The maximum error in calculating the area of the disk is approximately 0.25 cm * 2π * 26 cm = 16.3 cm².

The maximum error in the calculated area of the disk can be estimated using differentials. A = r2, where r is the circle's radius, is the formula for calculating a circle's area.. Differentiating this equation with respect to r gives us A' = 2πr. Plugging in the given values, we get A' = 2π * 26 cm = 161.6 cm². If the possible error in measuring the radius is 0.25 cm, then the maximum error in calculating the area of the disk is 0.25 cm * A' = 0.25 cm * 161.6 cm² = 16.3 cm². Therefore, the maximum error in the calculated area of the disk is approximately 16.3 cm².

You can assess normality of data using D. Pearson's Measure of Normality

Pearson's Measure of Normality, also known as Pearson's Test for Normality, is a statistical test that is used to assess whether a set of data is normally distributed.

It is based on the skewness and kurtosis of the data, and it provides a p-value which indicates the probability that the data is from a normal distribution. Pearson's test is considered as one of the most common statistical test used to check normality of data.

Answer: To convert a temperature from degrees Celsius (°C) to degrees Fahrenheit (°F), you can use the following formula:

°F = (9/5) x °C + 32

So, to convert 280°C to °F:

°F = (9/5) x 280 + 32 = 536 + 32 = 568°F

So the equivalent of 280°C in °F is 568°F

In the United States, the upper class, or capitalist class, is estimated to comprise about 1 percent of the population.

This is according to the social class model developed by Gilbert and Kahl, which is based on the theory of Weber.

This model suggests that the upper class is made up of those who own the majority of the nation's wealth and power, and are thus able to influence governmental decisions.

While the upper class may be small in size, it is highly influential and its members often have the resources to enact large-scale change.

On the interval (1,b), f(x)=4x2-7 changes at an average rate of 8b-11. To determine this, divide the difference between the function at b and 1 (4b2-7-3) by the difference between the intervals (b-1).

The average rate of change of a function on an interval is a measure of the change in the output of the function over the given interval. It can be calculated by taking the difference of the output between the endpoints of the interval, and dividing by the difference between the endpoints of the interval. For the given function f(x)=4x²-7 on the interval (1,b), the average rate of change is 8b-11This is obtained by dividing the output difference between 1 and b (4b2-7-3) by the output difference between the intervals (b-1). Our average rate of change is given by this formula: (4b2-7-3) / (b-1) = 8b-11. This average rate of change provides us with a general understanding of the function's rate of change across the specified interval. The output of the function increases at a constant rate as the input increases in this situation because the rate of change grows linearly as b increases.

The total amount of interest due on the account is $8.36.

What is the simple interest?

Simple interest is a method of calculating the interest on a loan or deposit. It is calculated as the principal amount multiplied by the interest rate, multiplied by the number of time periods (usually in years).

To calculate the interest due on the account, we first need to determine the number of days for which the interest will accrue. Since the payment was made on the 9th day and the charge was made on the 28th day, the interest will accrue for 28 - 9 = 19 days.

We then use the formula for simple interest: Interest = Principal x Rate x Time

In this case, the Principal is the beginning balance of $660, the Rate is the APR of 26% (which must be converted to a decimal by dividing by 100), and the Time is the number of days for which the interest will accrue (19 days).

So the Interest = $660 x 0.26 x (19/365) = $8.36

Therefore, the total amount of interest due on the account is $8.36.

A walkway around a rectangular garden.

The garden's size is 4(4.5 x + 1.5) square meters.

The garden's and the walkway's combined area is 5.5(8 x + 4)

We must locate the location of the walkway.

By deducting the size of the pathway from the area of the

from the combined area, a rectangle

Simplify it to provide the combined area as 5.5(8 x + 4)

The total area is equal to 5.5(8 x) Plus 5.5. (4)

∴Area added together: 44 x + 22

Simplify: The garden's area is 4(4.5 x + 1.5).

The garden's size is equal to 4(4.5 x) Plus 4. (1.5)

The garden's size is equal to 18 x + 6.

Subtract the garden's area from the total area now.

The walkway's area is equal to (44 x + 22) minus (18 x + 6)

Area of the walkway is equal to 44x + 22 - 18 x - 6

the proportion of viewers who watch the particular show is less than 0.20. The p-value of 0.47 is greater than the level of significance of 0.05, meaning that the results of the test are not statistically significant and do not provide enough evidence to reject the null hypothesis that the proportion of viewers who watch the particular show is greater than or equal to 0.20.

At the locations where the acceleration graph veers off, the particle changes course. It accelerates at positive slope acceleration graph intervals and decelerates during negative slope acceleration graph intervals.

At the locations where the acceleration graph veers off, the particle changes course. At these locations, the particle's acceleration is zero and the slope of the graph flip-flops from positive to negative. The particle changes direction at this point. The particle either speeds up or slows down in the intervals before and after the point of inflection. The particle is speeding up during the intervals where the acceleration graph has a positive slope, and slowing down during the intervals where the acceleration graph has a negative slope. We can determine how the particle is changing direction and whether it is speeding up or slowing down by examining the slope of the acceleration graph.
