of a circle that the blade moves through.

The radius of the circle that the blade moves through is the length of the arm, which is 19 inches.

The angle that the blade moves through is 105 degrees.

To calculate the area of the sector, we need to convert the angle to radians:

105 degrees * (π/180) = 1.8326 radians (rounded to 4 decimal places)

The area of the sector is then:

(1/2) * r^2 * θ = (1/2) * (19^2) * 1.8326 = 325.628 square inches (rounded to 3 decimal places)

However, the area swept clean by the wiper blade is not the full area of the sector, as the blade itself has a width of 11 inches. Therefore, we need to subtract the area of the triangle formed by the blade and the two radii of the sector that intersect at the blade's pivot point.

The length of one of the radii is the length of the arm, which is 19 inches. The length of the other radius is 19 - 8 = 11 inches since the blade is mounted 8 inches from the pivot point.

Using the formula for the area of a triangle:

(1/2) * base * height = (1/2) * 11 * 19 = 104.5 square inches

Therefore, the area swept clean by the wiper blade is:

325.628 - 104.5 = 221.128 square inches (rounded to 3 decimal places)

So the area swept clean by the wiper blade is approximately 221.128 square inches.

Given statement solution is :- The correlation coefficient between weight and spending is approximately 0.5.

To calculate the correlation coefficient (also known as the Pearson correlation coefficient), you need to follow these steps:

Calculate the mean (average) of both the weight and spending data.

Calculate the difference between each weight measurement and the mean weight.

Calculate the difference between each spending measurement and the mean spending.

Multiply each weight difference by the corresponding spending difference.

Calculate the square of each weight difference and spending difference.

Sum up all the products from step 4 and divide it by the square root of the product of the sum of squares from step 5 for both weight and spending.

Round the correlation coefficient to an appropriate number of decimal places.

Here's an example using sample data:

Weight (in pounds): 150, 160, 170, 180, 190

Spending (in dollars): 50, 60, 70, 80, 90

Step 1: Calculate the mean

Mean weight = (150 + 160 + 170 + 180 + 190) / 5 = 170

Mean spending = (50 + 60 + 70 + 80 + 90) / 5 = 70

Step 2: Calculate the difference from the mean

Weight differences: -20, -10, 0, 10, 20

Spending differences: -20, -10, 0, 10, 20

Step 3: Multiply the weight differences by the spending differences

Products: (-20)(-20), (-10)(-10), (0)(0), (10)(10), (20)(20) = 400, 100, 0, 100, 400

Step 4: Calculate the sum of the products

Sum of products = 400 + 100 + 0 + 100 + 400 = 1000

Step 5: Calculate the sum of squares for both weight and spending differences

Weight sum of squares: (\(-20)^2 + (-10)^2 + 0^2 + 10^2 + 20^2\)= 2000

Spending sum of squares: \((-20)^2 + (-10)^2 + 0^2 + 10^2 + 20^2\) = 2000

Step 6: Calculate the correlation coefficient

Correlation coefficient = Sum of products / (sqrt(weight sum of squares) * sqrt(spending sum of squares))

Correlation coefficient = 1000 / (sqrt(2000) * sqrt(2000)) = 1000 / (44.721 * 44.721) ≈ 1000 / 2000 = 0.5

Therefore, the correlation coefficient between weight and spending in this example is approximately 0.5.

Complete question is:

A study wants to determine the average tuition that san jose state undergraduate students would pay per semester. each student in the following samples is asked how much tuition he or she paid for the fall semester. what is the type of sampling in each case?

A sample of 100 undergraduate San Jose State students is taken by organizing the students’ names by classification (freshman, sophomore, junior, or senior), and then selecting 25 students from each.

The standard deviation of the sampling distribution of the sample means will be equal to the standard deviation of the population divided by the square root of the sample size. Therefore, if the population standard deviation is 50 and the sample size is 25, then the standard deviation of the sampling distribution of the sample means will be 10.

The Central Limit Theorem (CLT) states that the sampling distribution of the sample means will approach a normal distribution as the sample size increases, regardless of the shape of the population distribution. This means that even if the population distribution is not normal, the distribution of the sample means will still be approximately normal as long as the sample size is sufficiently large (usually, a sample size greater than or equal to 30 is considered large enough).

Additionally, according to the CLT, the mean of the sampling distribution of the sample means will be equal to the mean of the population from which the samples are drawn. In this case, since the population mean is 150, the mean of the sampling distribution of the sample means will also be 150.

Step-by-step explanation:

The solution to the given differential equation is L⁻¹{Y(s)} = (b³ t sin 2t) / (2 (sin bt - bt cos bt))

To solve the differential equation using the convolution theorem, we'll follow these steps:

Take the Laplace transform of both sides of the differential equation.

Use the convolution theorem to simplify the resulting expression.

Take the inverse Laplace transform to obtain the solution in the time domain.

Let's start with step 1:

Given differential equation: d²y/dt² - 4y = t cos 2t

Taking the Laplace transform of both sides, we get:

s²Y(s) - sy(0) - y'(0) - 4Y(s) = L{t cos 2t}

Where Y(s) represents the Laplace transform of y(t), y(0) is the initial condition for y(t) at t = 0, and y'(0) is the initial condition for dy/dt at t = 0.

The Laplace transform of t cos 2t can be found using the Laplace transform table:

L{t cos 2t} = -Im{d/ds[1 / (s² - (2i)²)]}

= -Im{d/ds[1 / (s² + 4)]}

= -Im{(-2s) / [(s² + 4)²]}

= 2Im{(s) / [(s² + 4)²]}

Now let's simplify the expression using the convolution theorem:

The Laplace transform of the convolution of two functions, f(t) and g(t), is given by the product of their individual Laplace transforms:

L{f * g} = F(s) G(s)

In our case, f(t) = y(t) and g(t) = 2Im{(s) / [(s² + 4)²]}.

Therefore, F(s) = Y(s) and G(s) = 2Im{(s) / [(s² + 4)²]}.

Multiplying F(s) and G(s), we get:

Y(s) G(s) = Y(s) 2Im{(s) / [(s² + 4)²]}

Now, we can rewrite the left-hand side of the equation using the convolution theorem:

Y(s) * 2Im{(s) / [(s² + 4)²]} = L{t cos 2t}

Taking the inverse Laplace transform of both sides, we have:

L⁻¹{Y(s) * 2Im{(s) / [(s² + 4)²]}} = L⁻¹{L{t cos 2t}}

Simplifying the right-hand side using the inverse Laplace transform table, we get:

L⁻¹{Y(s) * 2Im{(s) / [(s² + 4)²]}} = t sin 2t / 4

Now, we can apply the convolution theorem to the left-hand side of the equation:

L⁻¹{Y(s) * 2Im{(s) / [(s² + 4)²]}} = L⁻¹{Y(s)} * L⁻¹{2Im{(s) / [(s² + 4)²]}}

The inverse Laplace transform of 2Im{(s) / [(s² + 4)²]} can be found using the inverse Laplace transform table:

L⁻¹{2Im{(s) / [(s² + 4)²]}} = 1 / 2b³ (sin bt - bt cos bt)

Therefore, we have:

L⁻¹{Y(s)} * 1 / 2b³ (sin bt - bt cos bt) = t sin 2t / 4

From this, we can deduce the inverse Laplace transform of Y(s):

L⁻¹{Y(s)} = (t sin 2t / 4) / (1 / 2b³ (sin bt - bt cos bt))

Simplifying further:

L⁻¹{Y(s)} = (b³ t sin 2t) / (2 (sin bt - bt cos bt))

This is the solution to the given differential equation.

If adding two positive integers results in a negative number, it means that an overflow has occurred. The overflow flag is set when the result of an operation is too large to be represented with the given number of bits.
If bx and dx both contain positive integers and adding them produces a negative result, the overflow flag will be set. This is because when two positive integers are added, the result should also be a positive integer. If the result is negative, it means there was an overflow during the addition process, and the overflow flag will be set to indicate this issue.
