Sum, product, power and quotient is the combination of limit properties tat is required to evaluate the given expression.

An output value that a function approaches for the specified input values is referred to as a limit. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity.

The limit of the difference between two functions is equal to the difference between the limits of two functions, according to the difference law for limits. The law of constant multiples for limits states that the limit of a function that is a constant multiple is equal to the sum of the limits of the function and the constant.

We must understand how to obtain the limits involving sums in order to evaluate this limit. We also require the power rule because powers are involved. Because the fraction can be expressed as a product with a negative power, we apply the product rule rather than the quotient rule.

The average duration of a customer's stay in the restaurant is approximately 27 seconds.

To find the average time a customer spends in the restaurant, we divide the total time spent by the total number of customers. Given that the outlet processes 2000 customers in 15 hours and there are 50 customers in the restaurant on average, we can calculate the average time as follows:

Total time spent = 15 hours

Total number of customers = 2000

Average time per customer = Total time spent / Total number of customers

= 15 hours / 2000

= 0.0075 hours or 27 seconds.

a. The most typical case is desired: Mode. The mode is a useful measure of central tendency when the most typical or common value is of relevance since it denotes the value or category that occurs most frequently in a data collection.

b. The distribution is open-ended: Median. The median is the middle value in a data set when arranged in ascending or descending order. It is a suitable measure of central tendency when the distribution is open-ended or skewed, as it is less affected by extreme values compared to the mean.

c. The data collection has an extreme value: the median. The median is less sensitive to extreme values compared to the mean, making it a better measure of central tendency in data sets with extreme values or outliers.

d. The data are categorical: Mode. The mode is appropriate for categorical data, as it represents the most frequently occurring category or value in the data set.

e. Further statistical computations will be needed: This statement does not indicate a specific measure of central tendency. Further statistical computations may be needed to determine the appropriate measure of central tendency depending on the characteristics of the data and the specific objectives of the analysis.

f. The numbers should be split into two roughly equal groups, one of which should contain the higher values and the other should contain the smaller values: Median.  The median is the value that separates a data set into two equal halves, making it suitable for dividing data into two approximately equal groups based on their values.

Answer:

Surface Area = 2 * (length * width + length * height + width * height)

Step-by-step explanation:

To find the surface area of a rectangular solid (also known as a rectangular prism), you need to calculate the areas of its six faces and then add them together. The formula for the surface area of a rectangular solid is:

Surface Area = 2 * (length * width + length * height + width * height)

Here are the steps to find the surface area:

Identify the length, width, and height of the rectangular solid.

Multiply the length by the width to find the area of the top and bottom faces.

Multiply the length by the height to find the area of the front and back faces.

Multiply the width by the height to find the area of the left and right faces.

Add up all the areas calculated in steps 2, 3, and 4.

Multiply the sum by 2 to account for the two identical sets of faces.

The result will be the surface area of the rectangular solid.

It's important to note that all measurements should be in the same unit (e.g., centimeters, inches) for accurate results.

Answer:

Step-by-step explanation:

The area of ​​the rectangular solid (parallelepiped) is calculated by adding the lateral area and twice the base area: Stot=Slat+2Sb; the area of ​​the rectangular parallelepiped is given by the sum of the areas of the six rectangles that make up its surface, ie Stot=2(ab+ah+bh).

By using the fact that the sum of the interior angles of a triangle must be 180°, we will get:

Remember that the sum of the internal angles of a triangle is always equal to 180°, then we can write:

m∠B + m∠C + m∠D = 180°

Then:

13x - 35 + 5x - 19 + 2x + 14 =180

20x -40 = 180

20x = 180 + 40

20x = 220

x = 220/20

x = 11

Now that we know the value of x, we can find the measures of the angles.

m∠B = (13x- 35)° = (13*11 - 35)° = 108°

m∠B = (5x - 19)° = (5*11 - 19)° = 36°

⭐What is a property of a perpendicular line?

⭐What does "opposite reciprocal" mean?

⭐What is the equation of a line?

To create the equation of the perpendicular line, let's first find the slope of the perpendicular line.

The equation of the line the perpendicular line is perpendicular to is:

\(-x + y = 9\)

⭐ \(y = x + 9\)

The slope of the line the perpendicular line is perpendicular to is 1.

Therefore, the slope of the perpendicular line is -1.

Substitute the slope of the perpendicular line into the equation of the perpendicular line:

\(y = mx + b\)

\(y = -x + b\)

Now, we need to find the y-intercept of the perpendicular line.

To do so, substitute a point that we are given into the perpendicular line equation and solve for b.

I am going to use the point (-2,-1), because we are given this point.

\(y = -x + b\)

\(-1 = -(-2) + b\)

\(-1 = 2 + b\)

\(-3 = b\)

Therefore, the y-intercept of the perpendicular line is -3.

Substitute the value of the y-intercept into the equation of the perpendicular line:

\(y = -x -3\)

∴The equation of the perpendicular line is \(y = -x -3\)

The interest amount (simple interest ) on the loan amount $5315 at 5% from 10th aug to 23rd dec. of same year is $105.50

If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

\(I = \dfrac{P \times R \times T}{100}\)

For this case, we're specified that:

Converting this time in terms of year, we get:

Aug has 31 days, Sept has 30 days, Oct. has 31 days, Nov has 30 days.

From 10th aug, till its last, there went 22 days.

Whole sept and oct and nov. was spent (30+31+30 = 91 days)

And then there were 22 days of december(23rd day not covered assumingly)

So, total days = 22+22+91 = 145 days.

Assuming averagely 365.25 days in an year, we get the average time for which the interest will be calculated as:

\(\dfrac{145}{365.25} \approx 0.397 \: \rm years\)

Thus, we get: the amount of interest as:

\(I = \dfrac{P \times R \times T}{100}\\\\I \approx \dfrac{5315 \times 5\times 0.397}{100} \approx 105.50 \: \rm dollars\)

The probability of getting exactly one face card is 0.72.

According to the questions two cards are drawn from a deck.

Since, we know that

Total number of cards in a deck = 52

Total number of face cards =  3 × 4 = 12

So, the number of ways of selecting 2 cards from a deck = \(^{52} C_{2}\)

And, the total number of ways of  getting exactly one face cards

= \(^{12} C_{1} \times ^{40} C_{1}\)  + \(^{40} C_{1} \times ^{12} C_{1}\)

= 2\(^{40} C_{1} \times ^{12} C_{1}\)

Therefore, the probability of getting exactly one face card

= \(\frac{2(^{40} C_{1} \times ^{12} C_{1})}{^{52C_{2} } }\)

The outer diameter of the thin-walled pipe can be calculated by adding twice the thickness to the inner diameter. Therefore, the outer diameter is 0.5 in + 2(0.025 in) = 0.55 in.

A thin-walled pipe is a hollow cylinder with a relatively small thickness compared to its inner and outer diameters. In this case, the inner diameter of the pipe is given value as 0.5 in, and the thickness is 0.025 in.

To find the outer diameter, we add twice the thickness to the inner diameter. This is because the thickness is divided equally on both sides of the inner diameter. So, the outer diameter can be calculated as 0.5 in + 2(0.025 in) = 0.55 in.

The outer diameter is an important parameter in determining the overall size and structural integrity of the pipe. It affects the flow capacity, strength, and compatibility with other pipe fittings.

Knowing the outer diameter allows for proper sizing and fitting of the thin-walled pipe in various applications, such as plumbing, HVAC systems, or fluid transportation.
