Step-by-step explanation:

The marked price of the radio is Rs 10000.

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

Discount = 10%

VAT = 13%

VAT - Selling price = 1170

Represent the price of the radio with x

Using the above as a guide, we have the following:

Discount = 10% implies 0.9x

VAT = 13% implies 0.9x * 1.13 = 1.017x

So, the difference is

1.017x - 0.9x = 1170

This gives

0.117x = 1170

Divide

x = 10000

Hence, the price of the radio is Rs 10000.

Answer:

Step-by-step explanation:

The lines are neither parallel nor perpendicular.

Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if the product of their slopes is -1.

To find the slope of a line given in the form of Ax + By = C, we can rearrange the equation into slope-intercept form (y = mx + b), where m is the slope.

The first line, 6x - 12y = 24, can be rearranged into slope-intercept form as follows:

12y = -6x + 24

y = -0.5x + 2

The slope of the first line is -0.5.

The second line, 4x + 2y = 8, can be rearranged into slope-intercept form as follows:

2y = -4x + 8

y = -2x + 4

The slope of the second line is -2.

Since the product of the slopes is not -1, the lines are not perpendicular. And since the slopes are not the same, the lines are not parallel. So, the lines are neither parallel nor perpendicular.

A one-sample t-test should not be carried out in this setting because the data is in the form of a frequency distribution and is not continuous, and the distribution is not normal.

In statistics, a one-sample t-test is used to determine whether a sample mean is significantly different from a known population mean. However, in this scenario, the data collected and analyzed is in the form of a frequency distribution, where the percent of purchases for which an alternative supplier offered a lower price was recorded.

A frequency distribution shows the number of times a particular value or range of values occurs in a dataset. In this case, the frequency distribution shows the number of invoices that had a certain percentage of purchases for which an alternative supplier offered a lower price. This type of data is not suitable for a one-sample t-test because a t-test requires continuous data, which is not the case here.

Furthermore, a one-sample t-test assumes that the data is normally distributed. A histogram of the data in this scenario shows that the distribution is not symmetrical and does not resemble a normal distribution. Therefore, carrying out a t-test would not be appropriate.

5 additional trees give maximum yield and 35 trees per acre will give largest crop of apple.

Let's assume that, we are planting x apple trees extra per acre. So, net 10x apple will be less.

Let say, total number of apples = y

Then, y = (30+x)×(400–10x)

For, optimum number of trees, let's do the differentiation of the above equation with respect to x.

d(y)/d(x) = (400–10x)×1 + (30+x)×(-10)

= 400–10x-300–10x

= 100–20x …………..(1)

For mimima or maxima, the above equation must be equal to 0.

So, 0 = 100–20x

=> x=5

Let's do the second differentiation of equation (1) and substitute the the value of x I.e x=5

[tex]d^2(y)/d(x^2) = -20[/tex]

The above equation is negative for all values of x which indicates that at x=5 we will have the maximum value.

So, the number of trees for maximum apple will be (30+x)

So, 30+5 = 35 trees per acre will give the largest crop of apple.

Hence 5 additional trees give maximum yield and 35 trees per acre will give largest crop of apple.

At 12 noon the count in a bacteria culture was 400, at 3:00 pm the count was 1200. The bacteria count at 9 am, rounded off to the nearest bacterium, was 255.

The problem involves finding the bacteria count at 9 am, given the counts at 12 noon and 3 pm, and assuming that the bacteria culture obeys the population growth law.

To solve the problem, we use the population growth law, which states that the rate of growth of a population is proportional to the size of the population at any given time. This can be expressed as a differential equation, and its solution gives the population as a function of time.

Assuming the bacteria culture grows exponentially between 9 am and 3 pm, we can use the population growth law to find the bacteria count at 9 am. Let the initial count at 9 am be denoted by P, and let the growth rate be denoted by r.

Then we have:

P * (1 + r)^3 = 1200

Solving for P, we get:

P = 1200 / (1 + r)^3

Similarly, assuming the bacteria culture grows exponentially between 12 noon and 3 pm, we have:

400 * (1 + r)^3 = 1200

Solving for r, we get:

r = (1200/400)^(1/3) - 1

Plugging this value of r into the equation for P, we get:

P = 1200 / (1 + (1200/400)^(1/3) - 1)^3

Using a calculator, we get:

P ≈ 255

Here is the answer

In the function rule p(t) - 700, the number 700 represents a constant value that is subtracted from the value of the function p(t).

Assuming that p(t) is a function of time t, it is possible that p(t) represents a physical quantity such as the population of a city, the price of a stock, or the number of customers in a store, among other things. If we know what p(t) represents, we can interpret the meaning of 700 in the context of the situation.

For example, if p(t) represents the population of a city, then p(t) - 700 would represent the difference between the population and a reference value of 700. This could mean that 700 is the estimated minimum viable population of the city, or it could represent a reference population for comparison with other cities.

If p(t) represents the price of a stock, then p(t) - 700 would represent the difference between the stock price and a target value of 700, such as a price floor or a strike price.

In general, the meaning of 700 in the function rule p(t) - 700 depends on the specific context of the situation and the physical quantity that p(t) represents.

Answer:

8π

Step-by-step explanation:

The period of a function f(x)  is the x-distance between two repeating points of the function

Looking at the function graph given we see that the function reaches a peak value(called amplitude) at x = -6π and then again reaches this value at x = 2π

So the x-distance is 2π - (-6π) = 2π + 6π = 8π

From 2π, the function reaches its maximum value again at 10π giving the period once again as 10π - 2π = 8π

The area of the figure is 254.8 m²

Area is the region occupied by an object.

Since the figure is a rectangle and containing two semi-circles, we find the area of the figure by finding the area of the rectangle and the two semi-circles.

The area of the rectangle is given by A = LW where

Given that

A = LW

= 16 m × 12 m

= 192 m²

The area of a semi-circle with diameter d is A = πd²/4

Now for the first semi-circle, its diameter d' = 8 m.

So, its area A' =  πd'²/4

=  π(8 m)²/4

= π64 m²/4

= 16π m²

= 16 ×3.14 m²

= 50.24 m²

Also, for the fsecond semi-circle, its diameter d" = 4 m.

So, its area A' =  πd'²/4

=  π(4 m)²/4

= π16 m²/4

= 4π m²

= 4 × 3.14 m²

= 12.56 m²

So, the area of the figure is A₁ = A + A' + A"

= 192 m² + 50.24 m² + 12.56 m²

Answer:

A.  9.4 mi

Step-by-step explanation:

Sketch a right triangle with legs of 8 and 5.  Shortest distance back to the starting point is the hypotenuse (h) of the triangle:

h² = 8² + 5² = 89

h = √89 = 9.43 mi

Let's call the width of the rectangle "w".

According to the problem, the length of the rectangle is 12 meters more than 5 times the width, so we can write that as:

L = 5w + 12

And the area is given as 32 square meters, so we can write that as:

A = L * w = 32

Now we have two equations:

5w + 12 = L

L * w = 32

We can use the first equation to substitute the value of L in the second equation:

L = 5w + 12

32 = (5w + 12) * w = 5w^2 + 12w

Expanding the right side of the equation, we get:

32 = 5w^2 + 12w

Now we have a quadratic equation that we can solve for w. To do this, we can use the quadratic formula:

w = (-b ± √(b^2 - 4ac)) / 2a

where a = 5, b = 12, and c = -32. Plugging in these values, we get:

w = (-12 ± √(12^2 - 4 * 5 * -32)) / (2 * 5)

w = (-12 ± √(144 + 640)) / 10

w = (-12 ± √(784)) / 10

w = (-12 ± 28) / 10

w = (16 / 10) or ( -40 / 10)

w = 1.6 or -4

Since the width cannot be negative, the width must be 1.6 meters.

The equation of the quadratic equation whose root are 5 and -9 is x² +4x -45

quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0 . Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The range of 85-95 is within one standard deviation of the mean in a normal distribution with a mean of 90 and a standard deviation of 5,the correct answer is c. 85-95.

The normal distribution is a bell-shaped curve that is centered around the mean and symmetrical about the mean. In a normal distribution with a mean of 90 and a standard deviation of 5, one standard deviation of the mean would be 85-95. This means that any score within this range is within one standard deviation of the mean.

To calculate this, we first look at the mean, which is 90. To find the value of one standard deviation from the mean, we need to subtract 5 from 90 to get 85. To find the upper limit of one standard deviation, we add 5 to 90 to get 95. Therefore, any score between 85 and 95 is within one standard deviation of the mean.

To summarize, any score within the range of 85-95 is within one standard deviation of the mean in a normal distribution with a mean of 90 and a standard deviation of 5. Therefore, the correct answer is c. 85-95.
