Answer:
Quantitative: i) The number of students in the school vis - a - vis the number of classes in the school. In order words, simply number of students per class
ii) The rate of graduation of students.
Categorical:i) Courses being taken by students
ii) Region of country of students.
Step-by-step explanation:
To answer this question effectively, it's important for us to know that a quantitative variable usually has numerical values, and also have units of measure as well while categorical variables simply places each student into a specific category.
Now, the two quantitative variables we will consider are;
i) The number of students in the school vis - a - vis the number of classes in the school. In order words, number of students per class
ii) The rate of graduation of students.
Also, the two categorical variables we will consider are;
i) Courses being taken by students
ii) Region of country of students

What is h-(-5)=2? And how do you solve it?
Answer:
It is an equation, and the answer is [tex]h = -3[/tex]
Step-by-step explanation:
We have a variable that's equal to a term, so this is an equation.
To solve this, we want to isolate h on one side.
[tex]h - (-5) = 2[/tex]
Subtracting a negative is the same thing as adding a positive:
[tex]h + 5 = 2[/tex]
Now we can subtract 5 from both sides to isolate h.
[tex]h + 5 - 5 = 2-5\\\\h = -3[/tex]

3(y+5)=8y
Solving linear equations
Answer:
y = 3
Step-by-step explanation:
To solve this equation, we will use conventional algebraic techniques as illustrated below.
3(y + 5) = 8y Distribute the 3.
3y + 15 = 8y Subtract 3y from both sides.
15 = 5y Rearrange the equation so the variable is on the left.
5y = 15 Divide by 5 on both sides.
y = 3
Answer:
y =3Step-by-step explanation:
[tex]3\left(y+5\right)=8y\\[/tex]
Expand
[tex]\mathrm{Expand\:}3\left(y+5\right):\quad 3y+15\\\\=3y+15=8y[/tex]
Subtract 15 from both sides
[tex]3y+15-15=8y-15[/tex]
Simplify
[tex]3y=8y-15[/tex]
Subtract 8y from both sides
[tex]3y-8y=8y-15-8y[/tex]
Simplify
[tex]-5y=-15[/tex]
Divide both sides by -5

A kid has 8 more quarters than dimes. The total number of coins is 20.
a. 8 quarters 16 dimes
b. 6 dimes and 14 quarters
c. 6 quarters 14 dimes
d. d + (d + 8) = 20
e. 10 quarters and 10 dimes
f. d + 8 = 20
g. 8d = 20
Answer:
b. 6 dimes and 14 quartersd. d + (d + 8) = 20Step-by-step explanation:
If we let d represent the number of dimes, then d+8 represents the number of quarters. The total number of coins is the sum of the numbers of each:
d +(d +8) = 20 . . . . . matches choice d
Collecting terms, we have ...
2d +8 = 20
d +4 = 10 . . . . . divide by 2
d = 6 . . . . . . . . subtract 4
The kid has 6 dimes and 14 quarters. (matches choice b)

a recipe for chocolate chip cookies calls for 1 1/4 cups of flour. if you are making 2 1/3 recipes, how many cups of flour are needed?
Answer:
2 11/12 cups of flour
Step-by-step explanation:

what is the equation of the tangent drawn for f(x)=x-x^2 which is parallel to the line 4x-y-3=0
plssss help me °~°
Answer:
y = 4x + 9/4
Step-by-step explanation:
4x − y − 3 = 0
y = 4x − 3
The slope of the line is 4.
The slope of the tangent line is:
f(x) = x − x²
f'(x) = 1 − 2x
Setting the slope equal to 4:
4 = 1 − 2x
2x = -3
x = -3/2
The point on f(x) is:
f(-3/2) = -3/2 − (-3/2)²
f(-3/2) = -3/2 − 9/4
f(-3/2) = -15/4
Using point-slope form:
y − (-15/4) = 4 (x − (-3/2))
y + 15/4 = 4 (x + 3/2)
y + 15/4 = 4x + 6
y = 4x + 9/4
Solve for x: two thirds plus one third times x equals two times x
Answer: x = 2/5 in fraction form
In decimal form, the answer is x = 0.4
====================================================
Work Shown:
2/3 = two thirds
2/3 + (1/3)x = 2x is the equation you're given
Multiply every term by 3 so that we clear out the fractions
3*(2/3) + 3*(1/3)x = 3*2x
2 + x = 6x
From here, we solve for x
2 + x = 6x
2+x-x = 6x-x .... subtract x from both sides
2 = 5x
5x = 2
5x/5 = 2/5 ... divide both sides by 5
x = 2/5
x = 0.4
The solution of the expression is,
⇒ x = 0.4
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
''Two thirds plus one third times x equals two times x.''
Now, We can simplify as;
⇒ 2/3 + 1/3x = 2x
Solve for x as;
⇒ 2/3 = 2x - 1/3x
⇒ 2/3 = 5x/3
⇒ 2 = 5x
⇒ x = 2/5
⇒ x = 0.4
Thus, The solution of the expression is,
⇒ x = 0.4

Scientists notice two asteroids moving directly toward each other. Right now, they are 20 million kilometers apart, but they are on a collision course. The graph represents their paths and likely collision point, with the origin representing the initial position of asteroid A. What is the point of intersection of the two lines, and what do the x- and y-values of the point of intersection mean?
Answer:
The point of intersection is (6, 8). This indicates that in 6 days, asteroid A and B will collide at a point that is 8 million miles away from asteroid A's current position and 12 million miles away from asteroid B's current position.
Answer:
The point of intersection of the two lines is (6, 8). The x-value means that the two asteroids will collide in 6 days. The y-value means that they will collide 8 million miles away from where asteroid A is now located.

Prime Factor of 84:
84
84 divides by 2 84 = 42 x 2
84 = 2 x 42
42 divides by 2 42 = 21 x 2
42 = 2 x 2 x 21
21 divides by 3 21 = 7 x 3
21 = 2 x 2 x 3 x 7
2, 3, 7 is a prime number, therefore no further factorization is possible = 2 x 2 x 3 x 7
~~~~~~~~~~~~~~~~~~~~~~
Prime Factor of 98:
98
98 divides by 2 98 = 49 x 2
98 = 2 x 49
49 divides by 7 49 = 7 x 7
49 = 2 x 7 x 7
2, 7 is a prime number, therefore no further factorization is possible = 2 x 7 x 7
