If there is a ratio of 150 students to 18 teachers what would be the maximum number of students the school can add if it wants to maintain a ratio of student to teachers 20:1?
The maximum number of students the school can add if it wants to maintain a ratio of student to teachers 20 : 1 is 210.
What does a Ratio define?Ratio defines the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
Given that,
Ratio of student to teachers now = 150 : 18
Ratio of student to teachers to maintain = 20 : 1
For 1 teacher , number of students needed = 20
For 18 teachers, number of students needed = 20 × 18 = 360
Present number of students for 18 teachers = 150
Maximum number of students who can be added = 360 - 150 = 210
Hence school can add a maximum of 210 students in order to maintain a ratio of student to teachers 20:1.

The table represents a quadratic function f(x). x f(x) −10 24 −9 17 −8 12 −7 9 −6 8 −5 9 −4 12 If the equation of the function f(x) is written in standard form f(x) = ax2 + bx + c, what is the value of b?
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.

Evaluate 2+8m if m = 4
Answer: 34
Step-by-step explanation:
The first step is if you multiply 8x4 you get 32
And then if you add 32+2 you get 34
According to PEMDAS
P=Parenthesis
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction
Thus, you have to multiply, then add. If not you will get a way off answer. Also, because M comes before A.
Answer:
34
Step-by-step explanation:
To evaluate the expression 2 + 8m when m = 4, we can simply substitute 4 for m in the expression and simplify:
2 + 8m = 2 + 8 * 4
= 2 + 32
= 34
So, when m = 4, the value of the expression 2 + 8m is 34.
The charge is distributed uniformly throughout the volume of an infinitely long solid cylinder of radius R. (a) Show that, at a distance r from the cylinder axis,
E= rhor/ 2ϵ 0 where rho is the volume charge density. (b) Write an expression for E when r>R.
(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 distribution of the number of transactions per day at a certain automated teller machine (ATM ) is approximately normal with a mean of 80 transactions and a standard deviation of 10 transactions. Which of the following represents the parameters of the distribution?
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.

The director of a hospital pharmacy chooses at random 100 people age 60 or older from each of three surrounding counties to ask their opinions of a new prescription drug program.
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.

What are properties of rectangle?
A rectangle is a four-right-angle quadrilateral. It can also be classified as an equiangular quadrilateral because all of its angles are equal; or a parallelogram with a right angle. A square is a rectangle with four equal-length sides.
In a rectangle, opposite sides are equal in length. So, JL is equal to KM.
We have the expressions for the lengths of JN and NM. Using this information and the fact that JKLM is a rectangle, we can set up an equation:
JN + NM = JL + KM
Substituting the given expressions, we get:
(13x - 10) + (5x + 54) = JL + KM
Simplifying the left side, we get:
18x + 44 = JL + KM
But we know that JL = KM, so we can replace both JL and KM with JL:
18x + 44 = 2JL
Now we can solve for JL:
2JL = 18x + 44
JL = (18x + 44)/2
JL = 9x + 22
