Identify the sampling technique used in the given scenario. The English department is interested in overall performance in its entry-level 101 course. The department chair selects every tenth student's final grade from a list of all students enrolled in the course and calculates the average final grade.
The sampling technique used in the given scenario is Systematic sampling technique.
Systematic sampling technique
Systematic sampling is a probability sampling technique in which researchers randomly choose individuals of a population at regular intervals. The sampling interval, or fixed periodic interval, is calculated by dividing the population size by the required sample size.
Types of Systematic sampling technique
A systematic sample can be generated in three ways:
Systematic random sampling: The most common type of systematic sampling in which the subject is chosen at a predefined interval.
Linear systematic sampling: Instead of picking the sample interval at random, a skip pattern is constructed by following a linear path.
Circular systematic sampling: It occurs when a sample begins from the same spot where it ends.

A construction company in Florida is struggling to sell condominiums. The company believes that it will be able to get an average sale price of $210,000. Let the price of these condominiums in the next quarter be normally distributed with a standard deviation of $15,000. [You may find it useful to reference the z table.]a. What is the probability that the condominium will sell at a price (i) below $200,000? (ii) above $240,000? (Round your final answers to 4 decimal places.)b. The company is also trying to sell an artist’s condo. Potential buyers will find the unusual features of this condo either pleasing or objectionable. The manager expects the average sale price of this condo to be the same as others at $210,000, but with a higher standard deviation of $20,000. What is the probability that this condo will sell at a price (i) Below $200,000? (ii) Above $240,000? (Round your answers to 4 decimal places.)
At a standard deviation of $15,000, the probability that the condominium will sell at a price below $200,000 is 0.2525 and above $240,000 is 0.02. At a standard deviation of $20,000, the probability that the condominium will sell at a price below $200,000 is 0.3085 and above $240,000 is 0.0668.
From the given question;
Let the average sale price(μ)=210,000
Standard Deviation(σ)=$15,000
(a) We have to find the probability that the condominium will sell at a price.
(i) below $200,000, i.e. P(x<200,000)
Z=(x−μ)/σ
Z=(200,000−210,000)/15,000
Z= −10,000/15000
Z= −0.67
Now finding P(x<200,000) is same as finding P(Z<−0.67) using the standard table of z.
P(Z<−0.67) = 0.2525
(ii) above $240,000, i.e. P(x>240,000)
Z=(x−μ)/σ
Z=(240,000−210,000)/15,000
Z= 30,000/15000
Z= 2
Now finding P(x>240,000) is same as finding P(Z>2) using the standard table of z.
P(Z>240,000)=P(Z>2)
P(Z>240,000)=1−P(Z<2)
P(z>240,000)=1−0.98
P(z>240,000)=0.02
(b) Now the average sale price(μ)=210,000
Standard Deviation(σ)=$20,000
We have to find the probability that the condominium will sell at a price.
(i) below $200,000, i.e. P(x<200,000)
Z=(x−μ)/σ
Z=(200,000−210,000)/20,000
Z= −10,000/20000
Z= −0.5
Now finding P(x<200,000) is same as finding P(Z<−0.5) using the standard table of z.
P(Z<−0.5) = 0.2085
(ii) above $240,000, i.e. P(x>240,000)
Z=(x−μ)/σ
Z=(240,000−210,000)/20,000
Z= 30,000/20000
Z= 1.5
Now finding P(x>240,000) is same as finding P(Z>1.5) using the standard table of z.
P(Z>240,000)=P(Z>1.5)
P(Z>240,000)=1−P(Z<1.5)
P(z>240,000)=1−0.93319
P(z>240,000)=0.0668

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Rachel works at 'Best Price Cars' and earns $9 per hour plus 4% commission on every car she sales.
Commission = 9 x 0.04 = $0.36
Commission on 36000 cars = $12960
By working 40 hours he earn = 9 x 40 = $360
Hence, the total income = 360+ 12960 = $13320

Calculate the number of empty chairs per row.
The 600 chairs capacity of the hall and the arrangement such that an increase in the number of rows by 5 decreases the number of chairs per row by 6 is a word problem that indicates;
(a) There are originally 20 rows of chairs in the hall
(b) The number of empty chairs per row is 6 empty chairs
What is a mathematics word problem?A word problem is a question in which the information required to find the solution and the description of the situation is provided using sentences, or regular verbal statements rather that symbols, expressions or operators.
(a) The number of chairs the hall can accommodate = 600
Let x represent the number of rows of chairs, therefore;
The number of chairs per row = 600/x
When the number of rows is increased by and the number of shares per row is decreased by 6, we get;
New number of rows = x + 5
New number of chairs per row = (600/x) -6
The equation for the number of chairs in the hall becomes;
(x + 5) × ((600/x) - 6) = 600
600·x + 6·x² - 570·x - 3000 = 0
6·x² + 30·x - 3000 = 0
x² + 5·x - 500 = 0
(x + 25)·(x - 20) = 0
x = -25 and x = 20
The number of rows is a positive number, therefore;
The original number of rows, x = 20(b) After re-arrangement, the number of rows, x = 20
The new number of chairs per rows = (600/20) - 6 = 24
The new number of rows = 20 + 5 = 25
Let E represent the number of empty chairs, the number of people in each row becomes 24 - E, which indicates;
25 × (24 - E) = 450
450 ÷ 25 = 18 = 24 - E
E = 24 - 18 = 6
The number of empty chairs per row, E = 6

What is linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given two points,
(x1 = 4 ,y1 = -8) and (x2 = 7, y2 = -8)
The equation's general form will be written first:
y = mx + c
We may compute the slope of the equation (m) as follows:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{-8-8}{7-4}[/tex]
m = -16/3
m = -5.33
equation is y = -5.33x + c.
By entering the values of the x and y coordinates, we can now determine the value of the y-intercept (c):
For the point (4,-8),
-8 = -5.33(4) + c
-8 = -21.32 + c
c = 13.32
So the equation become ;
y = -5.33x + 13.32

Answer:
C
Step-by-step explanation:
If we use the distributive property for 4 (2x + 1), we see that 4 (2x) = 8x and that 4 (1) = 1. That means 4 (2x + 1) = 8x + 4 which is not equivalent to 2x + 4y. So this limits our answer to either C or D. C is the correct answer because if we use the distributive property again here for 4 (2x + y), we see that 4 (2x) = 8x and 4 (y) = 4y. That means that 4 (2x + y) = 8x + 4y which is the answer we're looking for.

There are two ways of defining an arithmetic sequence. A "sequence where the differences between each pair of succeeding terms are the same" is what it is. Alternatively, "each term in an arithmetic sequence is obtained by adding a fixed number (positive, negative, or zero) to its preceding term."
The sequence has
n/x+(n+2)
Take n=1 is 1/x+3
Take n=2 is 2/x+4
Take n=3 is 3/x+5
Therefore, The third term of the sequence is 3/x+5 when the arithmetic sequence is 1/x+3, 2/x+4,....

Find the time derivative dp(t)/dt of the x component of the system's total momentum.
The time derivative dp(t)/dt of the x component of the system's total momentum is m₁a₁(t)+m₂a₂(t).
A moving body's motion is measured by its momentum, which is the product of its mass and velocity. The formula for momentum is p=mv. Here, p is momentum, m is mass (in kg), and v is the velocity (m/s).
This equation with respect to time is written as dp(t)/dt. Then, momentum for block 1 is written as,
[tex]\begin{aligned}\frac{dp_1(t)}{dt}&=\frac{d(m_1v_1(t))}{dt}\\&=m_1\frac{dv_1(t)}{dt}\\&=m_1a_1(t)\end{aligned}[/tex]
The momentum for block 2 is written as,
[tex]\begin{aligned}\frac{dp_2(t)}{dt}&=\frac{d(m_2v_2(t))}{dt}\\&=m_2\frac{dv_2(t)}{dt}\\&=m_2a_2(t)\end{aligned}[/tex]
In both equations, the value dv/dt=a with respect to time.
Then, the total momentum is,
[tex]\begin{aligned}\frac{dp(t)}{dt}&=\frac{dp_1(t)}{dt}+\frac{dp_2(t)}{dt}\\&=m_1a_1(t)+m_2a_2(t)\end{aligned}[/tex]
Therefore, the value is m₁a₁(t)+m₂a₂(t).

In this problem, you will analyze a system composed of two blocks, 1 and 2, of respective masses m1 and m2. To simplify the analysis, we will make several assumptions:
The blocks can move in only one dimension, namely, along the x-axis.The masses of the blocks remain constant.The system is closed.At time t, the x components of the velocity and the acceleration of block 1 are denoted by v1(t) and a1(t). Similarly, the x components of the velocity and acceleration of block 2 are denoted by v2(t)and a2(t). In this problem, you will show that the total momentum of the system is not changed by the presence of internal forces.

Need help ASAP.
Answer is not x=-1. 8 or x=0
Answer:
Step-by-step explanation:
x = -9/5 = -1.800 or
x = 0
Help I don't know how to do this
Answer:
Step-by-step explanation:
a(n) = a(1) + (n-1)d
a(n) = -9 + (n-1) x (-6-(-9)
a(n) = -9 + (n-1) x (-6 +9)
a(n)= -9 + (n-1) x 3
a(n) = -9 + 3n - 3
a(n) = 3n - 12
a(30) = 3 x 30 - 12
a(30) = 90 - 12
a(30) = 78

if the mean and mode are 15 and 10, respectively, then determine the potential range of the median for a positively skewed distribution
The median will be greater than 10 and less than 15.
Given,
The mean of the skewed distribution = 15
The mode of the skewed distribution = 10
We have to find the potential range of the median for a positively skewed distribution;
Here,
The empirical relationship between mean, median, and mode for a frequency distribution that is positively skewed is mean > median > mode. Based on this, the range of the median is 15 > median > 10 if the mean is 15 and the mode is 10.
Therefore,
The median will be higher than 10 and lower than 15.
