What is arithmetic?

Arithmetic is an elementary a part of arithmetic that consists of the study of the properties of the normal operations on numbers—addition, subtraction, multiplication, division, involution, and extraction of roots.

Main body:

Henry read for 20 minute each day.

Alicia rate for 30 minute each day.

as they read 7 day of a week , so

total minutes read by Henry = 2 *7 *20

                                               = 280 minutes

total minutes read by Alicia = 2 *7 *30

                                              =420 minutes

difference between henry , alicia reading = 420 - 280 = 140 minutes.

Hence , Alicia read 140 minutes more then Henry in 2 week .

Answer:

2+i or 2-i (D)

Step-by-step explanation:

First you use the quadratic formula.  X= (-b +/- \(\sqrt{b^{2}-4ac }\))/2a

a=1

b=-4

c=5

X= (4 +/- \(\sqrt{16-20}\))/2

X=(4 +/- \(\sqrt{-4}\))/2

The square root of -4 is 2i.  i=√-1.  Therefore 2i= 2√-1 .If you simplify that, it becomes  √-4i.  

X= (4+/- 2i)/2

X= 2+/-i

X= 2+i or 2-i

The required △QST is similar to △URT by the AAA similarity postulate.

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

Here,

The question seems to be incomplete, assuming that triangles are equilateral triangles.

Consider the triangle,
△QST and △URT.
∠Q = ∠U     [as meaure of angle is 60°]
∠S = ∠R      [as meaure of angle is 60°]
∠T = ∠T      [as meaure of angle is 60°]

So,
△QST ~△URT by AAA similarity postulate.

So,
QS/UR = ST/RT  = QT/UT

Thus, the required △QST is similar to △URT by the AAA similarity postulate.

The number of degrees of​ freedom is 19.

Given:

sample size of first sample, n₁ = 20

sample size of second sample, n₂ = 20

Counts of differences between the paired observations of the two groups are used to calculate the degrees of freedom of two related populations.

In paired data, n = n1 = n2 means that there are the same number of observations in each group.

Here we have n = n₁ = n₂= 20

Degree of freedom is,

df = n - 1

    = 20 - 1

     = 19

We can write the parametric equation for the curve as c(t) = (t, 9 - 4t).

The given equation is y = 9 - 4x. To express this equation in parametric form, we need to rearrange it to obtain x and y in terms of a third variable, usually denoted as t.

By rearranging the equation, we have x = t and y = 9 - 4t.

Thus, we can write the parametric equation for the curve as c(t) = (t, 9 - 4t).

This means that for each value of t, we can find the corresponding x and y coordinates on the curve.

Therefore, the correct option is B: c(t) = (t, 9 - 4t).

Note: A parametric equation is a way to represent a curve by expressing its coordinates as functions of a third variable, often denoted as t. By varying the value of t, we can trace out different points on the curve.

To solve this system of equations using linear combination (also known as elimination or addition method), we need to eliminate one of the variables by adding or subtracting the equations. Here's one way to do it:

1. Multiply the first equation by 3 and the second equation by -5 to create opposite coefficients for the x-term:

```

15x + 12y = -42  (multiplying the first equation by 3)

-15x - 30y = -30  (multiplying the second equation by -5)

```

2. Add the two equations together to eliminate the x-term:

```

15x + 12y = -42

-15x - 30y = -30

--------------

0x - 18y = -72

```

3. Solve for y by dividing both sides by -18:

```

0x - 18y = -72

y = (-72)/(-18)

y = 4

```

4. Substitute y = 4 into one of the original equations to solve for x:

```

5x + 4y = -14

5x + 4(4) = -14

5x + 16 = -14

5x = -30

x = -6

```

So the solution to the system of equations is x = -6 and y = 4, or (-6, 4) as an ordered pair.

The value of the given integral along the straight line joining (1, 0) and (3, 2) is 4.

Let us denote the given curve as C. We are asked to evaluate the given integral along the straight line joining (1, 0) and (3, 2). Now, we know that work done by a force F along a curve C is given by:W = ∫CF.ds

where F is the force and ds is the infinitesimal displacement along the curve C.

This integral is path-dependent. It means that it takes different values depending on the path we choose to move from one point to another.To evaluate the given integral along a straight line joining the two points (1, 0) and (3, 2), we can use the following parametric form of the line segment.

Let's assume that t varies from 0 to 1 along this line segment. Then we can define the straight line joining (1, 0) and (3, 2) as follows:x = 1 + 2ty = 2t

Next, let us substitute these equations into the given integral to obtain a single variable integral as follows:

Integrating the expression from (1,0) to (3,2) of (x+2y)dx + (2x-y)dy:

We first evaluate the integral with respect to x:

- From x=1 to x=3, we have [(1+2t)+2(2t)]dx = (1+6t)dx.

- Next, we integrate this expression with respect to t from 0 to 1.

Then, we evaluate the integral with respect to y:

- From x=1 to x=3, we have [2(1+2t)-(2t)]dy = (2+4t-2t)dy.

- Since there are no y terms in the integrand, integrating with respect to y does not affect the result.

Combining the results of the two integrals, we have:

Integral = Integral of (1+6t)dt from 0 to 1.

Evaluating this integral, we get:

Integral = 1 + 6 * (1/2)

Integral = 4

Therefore, the value of the integral is 4.Therefore, the value of the given integral along the straight line joining (1, 0) and (3, 2) is 4.

The given statement is false because the t distribution is not appropriate if it does not follow the bell curve.

In the given question we have to answer that the given statement is true and false.

The given statement is:

When constructing a confidence interval for a sample proportion, the t distribution is appropriate if the sample size is small.

The given statement is false because the t distribution is not appropriate if it does not follow the bell curve.

When data are presented on a graph, they follow a bell-shaped pattern known as the t-distribution, with the majority of observations occurring near to the mean and relatively few occurring in the tails.

Predatory pricing. Predatory pricing occurs when a dominant firm intentionally sets its prices below the cost of production or below its competitors' prices in order to eliminate competition and deter new entrants into the market.

In this scenario, Firm A, the monopolist, engages in predatory pricing by reducing its prices in response to the entry of Firm B into the market. The aim is to make it financially difficult for Firm B to survive and eventually force it out of the market. By lowering its prices, Firm A hopes to attract customers away from Firm B and regain its monopoly power.

Predatory pricing is considered an anti-competitive practice and is often illegal in many jurisdictions. It can harm competition, limit consumer choice, and lead to higher prices in the long run. Regulatory bodies and competition authorities closely monitor such practices and may take legal action against firms found engaging in predatory pricing.

Overall, predatory pricing is a strategy employed by dominant firms to protect or strengthen their market position by driving out competitors. However, it is important for regulators to enforce antitrust laws to ensure fair competition and protect the interests of consumers and smaller market players.

x would be the side-length of a square that has the same area as a rectangle with width b and length a.

√(a*b) = x

Notice that you have two "lengths" which are a and b.

And you want to find x such that:

a/x = x/b

Now, notice that w e can rewrite the above expressions as:

a*b  = x*x

This means that x would be the side-length of a square that has the same area as a rectangle with width b and length a.

Now, if you know the values of a and b (you can get these by using a ruler for example)

Then you can replace them in the equation:

If an auditorium has 20 rows of seats. there are 20 seats in the first row, 21 seats in the second row, 22 seats in the third row, and so on. then,  there are 39 seats present in the 17th row.

The given data is as follows:

Number of rows of seats = 20

Number of seats in the first row = 20

Number of seats in the second row = 21

Number of seats in the third row = 22 and so on.

Let's calculate the common difference between the seats,

common difference = 21-20 = 1 or 22-21 = 1

Therefore common difference = 1

Then the number of the seats in 17th row will be

The number of the seats = 20 + (20 - 1)* 1

The number of the seats= 39 seats.

Therefore, there are a total of 39 seats present in the 17th row.
