How many different license plates can be
manufactured for this state?
(Simplify your answer. Type an integer or a fraction.)

Answers

Answer 1

There are 45697600 number of different license plates can be manufactured for this state.

What is Combination?

The combination is a mathematical technique that is the number of ways to arrange the n number of collections where the order of selection does not matter.

ⁿCₐ= n!/(n-a)!a!

Here given in the question is,

On the license plate, there are 4 letters and 2 numbers.

Since, There are 26 alphabets in English from A to Z for which at position 1, there are 26 possibilities of alphabets at every position by,

²⁶C₁ = 26!/(26-1)!1!

       = 26!/25!1!

       = 26!/25!

        = 26

So, for 4 different positions of letters,

Then, The number of ways is,

⇒ 26×26×26×26 = 26⁴= 456976

And, There are 10 numbers in math for which at position 1, there are 10 possibilities of numbers at every position by,

¹⁰C₁ = 10!/(10-1)!1!

       = 10!/9!1!

       = 10!/9!

        = 10

So, for 2 different positions of numbers, the number of ways is,

= 10×10 = 10²= 100

Thus, The total number of ways the license can be manufactured = 456976 × 100= 45697600

Therefore, 45697600 different license plates can be manufactured for this state.

Answers

Quantitative data is data that is measured on a naturally occurring numerical scale.

This can be seen in the data input as 1, 2, 3, 4, which can be meaningfully added, subtracted, multiplied, or divided. Qualitative data, on the other hand, is data that cannot be meaningfully added, subtracted, multiplied, or divided. The data set consisting of classifications AB, C, and D is qualitative because it can only be classified into categories and cannot be meaningfully added, subtracted, multiplied, or divided. To illustrate this further, let’s take an example. If the categories are colours (A = Red, B = Blue, C = Green, and D = Yellow), the data set AB, C, and D cannot be meaningfully added, subtracted, multiplied, or divided, and therefore is qualitative.

Trigonometric Functions are special functions relating to the ratio of the sides of triangles. There are 6 primary ones known as sin, cos, tan, csc, sec, cot which all have definitions relating to the sides of a triangle.

We want to use one where it's defined using the adjacent side and opposite side since we know the adjacent side (the side 6) we just don't know the opposite side (the x side).

Luckily we have a function tan which is defined as: [tex]tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}[/tex]

We can plug in values we know: [tex]tan(60) = \frac{x}{6}[/tex] now just multiply both sides by 6 to solve for the x value: [tex]tan(60) * 6 = x[/tex] and then using a calculator we get approximately: ​10.392 and now from here we can use Pythagorean Theorem:

On a planet far far away from Earth, IQ of the ruling species is normally distributed with a mean of 108 and a standard deviation of 17. Suppose one individual is randomly chosen. Let X = IQ of an individual.

Answers

Answer:

Step-by-step explanation:

Find the probability that X is less than 92:

We can use the cumulative distribution function (CDF) of a normal distribution to find the probability that X is less than 92. The CDF of a normal distribution with mean μ and standard deviation σ is given by:

F(x) = (1/2) * [1 + erf((x-μ)/(σ * sqrt(2)))]

Where erf is the error function.

So, the probability that X is less than 92 can be calculated as:

P(X < 92) = F(92) = (1/2) * [1 + erf((92-108)/(17 * sqrt(2)))]

This value can be calculated using a calculator or statistical software.

Find the probability that X is between 92 and 126:

We can use the CDF to find the probability that X is between 92 and 126. The probability that X is between 92 and 126 is equal to the difference between the CDF values at 126 and 92:

P(92 < X < 126) = F(126) - F(92)

This value can also be calculated using a calculator or statistical software.

Find the IQ of an individual that is in the top 10% of the population:

To find the IQ of an individual that is in the top 10% of the population, we need to find the value of X that corresponds to a cumulative probability of 0.9. This can be done by solving for X in the CDF equation:

F(X) = 0.9

X = μ + σ * inverse_CDF(0.9)

Where inverse_CDF is the inverse cumulative distribution function and can be calculated using a calculator or statistical software. The value of X that corresponds to a cumulative probability of 0.9 is the IQ of an individual that is in the top 10% of the population.

Answers

Marshall's total cost number of calls made after 20 days of telemarketing is 1,430, which is the sum of the sequence of 24 calls made on the first day and 119 calls made on the twentieth day.

Marshall has a goal of making 24 calls on the first day of telemarketing and increasing the number of calls by 5 each day for 20 days. This creates an arithmetic sequence which increases by 5 each day. The formula for the sum of an arithmetic sequence is (n/2) × (a + l), where n is the number of terms in the sequence, a is the first term and l is the last term. In this case, n = 20, a = 24, and l = 119. Plugging these values into the formula yields (20/2) × (24+119)= 1,430. This means that Marshall's total number of calls made after 20 days of telemarketing is 1,430, which is the sum of the sequence of 24 calls made on the first day and 119 calls made on the twentieth day.

Answers

ANSWER -

The volume of one cup can be calculated using the formula for the volume of a cylinder, which is:

V = πr^2h

where r is the radius of the cylinder, which is half of the diameter.

The diameter of the cup is 4.6 inches, so the radius is 2.3 inches. The height of the cup is 7 inches. Using π ≈ 3.14, we can calculate the volume of one cup as:

V = 3.14 x 2.3^2 x 7
= 3.14 x 5.29 x 7
= 116.81 cubic inches

Rounding this to the nearest hundredth, we get 116.27 cubic inches.

To find the total amount of juice that Ramon can pour into 6 cups, we can multiply the volume of one cup by 6:

Total volume = 116.27 x 6
= 697.62 cubic inches

Rounding this to the nearest hundredth, we get 697.65 cubic inches.

what is interest ?

By divided the principal by interest rate, the duration of time, and other factors, simple interest be determined. Simple return means principal plus interest hours straight is the technique used in marketing. The quickest thing to compute interest if to use this method. The most popular way of calculating interest is as portion of the outstanding sum. For example, if he takes $100 from a buddy then agrees to repay the debt at 5% interest, he will only pay his portion of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you need to lend money when you lend it. Typically, interest is determined as an indicator of the overall of the loan total. The loan's interest is the term given to this percentage.

given

A = P(1 + r)ⁿ

A is the sum, P is the sum at the beginning, r is the interest rate, and n is the number of years.

Jo took out a four-month loan from a bank for 3,800. The bank applied a 5.5% discount to the loan.

The true interest rate is going to be

r = 5.5% / 12

r = 0.458%

When this happens, the money the bank gets is equivalent to what Jo paid in interest.

I = P(1 + r)ⁿ - P

I = 3800 (1 + 0.055/12)⁴ - 3800

I = $3870.14 - $3800

What exactly is a function?

A function is defined as a relationship between a group of inputs that each have one output. A function is a connection between inputs in which each input is associated to exactly one output. Every function has a domain and a co-domain, as well as a range. In general, a function is denoted as f(x), where x represents the input. A function's generic representation is y = f(x).

In mathematics, there are several types of functions. Some examples include:

When there is a mapping for a range for each domain between two sets, this is referred to be an injective function or a one to one function.

Surjective functions, also known as Onto functions, are used when more than one element is transferred from domain to range.

Polynomial function: A function made up of polynomials.

Inverse Functions: A function that may be used to inverse another function.

How to order fractions3/10, 4/15, 9/10, 11/15, 17/20

If sorted we first equate the denominator to 60.

18/60, 16/60, 54/60, 44/60, 51/60

So if sorted from smallest to largest, the order becomes:

4/15, 3/10, 11/15, 17/20, 9/10

1/4, 1/3, 2/3, 3/4, 2/5

If sorted we first equate the denominator to 60. it becomes:

15/60, 20/60, 40/60, 45/60, 24/60

So if sorted from smallest to largest, the order becomes:

1/4, 1/3, 2/5, 2/3, 3/4

9/4, 4/3, 5/3, 7/4, 7/5

If sorted we first equate the denominator to 60. it becomes:

135/60, 80/60, 100/60, 105/60, 84/60

So if sorted from smallest to largest, the order becomes:

4/3, 7/5, 5/3, 7/4, 9/4

21/5, 13/6, 25/6, 11/5, 13/10

If sorted we first equate the denominator to 30. it becomes:

126/30, 65/30, 125/30, 66/30, 39/30

So if sorted from smallest to largest, the order becomes:

13/10, 13/6, 11/5, 25/6, 21/5

Should regression analysis be done?The regression analysis (should/should not) be done.

Answers

The correlation coefficient of 1 indicates a strong positive linear relationship between the number of forest fires and the number of acres burned.

However, the correlation coefficient alone does not determine if regression analysis should be done or not. Other factors such as the purpose of the analysis, the distribution of the data, and the presence of outliers should also be considered.

In general, if the relationship between the two variables is of interest and there is sufficient evidence of a linear relationship, then regression analysis may be appropriate. However, a final decision requires a deeper understanding of the problem and the data.

Three girls share an amount of money. the eldest get b/3c of the total amount while the youngest gets b/6c of the total. what fraction does the third girl gets?​

Answers

Answer:

(2c-b) / 2c

Step-by-step explanation:

b/6c + b/3c + y = 1,

Because these are fractions they must add up to 1.

Add and simplify,

(6bc + 3bc)/18c^2

b/2c + y = 1,

Make y the subject,

y = 1 - b/2c

y = (2c-b)/2c

consider the following data sets: variable a: 5 3 5 5 4 8 variable b: 3 1 1 4 2 1 calculate the sample covariance.

Answers

The required sample covariance of the given sample is (C) -0.20.

What is sample covariance?

The link between two random variables from the sample is measured using sample covariance, which uses a smaller sample of the population.

Working with huge populations, such as in long-term medical studies or stock investment tools, makes this statistic helpful.

So, the number of samples is:
n = 6

Then, the mean of x:

[tex]\begin{aligned}\bar{x} & =\frac{\sum x}{n} \\& =\frac{30}{6} \\& =5\end{aligned}[/tex]

The mean of y:
[tex]\begin{aligned}\bar{y} & =\frac{\sum y}{n} \\& =\frac{12}{6} \\& =2\end{aligned}[/tex]

The sample covariance:

[tex]{Cov}(x, y)=\frac{\sum\left(x_i-\bar{x}\right)\left(y_i-\bar{y}\right)}{n-1}\\\begin{aligned}& =\frac{-1}{5} \\& =-0.20\end{aligned}[/tex]

Therefore, the required sample covariance of the given sample is (C) -0.20.
