Answer:

Cost = y/x

Step-by-step explanation:

The cost of a 4 pack of apple juice is $ 2.24.

We need to write an equation that relates the cost in dollars, y, to the number of apple juice cartons, x.

As 4 packs = $2.24

1 pack = 0.56

So, the equation can be :

Cost = y/x

Answer:

D. 3/4

Step-by-step explanation:

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Selling price= $60

Unitary variable cost= $28

Fixed costs= $15,000

First, we need to calculate the average total cost:

Average cost= total cost / number of units

For example, for 1 unit and 10,000 units:

1 unit:

Average cost= 15,028/1 = 15,028

10,000 units:

Average cost= (15,000 + 28*10,000) / 10,000

Average cost= $29.5

Now, we can calculate the break-even point in units:

0= (60*x) - (28*x) - 15,000

x= number of units to break-even

0= 32x - 15,000

15,000/32= x

468.75=x

break-even point in units= 469

For the desired profit of $10,000:

10,000 = (60*x) - (28*x) - 15,000

25,000= 32x

781.25= x

Break-even point= 782 units

Finally, fixed costs dropped by $8,000:

0= 32x - 7,000

x= 7,000/32

x= 218.75

Break-even point= 219

Difference= 250 units

This is a lengthy question ill go through all the formulas

This is a right triangle which means u can use pythagorean theorem to find QP

formula :

\(a^{2} +b^{2} =c^{2}\)

Note that \(c^{2}\) is always the hypotenuse(the hyp is always opposite to ninety degrees)

so lets substitute

=> \(a^{2} +17^{2} =28^{2}\)

=> \(a^{2} +289 =784\)

subtract 289 both sides

\(= > a^{2}=495\)

Now square root both

\(\sqrt{ a}^{2}=\sqrt{495}\)

==> \(3\sqrt{55}\) or 22.2 (answer)

The probability is the ratio of the favorable event to the total number of events. Then the probability of the elk caught in the park being unmarked will be 92.44%.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

The total number of elk is 5,625.

The number of elk that were marked is 225.

Then the number of elk that were unmarked will be

→ 5625 - 225 = 5,200

Then the probability of the elk caught in the park being unmarked will be

\(\rm P = \dfrac{5200}{5625}\\\\P = 0.9244 \ or \ 92.44\%\)

If ε = 1, the maximum value of δ that satisfies the condition |x - 1|. satisfied <; δ means |2x - 2| <; ε is δ ≤ 0.5. For ε = 0.1, the maximum value of δ that satisfies the condition is δ ≤ 0.05 for largest number.

We need to find the maximum value of δ such that |x - 1|. Applies <; δ, then |2x - 2| <; e.

If \(ε = 1\):

We begin by analyzing the inequality |2x - 2|. <; 1. Simplify this inequality to -1 <. 2x - 2 <; 1. Add 2 to all parts of the inequality and you get 1 <. 2x < 3. Dividing by 2 gives 0.5 < × < 1.5. Since the difference between the upper and lower bounds is 1, the maximum value of δ is 0.5.

If \(ε = 0.1\):

Apply the same procedure to the inequality |2x - 2|. Simplifying to < by 0.1 gives -0.1 <. 2x - 2 <; Add 2 to every part of 0.1 and you get 1.9 <. 2x < 2.1. Divide by 2 to get 0.95 <. × < 1.05. The difference between the upper and lower bounds is 0.1, so the maximum value of δ is 0.05.

Therefore, \(ε = 1 δ ≤ 0.5 and ε = 0.1 δ ≤ 0.05\).

Answer:

Step-by-step explanation:

As the angle of the incline increases, the normal force decreases, which decreases the frictional force. The incline can be raised until the object just begins to slide.

Hari does 7,056 joules of work while dragging the load of 60 kilograms along a distance of 12 meters. The type of work performed in this scenario is mechanical work.

The amount of work done can be calculated using the formula:

Work = Force × Distance × cos(θ)

In this case, the force applied by Hari is equal to the weight of the load, which can be calculated using the equation:

Force = Mass × Acceleration due to gravity

Given that the mass of the load is 60 kilograms and the acceleration due to gravity is approximately 9.8 m/s², the force can be calculated as:

Force = 60 kg × 9.8 m/s² = 588 N

Since the force and distance are in the same direction, the angle (θ) between them is 0°, and therefore the cosine of 0° is 1.

Plugging in the values into the work formula:

Work = 588 N × 12 m × cos(0°)

    = 588 N × 12 m × 1

    = 7,056 N·m (joules)

Hence, Hari does 7,056 joules of work while dragging the load. This work is categorized as mechanical work since it involves the application of a force to move an object along a distance.

Answer:

Step-by-step explanation:

This linear equation system has a unique solution, which means it has only one solution.The given equations are:

Y = -6x + 2
-12 - 2y = -4

To find the number of solutions for this linear equation system, we can start by solving one equation for one variable and then substituting the solution into the other equation.

Let's solve the first equation, Y = -6x + 2, for Y:

Y = -6x + 2

Now let's solve the second equation, -12 - 2y = -4, for y:

-12 - 2y = -4

Adding 12 to both sides of the equation:

-2y = 8

Dividing both sides of the equation by -2:

y = -4

Now, we can substitute the value of y into the first equation:

Y = -6x + 2

Y = -6x + 2

Since Y is equal to -6x + 2 and y is equal to -4, we can set the two expressions equal to each other:

-6x + 2 = -4

Adding 4 to both sides of the equation:

-6x + 6 = 0

Subtracting 6 from both sides of the equation:

-6x = -6

Dividing both sides of the equation by -6:

x = 1

So, the solution to this linear equation system is x = 1 and y = -4.

Therefore, this linear equation system has a unique solution, which means it has only one solution.

Answer:

Step-by-step explanation:

The probability that the sample average is more than 8.47 is 0.4406 if the pH level of the reservoir is ok

To calculate this, we will use a standard normal distribution table and the Z-score formula.

First, we need to calculate the Z-score for the sample average of 8.47. This is done by using the Z-score formula:

Z-score = (x - mean)/standard deviation

where x is the sample average, mean is the average of all samples, and standard deviation is the standard deviation of all samples.


In this case, the Z-score is:

Z-score = (8.47 - 8.50)/0.22 = -0.14


Then, we need to look up the Z-score in a standard normal distribution table. The probability of the sample average being more than 8.47 is equal to 1 minus the Z-score probability. So, in this case, the probability of the sample average being more than 8.47 is equal to 1 - 0.5594 = 0.4406.

Therefore, the probability that the sample average is more than 8.47 is 0.4406 if the pH level of the reservoir is ok.

The probability that a randomly selected student from the school have a cold after receiving the flu vaccine is 0.27 or 27%.

The school nurse is hoping to limit the cold's spread among the students in her school. To do this, to administer flu vaccines to the students. However, the flu vaccine is only effective in preventing the cold in 75% of cases.

Now, let's calculate the probability that a randomly selected student from the school have a cold after receiving the flu vaccine.

Let:

P(Cold) be the probability of having a cold in the city (given as 64% or 0.64).

P(Not Cold) be the probability of not having a cold in the city (since P(Cold) + P(Not Cold) = 1).

P(Vaccine Effective) be the probability that the flu vaccine is effective (given as 75% or 0.75).

The probability of not having a cold after receiving the flu vaccine is given by:

P(Not Cold | Vaccine) = P(Not Cold) × P(Vaccine Effective)

P(Not Cold | Vaccine) = (1 - P(Cold)) × P(Vaccine Effective)

P(Not Cold | Vaccine) = (1 - 0.64) × 0.75

P(Not Cold | Vaccine) = 0.36 × 0.75
