Answer:

98÷7=14 cuz 14×7=98

Step-by-step explanation:

The slope of the line c is - 92.

The points via which the line b passes are:

(-20, 4) and (-21, 96).

The slope of the line is given by:

m = (y₂ - y₁) / (x₂ - x₁)

Slope of the line b passing through these points are:

m = (96 - 4) / (- 21 + 20)

m = (92) / (-1)

m = - 92

Since, line b is parallel to line c,

Slope of line b = slope of line c

So, the slope of line c is also:

m' = - 92

Therefore, we get that, the slope of the line c is - 92.

Answer:

Simple Interest for 1 year = 40/2 = 20

CI for 2 years = 20 + 20 + 1

The difference of Re 1 is due to the interest received on this interest.

Hence interest rate = 1/20 * 100 = 5

Interest for 1 year at 5% = 20

Hence principal = 20*100/5 = 400

The Linnaean class system provides a framework for understanding the diversity of life on Earth by grouping similar organisms together based on shared characteristics.

By comparing and contrasting the definitions of each class, we can see how different groups of animals are related to each other and how they differ in terms of their biological traits.

The Linnaean class system is a way of organizing living things based on shared characteristics. Let's compare and contrast the definitions of the Linnaean classes using a Venn diagram.

First, we have the class Mammalia, which includes all animals that have hair or fur, produce milk to feed their young, and have specialized teeth. This class overlaps with the class Aves, which includes all birds, because some birds have specialized beaks and feathers that are similar to mammalian hair and teeth. However, birds do not produce milk.

Next, we have the class Reptilia, which includes animals that are cold-blooded, lay eggs, and have scales or plates on their skin. This class overlaps with both Mammalia and Aves in terms of species that lay eggs, such as monotremes (platypus and echidnas) and some birds (ostriches and emus). However, reptiles lack specialized teeth and do not produce milk.

Finally, we have the class Amphibia, which includes animals that are cold-blooded, breathe through their skin, and undergo metamorphosis from a water-dwelling larval stage to a land-dwelling adult stage. This class overlaps with Reptilia in terms of some shared characteristics, but Amphibia also lacks specialized teeth and does not lay eggs with hard shells like reptiles.

Yes, if the mean weight of two groups of children is different with a p-value of 0.03, the difference is statistically significant. Typically, a p-value of less than 0.05 is considered statistically significant, indicating that the observed difference is unlikely to be due to chance alone.

Yes, if the p level is .03, then the difference in mean weight between the two groups of children is statistically significant. The p level that identifies statistical significance is generally considered to be .05 or less, meaning that there is a 5% or less chance that the difference observed is due to random chance rather than a true difference between the two groups. Therefore, a p level of .03 is below the commonly accepted threshold for statistical significance and suggests that the difference in mean weight is not likely due to chance alone.

a) The function gof is gof(x) = 3x + 3.

b) The function gof: RR is well-defined.

a. The value of function gof(x) = 3x + 3.

To find the composition gof, we substitute the expression for g into f:

gof(x) = f(g(x))

= f(x + 1)

= 3(x + 1)

= 3x + 3

b. To prove that gof is both one-to-one and onto, we need to show the following:

(i) One-to-one: For any two different inputs x1 and x2, if gof(x1) = gof(x2), then x1 = x2.

(ii) Onto: For every y in the range of gof, there exists an x such that gof(x) = y.

Proof of one-to-one:

Let x1 and x2 be two different inputs. Assume that gof(x1) = gof(x2).

Then, 3x1 + 3 = 3x2 + 3.

Subtracting 3 from both sides, we have 3x1 = 3x2.

Dividing both sides by 3, we obtain x1 = x2.

Therefore, gof is one-to-one.

Proof of onto:

Let y be any real number in the range of gof, which is the set of all real numbers.

We need to find an x such that gof(x) = y.

Consider the equation 3x + 3 = y.

Subtracting 3 from both sides, we have 3x = y - 3.

Dividing both sides by 3, we obtain x = (y - 3)/3.

Thus, for any y in the range of gof, we can find an x such that gof(x) = y.

Therefore, gof is onto.

Since gof is both one-to-one and onto, it is a bijection.

Alessia spent $5,408 on entertainment in 2021.

To determine how much Alessia spent on entertainment in 2021, we need to work backward from the given information about her salary in 2022.

Let's assume Alessia's salary in 2021 was the same as in 2022, which is $26,000 after tax.

Since Alessia spends 35% of her after-tax salary on rent, we can calculate her rent expenditure:

Rent = 35% × $26,000

= $9,100

The remaining amount is split between food, petrol, and entertainment in the ratio 6:11:8.

To determine the ratio's total parts, we sum the individual parts:

Total parts = 6 + 11 + 8 = 25

Next, we calculate the value of one part of the ratio:

One part = ($26,000 - $9,100) / 25

= $16,900 / 25

= $676

Now, we can calculate how much Alessia spent on entertainment in 2021, which is 8 parts of the ratio:

Entertainment expenditure = 8 × $676

= $5,408

Therefore, they have sold approximately 708 children's tickets (option C) when rounded to the nearest integer.

Let's assume the number of adult tickets sold as 'x'. Since they have sold 4 times as many children's tickets as adult tickets, the number of children's tickets sold would be 4x.

According to the given information, the total number of tickets sold is 885. Therefore, we can set up the equation:

x + 4x = 885

Combining like terms, we have:

5x = 885

Dividing both sides by 5, we get:

x = 885 / 5

x = 177

So, the number of adult tickets sold is 177.

Now, to find the number of children's tickets sold, we multiply the number of adult tickets by 4:

4x = 4 * 177

For the given signal \(x(t) = 4\sin(40\pi t) + 2\sin(100\pi t) + \sin(200\pi t)\), we are asked to plot the time-domain signal \(x(t)\) and the magnitude spectrum of its Fourier transform \(X(\omega)\).

To plot the time-domain signal \(x(t)\), we can calculate the values of the signal for different time instances and plot them on a graph. Since the signal is a sum of sinusoidal components with different frequencies, the plot will show the variations of the signal over time. The amplitude of each sinusoidal component determines the height of the corresponding waveform in the plot.

To plot the magnitude spectrum of the Fourier transform \(X(\omega)\), we need to calculate the Fourier transform of \(x(t)\). The Fourier transform will provide us with the frequency content of the signal. The magnitude spectrum plot will show the amplitude of each frequency component present in the signal. The height of each peak in the plot corresponds to the magnitude of the corresponding frequency component.

By plotting both \(x(t)\) and the magnitude spectrum of \(X(\omega)\), we can visually analyze the signal in both the time domain and the frequency domain. The time-domain plot represents the signal's behavior over time, while the magnitude spectrum plot reveals the frequency components and their amplitudes. This allows us to understand the signal's characteristics and frequency content.

The surface area of a square pyramid net can be found by adding the areas of the base and the four triangular faces.

First, find the area of the base by multiplying the length and width of the square base.

Area of base = length × width

Next, find the area of one of the triangular faces by using the formula:

Area of triangle = 0.5 × base × height

Since there are four triangular faces in a square pyramid, multiply the area of one triangle by four to find the total area of the triangular faces.

Area of triangular faces = 4 × (0.5 × base × height)

Finally, add the area of the base and the area of the triangular faces to find the total surface area of the square pyramid net.

Surface area = Area of base + Area of triangular faces

= (length × width) + (4 × (0.5 × base × height))

= (length × width) + (2 × base × height)

So, the surface area of a square pyramid net is the sum of the area of the base and the area of the four triangular faces.

Answer:

Step-by-step explanation:

The height of the Eiffel Tower was halved repeatedly to make a model around 30 cm. We know that 30 cm = 0.3 meters.

We can set up an equation:

324m / 2^n = 0.3m

We can solve for n by logarithm base 2:

n = log(324/0.3) / log(2)

n = log(1080) / log(2)

n ≈ 10.6

The height of the Eiffel Tower was divided by 2^10.6, which is not a whole number.

It means that the height of Eiffel Tower was divided by a number that is between 10 and 11 times by 2.
