=========================================================
Explanation:
A nominal variable is one where usually a name is attached to it, instead of a number. Something like "mood" is nominal because it takes on the options of "happy", "sad", "angry", etc which are all non-numeric names. We can't do math on them. The same goes for colors, blood type, dog breed, nationality, and month names.
An ordinal variable is one where we can rank the names but we can't exactly do math on them. An example of this would be pain severity (from "no pain" to "in extreme pain") since we can rank and order the pain levels in a natural order. Another example is satisfcation rating, rank in class, and clothing sizes.
A discrete variable is one that takes on finitely many values between two endpoints. Usually (but not always) discrete values are whole numbers. When it comes to counting the number of people or objects, we turn to a discrete variable. With discrete variables, it doesn't make sense to have a midpoint between say 1 and 2 because we cannot have 1.5 of a person.
A continouous variable is one where we can pick any real number in a given interval. Midpoints make sense here now because we can select the midpoint of say 1 and 2 to get 1.5; an example of a continuous variable is someone's height, wind speed, water temperature, or the voltage of electricity.

Find the simple interest Jolie owes on a 2-year loan for $9,500 to buy a used car at the rate of 9% interest.
This is a TWO part question, make sure to answer both part A. and B.
A. Find the amount of interest. Show the math computation use to find the amount of interest.
B. What was the monthly payment? Show the work used to find this answer.
Answers
Answer:
A. Interest = $1710
B. Monthly payment = $467.08
Step-by-step explanation:
Simple interest formula:
[tex]\sf A = P(1+rt)[/tex]
where:
A = final amountP = principalr = annual interest rate (in decimal form)t = time (in years)Given:
P = $9,500r = 9% = 0.09t = 2 yearsSubstitute given information into the formula:
[tex]\begin{aligned} \sf \implies A & = \sf 9500(1+0.09 \cdot 2)\\& = \sf 11210 \end{aligned}[/tex]
Interest = final amount - principal
= 11210 - 9500
= $1710
term = 2 years
1 year = 12 months
⇒ term = 2 × 12 = 24 months
Monthly payment = final amount ÷ months in term
= 11210 ÷ 24
= $467.08
So
[tex]\\ \rm\rightarrowtail I=\dfrac{PRT}{100}[/tex]
[tex]\\ \rm\rightarrowtail I=\dfrac{9500(2)(9)}{100}[/tex]
[tex]\\ \rm\rightarrowtail I=95(18)[/tex]
[tex]\\ \rm\rightarrowtail I=\$ 1710[/tex]
#B
Total months=24
Monthly payment:-
Principle+Interest/months9500+1710/2411210/24467.08≈467$please, any help would be more than great!
3(a-4) ≥ 4 (a+5)
Answers
a (less or equal sign) -32
Interval form:
(-infinity , -32)
Hello there!
In order to solve this inequality, we should first use the distributive property:-
3(a-4)≥4(a+5)
3a-12≥4a+20
Now, add 12 to both sides:-
3a≥4a+32
Subtract 4a from both sides:-
3a-4a≥32
-a≥32
Divide both sides by -1:-
a≤-32
The inequality sign changed because we divided both sides by a negative number.

What is the volume of a right circular cylinder with a diameter of 19.6 yd and a height of 23.52 yd?
Enter your answer in the box. Use 3.14 for pi and round only your final answer to the nearest hundredth.
Answers
Answer:
7092.82 cubic yards
Step-by-step explanation:
The volume of a right circular cylinder is given by:
V represents the volume of a cylinder.
r represents the radius of a cylinder.
h represents the height of a cylinder.
As per the given statement:
Diameter(D) = 19.6 yd and height(h) = 23.52 yd.
Diameter = 2r where r is the radius of the cylinder
Substitute these given values in [1] we have cubic yard
Simplify:
V = 7,092.82291 cubic yard.

Find the perimeter of ΔABC and how you got it.
Answers
Answer:
[tex]\fbox{Perimeter of ∆ABC = 54 units}[/tex]
Step-by-step explanation:
Given:
➳ AC || RP
➳ AC = 18 units
➳ AR = 14 units
➳ RB = 7 units
➳ CP = 10 units
To find:
perimeter of triangle ABC =?
Solution:
in ∆ABC and ∆RBP
since we know AC || RP,
then ∠ACP = ∠RPB
and ∠CAB = ∠PRB (Property of parallel lines)
and ∠B is a common angle in both traingles,
hence ∆ABC ~ ∆RBP from AAA property!
now,
using the properties of similar triangle,
[tex] \frac{AR }{RB} = \frac{CP}{PB} \\ \\ \frac{14}{7} = \frac{10}{PB} \\ \\ X = \frac{10}{2} \\ \\ \fbox{PB = 5} \\ \\ \\ [/tex]
To find perimeter of ∆ABC, add all the components.
Perimeter of ∆ABC = AR + RB + BP +PC + CA
Perimeter of ∆ABC= 14 + 7 +5 +10 + 18 units
[tex]\fbox{Perimeter of ∆ABC = 54 units}[/tex]
Thanks for joining brainly community!
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
In the given figure, PR is parallel to CA, therefore two angles of Triangle ABC is equal to two corresponding angles of Triangle RBP.
that is
[tex]\qquad \sf \dashrightarrow \:\angle BCA = \angle BPR[/tex]
[tex]\qquad \sf \dashrightarrow \:\angle BAC= \angle BRP [/tex]
[ They form pairs of corresponding angles ]
So, we can infer that :
[tex]\qquad \sf \dashrightarrow \:\triangle BAC \sim \triangle BRP [/tex]
The Triangles are similar, by AA criteria ~
let's assume measure of BP = x
Now, let's use its result :
[tex] \qquad \sf \dashrightarrow \:\dfrac{BA}{BR}= \dfrac{BC}{BP}[/tex]
[tex] \qquad \sf \dashrightarrow \:\dfrac{14 + 7}{7}= \dfrac{x + 10 }{x}[/tex]
[tex] \qquad \sf \dashrightarrow \:\dfrac{21}{7}= \dfrac{x + 10 }{x}[/tex]
[tex] \qquad \sf \dashrightarrow \:3= \dfrac{x + 10 }{x}[/tex]
[tex] \qquad \sf \dashrightarrow \:3x={x + 10 }{}[/tex]
[tex] \qquad \sf \dashrightarrow \:3x - {x = 10 }{}[/tex]
[tex]\qquad \sf \dashrightarrow \:2x = 10[/tex]
[tex]\qquad \sf \dashrightarrow \:x = 5 \: \: units[/tex]
So, the required Sides of Triangle ABC are :
AB = 14 + 7 = 21 units AC = 18 units BC = 10 + 5 = 15 unitsTherefore, Perimeter = AB + BC + AC :
[tex]\qquad \sf \dashrightarrow \:21 + 18 + 15[/tex]
[tex]\qquad \sf \dashrightarrow \:54 \: \: units[/tex]

Step-by-step explanation:
When you rotate an object your keeping its congruence the same or keeping the shape the same size, while rotating it around a point, same goes for Translating, with translating, your just moving an image from its starting point, also having it keep the same congruence, but with stretching, you are distorting the shape making it bigger/smaller than the original shape so it looses its congruence making it no longer congruent.

Option C) 301 ft³ is the correct answer.
Hence, the closest to the amount of fuel the cylindrical tank can hold is 301 ft³.
This question is incomplete, the missing image is uplaoded along this answer.
VolumeVolume simply the amount of space enclosed within a container.
The volume of a cylinder can be expressed as;
V = πr²h
Where r is the radius of the base of the cylinder, h is its height and π is pi ( π = 3.14)
Given the data in the question;
Height of the cylinder h = 6ftRadius r = 4ftVolume of the cylinder V = ?To determine the closest to the amount of fuel the tank can hold, we substitute our given values into the expression above.
V = πr²h
V = 3.14 × (4ft)² × 6ft
V = 3.14 × 16ft² × 6ft
V = 301.44ft³
V = 301 ft³
