Diego selling raffle tickets for $1.75 per ticket and she earned for 50 tickets is $87.50.
When a purchase, appropriation, requisition, or direct engagement with the customer occurs at the point of sale, the seller or supplier of the products or services completes a transaction. Title (property or ownership) of the object is transferred, and a price is settled, meaning a price is agreed upon for which the ownership of the item will transfer.
We can calculate how much money Diego would make if he sold each quantity of raffle tickets for $1.75 each using Excel's multiplication function. It is possible to create a table with the number of tickets sold in one column and the money taken in the other.
Diego would receive $17.50, for instance, if he sold 10 tickets (10 x $1.75). If he sold 20 tickets, he would earn $35 (20 x $1.75), and so on. Using Excel's fill handle, you can quickly fill the table with the totals for each sold ticket.
The table would look like this:
Number of Tickets Sold | Amount of Money Earned
•----------------------------------|---------------------------------------•
10 | $17.50
20 | $35.00
30 | $52.50
40 | $70.00
50 | $87.50
By using the multiplication function in Excel, we can quickly calculate the amount of money Diego would earn for any number of raffle tickets sold at $1.75 per ticket.

Solve the quadratic function by factoring x^2 +10x+9-0
The solution for the quadratic function by factoring x^2 +10x+9-0 is x = -1 and x = -9.
Given that the equation is x^2 +10x+9-0.
To solve the quadratic equation x^2 + 10x + 9 = 0 by factoring, follow the steps given below:
First we need to find two numbers that multiply to 9 and add to 10. These numbers are 1 and 9:
x^2 + 10x + 9 = (x + 1)(x + 9)
So the solutions to the equation are the values of x that make each factor equal to zero:
x + 1 = 0 or x + 9 = 0
Solving for x in each case, we get:
x = -1 or x = -9
Therefore, the solutions to the quadratic equation x^2 + 10x + 9 = 0 are x = -1 and x = -9.

a machine in a manufacturing plant has on the average two breakdowns per month. find the probability that during the next three months it has (a) at least five breakdowns, (b) at most eight breakdowns, (c) more than five breakdowns.
The probability that during the next three months it has;
(a) at least five breakdowns is 0.036.(b) at most eight breakdowns is 0.00085.(c) more than five breakdowns is 0.012.Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events.
The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.
The plant has on the average two breakdowns per month,
so the Poisson distribution is,
[tex]P(X=k) = \frac{e^{-\lambda} \lambda^k}{k!}[/tex]
where,
X is the random variable representing the number of events
λ is the average rate at which the events occur
k is the number of events that occur
a) at least five breakdowns
[tex]P(X=k) = \frac{e^{-\lambda} \lambda^k}{k!}[/tex]
P(X =5) = [tex]\frac{e^{-2} 2^5}{5!}[/tex]
= 0.036
Thus, probability that at least five breakdowns in three months is 0.036.
b) at most eight breakdowns
[tex]P(X=k) = \frac{e^{-\lambda} \lambda^k}{k!}[/tex]
[tex]P(X=8) = \frac{e^{-2} 2^8}{8!}[/tex]
= 0.00085.
Therefore, probability of at most eight breakdowns is 0.00085.
c) more than five breakdowns.
[tex]P(X=k) = \frac{e^{-\lambda} \lambda^k}{k!}[/tex]
P(X = 6) = [tex]\frac{e^{-2} 2^6}{6!}[/tex]
=0.012
Therefore, probability of more than five breakdowns is 0.012.

Right tailed area if the confidence interval is 75%
For a 75% confidence interval, the right-tailed area for a 75% confidence interval is 25%.
To calculate the right-tailed area with a 75% confidence interval, you need to understand the Z-score and the standard normal distribution.
The confidence interval represents the range within which a certain percentage (in this case, 75%) of the data points are expected to fall. Since you are looking for a right-tailed area, you will be interested in the area beyond the 75% confidence interval to the right.
To determine this right-tailed area, you first need to find the Z-score corresponding to the 75% confidence interval. Using a Z-table or a calculator, you'll find that the Z-score for 75% confidence interval is approximately 0.674.
Now, you can calculate the right-tailed area by subtracting the area under the curve up to the Z-score from the total area under the standard normal distribution, which is equal to 1.
Right-tailed area = 1 - 0.75 = 0.25 or 25%
So, the right-tailed area for a 75% confidence interval is 25%.

Find the divergence of vector fields at all points where they are defined.
div ( (2x^2 - sin(x2)) i + 5] - (sin(X2)) k)
The divergence of the given vector field at all points where it's defined is div [tex]F = 4x - 2x × cos(x^2).[/tex]
To find the divergence of the given vector field at all points where it's defined, we will use the following terms:
divergence, vector field, and partial derivatives.
The given vector field is[tex]F = (2x^2 - sin(x^2)) i + 5j - sin(x^2) k.[/tex]
To find the divergence of F (div F), we need to take the partial derivatives of each component with respect to their
respective variables and then sum them up. So, div [tex]F = (∂(2x^2 - sin(x^2))/∂x) + (∂5/∂y) + (∂(-sin(x^2))/∂z)[/tex].
Find the partial derivative of the first component with respect to x:

in sales. What amount of commission, in dollars, did she earn?
A) The total commission she earned is $475
B) Total sales for commission of $1375 is $20000
How to calculate the amount of commission?A) Total Commission = Commission 1+ Commission 2
Where:
Commission 1 = 5% of first $5000
Commission 2 = 7.5% of the amount left after $5000 is subtracted
thus
Commission 1 = $5000 * 0.05 = $250
Commission 2= $3000 * 0.075 = $225
Commission total = $250 + $225 = $475
The total commission she earned is $475
B) Total sales = Sales with 5% commission + Sales with 7.5% commission
Sales with 5% commission = $5000
Commission At 7.5% = Total commission -Commission with 5% = $1375 - $250
Sales * 0.075 = $1125
Sales with 7.5% commission = $15000
Total sales = $5000+$15000

show your work and justify your thinking. (6 points)
a. The two equations for the cost of buying groceries and meals are 13f + 4k = 487 and 65+2k = 232
b. The average costs of one fast food meal and of one trip to kroger is $77.33
To calculate the average cost, we divide the total cost by the number of meals or trips. For example, in the first month, the total cost of fast food meals and grocery trips was $487, and there were 13 fast food meals and 4 grocery trips. Therefore, the average cost of a fast food meal can be calculated by dividing the total cost of fast food meals ($487) by the number of fast food meals (13):
Average cost of a fast food meal = $487 / 13 = $37.46
Similarly, we can calculate the average cost of a grocery trip in the first month by dividing the total cost of grocery trips ($487 - total cost of fast food meals) by the number of grocery trips (4):
Average cost of a grocery trip = ($487 - $37.46 x 13) / 4 = $89.38
Using the same method, we can calculate the average cost of a fast food meal and a grocery trip in the second month. In the second month, the total cost of fast food meals and grocery trips was $232, and there were 6 fast food meals and 2 grocery trips. Therefore, the average cost of a fast food meal is:
Average cost of a fast food meal = $232 / 6 = $38.67
And the average cost of a grocery trip is:
Average cost of a grocery trip = ($232 - $38.67 x 6) / 2 = $77.33

Saleem has average of 60 in 4 subjects.Saleem's average drops to 58 after attempting next test.Find grade.
Saleem scored 50 on the next test, and his average dropped to 58.
To find Saleem's grade on the next test, we can use the concept of weighted averages.
Since Saleem has an average of 60 in 4 subjects, we can calculate the total marks he has obtained so far. Let's denote the total marks in the 4 subjects as "T."
Average = Total marks / Number of subjects
60 = T / 4
To find T, multiply both sides by 4:
T = 60 * 4
T = 240
Now, Saleem's total marks after attempting the next test would be (240 + X), where X is the score he gets on the next test.
The new average after attempting the next test is 58.
Average = Total marks / (Number of subjects + 1)
58 = (240 + X) / 5
To find X, first multiply both sides by 5:
58 * 5 = 240 + X
290 = 240 + X
Now, isolate X:
X = 290 - 240
X = 50

The derivative of (f∘g)(x) can be found using the chain rule, which states that the derivative of (f∘g)(x) is (f'(g(x)))(g'(x)).
In this case, (f∘g)(x) = f(g(x)) = 3(5^x) + 3cos(x), so we need to find f'(g(x)) and g'(x) and then multiply them together. The derivative of f(x) is f'(x) = 15^x * ln(5) + 1, so the derivative of f(g(x)) with respect to g(x) is f'(g(x)) = 15^(g(x)) * ln(5) + 1. The derivative of g(x) is g'(x) = -3sin(x). Therefore, using the chain rule, we have:(f∘g)'(x) = f'(g(x)) * g'(x) = (15^(g(x)) * ln(5) + 1) * (-3sin(x))Substituting g(x) = 3cos(x), we get:(f∘g)'(x) = (15^(3cos(x)) * ln(5) + 1) * (-3sin(x))So the correct answer is: (3(5^3cos(x)) ln(5) + 1) * (-3sin(x))
For more similar questions on topic a) The intervals for which f(x) = -5.5sin(x) + 5.5cos(x) is concave up and concave down on [0,2π] can be found by analyzing the second derivative of the function. Taking the second derivative of f(x), we get:
f''(x) = -5.5cos(x) - 5.5sin(x)
To find the intervals of concavity, we need to determine where f''(x) is positive and negative.
When f''(x) > 0, the function is concave up. When f''(x) < 0, the function is concave down.
Setting f''(x) = 0, we get:
-5.5cos(x) - 5.5sin(x) = 0
Simplifying, we get:
cos(x) + sin(x) = 0
Solving for x, we get:
x = 3π/4, 7π/4
These are the possible points of inflection for the function.
Using test intervals, we can determine the intervals of concavity:
When 0 ≤ x < 3π/4 or 7π/4 < x ≤ 2π, f''(x) < 0, so f(x) is concave down.
When 3π/4 < x < 7π/4, f''(x) > 0, so f(x) is concave up.
b) The possible points of inflection for f(x) on [0,2π] are x = 3π/4 and x = 7π/4. To find the coordinates of these points, we can substitute each value of x into the original function f(x):
f(3π/4) = -5.5sin(3π/4) + 5.5cos(3π/4) = 5.5√2 - 5.5√2/2 = 5.5√2/2
So the coordinates of the point of inflection at x = 3π/4 are (3π/4, 5.5√2/2).
Similarly, we can find the coordinates of the point of inflection at x = 7π/4:
f(7π/4) = -5.5sin(7π/4) + 5.5cos(7π/4) = -5.5√2 - 5.5√2/2 = -5.5(3/2)√2
So the coordinates of the point of inflection at x = 7π/4 are (7π/4, -5.5(3/2)√2).

([?], []
The coordinate of the image point is (9,1).
There are eight types of rules for the transformation of a point. When the takes place across a line, then the point (x,y) is changed to the point (y,x).
Given that the rule for the transformation of a point P(1,1) is [tex]R_{x=5} (P)[/tex], which defines the reflection of a point about a line, that is parallel to the y-axis. The line [tex]x=5[/tex] is like a mirror. So, the distance between the line and the image point is equal to the distance between the line and the original point.
Using the point-line distance formula, the distance between the line [tex]x=5[/tex] and a point (1,1) is given by [tex]|5-1|=4[/tex].
Similarly, by the above statement, the distance between the line [tex]x=5[/tex] and the image point will also be 4.
Therefore, the coordinate of the image point is (9,1).

3. (3 points) For ordinary differential equation
X =1- ƛx³6
with ƛ > 0, compute the update Ax= x(t+h) - x(t) using
⚫ Euler's method
⚫ the implicit Euler method
⚫ the midpoint method.
The following are the updates for the given ordinary differential equation using Euler's method, the implicit Euler method, and the midpoint method.
To compute the update Ax for the given ordinary differential equation using Euler's method, we first need to discretize the time domain. Let t0 be the initial time and tn = t0 + nh be the time after n steps of size h. Then, using Euler's method, we have:
xn+1 = xn + hf(xn, tn)
where f(xn, tn) = 1 - ƛxn³/6. Therefore,
Ax = xn+1 - xn = h(1 - ƛxn³/6)
Using the implicit Euler method, we have:
xn+1 = xn + hf(xn+1, tn+1)
where f(xn+1, tn+1) = 1 - ƛxn+1³/6. Solving for xn+1, we get:
xn+1 = (xn + h)/[1 + ƛh/6(xn+1)²]
which is a nonlinear equation that needs to be solved iteratively at each step. Therefore, the update Ax becomes:
Ax = xn+1 - xn
Using the midpoint method, we have:
xn+1 = xn + hf(xn+½h, tn+½h)
where f(xn+½h, tn+½h) = 1 - ƛ(xn+½h)³/6. Therefore,
xn+1 = xn + h(1 - ƛxn³/6 + 3ƛx²n h/4)
and the update Ax becomes:
Ax = xn+1 - xn = h(1 - ƛxn³/6 + 3ƛx²n h/4)
These are the updates for the given ordinary differential equation using Euler's method, the implicit Euler method, and the midpoint method.

It is kinda hard but just try it
Answer:
we 1st can get the weight of rat by
1 rat and 1 cat + 1 dog and rat = 30
2 rat + 1 cat + 1 dog = 30
Then 1 rat and cat measure 24 so
2 rat + 24 =30
2 rat + 24 =30 1 rat = 3 kg
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 10
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 10
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and 1 dog + 1 rat = 20 kg
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and 1 dog + 1 rat = 20 kg 1 dog + 3kg = 20 kg
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and 1 dog + 1 rat = 20 kg 1 dog + 3kg = 20 kg 1 dog = 17kg
so we get the weight of each now we r going to sum them 1 rat + 1 cat + 1 dog = x
1 rat + 1 cat + 1 dog = x 3 kg + 7 kg + 17 kg = x
1 rat + 1 cat + 1 dog = x 3 kg + 7 kg + 17 kg = x 27 kg = x ..... is the mass of 3 of them

Answer:
(n + 3)(n + 2) or n² + 5n + 6------------------
The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n:
n! = n × (n - 2) × (n - 3) × ... × 2 × 1As per above mentioned definition we see that:
(n + 3)! = (n + 3) × (n + 2) × (n + 1)!Hence the quotient of (n + 3)! and (n + 1)! is:
(n + 3)(n + 2) or n² + 5n + 6For thousands of years, gold has been considered one of the Earth's most precious metals. One hundred percent pure gold is 24-karat gold, which is too soft to be made into jewelry. Most gold jewelry is 14-karat gold, approximately 58% gold. If 18 karat-gold is 75% gold and 12-karat gold, how much of each should be used to make a 14-karat gold bracelet weighing 500 grams
The solution is: 14 karat gold is 58.3333...% gold
We have given that;
75% gold and 50% gold and we need to make 200 grams of 58.3333...% gold.
Since, A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
Here, we have,
A) x + y = 200
B) .75x + .50y = ( (14/24) * 200)
We multiply equation B) by -1.3333... and get
B) -x -.6666...y = -155.5555... then adding A)
A) x + y = 200 we get
.3333...y = 44.4444...
y = 133.3333... grams 12 karat gold
x = 66.6666... grams 18 karat gold
Double-Checking the answer
133.3333... * .5 = 66.6666...
66.6666 * .75 = 50.0000...
Hence, Concentration of final solution = (66.6666... + 50) / 200 = 58.3333...% which is 14 karat gold

Which ordered pair could be the y intercept of a function?
Answer:
C) (0,1)
Step-by-step explanation:
What is a y-intercept?
A y-intercept is a value when x=0, so up and down the y-axis of a graph.
Given this, we can see that x must be equal to 0 to have a y-intercept number.
The first option, (1,1), is located in the first quadrant, making this incorrect.
The second option, (1,0) is when y=0, so the point would be on the x-axis, making this also incorrect.
The third option, (0,1), is when x=0, meaning that the point would be on the y-axis, making this the correct option.
Hope this helps! :)
