Answer:

x = t(a+p)/4

Step-by-step explanation

Given the expression

​a=4x/t - p

We are to make x the subject of the formula

a=4x/t - p

Add p to both sides

a+p = 4x/t - p+p

a+p = 4x/t

Cross multiply

t(a+p) = 4x

Rearrange

4x = t(a+p)

Divide both sides by 4

4x/4 = t(a+p)/4

x = t(a+p)/4

Answer:

Answer:

Independent variable: Number of laptops

Dependent variable: Grades

Step-by-step explanation:

According to the Question,

If we have coins = [1, 2, 5] and amount = 5, then the function should return 4, because there are four combinations of coins that make up an amount of 5: [1, 1, 1, 1, 1], [1, 1, 1, 2], [1, 2, 2], and [5].

This problem can be solved using dynamic programming. Let's define dp[i][j] as the number of combinations of coins using the first i coins to make up an amount j. Then we can use the following recurrence relation:

dp[i][j] = dp[i-1][j] + dp[i][j-coins[i]]

The first term on the right-hand side of the equation corresponds to the case where we don't use the i-th coin, while the second term corresponds to the case where we use the i-th coin at least once. Note that we only need to consider cases where j >= coins[i], because it's impossible to make up an amount less than the value of the i-th coin using that coin.

We can initialize dp[0][0] = 1, because there is exactly one way to make up an amount of zero using no coins. Finally, the answer to the problem is dp[n][amount], where n is the total number of coins.

Here's the Python code:

def change(amount, coins):

   n = len(coins)

   dp = [[0] * (amount+1) for _ in range(n+1)]

   dp[0][0] = 1

   for i in range(1, n+1):

       dp[i][0] = 1

       for j in range(1, amount+1):

           dp[i][j] = dp[i-1][j]

           if j >= coins[i-1]:

               dp[i][j] += dp[i][j-coins[i-1]]

   return dp[n][amount]

For example, if we have coins = [1, 2, 5] and amount = 5, then the function should return 4, because there are four combinations of coins that make up an amount of 5: [1, 1, 1, 1, 1], [1, 1, 1, 2], [1, 2, 2], and [5].

Note that where in a parallelogram, if m < PQL = 39°, then m < QLM = 141°. This was solved using the properties of the angles in a parallelogram.

A parallelogram is a quadrilateral (a four-sided polygon) with two pairs of parallel sides. Some of the properties of the internal angles of a parallelogram are:

Opposite angles are congruent: The opposite angles of a parallelogram are equal in measure. In other words, if we label the angles of a parallelogram as A, B, C, and D, then angle A is congruent to angle C, and angle B is congruent to angle D.

Consecutive angles are supplementary: The consecutive angles of a parallelogram add up to 180 degrees. In other words, angle A + angle B = 180 degrees, angle B + angle C = 180 degrees, angle C + angle D = 180 degrees, and angle D + angle A = 180 degrees.

Since the angle given as consecutive (See attached image), therefore:

m < QLM + m < PQL = 180°

Thus,

m < QLM  =  180° - m < PQL

m < QLM  =  180° - 39°; Thus,

m < QLM  =  141°

Thus, if m < PQL = 39°, then m < QLM = 141°.

Answer:

1.48 m

Step-by-step explanation:

In a class of 32 students

the mean height of the 14 boys is 1.56 meters.

the mean height of all 32 students is 1.515 meters.

Total number of students = 32

Mean height of all students = 1.515

We can obtain the sum of all student's height :

Number if students * mean height

= 32 * 1.515

= 48.48

Number of boys = 14

Mean height of boys = 1.56m

We can obtain the sum of all boys height :

Number if students * mean height

= 14 * 1.56

= 21.84

Number of girls :

All students - Number of boys

32 - 14 = 18

Sum of girls height :

48.48 - 21.84 = 26.64

Mean height of girls :

Sum of girls height / Number of girls

26.64 / 18

= 1.48 m

Surface area = 400 ft²

Volume = 448 ft³

length = 4 ft

width = 8 ft

height = 14 ft

The storage chest is a rectangular prism in shape

We use volume of rectangular prism formula:

Hence, the volume of the storage chest is 448ft³

Surface area of rectangular prism = 2(lw + hw + hl)

Surface area = 2(4 × 8 + 14 × 8 + 14 × 4)

Surface area = 2(32 + 112 + 56)

Surface area = 2(200)

Surface area = 400 ft²

Surface area of the chest = 400 ft²

The contribution margin per unit is $ 1.50

The contribution margin is the percentage of a product's sales revenue that isn't consumed by variable costs and goes toward paying the firm's fixed expenses.

One of the main components of break-even analysis is the idea of contribution margin.

Labor-intensive businesses with few fixed expenses tend to have low contribution margins, whereas capital-intensive, industrial businesses have more fixed costs and, thus, higher contribution margins.

According to the question,

Total expenses per unit = $(5.50+3.00+1.50+4.00+2.50+2.00+1.00+0.50)

                                        = $ 20

Selling Price per unit = $ 21.50

Thus, contribution margin per unit = $ (21.50 - 20)

                                                         = $ 1.50

When one of the stars in a spectroscopic binary system is moving toward the Earth in its orbit, we observe a shift in its spectral lines towards shorter wavelengths, known as a blue shift.

The shift in the spectral lines towards shorter wavelengths is caused by the Doppler effect. This effect occurs when there is relative motion between the source of the waves (in this case, the star) and the observer (in this case, the Earth). When the star is moving towards the Earth, the waves are compressed and the wavelength is shortened, resulting in the blue shift.

Spectroscopic binary systems are a type of binary star system where the stars are too close together to be resolved visually, but their spectra can be observed separately. By measuring the spectral lines of the stars, astronomers can determine their velocities and orbital parameters. When one of the stars in a spectroscopic binary system is moving towards the Earth in its orbit, we observe a blue shift in its spectral lines. This blue shift is caused by the Doppler effect, which is a change in the wavelength of waves due to the relative motion between the source of the waves and the observer. In the case of a moving star, the waves are compressed as the star moves towards the Earth, resulting in a shorter wavelength and a blue shift.

The likelihood of it not raining both days day is 0.28, or 28%.

Who is the originator of probability?

An exchange if letters between two important mathematicians--Blaise Pascal or Pierre de Fermat--in the mid-17th century laid the groundwork for probability, transforming the way mathematicians and scientists regarded uncertainty and risk.

for Monday is 1 - 0.6 = 0.4 while the probability of rain for Thursday equals 1 - 0.3 = 0.7.

Because we assume that rain on Monday or rain on Thursday were independent events, the likelihood of no precipitation for both days is simply a function of the probabilities for zero rain on each day.

So the chances of it not raining on either day are:

P(no rain Monday and Thursday) = P(no rainfall Monday) x P(no rain Thursday) = 0.4 x 0.7 = 0.28

As a result, the likelihood of it not raining both days day is 0.28, or 28%.

We can use the iterative refinement method to improve the given approximate solutions of the system of linear equations. The iterative refinement method involves the following steps:

Solve the system of linear equations using the given approximate solutions to get a new approximate solution.

Use the new approximate solution to solve the system of linear equations again.

Repeat steps 1 and 2 until the desired level of accuracy is achieved.

Using the given approximate solutions, we have:

2(2) + 5(-3) + (8)/6 = -5/3

6(2) + 2(-3) + (8)/3 = 12

(2) + 2(-3) + (8)/3 = 3

The above system of linear equations can be written in the form of AX = B, where:

A = [[2, 5, 1/6], [6, 2, 1/3], [1, 2, 1/3]]

X = [x1, x2, x3]

B = [-5/3, 12, 3]

Now, we can use the iterative refinement method to improve the given approximate solutions:

First iteration:

Solve AX = B using X = [2, -3, 8]:

AX = [(-4/3), (-4), (26/3)]

B - AX = [-1/3, 16, (5/3)]

New X = [2, -3, 8] + [-1/3, 16, (5/3)] = [5/3, 13, (29/3)]

Second iteration:

Solve AX = B using X = [5/3, 13, (29/3)]:

AX = [(-13/9), (142/9), (34/9)]

B - AX = [(-16/9), (94/9), (7/9)]

New X = [5/3, 13, (29/3)] + [(-16/9), (94/9), (7/9)] = [(23/9), (235/9), (44/3)]
