The marked price of the article is Rs18000

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

Discount = 15%

VAT = 13%

Amount paid = Rs 17289

Using the above as a guide, we have the following

Amount paid = Marked price * (1 - discount) * (1 + VAT)

Substitute the known values in the above equation, so, we have the following representation

17289 = Marked price * (1 - 15%) * (1 + 13%)

So, we have

Marked price = 17289/[(1 - 15%) * (1 + 13%)]

Evaluate

Marked price = 18000

HEnce, the price is Rs18000

The area of a square can be found by using the following expression:

where "A" is the area and "l" is the length of each side of the square. The square on this problem has an area of 9 cm², so we can find the sides by replacing A for 9 on the expression above.

To solve it we need to take the square root on both sides of the equation.

Each side of the square has a length of 3 cm, so the sides are 3 cm x 3 cm.

The distance from the point to the given plane is 16/7 units.

To find the distance from a point to a given plane, we can use the formula:

distance = |ax + by + cz - d| / √(a^2 + b^2 + c^2)

where (x, y, z) are the coordinates of the point, and a, b, c, and d are the coefficients of the plane equation.

In this case, the point is (1, -3, 4) and the plane equation is 3x + 2y + 6z = 5.

Let's plug in the values:

distance = |(3*1) + (2*(-3)) + (6*4) - 5| / √(3^2 + 2^2 + 6^2)

Simplifying:

distance = |3 - 6 + 24 - 5| / √(9 + 4 + 36)
distance = |16| / √49
distance = 16 / 7

Therefore, the distance from the point (1, -3, 4) to the plane 3x + 2y + 6z = 5 is 16/7 units.

The probability that the vehicle Bob chooses is used or is a car is 0.6

There are 10 new cars, 4 used cars, 12 new trucks, and some used trucks at Bob's Auto Plaza. We are asked to find the probability that the chosen vehicle is used or is a car.

First, we need to find the total number of vehicles at the dealership:

Total number of vehicles = 10 new cars + 4 used cars + 12 new trucks + used trucks

We don't know how many used trucks there are, but we know that there are at least 4 of them (since there are 4 used cars). So the total number of vehicles is at least:

Total number of vehicles = 10 + 4 + 12 + 4 = 30

Now we need to find the number of vehicles that are used or cars. There are 4 used cars, and 10 new cars, for a total of 14 cars. There are also some used trucks, which we don't know the exact number of, but we know that there are at least 4 of them. So the total number of used or car vehicles is at least:

Total number of used or car vehicles = 4 used cars + 10 new cars + 4 used trucks = 18

To find the probability of choosing a used or car vehicle, we divide the number of used or car vehicles by the total number of vehicles:

Probability of choosing a used or car vehicle = Total number of used or car vehicles / Total number of vehicles

Probability of choosing a used or car vehicle = 18 / 30

Divide the numbers

Probability of choosing a used or car vehicle = 0.6

Answer:

The height would be 10.5 cm

Answer:

hb=10.5cm

Step-by-step explanation:

Area of triangle = 1/2(height x base)

The problem states that base is 8 cm greater than the height; therefore, base-8 = height.

A = 1/2(b*h)

42 = 1/2(b*[b-8])

84=(b^2-8b)

rearrange to

b^2 - 8b -84

factor to

(b+8)(b-14)

Therefore, b = -8 cm which makes no sense and

b = +14 cm

and height = 14-8 = 6

Check:

1/2(b*h) = area

1/2(14*6) = 1/2(84)=42

c.) a text poll provided during a nightly news broadcast

Step-by-step explanation:

Correct on Edge for Statistics class

The option C. a text poll provided during a nightly news broadcast is a method which would provide a voluntary response sample.

Sampling methods are the methods used to select a random sample from a big population.

Common methods of selecting samples are voluntary response sample, convenience sample, simple random sample, stratified random sample, cluster random sample and systematic random sample.

In voluntary response sample, sample is selected by putting a request for the population members to join the sample. It is the people who are the members of the population decide to join the sample or not.

In the option A, a survey of adults leaving a movie theater, people does not have an option to join or not. All the adults are joining for the sample which is not a voluntary response sample.

In the option B, all students are being surveyed, which is also not a voluntary response sample.

In the option C, people are deciding whether to poll or not which is a voluntary response sample.

In the option D, survey includes all the 10th people leaving the shopping mall, which is also not voluntary response sample.

Hence the method which would provide voluntary response sample is a text poll provided during a nightly news broadcast.

Answer:

$3.05 i'm pretty sure

Step-by-step explanation:

If one pound is $0.94 and she bought 3.25 pounds you multiply 3 by 0.94 and get $2.82 (we multiply by 3 to make it easier and to deal with the .25 later) then now we deal with the .25, since .25 is 1/4 in fraction just find out what 1/4 of .94 is which is .23 cents. So add $2.82 and $0.23 and you get $3.05

The one function that satisfies f '(x) = 3x² + 6x + 5 is f(x) = x³ + 3x²÷2 + 5x + C. where C is the constant of integration.

The given function's derivative is f'(x) = 3x² + 6x + 5.

To find the original function f(x), we need to integrate the derivative.

We can integrate the given function f'(x) term by term, using the power rule of integration:

∫f'(x) dx = ∫(3x² + 6x + 5) dx

f(x) = x^3 + 3x²÷2 + 5x + C

Any constant value of C can be added to the above function, resulting in an infinite number of functions that satisfy

f '(x) = 3x² + 6x + 5.

f(x) = x^3 + 3x²÷2 + 5x + 2 and f(x) = x³ + 3x²÷2 + 5x - 7 are both valid solutions to f '(x) = 3x² + 6x + 5, with different constant values of C.

This is because the constant of integration represents an arbitrary constant, and when we take the derivative, the constant term becomes zero. Hence, any function that differs from the original function by a constant value will also have the same derivative.

By solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

A mathematical statement known as an equation is made up of two expressions joined by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the number of the variable x is 7.

So, calculate as follows:

Let g represent giraffes and o represent ostriches.

g + o = 70 ...(1)

4*g + 2*o = 200  ...(2)

g = 70 - o, according to equation 1, therefore we may enter that number in place of g in equation 2 to obtain:

4*g + 2*o = 200

4*(70-o) + 2*o = 200

280 - 4o + 2o = 200

-2o = 200 - 280

2o = 80

o = 80/2

o = 40

Ostriches are 40 then giraffes will be:

70 - 40 = 30

Therefore, by solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

The length of the rectangle is 7 cm and the width is 5 cm.

The whole distance covered by the rectangle's borders or its sides is known as its perimeter. As we know the rectangle will have 4 sides then the perimeter of the rectangle will be equal to the total of its four sides. And the unit will be in meters, centimeters, inches, feet, etc.        

The formula for the Perimeter of the rectangle is given by

Here we have

The length of a rectangle is 2cm greater than the width of the rectangle

And perimeter of the rectangle = 24 cm

Let x be the width of the rectangle

From the given data,

Length of the rectangle = (x + 2) cm  

As we know Perimeter of rectangle = 2(Length+width)

=> Perimeter of rectangle = 2(x+2 + x) = 2(2x +2)

From the given data,

Perimeter of rectangle =  24cm

=> 2(2x +2) = 24 cm

=> (2x +2) = 12     [ Divided by 2 into both sides ]

=>  2x = 12 - 2

The minimum score required for admission to the university is 3.6.

To find the minimum score required for admission to the university, we need to determine the GRE score that corresponds to the 40th percentile of the distribution.

First, we need to find the z-score that corresponds to the 40th percentile. We can use a standard normal distribution table or a calculator to find this value.

Using a standard normal distribution table, we can look up the z-score that corresponds to a cumulative area of 0.40, which is approximately 0.25.

The z-score corresponding to a cumulative area of 0.25 is -0.25.

Next, we can use the formula for transforming a z-score to a raw score:

z = (x - mu) / sigma

where:

z is the z-score (-0.25 in this case)

x is the raw score we want to find

mu is the mean of the distribution (3.8 in this case)

sigma is the standard deviation of the distribution (0.8 in this case)

Solving for x, we get:

\(x = z\times sigma + \mu\)

\(x = (-0.25)\times 0.8 + 3.8\)

x = 3.6.
