Answer: Rs 1469

Step-by-step explanation:

Coat of item = RS 1300

Value added tax = 13%

The price of the item will then be calculated as:

= 1300 + (1300 × 13%)

= 1300 + (1300 × 0.13)

= 1300 + 169

= Rs 1469

An example of a +f(pxq) with integer coefficients that factors (poly mod nq), but has no roots is (x^2 + 1)(x^2 + 2). This polynomial satisfies the given conditions and demonstrates that it is possible to have a polynomial with integer coefficients that factors modulo n, but has no roots.

Let's consider the polynomial f(pxq) = (x^2 + 1)(x^2 + 2).
1. This polynomial has integer coefficients as both factors have integer coefficients.
2. Now, let's consider taking the modulo n, where n is any positive integer.
3. Since the modulo operation only affects the coefficients, we will still have a polynomial with integer coefficients after taking the modulo.
4. However, there are no integers x for which f(pxq) = 0 (poly mod n), as the factors x^2 + 1 and x^2 + 2 do not have any integer roots.

The company should use a chi-square goodness-of-fit test to determine if the rate of defects differs significantly across the four manufacturing plants.

This type of test is used to compare the observed distribution of categorical data to an expected distribution. In this case, the company can categorize each product as either defective or non-defective and compare the observed distribution of defects across the four plants to an expected distribution based on the overall rate of defects.

A chi-square goodness-of-fit test will determine if the observed differences in the rate of defects across the plants are statistically significant, meaning that they are unlikely to have occurred by chance.

If the test shows a significant difference, the company can conclude that the rate of defects does indeed differ significantly across the plants.

The total electric force on the 7.00−μC charge is 0.872 N at an angle of 330°.

The force exerted on the 7.00−μC charge by the 2.00−μC charge is

F₁​ ​= \(k_{e}\)q₁q₂​​/r₂ r^

= [(8.99×10⁹N.m²/C²)(7.00×10^−6C)(2.00×10^−6C) ×(cos60°i^+sin60°j^​)]/ (0.500m)²

F₁ ​= (0.252i^+0.436j^​)N

Similarly, the force on the 7.00μC charge by the −4.00−μC charge is

F₂​ ​= \(k_{e}\)q₁​q₃/​r² ​​r^

= [(8.99×10⁹N.m²/C²)(7.00×10^−6C)(−4.00×10^−6C)​×(cos60°i^−sin60°j^​)]/(0.500m)²

F₂​ ​=(0.503i^−0.872j^​)N

Hence, the total force on the charge 7.00−μC  is

F = F₁​​+F₂​

​=(0.755i^−0.436j^​)N

We can also note the total force as:

Step-by-step explanation:

The values of W and X that make NOPQ a parallelogram are:

W = -5w + 11

X = 3x

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size.

To determine the values of W and X that make NOPQ a parallelogram, we need to find the conditions under which the opposite sides of the quadrilateral are parallel.

The coordinates of the points N, O, P, and Q are given as follows:

N: (w+7, 5w-5)

O: (3/2x, 3)

P: (?, ?)

Q: (?, ?)

For NOPQ to be a parallelogram, the vector from N to O should be equal to the vector from P to Q, and the vector from O to P should be equal to the vector from Q to N.

The vector from N to O is:

NO = (3/2x - (w+7), 3 - (5w-5))

   = (3/2x - w - 7, -5w + 8)

The vector from O to P should be equal to the vector from Q to N. Thus:

OP = (P_x - (3/2x), P_y - 3)

QN = ((w+7) - Q_x, (5w-5) - Q_y)

Equating the corresponding components, we get the following equations:

3/2x - w - 7 = P_x - (3/2x)

-5w + 8 = P_y - 3

w + 7 = (w+7) - Q_x

5w - 5 = (5w-5) - Q_y

Simplifying these equations, we find:

P_x = 3x

P_y = -5w + 11

Q_x = w + 7

Q_y = 5w

Therefore, the values of W and X that make NOPQ a parallelogram are:

W = -5w + 11

X = 3x

The volume of the parallelepiped is 20 cubic units.

To find the volume of a parallelepiped, we can use the determinant of a matrix formed by the vectors corresponding to three edges of the parallelepiped.

Let's denote the vectors formed by the edges AB, AC, and AD as u, v, and w, respectively.

u = B - A = (2, 5, 0) - (0, 0, 0) = (2, 5, 0)

v = C - A = (0, -4, 5) - (0, 0, 0) = (0, -4, 5)

w = D - A = (2, -3, 6) - (0, 0, 0) = (2, -3, 6)

Now, we can form a matrix with u, v, and w as its columns:

M = [u, v, w] = [[2, 0, 2], [5, -4, -3], [0, 5, 6]]

The volume of the parallelepiped is then given by the absolute value of the determinant of M:

Volume = |det(M)| = |2(30) - 0(6) + 2(-20) - 0(5) + 2(0) - 2(0)| = |60 + 0 - 40 - 0 + 0 - 0| = |20|

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get \(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

Let's consider that s be the length of a side of the regular pentagon.

The perimeter of the regular pentagon will be 5s. Therefore, we have the equation:5s = 140s = 28 cm

Also,

we have the formula for the area of a regular pentagon as:

\($A=\frac{1}{4}(5 +\sqrt{5})a^{2}$,\)

where a is the length of a side of the pentagon.

In order to represent the area of a regular pentagon whose perimeter is 140 cm, we need to substitute a with s, which we have already calculated.

Therefore, we have:\(A(s) = $\frac{1}{{4}(5 +\sqrt{5})s^{2}}$\)

Now, we have successfully used function notation (with the appropriate functions above) to represent the area of a regular pentagon whose perimeter is 140 cm.

The area of a regular pentagon can be represented using function notation (with the appropriate functions above). The first step is to calculate the length of a side of the regular pentagon by dividing the perimeter by 5, since there are 5 sides in a pentagon.

In this case, we are given that the perimeter is 140 cm, so we get 5s = 140, which simplifies to s = 28 cm. We can now use the formula for the area of a regular pentagon, which is\(A = (1/4)(5 + sqrt(5))a^2\), where a is the length of a side of the pentagon.

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get\(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

The value of the correlation coefficient is 0.34. Thus, the option (B) 0.34 is the correct answer.

Given that a researcher measures the relationship between two variables, X and Y.

If SS(XY) = 340 and SS(X)SS(Y) = 320,000, then we need to calculate the value of the correlation coefficient.

Correlation coefficient:

The correlation coefficient is a statistical measure that determines the degree of association between two variables.

It is denoted by the symbol ‘r’.

The value of the correlation coefficient lies between -1 and +1, where -1 indicates a negative correlation, +1 indicates a positive correlation, and 0 indicates no correlation.

How to calculate correlation coefficient?

The formula to calculate the correlation coefficient is as follows:

r = SS(XY)/√[SS(X)SS(Y)]

Now, substitute the given values, we get:

r = 340/√[320000]r = 0.34

Therefore, the value of the correlation coefficient is 0.34. Thus, the option (B) 0.34 is the correct answer.

The slope coefficient in a regression model represents the change in the response variable for a one-unit change in the predictor variable, holding all other predictors constant.

The significance of the slope coefficient is determined by the p-value associated with it in the regression output. A p-value less than 0.05 indicates that the slope coefficient is significantly different from zero at a 5% level of significance, meaning that the predictor variable has a significant effect on the response variable. A p-value greater than 0.05 suggests that the predictor variable does not have a significant effect on the response variable.
