A company is designing boxes to ship their product to stores. The design team decides that the width of the box should be five feet shorter than the length, and the height of the box should be three feet longer than the width. Due to shipping constraints, the length of the box can be no greater than six feet.
The volume of the box, V(x), can be modeled by a polynomial function, where x is the length of the box. Which of the following correctly models the situation above and gives the correct domain?
The polynomial function is V(x) = x^3 - 7x^2 + 10x and domain of x is (5,6]
Here we are given that the length of the box is x
Also, the width of the box should be 5 feet shorter than the length
Thus, width = x - 5
and the height should be 3 feet longer than the width
Thus, height = x - 5 + 3
= x - 2
Now the volume of the box = length × width × height
Volume = x (x-5) (x-2)
V(x) = (x^2 - 5x) (x-2)
V(x) = x^3 - 2x^2 - 5x^2 + 10x
V(x) = x^3 - 7x^2 + 10x
Now, looking at the options, we see that option C is eliminated.
Now, let us look at the domain of x
Since width cannot be negative (x-5) > 0
⇒ x > 5
Now in option A domain is (0, 6], but x cannot take values from (0,5). Thus, option A is eliminated.
Similarly, we can eliminate option B also since x cannot take values from (0, 2)
Thus, option 4 is the correct answer.

A passbook savings account has a rate of 10%. Find the effective annual yield, rounded to the nearest tenth of a percent, if the interest is compounded monthly.
Effective Annual Yield : 10.5%
Effective Annual Yield
In the case of monthly there are 12 months in a year. Therefore, making n=12. So, the effective annual yield if the interest 10% is compounded monthly is given as r=10, n=12;
[tex]Y= (1 +\frac{r}{n}) ^{n}-1 = (1 +\frac{0.1}{12}) ^{12}-1\\ =(1 +0.00833) ^{12}-1\\ =(1.00833) ^{12}-1\\ = 1.10466 -1\\ = 0.10466[/tex]
But, this is decimal form, to convert it to the percentage form we have to multiply the decimal form by 100 and finally, place "%" after the last digit of the number. That is,
Y= 0.10466× 100%
Y=10.46% or 10.5%

Tony buys CDs at a music store. You get 20% off the price of a CD. You still have to add 5% sales tax. But you find the sales tax after the discount. So you save money on taxes, too." How much money does Tony save by getting the discount before adding the sales tax? Explain by using expressions.
Answer:
Lets say a CD costs a 100 dollars (which it obviosly doesn't)
No matter whether we do the discount before or after tax, it'll end up costing 84 dollars to by the CD.
80% of 100 = 80
80 * 1.05 = 84
80% of 105 = 84

DJI manufactures the Mavic Air 2 quadcopter and offered a 6/4/3 chain discount to primary customers. Drone Nerds is a primary customer and ordered 15 Mavic Air 2's for a total $26,500 list price.
Drone nerds will get 15 Mavic air 2's for $23196.192 after offering a chain discount of 6/4/3.
Chain discount is the series of discounts that are offered from the list price of an object when bought from a store.
A general example of a 10/5 chain discount denotes that there will be a series of discounts on the list price. First a discount of 10% is awarded on the list price then a further 5% on the reduced price.
The List price of the drones is $26500.
Chain discount=6/4/3
So the first discount received is 6% on the $26500.
Price after the first discount=26500- 6%of 26500
Simplifying we get
[tex]=26500-.06\times26500\\=24910[/tex]
The price after the first discount is $24910
Now we will apply the 4% discount on $24910
Price after second discount=24910-4% of 24910
=$23913.60
Now we apply the third discount

Select the action you would use to solve x-4=16 then select property that justifies the action
The value of x is 64 and the property that justifies that action is the multiplication property of equality.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
Mathematical statements are called expressions if they contain at least two terms that are connected by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
As an illustration, the expression x + y is one where x and y are terms with an addition operator in between. There are two types of expressions in mathematics: numerical expressions, which only contain numbers, and algebraic expressions, which also include variables.
We have an expression:
x/4 = 16
Apply Multiplication property of equality:
Multiply by 4 on both sides:
(x/4)4 = 16×4
x = 64

a. Invent two situations that you think would result in distributions with similar measures of variability. Explain your reasoning.
b. Invent two situations that you think would result in distributions with different measures of variability. Explain your reasoning.
Answer:
Step-by-step explanation:
Using measures of variability, it is found that:
a. The situations with constant measures involve constant distributions, such as the number of snow days in Miami each year.
b. The situations with different measures involve constant distributions, such as the number of snow days in Buffalo each year.
What are the measures of variability in a data-set?There are three measures of variability in a data-set: the range, the standard deviation and the variance.
The range is given by the difference between the maximum value and the minimum value of a data-set.
The standard deviation and the variance are described as follows:
The mean of a data-set is given by the sum of all values in the data-set, divided by the number of values.The standard deviation of a data-set is given by the square root of the sum of the differences squared between each observation and the mean, divided by the number of values.The variance is the square of the standard deviation.Uniform(constants) data-sets will have similar measures. One example is the number of snow days in Miami each year, which is always of 0, hence the three measures will be of 0.
More disperse data-set will have different measures. Taking the city of Buffalo, in New York, as an example. On average, it should have 40 days of snow each winter, but on colder winters it can have 60 and warmer winters it can have 20. Hence the distribution with the number of snow days in Buffalo over a period of 20 years will have different range, standard deviation and variances.

A straight line of numbers is shown visually as a number line. This line is used to compare integers on an endless line that extends on both sides, either horizontally or vertically, at equal intervals. On a horizontal number line, the numbers grow as we walk to the right and drop as we move to the left.
A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is said to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers. So, on a number line, we may say that the value of numbers grows as we travel to the right. This indicates that there are more numbers on the right than on the left.
