All the above can represent stable interhalogen compounds. Interhalogen compounds are formed when different halogens combine with each other.

The general formula for interhalogen compounds is given by XYn, where X and Y represent different halogens, and n represents the number of Y atoms bonded to the X atom. The interhalogen compounds can have different stoichiometries, resulting in different values of n. Therefore, all the given formulas, XY, XY2, XY3, and XY5, can represent stable interhalogen compounds, depending on the specific combination of halogens and their bonding arrangements.

Hence, none of the given formulas does not exist for interhalogen compounds, as all of them can be valid representations of stable interhalogen compounds.

Area for cross-section is 615.7521601cm

Step-by-step explanation:

area of a circle = πr²

π × radius²

In this question, the radius is 14, so you need to square it giving 196.

Then multiply by π = 615.7521601cm (round if necessary)

Answer:

A total of  

360

people were surveyed. Of the people surveyed,  

70

said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is  

60

%. The percentage of early birds who prefer to drink tea is  

49

%.

Step-by-step explanation:

The last row and the last column give the total number of people surveyed, which is 360.

The joint frequency of the Early Bird column and the Tea row show that 70 people said they were an early bird and preferred tea.

To get the percentage of night owls, divide the total number of night owls by the total number of people surveyed and multiply by 100:

To get the percentage of early bird tea drinkers, divide the joint frequency of early birds and tea by the marginal total number of early birds and multiply by 100:

From total of 360 people surveyed, 70 people are early birds and preferred tea. Hence night owls is 60% and people who prefer to drink tea is 49%

A survey is a method of data collection and can be in the form of questionnaires and interviews. The survey tells us about the demands and needs of the people.

As per the question, the last row and column give us a total of 360. Those who are early birds and take tea are 70% of the population. To get the percentage we need to X night owls by the number of people surveyed multiplied by 100.

For the early bird tea, the total frequency of early birds by the marginal total number of early birds multiplied by 100.

Therefore,  subscript indices must be either positive integers or logical. True

Explanation: The statement "subscript indices must be either positive integers or logicals" is true. Subscript indices are used to identify elements in an array. A positive integer subscript identifies a particular element in an array, while a logical subscript identifies a subset of elements based on a logical condition. For example, if we have an array A, then A(1) would identify the first element of the array, while A(A > 0) would identify all elements in the array that are greater than zero. Subscript indices cannot be negative or non-integer values.

Therefore,  subscript indices must be either positive integers or logical. True

Given that the average waiting time for a customer's call to be answered by a company representative is 20 minutes.

Let x be the median waiting time.

The exponential distribution is used to model the waiting time of the customer's call to be answered by a company representative.

The exponential probability density function (PDF) is given byf(x) = λe^(-λx)

where, λ = 1 / 20 = 0.05 (as the average waiting time is 20 minutes)

Now, we need to find the median waiting time, which means that

P(x ≤ median waiting time) = 0.5It can be calculated as:

P(x ≤ x median) = 0.5=> ∫₀^(x median) \(f(x)dx = 0.5= > ∫₀^\)(x median) λe^(-λx)dx = 0.5

Now, integrating λe^(-λx) w.r.t. x, we get\(-λe^(-λx) / λ |_0^\)(x median) = 0.5=> -e^(-0.05x median) + 1 = 0.5=> e^(-0.05x median) = 0\(.5= > ln e^(-0.05x\) median) = ln 0.5=> -0.05x median = ln 0.5=> x median = -ln \(0.5 / 0.05≈\)13.86 minutes

What is simple interest?

Simple interest is a method of calculating interest on a principal amount, where the interest is calculated only on the original amount of the loan or investment, without taking into account any interest that may have been previously earned.

To calculate the total amount of money you will pay back when you borrow $900 for eight years at an annual interest rate of 8%, we need to use the simple interest formula:

Simple Interest = (P × R × T) / 100

where,

P = Principal amount (the amount borrowed)

R = Annual interest rate (as a percentage)

T = Time duration (in years)

In this case, P = $900, R = 8%, and T = 8 years.

Plugging these values into the formula, we get:

Simple Interest = (900 × 8 × 8) / 100 = $576

So, the total amount of money you will pay back is the sum of the principal amount and the interest, which is:

Total amount = Principal + Simple Interest

Total amount = $900 + $576 = $1476

Therefore, you will pay back a total of $1476 over the eight-year period.

Answer:

Left box:  1/2n

Right box = 2n - 22

Step-by-step explanation:

Since we want one-half the number and n represents the unknown number, we have 1/2n on the left-hand side of the equation.

Thus, you want to put 1/2n in box on the left.

Twice the number and 22 less than this is given by:  y: 2n - 22 less than this means we subtract.  Thus, we have 2n - 22 as the numerator on the right hand side of the equation.

Thus, you want to put 2n - 22 in the box on the right.

Number of shirts a department store bought = 200

Cost price of 200 shirts = $5400

Cost price of 1 shirt :

\( =\tt \frac{5400}{200} \)

\(\color{plum} =\tt \$27\)

Thus, the cost price of one shirt = $27

Price at which the department store sold each shirt = $30

Which means :

▪︎Cost price of shirt = $27

▪︎Selling price of shrit = $30

Since selling price is greater than cost price, there was a markup in the price of the shirts.

We know that :

\( \color{hotpink}\tt \: markup \: percentage = \color{plum} \frac{selling \: price - cost \: price}{cost \: price } \times 100\)

Markup percentage in the price of the shirts :

\( = \tt \frac{30 - 27}{27} \times 100\)

\( = \tt \frac{3}{27} \times 100\)

\( = \tt \frac{3 \times 100}{27} \)

\( = \tt \frac{300}{27} \)

\( \color{plum} = \tt11.1 \%\)

Thus, the percentage of markup = \( \tt 11.1 \% \)

John earned $400 interest at a rate of 6% for 3 years. Therefore, the amount of money John originally invested was $2,222.22.

We are able to use the Simple interest formula to resolve this problem:

Simple interest is a simple concept in finance that is used to calculate the interest earned or paid on a essential amount over a positive time period.

Simple interest = (principal x charge x time)

Given that John earned $400 in interest at a price of 6% for three years, we are able to set up the equation as:

400 = (P x 0.06 x 3)

In which P is the principal (the original amount invested).

Simplifying this equation, we get:

400 = 0.18P

Dividing both facets through 0.18, we get:

P = $2,222.22

Thus, John originally invested $2,222.22.

The new digital camera that creates photos that are best printed at 4 inches by 6 inches will minimize.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Since the aspect ratio of 4:6 is closer to that of an 11-inch by 14-inch frame (which is approximately 1:1.5) than the aspect ratio of 3.5:5 (which is approximately 7:10).

By minimizing the difference in aspect ratio between the photo and the frame, you will minimize the loss of the edges of the picture when trying to fit it into the frame.

From the probability distribution for the number of defective items in a random sample, the expected value of X is 2.82.

To calculate the expected value of X, we need to multiply each possible value of X by its corresponding probability and sum them up.

The expected value of X, denoted as E(X) or μ, is calculated using the formula:

E(X) = ∑ (x * p(x))

where x represents each possible value of X and p(x) represents the corresponding probability.

In this case, the probability distribution for X is given as follows:

x: 0 1 2 3 4

p(x): 0.1 0.15 0.13 0.07 0.55

To calculate the expected value, we perform the following calculations:

E(X) = (0 * 0.1) + (1 * 0.15) + (2 * 0.13) + (3 * 0.07) + (4 * 0.55)

E(X) = 0 + 0.15 + 0.26 + 0.21 + 2.2

E(X) = 2.82

The expected value represents the average value or mean of the probability distribution. In this case, it represents the average number of defective items we expect to find in a random sample based on the given probabilities.

He cannot save $5 when he is buying something instead of making it himself.

Step-by-step explanation:

He makes $10 from lawn mowing and spends $5 on Taco Bell. He has $5 left.

If he made is lunch, He would have had $10 dollars.

Andrew's argument is flawed because he is not considering all of the costs and benefits associated with his decision to go to Taco Bell instead of preparing his own meal.

An argument is a collection of claims, the premises of which are provided in support of another statement, the conclusion.

There are a few problems with Andrew's argument.

First, he is assuming that the only cost of preparing his own meal is the price of the ingredients. However, there are also opportunity costs associated with preparing his own meal, such as the time he spends making it and the opportunity to do something else during that time (such as study for his exam).

Second, Andrew is assuming that he would have spent the same amount of money on ingredients as he did on his meal at Taco Bell. However, it is possible that the ingredients he would have used to make his own meal would have cost less than $5, in which case he would not have saved as much money as he thinks.

Finally, Andrew is assuming that he would have spent the same amount of time preparing his own meal as he did going to Taco Bell. However, it is possible that it would have taken him longer to prepare his own meal, in which case the opportunity cost of his time would have been even higher.

Overall, Andrew's argument is flawed because he does not evaluate all of the expenses and advantages of his decision to eat at Taco Bell instead of cooking his own dinner.
