Classify each of the following variables as either categorical or numerical. For those that are numerical, determine whether they are discrete or continuous.
a. Number of students in a class of 35 who turn in a term paper before the due date.
b. Gender of the next baby born at a particular hospital.
c. Amount of fluid (in ounces) dispensed by a machine used to fill bottles with soda pop.
d. Thickness of the gelatin coating of a vitamin E capsule
e. Birth order classification (only child, firstborn, middle child, lastborn) of a math major
Answer:
a. Numerical (discrete).
b. Categorical.
c. Numerical (continuous).
d. Numerical (continuous).
e. Categorical.
Step-by-step explanation:
In Mathematics, a categorical data can be defined as a statistical data type that is used to group informations having the same attributes or characteristics. Some examples of a categorical data are age, gender, race, religion etc.
A numerical data can be defined as a data set that is expressed in numbers only or a data set consisting of numbers rather than words. A numerical data is also known as a quantitative data.
Basically, numerical data are classified into two (2) main categories and these are;
1. Discrete data: a discrete data is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous data: a continuous data is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
a. Number of students in a class of 35 who turn in a term paper before the due date: this is a numerical data and it is discrete in nature because the number of possible values are finite or countable.
b. Gender of the next baby born at a particular hospital: this is a categorical data because it contains a nominal variable (gender).
c. Amount of fluid (in ounces) dispensed by a machine used to fill bottles with soda pop: this is a numerical data and it is continuous in nature because the number of possible values are infinite or uncountable.
d. Thickness of the gelatin coating of a vitamin E capsule: this is a numerical data and it is continuous in nature because the number of possible values are infinite or uncountable.
e. Birth order classification (only child, firstborn, middle child, lastborn) of a math major: this is a categorical data because it is used to categorize an information (birth order).

Step-by-step explanation:
point a is located at coordinates (-4,3) point d is the image of A after a reflection using the y-axis , then a translation two units to the right. what are the coordinates of point d ?
help Asap
Answer:
(6,3)
Step-by-step explanation:
If you reflect (-4,3) over the y-axis it is going to become (4,3).
Then, if you move it 2 units to the right, it becomes (6,3)
The coordinates of the point (-4,3) after reflection and translation will be ( 6, 3 ).
What is translation?The process of changing the location of the image on the coordinate system will be known as the translation.
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the point (-4,3) is the image of A after a reflection using the y-axis, then a translation of two units to the right.
Reflection of point ( -4 , 3 ) ⇒ ( 4 , 3 )
A translation of two units to the right ⇒ ( 4 + 2, 3 ) ⇒ ( 6, 3 )
Therefore, the coordinates of the point (-4,3) after reflection and translation will be ( 6, 3 ).

It costs $520.00 to buy 4 ounces of gold. How much would it cost to buy six tenths of an ounce of gold?
6oz=$780.00
If it costs $520.00 for 4oz you first divide both numbers by 4 which should leave you with 1oz=$130.00 if you then multiply both sides by 6 you end up with your answer 6oz=$780.00

13 people take their driving test on the same day. 9 of them pass. What fraction of people didn’t pass?
Answer:
30.769230769231% or 4/13
Step-by-step explanation:
The fraction of people didn’t pass is 4/ 13.
We have,
Total number of people taking the test: 13
Number of people who passed: 9
So, the number of people who didn't pass
Number of people who didn't pass = Total number of people - Number of people who passed
Number of people who didn't pass = 13 - 9
Number of people who didn't pass = 4
So, the fraction of people didn’t pass
= 4/ 13.

The solutions to the trigonometric equation [tex]cos(\frac{\pi}{4} - x) = \frac{\sqrt{2} }{2} \cdot sin(x)[/tex] are;
{π/2, 3·π/2}
What is a trigonometric equation?A trigonometric equation is an equation involving trigonometric functions with the input of the function, represented by a variable. specified equation is presented as follows;
[tex]cos(\frac{\pi}{4} - x) = \frac{\sqrt{2} }{2} \cdot sin(x)[/tex]
The subtraction formula for the trigonometric ratios of cosine can be presented as follows;
cos(A - B) = cos(A)·cos(B) + sin(A)·sin(B)
Therefore;
cos(π/4 - x) = cos(π/4)·cos(x) + sin(π/4)·sin(x)
sin(π/4) = √2/2
Therefore;
cos(π/4 - x) = cos(π/4)·cos(x) + (√2/2)·sin(x)
cos(π/4 - x) = (√2/2)·sin(x)
cos(π/4)·cos(x) + (√2/2)·sin(x) = (√2/2)·sin(x)
cos(π/4)·cos(x) = (√2/2)·sin(x) - (√2/2)·sin(x) = 0
cos(π/4)·cos(x) = 0
cos(x) = 0/cos(π/4) = 0
x = arccos(0) = π/2 + n·π
Where n is an integer, therefore the values of the angle between 0, and 2·π are;
x = π/2 + π × 0 = π/2 and x = π/2 + 1 × π = 3·π/2
x = π/2 and x = 3·π/2

At 8 A.M. the temperature was-14 °F. By noon, the temperature was 12 °F. How many degrees did it change? *
Answer:
I think that to go to the temperature you you can draw a straight line then on one side write negative the other side positive that the centre write 0 then locate -14 and 12 so negative 14 will fall on the negative side and 12 will fall on the positive side then count from -14 up to positive 12 and you'll find that it changed by 26°

Answer:
b(side length) = 15 centimeters
Step-by-step explanation:
Given an assumed regular rectangular prism which has a height of 18, and volume of 4050 cubic centimeters.
We are also given the formula b = (v/18)^1/2 which is said to find the side length of the rectangular prism. Therefore, it is implied that b must be the side length. Since we know everything except the side length we can substitute the volume since we are already given the height in the formula derived from the problem.
b = (4050/18)^1/2
b = (225)^1/2
b = 15
___________
We should also know that the volume of a rectangular prism is defined as V = l × w × h, with l as the length, w as the width, and h as the height, given that b is the side length which is multiplied by the width and height to get 4050, the base must be a square. Since 4050 = 15 × w × 18
4050 = 270 × w
4050/270 = w
15 = w
w = 15.
A square base is when the length and width are equal. Therefore this value has to be true.
As 15 × 15 × 18 = 4050.
