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.

Another presentation that is similar to a histogram is a stemplot. In statistics, a stemplot is a tool for presenting quantitative data in a graphical format, similar to a histogram, namely to assist in visualizing the shape of the data distribution which is often used in exploratory analysis. Stemplots were introduced by Arthur Bowley in the early 1900's. However, its general use only began in 1980 after John Tukey's published Exploratory Data Analysis in 1977.

Stem-and-leaf plots provide more information about true values than histograms. As in a histogram, the length of each bar corresponds to the number of events that fall into a given interval. On Histograms. we can only see the frequency value of the data but we don't know what the actual number value is. In contrast to the histogram, in SLP besides we can know the frequency value, we can also know what the actual data value is. This is done by dividing the observed values into two components, stem and leaf.

Quantitative variables can be used to measure and contrast data because they have numerical values. Measurements like shoe size, height, weight, and temperature are examples of quantitative variables.

Quantitative variables can be used to measure and contrast data because they have numerical values. They come in discrete or continuous forms. While continuous variables have an infinite number of possible values, such as decimal numbers, discrete variables have specific values, such as integers or whole numbers. Measurements like shoe size, height, weight, and temperature are examples of quantitative variables. Quantitative variables can be used to describe a population's varied characteristics, such as the median age or annual income of a given group. The average height of men and women, for example, might be used to compare two populations. The use of quantitative variables is crucial for comprehending and analyzing data. They enable academics to spot patterns and trends in data They enable researchers to find patterns and trends in data, anticipate the future, and form conclusions.

a. (-1,5) is on the parabola

b. (1,7) is NOT on the parabola

c. (3,9) is NOT on the parabola

a. (-1,5)

The distance from the point (-1,5) to the focus (-1,6) is sqrt((-1-(-1))^2 + (5-6)^2) = sqrt(0+1) = 1

The distance from the point (-1,5) to the directrix y=4 is the absolute value of the y-coordinate of the point - the y-coordinate of the directrix = abs(5-4) = 1

Since the distances are equal, the point (-1,5) is on the parabola.

b. (1,7)

The distance from the point (1,7) to the focus (-1,6) is sqrt((1-(-1))^2 + (7-6)^2) = sqrt(2^2 + 1^2) = sqrt(5)

The distance from the point (1,7) to the directrix y=4 is the absolute value of the y-coordinate of the point - the y-coordinate of the directrix = abs(7-4) = 3

Since the distances are not equal, the point (1,7) is not on the parabola.

c. (3,9)

The distance from the point (3,9) to the focus (-1,6) is sqrt((3-(-1))^2 + (9-6)^2) = sqrt(4^2 + 3^2) = sqrt(16+9) = sqrt(25)

The distance from the point (3,9) to the directrix y=4 is the absolute value of the y-coordinate of the point - the y-coordinate of the directrix = abs(9-4) = 5

Since the distances are not equal, the point (3,9) is not on the parabola.

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.

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.

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 G.C.F. of the expression 16n - 24 is evaluated to be 8(2n - 3).

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is - 16n - 24.

The greatest common factor, which is the product of two or more numbers, is the largest number (GCF). A natural number is created by dividing them by the biggest number (factor).

First of all find the G.C.F of 16n and 24 separately.

It can be written that -

16n = 2 × 2 × 2 × 2 × n

24 = 2 × 2 × 2 × 3

The common prime factor between the two is 2 × 2 × 2 = 8.

So, the GCF of 16n and 24 is 8.

Now use the GCF to factor the expression -

= 16n - 24

= 8(2n) - 8(3)

Using the distributive property -

= 8(2n) - 8(3)

= 8(2n - 3)

Therefore, the GCF value is 8(2n - 3).
