The median of the given data is 78.
What is median?
The median is a measure of central tendency that represents the middle value in a set of data when the data is arranged in order from smallest to largest. It is the value that separates the upper half of the data from the lower half.
To calculate the median, the data must first be ordered. If the data set has an odd number of values, the median is the middle value. If the data set has an even number of values, the median is the average of the two middle values.
The median of the given data can be found by first arranging the data in order from smallest to largest:
3, 5, 78, 81, 90
In this case, there are five values, so the median is the middle value, which is 78.
Therefore, the median of the given data is 78.

Karen and Wayne need to buy a refrigerator because theirs just broke. Unfortunately, their savings account is depleted, and they will need to borrow money in order to buy a new one. Sears offers them an installment loan at 14% (add-on rate). If the refrigerator at Sears costs $1,598 plus 5% sales tax, and Karen and Wayne plan to pay for the refrigerator for 3 years, what is the monthly payment? (Round your answer to the nearest cent.)
Karen and Wayne will need to make monthly payments of $66.39 for 3 years to pay off the loan for their new refrigerator for a given sales tax.
The add-on interest loan formula can be used to determine the monthly payment:
(Loan amount + Interest) / the number of payments equals a payment.
We must first determine the refrigerator's total cost, including sales tax:
Final price is $1,598 plus 5% of $1,598.
$1,677.90 is the total price.
Secondly, we must determine the loan's interest rate:
Interest is calculated as Loan Amount * Addition Rate. Ages in years
Interest equals $702.25 when $1,677.90 multiplied by 0.14 by three.
When interest is included, the total loan amount is:
Loan amount = Purchase price plus interest
Total of the loan: $1,677.90 plus $702.25
Amount borrowed: $2,380.15
In the end, we can figure out the monthly payment:
Payment: ($2,380.15) divided by (3 years * 12 months/year) =
monthly payment of $66.39

The general solution to the differential equation is M = (1/2)n² + Bn, where B is an arbitrary constant.
Describe Differentiation?In calculus, differentiation is a process of finding the rate at which a function changes with respect to its input variable. It is the process of finding the derivative of a function, which represents the slope of the tangent line to the graph of the function at a given point.
The derivative of a function f(x) at a point x=a is denoted as f'(a) and is defined as the limit of the difference quotient as the interval between a and a+h approaches zero, where h is a small nonzero number.
The process of differentiation involves applying differentiation rules or formulas, which are a set of rules that make it easier to find the derivative of various functions. Some of the common rules include the power rule, product rule, quotient rule, and chain rule.
To solve the given differential equation:
[tex]\frac{d^{2}M }{dn^{2} } + 2n\frac{dM}{dn} =n[/tex]
We can assume a solution of the form:
[tex]M= An^{p}[/tex]
where A and p are constants to be determined.
Taking the first derivative of M with respect to n, we get:
[tex]\frac{dM}{dn} = Apn^{p-1}[/tex]
Taking the second derivative of M with respect to n, we get:
[tex]\frac{d^{2}M }{dn^{2} }= A(p)(p-1)n^{p-2}[/tex]
Substituting these expressions into the original differential equation, we get:
[tex]A(p)(p-1)n^{p-2} + 2Apn^{p-1}= n[/tex]
Simplifying, we get:
[tex]A(p)(p-1)n^{p-2} + 2Apn^{p}=n^{p+1}[/tex]
Since this equation must hold for all values of n, we can equate the coefficients of each power of n to get two equations:
A(p)(p-1) = 0
2Ap = 1
From the first equation, we get:
p = 0 or p = 1
If p = 0, then M = A, a constant. Substituting into the differential equation, we get:
0 = n
This is not true for all values of n, so p cannot be 0.
If p = 1, then M = An. Substituting into the differential equation, we get:
2An + 2nA = n
Simplifying, we get:
A = 1/2
Therefore, the solution to the differential equation is:
M = (1/2)n² + Bn
where B is a constant of integration.
Thus, the general solution to the differential equation is:
M = (1/2)n² + Bn
where B is an arbitrary constant.

Several friends each want to buy a ticket to a football game that costs $75.99. To earn money, they worked extra hours at their job where they each earn $9.10 per hour. The table shows the number of hours each person worked each day. Who earned enough money to buy a ticket? What inequality can you write to represent this situation?
Total earnings < Ticket cost, this inequality represents this situation.
What is inequality ?
The inequality, A declaration of relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Equations and questions can both be used to formulate and answer inequality problems.
How to solve inequalities statements?Write two values being compared in the problem in step one. Decide the first value is greater or less than the second value in step two.In step third Insert inequalities symbol between the first and second values if the first value is greater than the second.
We calculate who earned enough money to buy a ticket,than need to calculate the total amount earned by each friend.
For the total amount earned by each friend by multiplying the number of hours worked by hourly rate,
In Friend 1; 5 hours x $9.10 per hour = $45.50
In Friend 2; 4 hours x $9.10 per hour = $36.40
In Friend 3; 7 hours x $9.10 per hour = $63.70
In Friend 4; 3 hours x $9.10 per hour = $27.30
In Friend 5; 6 hours x $9.10 per hour = $54.60
If each friend earned enough money to buy a ticket, than need to compare their total earnings to the cost of a ticket =$75.99. That is, Total earnings ≥ Ticket cost
Now ,substitute their total earnings for each friend,
In,Friend 1; $45.50 ≥ $75.99 that is Not enough money
In Friend 2; $36.40 ≥ $75.99 that is Not enough money
In Friend 3; $63.70 ≥ $75.99 that is Not enough money
In Friend 4; $27.30 ≥ $75.99 that is Not enough money
In Friend 5; $54.60 ≥ $75.99 that is Not enough money
Nobody of friends earned enough money to buy a ticket,

Depreciation expense
The machine's second-year depreciation is $6,660 and the year-end book value under the straight-line method is $65,280.
What is depreciation?The cost of a tangible asset is spread out throughout the course of depreciation. It symbolises the asset's value dropping over time as a result of damage, obsolescence, or other circumstances. Depreciation is crucial because it enables firms to account for an asset's cost over the course of its useful life rather than just in the year it was purchased.
Depreciation can be calculated using a number of different approaches, such as the straight-line method, the decreasing balance method, and the sum-of-years' digits method.
The annual depreciation expense is:
Annual Depreciation Expense = (Cost of Asset - Salvage Value) / Useful Life in Units
Annual Depreciation Expense = ($84,600 - $6,000) / 393,000
Annual Depreciation Expense = $0.20 per unit
For second year we have:
Second-Year Depreciation = Annual Depreciation Expense x Units Produced in Second Year
Second-Year Depreciation = $0.20 x 33,300
Second-Year Depreciation = $6,660
Now, the year-end book value is:
Accumulated Depreciation = Annual Depreciation Expense x Number of Years
Accumulated Depreciation = $0.20 x 2
Accumulated Depreciation = $0.40 per unit
For:
Accumulated Depreciation = $0.40 x 33,300
Accumulated Depreciation = $13,320
Also,
Book Value = Cost of Asset - Accumulated Depreciation - Salvage Value
Book Value = $84,600 - $13,320 - $6,000
Book Value = $65,280
Hence, the machine's second-year depreciation is $6,660 and the year-end book value under the straight-line method is $65,280.

rosa has a limit to the time she may play video games each day she plays for 9 mins on monday which is 30% of the time she can play how many more minutes can rosa play on monday?
According to the calculations we can conclude that Rosa can play 21 more minutes on Monday.
If 9 minutes represents 30% of the time Rosa can play video games, we can use proportional reasoning to find the total time she can play. Let x be the total time she can play in minutes.
9 / x = 30 / 100
We might cross-multiply and simplify to find x's value:
9 * 100 = 30 * x
900 = 30x
x = 900 / 30
x = 30
So Rosa can play a total of 30 minutes each day.
To find how many more minutes she can play on Monday, we subtract the time she has already played from the total time:
30 - 9 = 21
Therefore, Rosa can play 21 more minutes on Monday.

Use a formula to find the surface area of the square pyramid.
3 ft
6 ft
3 ft
The surface area of the square pyramid is 89.4 ft² as the lateral area is 80.4 ft².
How to calculate the surface area of a square pyramid?The surface area of a square pyramid is calculated by the formula
SA = B + 4ℓ, where B is the area of the base and ℓ is the lateral area.
In this case, the base area is 9 square feet (3 ft x 3 ft). The lateral area is 4ℓ, which is calculated by multiplying the slant height by the perimeter of the base.
The slant height of a square pyramid is calculated by the formula
s = √(h² + (a/2)²), where h is the height of the pyramid and a is the length of one side of the base.
In this case, the height is 3 ft and the length of one side of the base is 3 ft. Therefore, the slant height is
s = √(3² + (3/2)²)
= √(9 + 2.25)
= √11.25
= 3.35 ft.
The perimeter of the base is 6 ft (3 ft x 2). Therefore, the lateral area is
4ℓ = 4 x 3.35 ft x 6 ft
= 80.4 ft².
The surface area of the square pyramid is then
SA = B + 4ℓ
= 9 ft² + 80.4 ft²
= 89.4 ft².

Triangle dilation graph 8.
What is dilation?Dilation refers to the process of expanding or stretching an object or a space in one or more directions. In mathematics, dilation is a geometric transformation that changes the size of an object or a figure by either enlarging or reducing its dimensions, while preserving its shape and orientation.
In the context of image processing and computer vision, dilation is an operation that is commonly used to enhance and extract features from images. It involves convolving an image with a small structuring element or kernel, which slides over the image and replaces each pixel with the maximum value within the kernel.
For a dilation with a scale factor of 0.5 and centered at the origin, each coordinate of the triangle will be multiplied by 0.5. Thus:
J(8,0) will become J'(4,0)
L(-2,0) will become L'(-1,0)
K(4,4) will become K'(2,2)
The graph of the original triangle and the image after the dilation are shown below:

Describe Algebra?Algebra is a branch of mathematics that deals with mathematical symbols and the rules for manipulating these symbols. It is a broad area of study that includes a wide range of topics, such as equations, inequalities, functions, polynomials, matrices, and more.
Algebraic expressions are composed of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, division, exponentiation, and logarithms. Equations, on the other hand, are mathematical statements that assert the equality of two algebraic expressions. Inequalities are mathematical statements that assert the relationship between two algebraic expressions using the symbols "<", ">", "<=", or ">=".
Functions in algebra are mappings from one set of numbers to another set of numbers that obey certain rules. These rules may involve properties such as continuity, differentiability, and invertibility.
Jane consumes:
Half a blueberry muffin: 0.5 * 270 = 135 calories
Whole fruit platter: 190 calories
A third of a glass of milk: (1/3) * 102 = 34 calories
So her total calorie intake is: 135 + 190 + 34 = 359 calories (rounded to the nearest whole calorie).
Rob consumes:
Hashbrowns and eggs: 2 * 190 = 380 calories
Half a glass of orange juice: 0.5 * 40 = 20 calories
So his total calorie intake is: 380 + 20 = 400 calories.
