a computer password must be 5 characters long. the first character must be a capital letter. the second character must be a digit from 0 through 9, inclusive. the third character must be one of eight specified symbols. each of the fourth and fifth characters can be any combination of capital or lowercase letters, digits, or symbols, where the symbols are from the 8 specified symbols. how many different passwords can be made using these rules?

Answers

The total number of different passwords that can be made is 1,084,480.

To find this:

There are 26 capital letters in the English alphabet, so there are 26 possible choices for the first character of the password.

There are 10 digits from 0 through 9, inclusive, so there are 10 possible choices for the second character of the password.

There are 8 specified symbols, so there are 8 possible choices for the third character of the password.

For the fourth and fifth characters, there are a total of 62 possible choices (26 capital letters + 26 lowercase letters + 10 digits + 8 specified symbols).

Therefore, using these rules, the total number of different passwords that can be made is:

26 (possible choices for the first character) x 10 (possible choices for the second character) x 8 (possible choices for the third character) x 62 (possible choices for the fourth and fifth characters) = 1,084,480 different passwords.

Answers

Answer:

Step-by-step explanation:

To find the inverse of a function, we need to switch the variables x and y and solve for the new variable.

Given f(x) = x + 2/3, we can write the inverse as f^-1(y) = x.

So we will replace y with 4 in the inverse function f^-1(y) = x and solve for x.

f^-1(4) = x

x + 2/3 = 4

x = 4 - 2/3

x = 8/3

Therefore, f^-1(4) = 8/3

The median = 1/2(n+1)th term.

1/2(16)th term = 8th term.

The 8th term = 2

The best measure of centre is the mean because the values for the second period has no outliers that might have affected the centre of the distribution.

Determine which numbers in the set are natural numbers, whole numbers, integers, rational numbers, and irrational numbers, Select all that apply.{13, −15, −17/13, √7,3.63, π/4,17}

Answers

Natural Numbers: 13, 17

Whole Numbers: 13, 17

Integers: -15, 13, 17

Rational Numbers: -17/13, 3.63

Irrational Numbers: √7, π/4

First, let us understand what each type of numbers are.

Natural Numbers: All positive numbers from 1 to infinity are considered natural numbers and are therefore a component of the number system. Because they don't contain zero or negative numbers, natural numbers are also known as counting numbers. They are a subset of real numbers, which only include positive integers and exclude negative, zero, fractional, and decimal numbers.

Whole Numbers: The term "whole numbers" refers to numbers devoid of fractions, which are made up of positive integers and zero. Its symbol is "W," and its range of numbers is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,...}. The entire number zero denotes nothing or a null value.

Integers: Positive, negative, and zero are all examples of integers. The Latin word "integer" signifies "whole" or "intact." As a result, fractions and decimals are not included in integers.

Rational and Irrational Numbers: An irrational number cannot be stated using fractions, but a rational number may be expressed as the ratio of two integers with the denominator not equal to zero. Irrational numbers are non-terminating and non-recurring, whereas rational numbers have terminating decimals.

Now, in the set provided, we can classify them as follows.

Natural Numbers: 13, 17

Whole Numbers: 13, 17

Integers: -15, 13, 17

Rational Numbers: -17/13, 3.63

Irrational Numbers: √7, π/4

Thus, this is the final classification.

How to find that a given condition can be modeled by binomial distribution?

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Each of the 800 spins are independent in terms of their result from each other.

Each spin ends up either in shaded region (call it success), or non-shaded region(failure).

P(success) = P(A spin landing in shaded region) = 4/5 (as there are total 5 partition of spinner possible (assuming no other outcome possible), and that there are 4 shaded regions (favorable elementary events).

If we take X = number of successes in those 800 spins, then:

What is exponential function ?

An exponential function is a mathematical function in which the variable, or the input, is in the exponent (power) of the function. It takes the form of f(x) = ab^x, where a and b are constants and x is the variable. The variable x is often time and the constant b is often greater than 1, which causes the function to grow at an increasing rate. It is often used to model growth and decay phenomena, such as population growth, radioactive decay, and others.

To estimate the number of smartphones sold in 2012, we would need to find the exponential function that models the worldwide sales of the smartphone brand from 2008 to 2011. Once we have this function, we can plug in the year 2012 as the input to estimate the number of smartphones sold in that year.

(c) zα ≈ 0.54

To determine zα (also known as the critical value) for a given significance level α, we need to find the z-score that corresponds to the upper α percentage of the standard normal distribution. In other words, we are looking for the z-value that cuts off an area of α in the right tail of the standard normal curve.

The standard normal distribution has a mean (μ) of 0 and a standard deviation (σ) of 1.

To find zα, we can use a standard normal distribution table or a calculator that provides cumulative probability values for the standard normal distribution.

(a) α = 0.0089

For this case, we are looking for the z-score that corresponds to the upper 0.0089 percentage of the standard normal distribution. Using a calculator or standard normal distribution table, we find that zα ≈ 2.33.

(b) α = 0.09

In this case, we need to find the z-score that corresponds to the upper 0.09 percentage of the standard normal distribution. Again, using a calculator or standard normal distribution table, we find that zα ≈ 1.34.

(c) α = 0.707

For α = 0.707, we are interested in the z-score that corresponds to the upper 0.707 percentage of the standard normal distribution. Using a calculator or standard normal distribution table, we find that zα ≈ 0.54.

What is 1/2 as a decimal and percent?

Answers

1/2 as a decimal is 0.5. As a percent, it is 50%. 1/2 can be written as a decimal by dividing the numerator (1) by the denominator (2).

In this case, 1 divided by 2 is 0.5. To convert this decimal to a percent, simply multiply it by 100. 0.5 multiplied by 100 is 50%, so 1/2 as a percent is 50%.

1/2 is 0.5 as a decimal and 50% as a percent.

1/2 is equal to 0.5 when written as a decimal. This means that 1 is divided by 2, resulting in 0.5. To convert this decimal to a percentage, it is necessary to multiply it by 100. When 1/2 is multiplied by 100, it comes out to be 50%, meaning that 1/2 as a percent is 50%. This shows that 1/2 is equal to 0.5 as a decimal and 50% as a percent.

Here to find Rate per week we need to divide the miles by weeks then,

Pavel weekly rate = [tex]\frac{672}{21}[/tex] = 32 miles per week.

Alberto weekly rate = [tex]\frac{420}{12}[/tex] = 35

the congruent sides of an isosceles triangle are each $5$ cm long, and the perimeter is $17$ cm. in centimeters, what is the length of the base?

Answers

The congruent sides of an isosceles triangle are each $5$ cm long, and the perimeter is $17$ cm.  the length of the base is 7 cm.To calculate the length of the base of an isosceles triangle, we can use the formula of the perimeter.

The perimeter is the sum of all sides of a triangle, so the formula is Perimeter = Side1 + Side2 + Base. In this case, the two congruent sides are each 5 cm long, and the perimeter is 17 cm. So, if we set up an equation, we have 17 = 5 + 5 + Base. We can then solve the equation for Base by subtracting 10 from both sides.

This gives us 17 - 10 = 5 + Base, and then subtracting 5 from both sides gives us 12 = Base. Then, we can divide both sides by 12 to get 1 = Base / 12. Lastly, we can multiply both sides by 12 to get 12 = Base. Therefore, the length of the base is 7 cm.

A 95% confidence interval and a 99% confidence interval must be compared.

The confidence level is lower for a 95% confidence interval compared to a 99% confidence interval.

The margin of error would be smaller if the confidence level were lower.

As a result, the 95% confidence interval is smaller than the 99% confidence interval.

Because a 95% interval is narrower, fewer values that could provide the parameter with the correct estimate are included in the interval.

How do you solve an infinite arithmetic sequence?

Answers

We have explained all the steps to solve an infinite arithmetic sequence.

What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term is the sum of the previous term and a constant called the common difference.

When it comes to solving an infinite arithmetic sequence, you can use the following formulas:

The n-th term of an arithmetic sequence can be represented as a+(n-1)d, where "a" is the first term, "d" is a common difference, and "n" is the position of the term in the sequence.

The sum of the first n terms of an arithmetic sequence is represented as S_n = n/2(2a + (n-1)d), where "a" is the first term, "d" is a common difference, and "n" is the number of terms.

If a sequence is infinite, the sum of all terms can be represented as S_inf = a/(1-r) where "a" is the first term and "r" is the common ratio (r=1+d)

If N sweaters can be made from x balls of wool, and the function N(x) = 20x - (10x + n) models the number of sweaters produced where n is a constant. If 500 balls of wool were used to produce 4000 sweaters, what is the value of n?


1)500

2) 1,000

3) 4,000

4) 5,000

15) 10,000

Answers

The value of n in the function is 1000

How to determine the value of n in the model function?

A model function is a way of describing a real-life system or situation using mathematical concepts and language

We have the function N(x) = 20x - (10x + n) models the number of sweaters produced where n is a constant.

Since 500 balls of wool were used to produce 4000 sweaters. To find the value of n, substitute x = 500 and N = 4000 into the function. That is:

N(x) = 20x - (10x + n)

4000 = 20(500) - (10(500) + n)

4000 = 10000 - 5000 - n

4000 = 5000 - n

n = 5000 - 4000

n = 1000

a small town in the us has 5000 football fans. what is the largest possible sample you can take from this town and still be able to calculate the standard deviation of the samling distribution

Answers

The largest possible sample you can take from a population of 5000 football fans and still be able to calculate the standard deviation of the sampling distribution is the entire population, or 5000 people.

The standard deviation of a population is denoted as σ and can be calculated using the formula:

σ = √(Σ(x - μ)^2 / N)

where

x is each individual value in the population

μ is the mean of the population

N is the size of the population. In this case 5000 people.

When it comes to statistics and sampling, the larger the sample size, the more accurate and reliable the results will be. However, in some cases, such as when studying a small population, obtaining a large sample may not be possible.

In the case of a small town with only 5000 football fans, it would be impossible to take a sample larger than the entire population. Therefore, the largest possible sample size would be 5000 and this would allow us to calculate the standard deviation of the sampling distribution, which is a measure of the spread of the data.

This can give us an idea of how much variation there is within the population and how much confidence we can have in the results, but without more information such as the individual values and mean of the population, it is rather impossible to calculate the standard deviation.

Perimeter of one triangle is 20.6 inches.

What is perimeter of triangle?

Perimeter is the length of the boundaries of a closed triangle.

if we add the 3 side lengths of a triangle then the perimeter is determined.

What is the perimeter of one triangle as stated above?

Jane wants to have a rectangular stained glasses that has length 7 inches and width 5 inch.

If she fuses together two triangles of colored glass for obtaining a rectangle, then each triangle will have 3 similar side length.

each triangle has first side length = 5 inches

                              second side length = 7 inches

                   other side length = hypotenuse of right-angled triangle

                       =√(5² + 7²) = √74 inches

A rectangle has four right angles and therefore, the triangles that are developed based on the rectangle must be right-angled.

perimeter of triangle = sum of three side length = (5 + 7+√74) = 20.6 inches
