The matrix that shows the prices in U.S. dollars is:
[1.81 6.32 0.56 0.36]
How to get the matrix in U.S. dollars?Here we have a simple row matrix which can be written as:
[80 280 25 16]
You can see this as a row vector or something like that, notice that if we multiply this by an scalar, we just need to multiply each element by an scalar.
Now, we know that:
1 dollar = 44.32 Nu
then:
1 Nu = (1/44.32) dollars.
So to get the matrix in dollars, just multiply each number by (1/44.32), then we will get:
(1/44.32)*[80 280 25 16] = [80/44.32 280/44.32 25/44.32 16/44.32]
= [1.81 6.32 0.56 0.36]

you are ordering a hamburger and can get up to 6 toppings, but each topping can only be used once. you tell the cashier to surprise you with the toppings you get. what is the probability that you get 0 toppings? express your answer as a fraction or a decimal number rounded to four decimal places.
The probability of getting 0 toppings when ordering a hamburger with a choice of up to 6 toppings is 0.0154, rounded to four decimal places.
The total number of ways to choose 6 toppings out of a possible 6 is given by the combination formula:
[tex]$${ \choose 6} = \frac{6!}{6!(6-6)!} = 1$$[/tex]
This is the total number of possible outcomes.
To get 0 toppings, we need to choose 0 toppings out of 6. The number of ways to do this is:
[tex]{6_{0} =[/tex] [tex]\frac{6!}{0!(6-0)!} = 1$$[/tex]
So the probability of getting 0 toppings is:
[tex]$$P(\text{0 toppings}) =[/tex] [tex]\frac{number of ways to get 0 toppings}{total number of possible outcomes} $$[/tex] [tex]\frac{1}{1} = 1$$[/tex]

the final exam scores in a science class were normally distributed with a mean of 60 and a standard deviation of seven. find the probability that a randomly selected student scored more than 70 on the exam. round your answer to four decimal places.
Answer:
Step-by-step explanation:
We can use the standard normal distribution to solve this problem by standardizing the score.
z = (x - mu) / sigma
Where:
x = 70 (score we are interested in)
mu = 60 (mean score)
sigma = 7 (standard deviation)
z = (70 - 60) / 7 = 1.43
Using a standard normal distribution table or calculator, we can find the probability that z is greater than 1.43. The probability is approximately 0.0764.
Therefore, the probability that a randomly selected student scored more than 70 on the exam is 0.0764 (or about 7.64%).

Explain when each method (graphing,
substitution, and linear combinations) is a good
method to find a solution to a system
of equations.
Method 1: Graphing
Graphing is best when the both equations are shown in slope-intercept form. For example:
[tex]y=\frac{1}{2} x+2\\y=-\frac{1}{2} x+4[/tex]
[tex](2,3)[/tex]
You can easily graph this system of equations and find the intersecting point. The graph is displayed below. This may not always be the case, however and you may get complicated fractions in your answer. In this case, substitution or elimination may be better.
Method 2: Substitution
Substitution is a good method to solve a system of equations when one of the equations can be rearranged to isolate one variable, or the equation already solves for a variable. This isolated expression can then be substituted into the other equation(s) to create a new equation(s) with only one variable.
For example, consider the system of equations:
[tex]y=x-2\\2x-5y=1[/tex]
Since y is much easier to substitute, we can choose y to substitute into the other equation:
[tex]2x-5(x-2)=1[/tex]
We can then simplify the equation:
[tex]2x-5x+10=1\\-3x=-9\\x=3[/tex]
Then you can substitute x into the original equation:
[tex]y=3-2\\y=1[/tex]
Solution: [tex](3,1)[/tex]
Substitution can be a useful method when the system involves two or three variables and one equation can be easily rearranged to isolate a variable. However, it can become more difficult or time-consuming when the system involves more variables or when the equations are not solving for a variable or can be easily solved. In these cases, other methods such as elimination is more efficient.
Method 3: Elimination
Elimination is a good method to solve a system of equations when the equations can be added or subtracted in a way that eliminates one of the variables.
For example, consider the system of equations:
[tex]x+y=90\\x-y=18[/tex]
We can cancel out the variable y and add the other numerals and variables:
[tex]2x=108[/tex]
This simplifies to:
[tex]x=54[/tex]
We can then solve for y:
[tex]54+y=90\\y=36[/tex]
Solution: [tex](54, 36)[/tex]
Once we have the value of x, we can substitute it back into one of the original equations to solve for y.
Although elimination is slightly more complicated, it is the most efficient method out of all of the three methods I have shown here.

Factor 72 + 32. Write your answer in the form a ( b + c) where a is the gcf of 72 and 32
Factor 72 + 32 in the form of a ( b + c) with A having gcf is 72 + 32 is 8(9 + 4).
To factor 72 + 32, we first need to find the greatest common factor (GCF) of 72 and 32.
The prime factorization of 72 is 2³ x 3², and the prime factorization of 32 is 2⁵.
The common factors of 72 and 32 are 1, 2, 4, 8, and 16. The greatest common factor is 8, since it is the largest factor that they both share.
So, we can write 72 + 32 as:
72 + 32 = 8 x (9 + 4)
Therefore, the factored form of 72 + 32 is 8(9 + 4).
To factor 72 + 32, we need to find the greatest common factor (GCF) of 72 and 32, which is 8. We can then use this GCF to write 72 + 32 in factored form as 8(9 + 4). This expression can also be simplified as 8(13), which equals 104. This means that 72 + 32 can be written as the product of 8 and 13, where 8 is the GCF of 72 and 32, and 13 is the sum of the quotients of 72 and 32 when divided by 8. Factoring expressions is an important skill in algebra and is used in many areas of mathematics and science.

andy has 15 coins made up of quarters and half dollars, and their total value is $5.00 how many quarters does he have
Andy has 15 coins made up of quarters and half dollars, and their total value is $5.00.
He has 10 quarters and 5 half dollars.
To find this answer, we can set up the following equation: 0.25Q + 0.50H = 5.00, where Q represents the number of quarters and H represents the number of half dollars. Solving for Q, we get Q = 10. Therefore, Andy has 10 quarters and 5 half dollars.
To solve this equation, we can use algebra to isolate the variable Q. We can start by subtracting 0.50H from both sides, giving us 0.25Q = 5.00 - 0.50H.
Next, we can divide both sides by 0.25, giving us Q = (5.00 - 0.50H) / 0.25. Therefore, we can substitute the values for 5.00 and 0.50H and solve for Q, giving us Q = 10.

the phone calls to a computer software help desk occur at a rate of 3 per minute in the afternoon. compute the probability that the number of calls between 2:00 pm and 2:10 pm is: (a) exactly 25. (b) more than 25.
The probability that the number of phone calls between 2:00 pm and 2:10 pm is exactly 25 is 1/110,592,893.
To calculate this probability, use the Poisson distribution formula: P(x) = (e^-λ * λ^x) / x!, where λ = 3 x 10 = 30. Therefore, P(25) = (e^-30 * 30^25) / 25! = 1/110,592,893.
The probability that the number of phone calls between 2:00 pm and 2:10 pm is more than 25 is the sum of probabilities of all calls more than 25. That is, the probability is 1 - (e^-30 * (30^0 + 30^1 + 30^2 + ... + 30^25)) / (0! + 1! + 2! + ... + 25!).

Write the equation of a circle whose diameter has endpoint (-3,0) and (3,0).
The equation of the circle is with the diameter given is x² + y² = 9.
What is equation of a circle?The standard form of the equation of a circle is (x - h)² + (y - k)² = r², where (h,k) is the center of the circle.
We can quickly determine the circle's centre and radius thanks to this form. We must first square the x and y terms before rearranging the components in order to transform a circular equation into standard form.
The endpoints of the diameter is (-3,0) and (3,0).
Now, using the section formula the coordinates of radius are:
((-3+3)/2, (0+0)/2) = (0,0
The standard form of the equation of a circle is (x - h)² + (y - k)² = r², where (h,k) is the center of the circle.
Substituting the values:
(x - 0)² + (y - 0)² = 3²

about 10% percent of workers (ages 16 years and older) in the united states commute to their jobs by carpooling. you randomly select eight workers. what is the probability that exactly four of them carpool to work?
Probability that exactly four workers carpool to work is 0.214990847, or approximately 21.5%.
We must apply the binomial distribution formula to resolve this issue. The number of successes in a certain number of independent trials that all have the same chance of success are described by the binomial distribution, which is a type of probability distribution. In this scenario, the number of successes is the number of workers who carpool, and the probability of success is 0.1.
The binomial distribution's formula is:
[tex]P(X=k) = to (n pick k) * p*k*1-p (n-k)[/tex]
Where n is the total number of trials (in this case, 8), p is the success probability (0.1), and (n choose k) is the binomial coefficient, which is equal to [tex]n! / (k! * (n-k)![/tex] and P(X=k) is the probability of obtaining exactly k successes.
This formula can be used to determine the likelihood that four employees will carpool to work:

"a number value" is the unknown, so use a variable (letter) I used x, but could be almost any letter (avoid e and i, they have other math meanings)
"10 more than" means to add on 10. You can do that up front or at the end. Order is way more important for subtracting, so no worries here.
"product" means multiplying. So the "product of 2 and a number" is 2x.
So to translate this word phrase into an algebraic expression, you get:

mr. henderson, the principal of blue creek academy, is getting soaked by the splash tank on the last day of school! each time a student hits the target, a 5-quart bucket of water dumps on his head. if 20 students hit the target, how many gallons of water will be dumped on mr. henderson's head?
25 gallons of water will be dumped on Mr. Henderson's head.
To solve the problem, we first need to find the total amount of water dumped on Mr. Henderson's head by all the students. Since each student dumps a 5-quart bucket of water, we can find the total amount by multiplying the number of students by the amount of water per student:
Total amount of water = 20 students x 5 quarts/student = 100 quarts
Next, we convert the total amount of water from quarts to gallons since the problem asks for the answer in gallons. Since 1 gallon equals 4 quarts, we can divide the total amount of water by 4 to get the answer in gallons:
Total amount of water = 100 quarts ÷ 4 quarts/gallon = 25 gallons.

Lewis' Restaurant offers a dinner special that consists of a main dish, a vegetable, a salad, and a roll.
There are 4 main dishes, 7 vegetables, 1 salad, and 1 type of roll to choose from.
To determine the total number of different dinner special combinations that Lewis' offers, you have to multiply the number of options available for each course.
To find the total number of different dinner special combinations offered by Lewis' Restaurant, you have to use the multiplication rule.
The multiplication rule states that if an event can occur in 'a' different ways and another independent event can occur in 'b' different ways,
then the two events can occur in 'a x b' different ways.
Therefore, the total number of different dinner special combinations offered by Lewis' Restaurant can be calculated as follows:
4 main dishes × 7 vegetables × 1 salad × 1 type of roll= 28 different dinner special combinations
Note that we multiply the number of options for each course because the courses are independent.
This means that the choice of the main dish does not affect the choice of the vegetable, salad, or roll, and vice versa. Therefore, we can multiply the number of options for each course to determine the total number of different dinner special combinations that Lewis' Restaurant offers.

A company records the value of a machine used for production at $25,000. As the machine ages, its value depreciates, that is, decreases in value. If the depreciation is estimated to be 20% of the value of the machine at the end of each year, what is the expected value of the machine after 6 years?
The expected value of the machine after 6 years is approximately $4086.
To find the value of the machine after each year, we can use the formula:
Vn = V0 x (1 - r)ⁿ
where Vn is the value of the machine at the end of year n, V0 is the initial value of the machine, r is the depreciation rate (0.20 in this case), and n is the number of years.
For the first year, we have:
V1 = 25000 x (1 - 0.20)¹ = 20000
For the second year, we have:
V2 = 25000 x (1 - 0.20)² = 16000
Continuing this pattern, we find that the value of the machine at the end of the sixth year is:
V6 = 25000 x (1 - 0.20)⁶ = 4085.76

The assessed value of the Weber family’s house is $186,000. The annual property tax is 2. 15% of assessed value. What is the property tax on the Webers home?
the property tax on the Weber family's home is $3,999. To find the property tax on the Weber family's home, we can use the formula:
Property tax = assessed value x tax rate
First, we need to convert the tax rate from a percentage to a decimal. We can do this by dividing the tax rate by 100:
2.15% ÷ 100 = 0.0215
Now we can plug in the values we know into the formula:
Property tax = $186,000 x 0.0215
Property tax = $3,999
So the property tax on the Weber family's home is $3,999.
Property taxes are a common way for local governments to generate revenue to fund public services like schools, roads, and emergency services. The tax rate is usually based on the assessed value of the property, which is determined by a local assessor's office. It's important for homeowners to be aware of the property tax rates in their area so they can budget for this expense. Some homeowners may be eligible for property tax exemptions or reductions, so it's also worth checking with the local assessor's office to see if there are any options available.
