grandma famous punch uses a ratio of 5 cups of cranberry juice and 2 cups of sprite. if she needs a total of 56 cups of famous punch how amy cups of cranberry and how many cups of sprite to make 56 cups of punch

Answers

You will need 280 cups of cranberry juice and 56 cups of Sprite to make 56 cups of the famous punch.

What is the ratio definition?

A ratio is a mathematical comparison of two or more values or quantities. It is usually written as a fraction, with the first value or quantity being the numerator and the second value or quantity being the denominator.

To make 56 cups of famous punch using the ratio of 5 cups of cranberry juice to 2 cups of Sprite, you can use the following method:

Write the ratio of cranberry juice to Sprite as a fraction: 5 cups cranberry juice / 2 cups sprite

Multiply the fraction by the desired number of cups of punch: (5 cups cranberry juice / 2 cups sprite) x 56 cups punch

Simplify the equation by cross-multiplying: 5 cups cranberry juice x 56 cups punch = 2 cups sprite x 56 cups punch

Solve for the number of cups of cranberry juice: 5 cups cranberry juice x 56 cups punch = 280 cups of cranberry juice

To find the amount of Sprite use the ratio 5:2, meaning you have to use 2 cups of sprite for every 5 cups of cranberry juice. So use 280/5*2 = 56 cups of sprite

Hence, you will need 280 cups of cranberry juice and 56 cups of Sprite to make 56 cups of the famous punch.

A physical therapist claims that 75% of people lose their balance if they close their eyes while standing on one foot. A gymnast feels that the rate is less than 75%. To test this, she randomly selects 100 people and finds that 80 of them lose their balance while standing on one foot. To determine if these data provide convincing evidence that the proportion of people who lose their balance while standing on one foot and closing their eyes is less than 75%, 150 trials of a simulation are conducted. The gymnast is testing the hypotheses: H0: p = 75% and Ha: p < 75%, where p = the true proportion of people who will lose their balance while standing on one foot and closing their eyes. Based on the results of the simulation, what is the estimate of the P-value of the test?

Answers

The P-value of the test is the probability of observing a sample proportion of 80/100 or less, given that the null hypothesis is true.

This can be calculated using the formula P(X <= x) = Σ (n x) p^(x) q^(n-x), where n = 100, x = 80, p = 0.75 and q = 1-0.75. Following this formula, the P-value of the test is calculated to be 0.0009. This means that there is a 0.0009 probability of observing a sample proportion of 80/100 or less, given that the null hypothesis is true. Therefore, the data provide convincing evidence that the proportion of people who lose their balance while standing on one foot and closing their eyes is less than 75%.The P-value of the test is the probability of observing a sample proportion of 80/100 or less, given that the null hypothesis is true.

Answers

When working with word problems, students should first read the problem and decide if it is a one-step or two-step problem.

A one-step problem involves solving for a single unknown quantity, such as finding the total cost of 10 pencils at $0.50 each. The formula for this would be C = Pn, where C is the cost, P is the price, and n is the number of items. To solve this problem, the student would multiply the price and number of items, so C = 0.50 x 10 = $5.00. A two-step problem involves solving for two unknowns, such as finding the total cost of 10 pencils at a 10% discount. The formula for this would be C = Pn (1 - r), where r is the discount rate. To solve this problem, the student would first calculate the discount by multiplying the price and number of items by the discount rate, so C = 0.50 x 10 x 0.10 = $0.50. Then the student would subtract the discount from the total cost, so C = 0.50 x 10 - 0.50 = $4.50.

Now, let's say 5th position number is x and 6th position number is y
So, we have 30 + x = y and x+ y = 128
Combining these 2 equation, we get: x + 30 + x = 128 or x = 49, so y = 79

thus from 4th position, the series can be written as

What is a Parallelogram ?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

A quadrilateral is a specific type of polygon known as a parallelogram if it contains two parallel opposed sides. A parallelogram has the following qualities:

The opposing sides are equal and parallel.Angles on either side are equal.The subsequent or neighboring angles are additional.All of the angles will be at right angles if any one of them is a right angle.The two diagonals are split in half.The parallelogram is divided into two congruent triangles by each diagonal.A parallelogram's total square sum and total square sum of its diagonals are equivalent. Also known as the parallelogram law.

Each coordinate of the Parallelogram :

P (-3, 0) , A(3, -1) , R ( 2, -5) and T(-4, -4)

Length of PA = √((3 + 3)² + (-1 - 0)²) = √(36 + 1) = √37

Lenght of TR = √((-4 - 2)² + (-4 + 5)²) = √(36 + 1) = √37

Length of PT = √((-3 + 4)² + (0 + 4)²) = √(16 + 1) = √17

Length of AR = √((3-2)² + (-1 + 5)²) = √(16 + 1) = √17

The chef needed a) 3¾ cups of lemon juice and b) 20 pints olive oil for the larger batch.

What is mixed fraction?

A mixed fraction is one that has both its quotient and remainder represented. A mixed fraction like 2 1/3 is one where the remainder is 1 and the quotient is 2. Therefore, a mixed fraction is made up of both a whole number and a correct fraction.

The recipe was for 4 person, but now here are 40

The scale multiple is = 40/4

                                   = 10

a) As 1 cup = 16 tablespoon

The number of tablespoon of lemon required for 40 men = 6 × 10

                                                                                                 = 60

Converting to cup = 60/16

                              = 3¾ cups

b) As 1 cup = 0.5 pints

The number of cups of olive oil required for 40 men = 1 × 10

                                                                                        = 10

Converting to pints = 10/0.5

The average variable cost function for reconstructive nose surgery is estimated to be:

What price should Dr. Williams charge to perform a nose operation?
How much profit does she earn each month?

tysm! :)​

Answers

The inverse demand function is P = 2400 + 5Q

The Marginal Revenue function is MR = 5QThe number of nose operations is 15The price per month is $2475Dr. Williams earns $19750 in profit each month

How to determine the inverse demand function

Given that

Q = 480 - 0.2P

We simply make P the subject of the formula

So, we have

0.2P = 480 - Q

Divide by 0.2

P = 2400 + 5Q

The marginal revenue function

To find the marginal revenue function, we can use the inverse demand function P = 2400 + 5Q, and take the derivative of this function with respect to Q.

The derivative of P with respect to Q is dP/dQ = 5. This represents the change in price for a one unit change in the quantity of operations performed.

So the Marginal Revenue function is MR = dP/dQ * Q = 5Q

The number of nose operations

To maximize profit, the doctor should equate marginal revenue to marginal cost, which is

MC = dAVC/dQ

So, we have

MC = d(2Q² - 15Q + 400)/dQ

Evaluate

MC = 4Q - 15.

So, we have

5Q = 4Q - 15

Q = -15

Take the absolute value

Q = 15

So, the number of operations is 15

The price for each operation

We have

P = 2400 + 5Q

This gives

P = 2400 + 5 * 15

Evaluate

P = 2475

The monthly profit

To find the profit, we need to subtract the total cost from the total revenue.

The total revenue is found by multiplying the price by the quantity of operations performed: TR = P * Q = 2475 * 15 = 37125

The total variable cost is found by multiplying the average variable cost by the quantity of operations performed: TVC = AVC * Q = (2Q^2 - 15Q + 400) * Q = 2Q^3 - 15Q^2 + 400Q

The total fixed cost is the fixed cost that doesn't change regardless of the level of output : TFC = $8000

The total cost is the sum of the total variable cost and total fixed cost: TC = TVC + TFC = 2Q^3 - 15Q^2 + 400Q + $8000

The profit is the difference between total revenue and total cost:

Help please I think I’m not sure which one is the answer, confused!!!

Answers

I believe it’s the 3rd answer.

Please help me!! It is 5 questions

Answers

1. 80 people attended only the FSU-Butler game.

2. 165. Since it's not possible to have negative number of people, the answer is 0.

3. 210 people attended at least two of these games.

4. 340 people attended the Marist and Butler games, but not the North Carolina State game.

5. 365 people attended the North Carolina State or the Butler game

How do you calculate this vendiagram? We know that 215 people attended the FSU-Butler game, and that 70 of      them also attended the NC State game and 65 of them also attended the Marist game. So, 215 - 70 - 65 = 80 people attended only the FSU-Butler game.We know that 460 people were surveyed in total, and 190, 215, and 220 attended the Marist, Butler and NC State games respectively. The number of people who attended at least one of these games is 190 + 215 + 220 = 625. Thus, 460 - 625 = -165. Since it's not possible to have negative number of people, the answer is 0.We know that 65 people attended the Marist and NC State games, 70 people attended the NC State and Butler games, and 65 people attended the Butler and Marist games. 10 people attended all three games. So, 65 + 70 + 65 + 10 = 210 people attended at least two of these games.We know that 190 people attended the Marist game, 215 people attended the Butler game, and 65 people attended both the Marist and Butler games. So, 190 + 215 - 65 = 340 people attended the Marist and Butler games, but not the North Carolina State game.We know that 220 people attended the North Carolina State game and 215 people attended the Butler game. 70 people attended both the North Carolina State and Butler game. So, 220 + 215 - 70 = 365 people attended the North Carolina State or the Butler game.

1/4(x - 12) use your understanding of writing expressions to translate the expression

Answers

The expansion of 1/4(x - 12) is x/4 - 3

What is expansion of expression?

In order to expand and simplify an expression, we need to multiply out the parentheses and then simplify the resulting expression by collecting the like terms. Expanding brackets (or multiplying out) is the process by which we remove parentheses. It is the reverse process of factorisation.

For example 4(3-y) can be expanded by multiplying the factor 4 by 3 and y = 12- 4y

Similarly the expression 1/4(x - 12) can be expanded by firstly multiply the factor ¼ by x and 12

therefore 1/4(x - 12) = 1/4×x -12×1/4

= x/4 - 3

Therefore the expansion of 1/4(x - 12) is x/4 -3
