Here is a recipe for $$ cupcakes. • Terrance has $$ cup of flour and $$ eggs. • Duri has $$ cups of flour and $$ grams of butter. • Habib has $$ cups of milk and $$ cups of sugar. • Anika has $$ cup of sugar and $$ cups of milk. If each person has enough of all the other ingredients, how many cupcakes could they make on their own?
Duri can make 72 cupcakes on his own and Habib can make 36 cupcakes on her own, assuming they have enough of all the other ingredients.
To determine how many cupcakes each person can make on their own, we need to check if they have enough of all the other ingredients required to make 12 cupcakes.
Terrance has 1 cup of flour and 6 eggs, which is not enough to make 12 cupcakes.
Duri has 12 cups of flour and 1000 grams of butter, which is more than enough to make 12 cupcakes. However, the recipe requires 3/4 cup of sugar, 2 eggs, and 3/4 cup of milk, which we do not know if Duri has enough of.
Habib has 3 cups of milk and 6 cups of sugar, which is enough to make 12 cupcakes.
Anika has 1 cup of sugar and 4 cups of milk, which is not enough to make 12 cupcakes.
Therefore, only Duri and Habib have enough ingredients to make 12 cupcakes on their own.
To determine how many cupcakes they can make, we need to calculate how much of each ingredient is required for one cupcake and then divide the available ingredients by that amount.
For one cupcake, we need:
1/6 cups of flour
1/16 cup of sugar
1/6 eggs
1/16 cups of milk
125/12 grams of butter
Duri has 12 cups of flour and 1000 grams of butter, which is enough to make 72 cupcakes. Habib has 6 cups of sugar and 3 cups of milk, which is enough to make 36 cupcakes.

The line 2x+3y=-22 is tangent to a circle centered at (-1,2) What is the tangent point?
The point of tangency is (-3, -2).
How to find the intersection point?To find the point of tangency , we really want to find the convergence point between the line and the circle. We can begin by tracking down the situation of the circle with focus (- 1,2).
A circle's equation for its center (a,b) and radius (r) is as follows:
[tex](x - a)^2 + (y - b)^2 = r^2[/tex]
Plugging in the values for the center and solving for r, we get:
[tex](x + 1)^2 + (y - 2)^2 = r^2[/tex]
Now we need to find the intersection point between this circle and the line 2x+3y=-22. We can do this by substituting y = (-2/3)x - (22/3) into the equation of the circle:
[tex](x + 1)^2 + ((-2/3)x - (16/3))^2 = r^2[/tex]
Expanding and simplifying, we get:
[tex]10x^2 + 24x + 44 = 9r^2[/tex]
Next, we can make use of the fact that the line intersects the circle at a tangent. This indicates that the distance between the intersection point and the center of the circle is the same as its radius. The distance between the center of the circle and the line can be determined using the distance formula:
distance = [tex]|2x + 3y - (-22)\sqrt{2^2 + 3^2}| = |2x + 3y + 22| \sqrt(13)[/tex]
Setting this equal to the radius r, we get:
[tex]|2x + 3y + 22| \sqrt{13} = \sqrt{10x^2 + 24x + 44} / 3[/tex]
Squaring both sides and simplifying, we get:
[tex]36(2x + 3y + 22)^2 = 13(10x^2 + 24x + 44)[/tex]
Expanding and simplifying, we get:
[tex]26x^2 + 36xy + 45y^2 + 52x + 132y + 240 = 0[/tex]
Now we can use the quadratic formula to solve for x:
x = (-18y - 13 ± [tex]\sqrt{169 - 720y^2[/tex])) / 13
Substituting this into the equation for the line, we get:
2(-18y - 13 ± [tex]\sqrt{169 - 720y^2))[/tex] / 13 + 3y = -22
Simplifying, we get:
y = -2
Substituting y = -2 into the equation for x, we get:
x = -3
Therefore, the point of tangency is (-3, -2).

what is the probability that a simple random sample of 50 ten-gram portions results in a mean of at least 3.6 insect fragments? is this result unusual? what might we conclude?
a) The probability that a simple random sample of 50 ten-gram portions results in a mean of at least 3.6 insect fragments is approximately 0.027.
b) This result is somewhat unusual, as only about 2.7% of samples would be expected to have a mean of at least 3.6 insect fragments. However, it is not necessarily a cause for concern, as it is within the range of expected variation.
c) More information about the distribution of insect fragments in the population and the context in which the samples were collected would be needed to draw more definitive conclusions.
To answer this question, we would need to know the distribution of insect fragments in the population from which the samples are drawn. Let's assume that this distribution is approximately normal with a mean of 3.2 insect fragments and a standard deviation of 0.8 insect fragments, as suggested by FDA guidelines for chocolate.
The distribution of the sample means for samples of size n can be approximated by a normal distribution with mean µ and standard deviation σ/√n. In this case, µ = 3.2 and σ/√n = 0.8/√50 = 0.113.
To find the probability that a sample of 50 ten-gram portions has a mean of at least 3.6 insect fragments, we need to find the area under the normal curve to the right of 3.6. Using a standard normal distribution table or a calculator, we find that this probability is approximately 0.027.
This result is somewhat unusual, as only about 2.7% of samples would be expected to have a mean of at least 3.6 insect fragments. However, it is not necessarily a cause for concern, as it is within the range of expected variation. If the sample mean was much higher, say 4.0 or 4.5, it would be more concerning and warrant further investigation.

Answer: 64 sqaure centimetres.
Step-by-step explanation:
- Surface area means the area of all exterior sides of a 3D dimensional shape. This means we'll have to find the area of every face and then add them all together.
Top and Bottom
4 x 4 = 16
16 x 2 = 32
Both faces are the same so once we find the area of one, we can just double it.
North, South, East and West Side
4 x 2 = 8
8 x 4 = 32
All four remaining faces had the same dimensions, meaning that once you found one, you just had to multiply that answer by 4.
To find the overall surface area add all the areas you have.
32 + 32 = 64
or
16 +_16 + 8 + 8 + 8 + 8 = 64
if a contingency table has nine rows and columns, how many degrees of freedom are there for the test for independence?
There are 64 degrees of freedom for the test for independence in this contingency table.
To find the degrees of freedom for a test for independence in a contingency table, you can use the following formula:
Degrees of freedom (df) = (number of rows - 1) * (number of columns - 1).
In your case, the contingency table has nine rows and nine columns. Using the formula:
df = (9 - 1) * (9 - 1)
df = 8 * 8
df = 64.
In a contingency table, the degrees of freedom (df) for the test of independence are calculated as:
df = (number of rows - 1) x (number of columns - 1)
In this case, the contingency table has nine rows and nine columns, so the degrees of freedom are:
df = (9-1) x (9-1) = 64
This means that there are 64 degrees of freedom for the test of independence.
Degrees of freedom are important because they determine the critical values for the test statistic, which in turn affects the decision to reject or fail to reject the null hypothesis.
In general, as the degrees of freedom increase, the critical values decrease, making it easier to reject the null hypothesis.

In summary, the voltage across each bulb is 13.75V, the resistance of each bulb is 24.55Ω, and the power dissipated in each bulb is 7.7W.
When eight identical lights are connected in series across a 110-V line, the voltage across each bulb will be 110/8 = 13.75 V.
To find the resistance of each bulb, we can use Ohm's law, which states that resistance is equal to voltage divided by current (R = V/I). Therefore, the resistance of each bulb is 13.75/0.56 = 24.55 ohms.
To find the power dissipated in each bulb, we can use the formula P = VI, where P is power, V is voltage, and I is current. Therefore, the power dissipated in each bulb is 13.75 x 0.56 = 7.7 watts.
To find the voltage across each bulb, divide the total voltage by the number of bulbs:
Voltage across each bulb = Total Voltage / Number of Bulbs = 110V / 8 = 13.75V per bulb
Next, use Ohm's Law to find the resistance of each bulb:
Resistance (R) = Voltage (V) / Current (I) = 13.75V / 0.56A = 24.55Ω per bulb
Finally, find the power dissipated in each bulb using the formula:

The compound interest investment earns more interest than the simple interest investment, and the difference becomes more significant over time.
After 10 years, the difference is relatively small, but after 20 years, the compound interest investment has earned over $3,700 more than the simple interest investment.
What are the amounts after 10 and 20 years of the investment?To calculate the amount after 10 and 20 years, we can use the following formulas:
Simple Interest: A = P * (1 + r * t)
Compound Interest: A = P * (1 + r/n)^(n*t)
Where:
A is the amount after t yearsP is the principal amount (the initial investment)r is the annual interest rate (as a decimal)n is the number of times the interest is compounded per yeart is the time in yearsUsing these formulas and the information given in the table, we can calculate the amount after 10 years and 20 years for each type of investment.
For simple interest, the interest is not compounded, so we just add the interest to the principal:
Amount after 10 years: A = $50,000 * (1 + 0.0275 * 10) = $68,750
Amount after 20 years: A = $50,000 * (1 + 0.0275 * 20) = $87,500
For compound interest, we need to use the formula above with n=12 (since the interest is compounded monthly):
Amount after 10 years: A = $50,000 * (1 + 0.0275/12)^(12*10) = $68,704.23
Amount after 20 years: A = $50,000 * (1 + 0.0275/12)^(12*20) = $91,262.47
To compare the two investments, we can look at the difference between the amounts after 10 and 20 years:
Difference after 10 years: $68,750 - $68,704.23 = $45.77
Difference after 20 years: $87,500 - $91,262.47 = $3,762.47

tom can type a report in 3 hours and nelson takes 5 hours. how long will it take the two of them typing together?
It will take Tom and Nelson 1.875 hours, or 1 hour and 52.5 minutes, to complete the report working together.
How to know work done together?To solve this problem, we can use the concept of work done. Let's assume that a report is a unit of work, and Tom and Nelson each do a fraction of the work in one hour.
Tom can do the entire report in 3 hours, which means he can do 1/3 of the report in one hour. Similarly, Nelson can do 1/5 of the report in one hour.
If they work together, the fraction of the report they can do in one hour is the sum of their individual fractions:
1/3 + 1/5 = 8/15
So, together they can do 8/15 of the report in one hour. To find out how long it will take them to do the entire report working together, we can use the formula:
time = work ÷ rate
where work is 1 (the whole report) and rate is 8/15 (the fraction of the report they can do in one hour).
time = 1 ÷ (8/15)
time = 1.875 hours
Therefore, it will take Tom and Nelson 1.875 hours, or 1 hour and 52.5 minutes, to complete the report working together.

⇒ 90 = (86 + 92 + 94 + x) / 4
Multiplying both sides by 4, we get,
⇒360 = 86 + 92 + 94 + x
Simplifying this equation, we get,
⇒ x = 360 - 272
⇒ x = 88
Therefore, Tim needs to get a score of 88 on his fourth quiz in order to have a mean quiz score of exactly 90.

Directions: Find the simplest ratio given a scenario.
1. A designated hitter made 10 hits in 15 games. Find the simplest ratio of hits to games.
The simplest ratio of hits to games is 2:3.
What are proportions?
In mathematics, a proportion is a statement that two ratios are equal. It expresses the relationship between two or more quantities that are directly proportional to each other. A proportion can be represented as an equation of the form:
a/b = c/d
The simplest ratio of hits to games can be found by dividing the number of hits by the number of games:
Hits/Games = 10/15
To simplify this ratio, we can divide both the numerator and denominator by their greatest common factor, which in this case is 5:
Hits/Games = (10/5) / (15/5) = 2/3
Therefore, the simplest ratio of hits to games is 2:3.

f(g(x))
Answer:
To find the values of f(g(x)) for the given values of x, we need to first evaluate g(x) for each value of x, and then plug the result into f(x).
Using the given functions:
g(x) = 2x - 5
f(x) = √(x+1)
Therefore, we have:
f(g(x)) = √(g(x) + 1) = √(2x - 5 + 1) = √(2x - 4) = 2√(x - 2)
So, we can complete the table as follows:
x f(g(x))

In artwork consists of the triangle shown with the shaded triangle is cut out of the larger triangle. What is the area of the remaining unshaded portion?
Thus, the area of unshaded portion for the given values of triangle is found as 48.6 sq. m.
Explain about the triangle:Three sides, three angles, plus three vertices make up a triangle.
A triangle's total internal angles have always been equal to 180 degrees. This is referred to as the triangle's angle sum property.The greatest side of a triangle is the side that faces the largest angle.The sum of the triangle's internal opposite angles is equal to any of its outer angles. This is referred to as the triangle's outside angle property.Area of triangle = 1/2*base *height
Area of unshaded portion = complete area - area of shaded triangle
Area of unshaded portion = 1/2*(20)*(8.1) - 1/2*8*(8.1)
Area of unshaded portion = 81 - 32.4
Area of unshaded portion = 48.6
Thus, the area of unshaded portion for the given values of triangle is found as 48.6 sq. m.

A pre-image has coordinates N(3, -2), A(5, 0) and P(2, 4). The image has coordinates N’ (2, 0), A'(4, 2) and P'(1, 6). Write a transformation rule to describe the path the pre-image made to arrive at the image.
Answer:
f(x + 1) + 2
Step-by-step explanation:
All the points are translated 1 unit to the left and 2 units up.
To write a translation along the x-axis, movement to the right would be written as f(x - a), where a is the amount translated, and movement to the left would be written as f(x + a). In this case, we would need to write the translation as f(x + 1), since it is moving 1 unit to the left.
As for translations along the y-axis, movement upward would be written as f(x) + a, and movement downward would be written as f(x) - a. Thus, the transformation rule to describe the path the pre-image made to arrive at the image would be f(x + 1) + 2.

a bank wishing to increase its customer base advertises that it has the fastest service and that virtually all of its customers are served in less than 11 minutes. a management scientist has studied the service times and concluded that service times are exponentially distributed with a mean of 4.5 minutes. determine what the bank means when it claims 'virtually all' its customers are served in under 11 minutes.
The bank's claim is exaggerated and not entirely accurate.
The bank's claim that virtually all of its customers are served in less than 11 minutes is misleading, as it implies that almost all customers are served in 11 minutes or less. However, based on the given information that service times follow an exponential distribution with a mean of 4.5 minutes, we can calculate the probability that a customer will be served in less than 11 minutes using the cumulative distribution function of the exponential distribution:
P(X < 11) = 1 - [tex]e^{(-11/4.5)[/tex] = 0.956
This means that approximately 95.6% of customers will be served in less than 11 minutes, not "virtually all." Therefore, the bank's claim is exaggerated and not entirely accurate.

Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $35 to come to his house and $50 for every hour they work. If the plumber charges Jerald a total of $190, how many hours did the plumber work?
Write and solve an equation to determine the number of hours worked by the plumber.
After solving equation , the plumber put in 3.1 hours of work (or 3 hours, 6 minutes).
what is equation?A mathematical assertion that demonstrates the equality of two expressions is called an equation The equals symbol (=) is used to denote the separation of two phrases. Numerous mathematical ideas and relationships, including linear functions, quadratic functions, and trigonometric functions, can be represented by equations.
Let's use the letter 'h' to indicate how many hours the plumber put in.
The plumber costs $35 to come to Jerald's residence and $50 for every hour they work. If Jerald is charged a total of $190 by the plumber, the following equation can be written:
$50h + $35 = $190
To solve for 'h,' we obtain:
$50h = $190 - $35
$50h = $155
h = 155 / 50
h = 3.1
Consequently, the plumber put in 3.1 hours of work (or 3 hours, 6 minutes).
