A principal is ordering pizzas for a school pizza party. He knows that 9 pizzas will feed 25 students. If there are 300 students in the school, how many pizzas will he need to order?
SHOW THE WORK AND HOW YOU GOT THIS ANSWER!!!!
The principal will need to order 108 pizzas to feed 300 students.
We may set up a proportion to determine how many pizzas are required to feed 300 students if 9 pizzas feed 25 students:
25 pupils × 9 pizzas = x pizzas / 300 students
where x is how many pizzas are required to feed 300 kids.
We can cross-multiply and simplify to find x's value:
300 kids times 9 pizzas equals 25 students (x pizzas)
2700 = 25x
x = 2700 / 25
x = 108
In order to serve 300 pupils, the principal will have to order 108 pizzas.

A technology salesperson earned $4008 commission on the sale of video equipment. If he earns 6% on all sales, what amount of video equipment did he sell?
Answer: We can start by using the formula for calculating commission:
Commission = Rate x Sales
where Rate is the commission rate and Sales is the amount of sales.
In this case, we know the commission earned ($4008) and the commission rate (6%), but we don't know the amount of sales. We can set up an equation and solve for Sales:
$4008 = 0.06 x Sales
Dividing both sides by 0.06, we get:
Sales = $4008 ÷ 0.06 = $66,800
Therefore, the salesperson sold $66,800 worth of video equipment.

What are the endpoints of the major axis and minor axis of the ellipse?
(x−2)212+(y+3)236=1
Drag coordinates into the boxes to correctly complete the table.
The correct answer is:
Major Axis Endpoints: (6, -3) and (-2, -3)
Minor Axis Endpoints: (2, 3) and (2, -9).
What is a major axis?The major axis of a graph is the line that divides it in two equal parts. It is also known as the x-axis or the y-axis and it is the axis that is perpendicular to both the x and y axes. The major axis is an important part of the graph because it is used to plot the points on the graph. The points on the graph are plotted in relation to the major axis, allowing for easier interpretation of the graph.
The endpoints of the major axis of an ellipse are the points on the ellipse which are farthest away from each other. These points are located on the longest diameter of the ellipse and are the points at which the ellipse changes directions. Similarly, the endpoints of the minor axis of an ellipse are the points on the ellipse which are closest to each other.
In the equation (x−2)212+(y+3)236=1, the equation describes an ellipse which has its center located at the point (2, -3). The major axis of this ellipse has endpoints located at the points (6, -3) and (-2, -3). The minor axis of this ellipse has endpoints located at the points (2, 3) and (2, -9). Therefore, the correct answer for the table is as follows:
Major Axis Endpoints: (6, -3) and (-2, -3)
Minor Axis Endpoints: (2, 3) and (2, -9)

In a genetics experiment on peas, one sample of offspring contained 439 green peas and 30 yellow peas. Based on those results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the value of
3
4 that was expected?
The result is not reasonably close to the value of 3/4 i.e. 0.75.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The probability of getting a green pea can be estimated by dividing the number of green peas by the total number of peas:
probability of green pea = number of green peas / total number of peas
In this case, the number of green peas is 439 and the total number of peas is the sum of the green and yellow peas, which is:
total number of peas = number of green peas + number of yellow peas
= 439 + 30 = 469
Therefore, the probability of getting a green pea is:
probability of green pea = 439 / 469 ≈ 0.935 or 93.5%
So, the estimated probability of getting an offspring pea that is green is approximately 93.5%.
The result is not reasonably close to the value of 3/4 i.e. 0.75.

Therefore, the area of triangle XYZ is (1/2)bh = (1/2)(15)(15√3) = 225√3. Therefore, the area of triangle XYZ is 225√3.
What is Triangle?Triangle is a three-sided polygon that has three angles and three sides. It is one of the basic shapes in geometry and is a very important concept in mathematics. It is also used in various fields, such as physics and engineering. Triangles can be classified into different types, such as right triangles, isosceles triangles, acute triangles, obtuse triangles, and equilateral triangles. Triangles are also used to form polygons, such as quadrilaterals, pentagons, and hexagons.
To find the area of triangle XYZ, we must first calculate the length of each side of triangle XYZ. The length of each side can be determined by multiplying the length of each side of triangle ABC by five.
Since all three sides of triangle ABC are equal in length, then each side of triangle XYZ will be 5 times the length of triangle ABC. Therefore, the length of each side of triangle XYZ is 5 times the side length of triangle ABC, or 15.
The area of the triangle can be calculated using the Triangle Area formula, A = (1/2)bh, where b is the base of the triangle and h is the height of the triangle. Since we know the length of each side of triangle XYZ, we can use these values to calculate the base and height of the triangle. The base of the triangle is 15, and the height of the triangle is 15√3.
Therefore, the area of triangle XYZ is (1/2)bh = (1/2)(15)(15√3) = 225√3. Therefore, the area of triangle XYZ is 225√3.

A house is purchased at a price of $340,000. The bank requires a 10% down payment. The current mortgage rate is 5.3%. What is the monthly payment for a 30 year mortgage in this scenario? a $1572 b $1826 c $1699 d $1043
The monthly payment for a 30-year mortgage in this scenario is $1,713.78.
What are Percentages?
Percentages are a way of expressing a proportion or ratio in terms of a fraction of 100.
To solve this problem, we can use the formula for calculating the monthly payment for a mortgage:
[tex]M = P[r(1+r)^n/((1+r)^n)-1][/tex]
where M is the monthly payment, P is the principal (the amount borrowed), r is the monthly interest rate, and n is the number of monthly payments (the term of the loan in months).
First, we need to calculate the down payment, which is 10% of the purchase price:
Down payment = 0.1 x $340,000 = $34,000
The principal is the purchase price minus the down payment:
Principal = $340,000 - $34,000 = $306,000
Next, we need to calculate the monthly interest rate. The annual interest rate is 5.3%, so the monthly interest rate is:
r = 0.053/12 = 0.00441667
Finally, we need to calculate the number of monthly payments. A 30-year mortgage has 360 monthly payments (30 years x 12 months per year).
n = 360
Now we can plug in these values into the formula and solve for M:
[tex]M = \$306,000[0.00441667(1+0.00441667)^360/((1+0.00441667)^360)-1][/tex]
M = $1,713.78
Therefore, the monthly payment for a 30-year mortgage in this scenario is $1,713.78.

Which of the sets of side lengths below can be used to build a triangle?
1) 5 cm, 3 cm, and 10 cm (2) 4 cm, 12 cm, and 9 cm (3) 5 cm, 2 cm, and 4 cm (4) 3 cm, 5 cm, and 8 cm
Therefore, sets (2), (3), and (4) can be used to build a triangle, while set (1) cannot.
How are triangles determined by length of sides?Any two sides must add up to more than the third side's length in order to form a triangle. Let's use this principle to compare each pair of side lengths:
5 + 3 = 8 + 10 cm, 3 cm, and 5 cm.
3 + 10 = 13 > 5
5 + 10 = 15 > 3
As the total of the lengths of the two shorter sides is not larger than the length of the longest side, a triangle cannot be constructed with this set of side lengths.
3 measurements: 4 cm, 12 cm, and 9 cm 4 + 12 = 16 > 9 4 + 9 = 13 > 12\s12 + 9 = 21 > 4
Given that the total of any two sides is more than the length of the third side, a triangle can be constructed using this set of side lengths.
3, 2, and 5 centimetres
5 + 2 = 7 > 4
2 + 4 = 6 > 5
5 + 4 = 9 > 2
Given that the total of any two sides is more than the length of the third side, a triangle can be constructed using this set of side lengths.
3, 5, and 8 centimetres
3 + 5 = 8 > 8
3 + 8 = 11 > 5
5 + 8 = 13 > 3
Due to the fact that the sum of any two side lengths is bigger, a triangle can be constructed with this combination of side lengths.

Find the amplitude and period of the function fx=-2sin x .
We can state this by responding to the provided question As a result, the function's amplitude is 2 and its period is.
what is function?Mathematicians research numbers, their variants, equations, associated structures, forms, and possible configurations of these. The word "function" describes the connection between a group of inputs, each of which has a corresponding output. A function is a connection between inputs and outputs where each input results in a single, distinct outcome. Each function has a domain, codomain, or scope assigned to it. Functions are usually denoted by the letter f. (x). An x is entered. On functions, one-to-one capabilities, so multiple capabilities, in capabilities, and on functions are the four main categories of accessible functions.
The sine function of the form f(x) = -2sin(x) is an amplitude-scaled sine function.
The sine function's amplitude is represented by the coefficient, which in this example is -2. Hence, the function's amplitude is 2.
The equation T = 2/, where is the angular frequency, yields the period of the function. The angular frequency of a sine function is given by = 2/T.
With the function f(x) = -2sin(x) substituted, we get:
ω = 2π/T
Sin(x + ) = -2sin(x)
To solve for T, we obtain:
T = 2π/ω = 2π/(-2) = -π
We use T's absolute value as the period cannot be negative, making the function's period T =.
As a result, the function's amplitude is 2 and its period is.

Choose 1 answer:
The mean of the sampling distribution is 606060 and the standard deviation is 871.78.
The central limit theorem is what?As long as the sample size is sufficient (usually, n 30), the central limit theorem implies that if we repeatedly take random samples from a population, the sampling distribution of the sample means will resemble a normal distribution, regardless of the form of the population distribution. This indicates that given the sample mean and standard deviation, we may utilise the normal distribution to draw conclusions about the population mean. Because it enables us to estimate population parameters even when we don't know the population distribution, the central limit theorem is significant.
Given that,
n = 757575
p = 80% = 0.8
q = 1 - 0.8 = 0.2
The mean of the binomial distribution is given as:
Mean: μ = np = (757575)(0.8) = 606060
The standard deviation of the binomial distribution is given as:
σ = √(npq) = √((757575)(0.8)(0.2)) = 871.78

What is probability?
Probability is a way of calculating how likely something is to happen. It is difficult to provide a complete prediction for many events. Using it, we can only forecast the probability, or likelihood, of an event occurring. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.
We know that,
Probability of event = number of favorable outcome/ Total outcome
When a 6 sided dice die twice then

The average speed for the second part of the journey is 100 kilometer per hour.
What is Average Speed?Average Speed is the ratio of the total distance travelled to the total time taken to travel the distance.
Given that,
Distance travelled by motorist in first part = 90 km
Time taken to travel the distance = 1 1/2 hour = 1.5 hours
Distance travelled in second part of the journey = 50 km
Time taken to travel the distance = 1/2 hour = 0.5 hour
Average speed = Distance / Time

23. ECONOMICS In 2000, the demand for nurses was 2,000,000, while the supply was only
1,890,000. The projected demand for nurses in 2020 is 2,810,414, while the supply is
only projected to be 2,001,998.
a. Define the variables, and write equations to represent these situations.
b. Use substitution to determine during which year the supply of nurses was equal to
the demand.
Answer:
Step-by-step explanation:
a. Variables:
D0 = Demand for nurses in 2000 = 2,000,000
S0 = Supply of nurses in 2000 = 1,890,000
D2020 = Projected demand for nurses in 2020 = 2,810,414
S2020 = Projected supply of nurses in 2020 = 2,001,998
Equations:
For 2000: D0 = S0
For 2020: D2020 = S2020
b. Using substitution, we can set the two equations equal to each other:
D0 = S0
2,000,000 = 1,890,000 + m(S0 - 1,890,000) (where m is the rate of increase in supply)
m = 0.063
Now we can use this value of m to find out during which year the supply of nurses was equal to the demand:
2,000,000 = 1,890,000 + 0.063(S - 1,890,000)
S = 2,013,008
Therefore, the supply of nurses was equal to the demand in the year 2013.

A business sets up a sinking fund so they will have a $61,000.00 to pay for a replacement piece of equipment in 9 years when the current equipment will be sold for scrap. If they make deposits at the end of every 2 months for 9 years in the investment that pays 5.9% compounded every 2 months, what size should each payment be?
The every 2 months payments are $
.
Using compound interest, each payment should be $948.86, rounded to two decimal places.
What is compound interest?The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.
When the amount compounds quarterly, it means that the amount compounds 4 times in a year. i.e., n = 4. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:
[tex]A = P (1 + r/4)^t[/tex]
To determine the size of each payment that needs to be made at the end of every 2 months, we can use the formula for the future value of an annuity:
[tex]FV = Pmt x [(1 + r)^{n - 1}] / r[/tex]
When we enter these values into the formula, we obtain:
In this instance, we know that the sinking fund's future value should be $61,000, the interest rate each 2-month period is 5.9%/6 = 0.983%, and there are a total of 54 periods (9 years x 12 months/year / 2 months/period = 54 periods) in the sinking fund's life.
[tex]$61,000 = Pmt x [(1 + 0.00983)^{54 - 1}] / 0.00983[/tex]
Solving for Pmt, we get:
[tex]Pmt = $61,000 x 0.00983 / [(1 + 0.00983)^{54 - 1}][/tex]
= $61,000 x 0.00983 / 0.6346
= $948.86
Therefore, each payment should be $948.86, rounded to two decimal places.
