To make three plates by three machines it will take 05 minutes.

The Production Possibility Frontier (PPF) is a curve on a graph that represents the possible amount that can be produced by two products if they rely on the same finite resource for manufacturing. PPF is also known as the production possibility curve.

Given:

05 machines make 05 plates in 05 hours.

rate of 3 machines is 1 plate per minute,

1 machine makes 5 Plate in = 5 × 5 = 25 minutes.

1 machine makes makes 1 plate in = 25 ÷ 5 = 5 minutes

So, 1 machine can make 03 plates in = 5 × 3 = 15

Thus, 03 machines can make 03 plates in = 15 ÷ 3

                                                                      = 5 minutes.

Three dozen of these apples cost if Annalisa bought is equivalent to $23.40.

Given that:

Annalisa bought two dozen apples for $15.60.

Therefore, the value of one dozen apples will be calculated by dividing both values by 2.

i.e. We can say that,

Annalisa bought one dozen apples for $15.60/2 = $7.80.

So, we have to find out the value of three dozen of these apples.

Hence, we multiply both the 3 to get the cost of three dozen of apples.

Multiplying we get,

Annalisa if bought three dozen apple costs = $7.80 x 3 = $23.40.

We also know that, one dozen = 12 apples

So, three dozen = 36 apples

Therefore, we can say the cost of one apple = 23.40/36 = $0.65

Hence, it costs $23.40 for three dozen apples to Annalisa.

Multiply your number by 2/3. If you have a whole number, divide it by a denominator of 1 to get a fraction.

Calculate numerator times numerator, then denominator times denominator when multiplying fractions. For instance, multiply 2/3 x 18/1 to get 36/3 in order to discover two thirds of 18.

Divide the resulting fraction by the common denominator to reduce it as necessary. For instance, 36 and 3 both have 3 as their common denominator. You get a fraction of 12/1 when you divide 36 and 3 by 3, which is equal to 12. Therefore, 12 is equal to 2/3 of 18.

Answer:

To find the total annual interest on Nora's two investments, we need to calculate the interest earned on each investment and then add the two amounts together. To find the interest earned on the first investment, we need to multiply the amount invested by the interest rate and the length of time the investment is held. The investment of $800 is held for one year, so the interest earned on this investment is $800 x 6% x 1 = $48. To find the interest earned on the second investment, we need to use the same formula. The investment of $1200 is also held for one year, so the interest earned on this investment is $1200 x 7% x 1 = $84. The total interest earned on both investments is $48 + $84 = $132. Therefore, Nora's total annual interest on these two investments is $132.

The ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.

Step-by-step explanation:

The ratio of Pablo's age to Richard's age is 6: 7 and the ratio of Pablo's age to Tristan's age is 5: 4. To find the ratio of Pablo's age to Richard's age to Tristan's age, we can first find the ratio of Richard's age to Tristan's age by multiplying the ratios of Pablo's age to Richard's age and Pablo's age to Tristan's age. The product of these ratios is 6/7 * 5/4 = 30/28. Since the ratio of Pablo's age to Richard's age is 6:7, we can add this ratio to the ratio of Richard's age to Tristan's age to find the ratio of Pablo's age to Richard's age to Tristan's age. Thus, the ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.

The diameter of Raquel's "trashball" should be equal to 5 inches.

The circumference of the "trashball" should be equal to 15.7 inches.

In order to calculate the circumference of Raquel's trashball, we would use the formula for the circumference of a circle. Mathematically, the circumference of a circle can be calculated by using this formula:

C = 2πr

C = πD

Where:

Since Raquel wants the "trashball" to have a diameter that is 1/4 the diameter of the top of the trash can, we have;

Raquel's trashball diameter = 1/4 × diameter of the top of the trash can.

Raquel's trashball diameter = 1/4 × 20

Raquel's trashball diameter = 5 inches.

Next, we would determine the circumference of the "trashball" as follows;

The number of hours it will take 3 employees to tag all garments is 1.60 hour

From the question, we have the following parameters that can be used in our computation:

Number of garments = 575

Time taken by an employee on a garment = 30 seconds

This means that the variation is an inverse variation

If the time taken by an employee on a garment is 30 seconds

Then the time taken by 3 employees on a garment is

Time taken = 30 seconds/3

Evaluate

Time taken = 10 seconds

For 575 garments, we have

Time taken = 10 seconds * 575

Evaluate

Time taken = 5750 seconds

Express in hours

Time taken = 1.60 hour

Hence, the time taken is 1.60 hour

The second bar is labeled Dolphins, with freshmen from 0 to 45 percent and sophomores from 45 to 100 percent, and the third bar is labeled Buccaneers, with freshmen from 0 to 45 percent and sophomores from 45 to 100 percent.

If 160 students selected Jaguars, how many of those students are sophomores?

a. 64 students

b. 72 students

c. 88 students

d. 96 students

Answer:

x = 72

Step-by-step explanation:

We first remove the parenthesis

2x-90+2x-90+x = 180

Group like terms

2x+2x+x-90-90 = 180

Add the like terms with each other

5x-180 = 180

Add 180 to both sides to cancel the -180 on the left side of the equation

5x = 180+180 = 360

We then divide 360 by 5 to get 72 as x

The probability that a random sample of 60 households will have exactly 20 households with 3 or more vehicles is 0.90931

What is mean and standard deviation?

Using Normal Approximation to Binomial

Mean = n * P = ( 60 * 0.3 ) = 18

Variance  = n * P * Q  = ( 60 * 0.3 * 0.7 ) = 12.6

Standard deviation  = √(variance) = √(12.6)  = 3.5496

P ( X = 20 )

Using continuity correction

P( n - 0.5 < X < n + 0.5 )

= P ( 20 - 0.5 < X < 20 + 0.5 )

= P ( 19.5 < X < 20.5 )

Using EXCEL,

P ( 19.5 < X < 20.5 )

= P(X < 20.5) - P(X < 19.5)

= BINOM.DIST ( 20.5 , 60 , 0.30, TRUE) - BINOM.DIST ( 19.5 , 60 , 0.30, TRUE)

= 0.7622 -  0.66916

= 0.0931

The inequality y < -1/2x² - 6x - 16 corresponds to the right representation.

Along with passing through (-8, 0), (-6, 2), and (-4, 0), it also has a vertex there.

We need to find its equation.

We must take into account the provided details on the parabola's properties and its points in order to choose the proper inequality to symbolize the shaded area of the parabola.

The vertex of the parabola is at (-6, 2), and it opens downward. This indicates that the equation for the parabola is of the type y = a(x - h)² + k, where (h, k) denotes the vertex.

In this case, h = -6 and k = 2.

Plugging in the values of the vertex into the equation, we have:

y = a(x - (-6))² + 2

y = a(x + 6)² + 2

Now we can use one of the points that the parabola passes through to solve for the value of 'a'.

The point (-8, 0) lies on the parabola. Substituting these values into the equation:

0 = a(-8 + 6)² + 2

0 = a(-2)² + 2

0 = 4a + 2

4a = -2

a = -1/2

Substituting the value of 'a' into the equation:

y = (-1/2)(x + 6)² + 2

Expanding and rearranging the equation:

y = (-1/2)(x² + 12x + 36) + 2

y = (-1/2)x² - 6x - 18 + 2

y = (-1/2)x² - 6x - 16

Therefore, the correct inequality that represents the shaded region is:

y < -1/2x² - 6x - 16

Solving by elimination

4x + 5y = 75

(4x + 5y = 75) × -1

-4x - 5y = -75

-4x - 5y = -75

4x + 4y = 65

         -y = -10

         ÷-1   ÷-1

       --------------

          y = 10

4x + 4y = 65
