The mean (μ) and standard deviation (σ) represent the parameters of a normal distribution, so in this case, the parameters of the distribution are: μ = 80 transactions and σ = 10 transactions

A normal distribution, also known as a Gaussian distribution, is a continuous probability distribution that has a bell-shaped curve. This type of distribution is often used to model real-world phenomena that are expected to be distributed in a symmetrical fashion around a central value.

The central value of a normal distribution is the mean (μ), which represents the average of all the observations in the distribution. The spread or dispersion of the distribution is measured by the standard deviation (σ), which indicates how much the observations deviate from the mean.

In the given problem, the distribution of the number of transactions per day at an ATM is assumed to be normal with a mean of 80 transactions and a standard deviation of 10 transactions.

The Equation of line perpendicular to line y = x + 1 and passes through (8,-3) is y= -x+ 5.

A line's  b is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the  change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Equation: y= x+ 11

Now, the slope of perpendicular have the slope equal to negative reciprocal so that the product of slope of perpendicular line is -1.

Then, the slope of perpendicular line is, m= -1.

As, line passes through (8, -3) then the slope intercept form

y= mx+ b

-3 = (-1)(8)+ b

-3 = -8 +b

b= 5

Thus, the Equation of line is y= -x+ 5.

Answer:

55 L of water

Step-by-step explanation:

11-L of 60% acid contains 0.6 × 11 L = 6.6 L acid

Let x = amount of pure water.

Let y = total amount produced of 90% water solution.

A 90% water solution is a 10% acid solution.

Amounts of solutions:

x + 11 = y

Amounts of acid:

6.6 = 0.1y

y = 66

x + 11 = 66

x = 55

Answer: 55 L of water

55 L water has 0 acid.

11 L 60% acid solution has 6.6 L acid.

To choose that a matrix is neither a diagonal matrix and are not scalar multiples of each other. The matrices will be as:

A = [ 2 1 ; 1 2 ]

B = [ -2 1 ; 1 2 ]

The matrices shown above can be used to find invertible matrices. The sum of A and B is [0 2; 2 4], which has a non-zero determinant and is therefore invertible. This choice of A and B satisfies the given conditions because they have different eigenvalues, ensuring they are not scalar multiples of each other, and are also not diagonal matrices.

The key idea behind this choice was to use matrices with the same trace and determinant, which guarantees that their sum will have the same determinant as well. This method allows us to construct examples of invertible matrices that satisfy the given conditions.

In the case of a one-dimensional normal distribution with K classes, the Bayes classifier is not linear but is in fact quadratic.

We begin by noting that the Bayes classifier for the one-dimensional normal distribution is given by:

[tex]h(x) = argmaxk P(Ck|x) = argmaxk P(x|Ck)P(Ck)[/tex]

We can rewrite this as:

[tex]h(x) = argmaxk (1/√2πσk) exp(-1/2σ2k(x-uk)2) P(Ck)[/tex]

We can see that this is a quadratic equation in the form: ax2 + bx + c = 0. We can illustrate this by substituting the values for a, b, and c:

[tex]a = -1/2σ2k[/tex]

b = 0

[tex]c = ln(P(Ck)) - 1/2σ2k u2k[/tex]

We can see that this equation is not linear and is instead quadratic. Therefore, we can conclude that in the case of a one-dimensional normal distribution with K classes, the Bayes classifier is not linear but is in fact quadratic.

Answer:

the value of b is 12.

Step-by-step explanation:

To find the value of b, we can use the vertex form of a quadratic function, which is f(x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Since we know the vertex of this parabola from the table, we can use that information to write the equation in vertex form: f(x) = a(x + 6)^2 + 8

Expanding this, we get f(x) = a(x^2 + 12x + 36) + 8

Comparing this with the standard form, we see that a = 1, b = 12, and c = 8.

Therefore, the value of b is 12.

(a) A distance r from the cylinder axis is pr/2∈₀ and (b) expression for E when r > R is πR²lρ/2πϵ₀

(a) Consider a Gaussian surface in the form of a cylinder with radius r and length A, coaxial with the charged cylinder. An “end view” of the Gaussian surface is shown as a dashed circle. The charge enclosed by it is

q = ρV = πr²lp

V = volume of cylinder

If ρ is positive, the electric field lines are radially outward, normal to the Gaussian surface, and distributed uniformly along with it. Thus, the total flux through the Gaussian cylinder is  Φ = E(2πrl). Now, Gauss’ law leads to :

2π∈₀rlE = πr²lp

E = pr/2∈₀

(b) ) Next, we consider a cylindrical Gaussian surface of radius r > R. If the external field [tex]E_{ext}[/tex] then the flux is  Φ=2πϵ₀[tex]E_{ext}[/tex]

​ The charge enclosed is the total charge in a section of the charged cylinder with length A. That is,  q=πR²lρ. In this case, Gauss’ law yields :

The kind of sample described in the given information is a stratified random sample.

What is stratified random sample ?

A stratified random sample is a type of probability sampling method used to obtain a representative sample of a population by dividing the population into smaller, more homogeneous groups called strata, and then selecting a random sample from each stratum.

This method is used when the population has certain characteristics or subgroups that are of interest to the researcher, and the goal is to ensure that the sample accurately represents each subgroup in proportion to its size in the population.

The process of selecting a stratified random sample involves dividing the population into strata based on some relevant characteristic, such as age, gender, education level, income, or geographic location. Then, a random sample is selected from each stratum, using a simple random sampling method. The sample size from each stratum is proportional to the size of that stratum in the population.

The advantage of a stratified random sample is that it can provide a more accurate representation of the population than other types of sampling methods, as it ensures that each subgroup is adequately represented in the sample.

According to given information :

The population of interest is people age 60 or older from the three surrounding counties. To obtain a representative sample of the population, the director of the hospital pharmacy has divided the population into three strata (i.e., the three surrounding counties) and selected a random sample of 100 people age 60 or older from each stratum. This ensures that the sample includes a proportionate number of participants from each county, which should help to reduce the potential for sampling bias that might result from selecting participants from only one county.

Therefore, this is an example of a stratified random sample.
