The money saved by Natalie if, Natalie uses a 15% off coupon when she buys a camera, The original price of the camera is $45.00, is $6.75.
What is percentage?The percentage is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
Given:
Natalie uses a 15% off coupon when she buys a camera, The original price of the camera is $45.00,
Calculate the money saved by Natalie as shown below,
The money saved by the Natalie = 15% of the original price
The money saved by the Natalie = 15 / 100 × 45
The money saved by the Natalie = 0.15 × 45
The money saved by the Natalie = 6.75
Thus, the money saved by Natalie is $6.75.

If sinθ = -1/2 and θ is in Quadrant III, then tanθ = _____.
Answer: [tex]\tan \theta=\dfrac{1}{\sqrt3}.[/tex]
Step-by-step explanation: Given that
[tex]\sin\theta=-\dfrac{1}{2}[/tex] and [tex]\theta[/tex] lies in Quadrant III.
We are to find the value of [tex]\tan \theta.[/tex]
We will be using the following trigonometric identities:
[tex](i)~sin^2\theta+\cos^2\theta=1,\\\\(ii)~\dfrac{\sin\theta}{\cos{\theta}}=\tan \theta.[/tex]
We have
[tex]\tan\theta\\\\\\=\dfrac{\sin\theta}{\cos\theta}\\\\\\=\dfrac{\sin\theta}{\pm\sqrt{1-\sin^2\theta}}\\\\\\=\pm\dfrac{-\frac{1}{2}}{\sqrt{1-\left(\frac{1}{2}\right)^2}}\\\\\\=\pm\dfrac{\frac{1}{2}}{\sqrt{1-\frac{1}{4}}}\\\\\\=\pm\dfrac{\frac{1}{2}}{\frac{\sqrt3}{2}}\\\\\\=\pm\dfrac{1}{\sqrt3}.[/tex]
Since [tex]\theta[/tex] lies in Quadrant III, so tangent will be positive.
Thus,
[tex]\tan \theta=\dfrac{1}{\sqrt3}.[/tex]

A variable is: an instruction for the compiler a location in memory where a value can be stored a description of a value (such as a number or character) none of the above.
Final answer:
A variable is a name assigned to a quantity that can take on various values, and is used by mathematicians, economists, and statisticians in different contexts to represent data or elements of an equation.
Explanation:
A variable is the name given to a quantity that may assume a range of values. Mathematicians and economists often use variables in equations to represent different aspects of a problem or scenario. For example, in the equation of a line, commonly expressed as y = mx + b, the variables are 'x' and 'y'. Here, 'x' typically represents values on the horizontal axis, and 'y' represents values on the vertical axis, while 'b' is the y-intercept, and 'm' is the slope of the line. To understand how an equation with variables functions, we can look at a numerical example.
In statistics, variables can also refer to characteristics or measurements that can be determined for each member of a population. These variables can be numerical or categorical. A numerical variable, such as 'X' representing the number of points earned by a math student, allows for mathematical calculations like averaging. A categorical variable, like 'Y' indicating a person's political party affiliation, places individuals into categories and doesn't lend itself to mathematical operations like averaging.
Which property justifies this statement? If 4x=20, then x=5. Division Property of Equality Reflexive Property of Equality Substitution Property of Equality Subtraction Property of Equality
Answer:
Option 1 - Division Property of Equality
Step-by-step explanation:
Given : If [tex]4x=20[/tex], then x=5.
To find : Which property justifies this statement?
Solution :
The equation is [tex]4x=20[/tex]
To make variable separate we have to remove 4 which is in multiple of variable x.
So, We divide both side by 4,
Applying division property of equality,
We can divide both sides of an equation by the same number and preserve equality.
[tex]\frac{4x}{4}=\frac{20}{4}[/tex]
[tex]x=5[/tex]
Therefore, The property justifies the statement is 'Division Property of Equality'.
So, Option 1 is correct.

John Gray bought a basic car for $32,750.00, with options that cost $375.00. There's a 6% sales tax in his state and a combined $50.00 license and registration fee. What was John's total cost
Answer:
The total cost of the car be $35162.5 .
Step-by-step explanation:
As given
John Gray bought a basic car for $32,750.00, with options that cost $375.00.
Cost of the car = Car cost + Option cost
= $32750 + $375
= $33125
As given
There's a 6% sales tax in his state .
6% is written in the decimal form.
[tex]= \frac{6}{100}[/tex]
= 0.06
Sales tax price = 0.06 × 33125
= $ 1987.5
As given
A combined $50.00 license and registration fee.
Than
Total cost of the car = Cost of the car + Sales tax price + license and registration fee.
= $33125 + $ 1987.5 + $ 50
= $35162.5
Therefore the total cost of the car be $35162.5 .

The Garcias have $12,000 in a saving account. The bank pays 3.5% interest on saving accounts, compounded monthly. Find the balance after 3 years?
To find the balance after 3 years in a savings account with $12,000 and a 3.5% interest rate compounded monthly, we can use the formula for compound interest.
Explanation:To find the balance after 3 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A is the final amountP is the principal amount (initial balance)r is the annual interest rate (as a decimal)n is the number of times interest is compounded per yeart is the number of yearsPlugging in the given values:
P = $12,000r = 0.035n = 12 (monthly compounding)t = 3 yearsThe formula gives us:

Adam earns a base pay plus a commission for each car he sells at Crazy Carl's Cool Cars. His monthly salary is modeled by the function f(c) = 250c + 500. If Adam doesn't sell a car, how much money does he earn for the month?
Answer: 500
Step-by-step explanation:
Since, The monthly salary is modeled by the function,
f(c) = 250 c + 500.
According to the question,
Adam earns a base pay plus a commission for each car he sells at Crazy Carl's Cool Cars.
In the given function c is a variable.
Thus, c must show the number of cars.
Thus, the base pay must be free from any variable.
In the above expression 500 is free from the variable c therefore, 500 is the base pay of Adam.
⇒ f(c) is the total earning by Adam after selling a car.
If he Does not sell any car then c=0,
f(0) = 250×0+500 = 500
Therefore, if he does not sell any car then his earning is 500.

The sum of two right angles always, sometimes, never results in a straight angle. Justify answer
Adding two right angles, each being 90 degrees, always results in a straight angle, which is 180 degrees, so this is always true.
Explanation:The sum of two right angles always results in a straight angle. This can be justified with a basic understanding of angles in a flat plane. A right angle is 90 degrees and a straight angle is 180 degrees. So, if you add two right angles together (90 + 90), you get 180, which is the measure of a straight angle. Hence, this is always true, regardless of the vectors or other elements you are working with. It's also important to note that in broader geometric terms, this statement is also always true: two angles that add up to form a straight line (180 degrees) are referred to as supplementary angles.

Describe how the variability of the x bar distribution changes as the sample size increases
The standard deviation decreases and the sampling distribution becomes more normal as the sample size increases in x bar distribution.
The variability of the x bar distribution changes as the sample size increases. As the sample size increases, the standard deviation of the sampling distribution of the means will decrease, approaching the standard deviation of X. The sampling distribution of the mean becomes more normal as the sample size grows, showing less variability.
