Students at a middle school are divided into 6th, 7th, and 8th grades. A random sample of 15 students from each grade is chosen.
Which sampling method best describes this scenario?
A) simple random sample
B) stratified random sample
C) systematic random sample
D) voluntary response sample
Answer:
B. Stratified random sample is the correct answer
The best sampling method that describes the scenario where students from each grade (6th, 7th, and 8th) are randomly chosen in a sample of 15 students from each grade is B) stratified random sample.
In a stratified random sample, the population is divided into distinct groups or strata based on certain characteristics, and then a random sample is taken from each stratum. In this case, the distinct groups are the different grade levels (6th, 7th, and 8th grades). By randomly selecting 15 students from each grade, we ensure representation from each grade level in the sample.
This method allows for a more accurate representation of each grade level within the sample and can provide valuable insights into the characteristics and experiences of students in each grade.

Ms. Costo isn’t sure she is getting the best price, so she sends Ms. Deele to ask the price of the same car. This time the salesman tells her the price is $17,050. Who is offered the better price? What is the price of the better deal after paying the 6% sales tax?
Answer:
Ms. Costco was offered the best price. It would be $15,900.57 after tax
Step-by-step explanation:
Ms. Costco: $18,795 x .90 =$16,915.50 x .94=$15,900.57

Answer:
It has two numbers per turn. The first is 2 and stays the same the whole time. The second number starts as 5, but every time it hits that number, it increases by 1.
Step-by-step:
As we already know, two starts off the turn, so every number on this turn will increase by 2 (6+2=8.)
Now, for this one, we have five, so for this turn we'll increase it by that much (8+5=13).
However, this number won't stay at 5. Instead, it will increase by 1 every time we hit this turn. Let's continue one:
Turn Two = 13+2=15
Turn 5+1 = 6 = 15+6=21
Turn Two = 21+2=23
Turn 6+1 = 7 = 23+7=31
And from there, the pattern would/will continue!

The ratio of boys to girls in class is 4 : 5
What fraction of the class are boys
Answer:
The ratio of boys to girls is 4:5. So let 4x be the number of boys and 5x be the number of girls. Then 4x+5x = 9x is the total number of students. Then the fraction of boys in the class is 4x/9x = 4/9.

coincident
Answer:
The system of linear equations consist of parallel lines
Step-by-step explanation:
Here, we want to classify the system of linear equations
Firstly, let us write both in the standard forms
For the first;
y = 3x + 2
For the second;
y = 3x-1
The general form of a linear equation is;
y = mx + b
where m is the slope and b is the y-intercept
In both cases, m = 3 and that means the slope is the same
When two lines have same slope values, they are said to be parallel to each other

A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it
sets the price at x dollars, it will sell f(x) = 4,920 - 6x phones. Therefore, the company's revenue is x . (4,920 - 6x). Find
the price x that will maximize the company's revenue.
Answer:
410
Step-by-step explanation:
Revenue is given by the relation :
x . (4,920 - 6x)
F(x) = 4920x - 6x²
To obtain the price, x which maximizes revenue, we take the first derivative of the revenue function and equate to 0
F'(x) = 0
F'(x) = 4920 - 12x
4920 - 12x = 0
-12x = - 4920
x = 4920 / 12
x = 410
Price will be 410

(x + 1/2)^2 + (y- √57)^2 = 81
Step-by-step explanation:
Mathematically, the general equation of a circle is given as;
(x-a)^2 + (y-b)^2 = r^2
where (a,b) represents the circle center and r represents the radius of the circle
Thus, we have this as follows;
(a,b) = (-1/2, √57) , r = 9
Substituting these values;
(x + 1/2)^2 + (y- √57)^2 = 9^2
(x + 1/2)^2 + (y- √57)^2 = 81

Consider the system of equations 3x + y = 10 and 6x – y = 17 . What is the value of the x-coordinate of its solution?
Answer:
x = 3
Step-by-step explanation:
These are simultaneous linear equations hence, we add them because +y and -y will cancel eachother.
3x + y = 10
6x - y = 17
____________
9x = 27
x = 27/9
x = 3
So, x- coordinate is 3
Answer: the answer should be x = 3
