Therefore, 54% of the cupcakes sold that day were chocolate.

A fraction is a way of expressing a quantity that represents a part of a whole. It consists of two numbers separated by a horizontal or diagonal line, where the number on the top is called the numerator and the number on the bottom is called the denominator.

Given by the question.

To find the percentage of cupcakes sold that were chocolate, we need to divide the number of chocolate cupcakes sold by the total number of cupcakes sold and then multiply by 100.

The total number of cupcakes sold is:

162 (chocolate) + 138 (mocha) = 300

The number of chocolate cupcakes sold as a fraction of the total number of cupcakes sold is:

162 / 300 = 0.54

To convert this fraction to a percentage, we multiply by 100:

0.54 x 100 = 54%

To calculate the likelihood of receiving a hand of five clubs, three cards, and one card from each remaining deck,

Five clubs can be obtained in the following ways:

=> C(13,5) = 1,287

where C(n,r) indicates how many different ways r things were combined from a total of n options.

After selecting the five clubs, we must select three cards, one from each of the remaining three decks.

=> C(13,2) * C(3,2) = 702

As a result, there are three cards from each of the other two decks and five clubs, giving rise to the following combinations:

=> C(13,5) * [C(39,3) - C(13,2) * C(3,2)] = 328,664

Finally, there are C(52,8) = 74,837,381 potential hands with 8 cards.

The likelihood of receiving five clubs and three cards, along with one card from each of the other three decks, is as follows:

=> P = 328,664 / 74,837,381

=> P ≈ 0.00439, or about 0.44%.

Step-by-step explanation:

The two values are equal to each other because they are vertically symmetrical (i forgot the term, havent dine this in a while) so 3x-3 = [6(x - 10)] so to simplify this, you could say 6x - 60 = 3x-3, which makes it a lot more understandable. To find x, add 60 to both sides and tou should come out with 6x = 3x + 57, we now subtract 3x from both sides to get 3x = + 57, divide by three then you get the balue of x, which is 19

The balance in the account after 4 years is $3,376.50.

The balance in the account after 25 years is $16,050.07.

The tractor will be worth $9,449.11 after 3 years.

All posted credit and debit transactions are included in your account balance. It's the balance in your account before any pending charges are subtracted. The amount that can be used for withdrawals or purchases is your accessible balance.

1. We can use the formula A = P(1 + r/n) to determine the account balance after 4 years with a $3,000 principal receiving 3% compounding annually (nt)

where A represents the balance, P represents the principal, r represents the yearly interest rate, n represents the number of times interest is compounded annually, and t represents the passage of time in years.

By typing in the indicated values, we get:

A = 3000(1 + 0.03/1)^(1*4)

A = 3000(1.03)^4

A = 3000(1.1255)

A = $3,376.50

Thus, $3,376.50 remains in the account after 4 years.

2. We can once more apply the formula: A = P(1 + r/n) to determine the account balance after 25 years with a $2,000 principal, receiving 7% compounding semi-annually (nt)

Then then, it's a case of the same thing happening again.

By typing in the indicated values, we get:

A = 2000(1 + 0.07/2)^(2*25)

A = 2000(1.035)^50

A = $16,050.07

Thus, the account has a balance of $16,050.07 after 25 years.

3. Considering that the tractor loses 15% of its value per year, we can apply the formula A = P(1 - r)t to determine how much it will be worth after three years.

where A represents the final value, P the starting point, r the depreciation rate, and t the passage of time in years.

By typing in the indicated values, we get:

A = 14340(1 - 0.15)^3

A = 14340(0.85)^3

A = $9,449.11

The tractor will therefore be valued $9,449.11 after three years.

Answer: B 14.0

Step-by-step explanation:

Answer:B.The constant of proportionality is 3. In the table the constant of proportionality is represented by the y-value when the x-value is 1. On a graph, the constant of proportionality represents the steepness of the line.

This is the answer because all of the Y's can be divided by X and equal three.

3 divided by 1 is 3, 15 divided by 5 is 3, 24 divided by 8 is 3, and 27 divided by 9 is 3.

This means that there is a constant rate, which is the proportionality,3.  This is also represented by our first X and Y value. X is 1 and Y is 3, which means that the word length increases by 3.

I hope this helped & Good Luck <3!!!!

Correct answer is B.

So this table represents a set of values related by a constant of proportionality. This constant is just the value of the slope created when the values from the "x" and "y" axis are plotted into a two-dimensional graph.

Using the area formula for the measure for side of square cut out is obtained as 1 inch.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

The length of the cardboard is 12 inch.

The breadth of the cardboard is 10 inch.

Let x inches square be cut from the 4 corners.

Then the length of the base = 12 - 2x.

Then the breadth of the base  = 10 - 2x.

The area of the base is given is 80 inch².

The equation for the carboard will be -

l × b = area

Substitute the values into the equation -

(12 - 2x) × (10 - 2x) = 80

Simplify the equation -

120 - 24x - 20x + 4x² = 80

4x² - 44x + 40 = 0

x² - 11x + 10 = 0

Use the factorization method -

x² - 10x - x + 10 = 0

x(x - 10) - 1(x - 10) = 0

(x - 10)(x - 1) = 0

x = 10 or x = 1

Since, the breadth of the cardboard is 10 inches so x cannot be 10.

Answer:

the sum of a+b+c is 56.

Step-by-step explanation:

If a:b:c = 1:3:4 and c = 28, we can find the values of a and b using the ratios.

Since a:b:c = 1:3:4, we can write:

a = x, b = 3x, c = 4x

where x is some constant of proportionality.

We are given that c = 28, so we can substitute this value to get:

4x = 28

Solving for x, we get:

x = 7

Therefore, a = x = 7 and b = 3x = 21.

The sum of a, b, and c is:

a + b + c = 7 + 21 + 28 = 56

So the sum of a+b+c is 56.

According to the question the 25 hoodies and 20 performance shirts were ordered.

Performance is the result of an individual or organization's efforts in terms of achieving a desired outcome or goal. It is usually measured in terms of objectives, tasks and outcomes, and is a way of assessing the effectiveness of an individual or organization.

Substitution Method:
Let x = the number of hoodies ordered
Let y = the number of performance shirts ordered
Then, x + y = 45  (The total number of items ordered)
60x + 45y = 2400  (The total cost of the order)
Solve for x by substituting y = 45 - x into the second equation:
60x + 45(45 - x) = 2400
60x + 2025 - 45x = 2400
15x = 375
x = 25 (25 hoodies were ordered)
Substitute x = 25 into the first equation:

Answer:

Each student received 40/37 of a pizza slice.

Step-by-step explanation:

To find the fraction of the pizza each student received, we can start by finding the total number of pizza slices. Since each pizza was shared equally among 37 students, we can multiply the number of pizzas (5) by the number of slices in each pizza to get the total number of slices:

Total number of slices = 5 pizzas x 8 slices per pizza = 40 slices

Next, we can divide the total number of slices by the number of students to get the number of slices each student received:

Number of slices per student = 40 slices ÷ 37 students

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1:

Number of slices per student = 40/37 slices

Therefore, each student received 40/37 of a pizza slice.

Hope this helps! I'm sorry if it doesn't. If you need more help, ask me! :]

To find the fraction of the pizza each student received, we need to divide the total number of pizzas by the total number of students:

We can be 95% confident that the true population mean difference between the two samples falls within the range of 0.374 to 0.562

To construct a 95% confidence interval for the data, we need to calculate

The formula for the mean difference is:

x₁ - x₂ = 3.4123 - 2.9442 = 0.4681

The formula for the standard deviation of the differences is:

sD = √[(s₁²/n₁) + (s₂²/n₂)]

SD = √[(1.7458²/57) + (2.0382²/57)]

SD = 0.3555

The margin of error is calculated using the following formula:

ME = t * (sD / √(n))

where t is the critical value for a 95% confidence interval with 56 degrees of freedom

So, we have

ME = 2.003 * (0.3555 / √(57))

ME = 0.0943

Finally, we can calculate the upper and lower bounds of the confidence interval:

CI = (x₁ - x₂) ± ME

CI = 0.4681 ± 0.0943

CI = (0.4681 - 0.0943, 0.4681 + 0.0943)

CI = (0.3738, 0.5624)

Approximate

CI = (0.374, 0.562)
