According to the Question :-

\(:\implies\) 460 = x + y ( Profit)

\(:\implies\) 400 = x - y ( Loss)

Adding both :-

\(:\implies\) 460 + 400 = x + y + x - y

\(:\implies\) 860 = 2x

\(:\implies\) x = 860/2

\(:\implies\) x = 430

Hence the Cost price of the watch is 430 .

Answer:

x = 8

Step-by-step explanation:

The measure of an arc is equal to the angle at the centre subtended by the arc.

The sum of the 3 arcs = 180° , then

5x + 6 + 83 + 51 = 180

5x + 140 = 180 ( subtract 140 from both sides )

5x = 40 ( divide both sides by 5 )

x = 8

The faster train overtake the slower on 5 p.m.

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed x Time.

Let the number of hours after 1pm at which faster train will overtake slower train be x.

At overtaking point,

Distance travelled by slower train = Distance travelled by faster train

Given :

On equating distances we get

40 x ( x + 20) = 60 x (x)

40x + 80 = 60x

20x = 80

x = 4.

∴The faster train overtake the slower on 1 + 4 = 5 p.m.

Answer: 110 degrees

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees, so the third angle is 180-40-30=110 degrees.

The vector notation <4, -5> is the same as writing \((x,y) \to (x+4, y-5)\) which in my opinion is more descriptive in saying "4 units to the right, 5 units down"

We shift 4 units to the right because of the x+4. Whatever x is, add 4 to it getting x+4. So for instance x = 10 leads to x+4 = 10+4 = 14.

The y-5 is why we shift 5 units down. Eg: y = 37 leads to y-5 = 37-5 = 32.

Answer:

\(6 \times 7 = 42\)

The solution of the limits are

1. f(x) = {(1/x-1) if x<1; (x³-2x+5) if x>=1 is does not exist

2. f(x) = {(3-x) if x<2; 2 if x = 2; x/2 if x>2 is 1

3. f(x) = {1-x^2 if x<1; 2 if x>=1 is does not exitst

4. f(x) = {(2x+1) if x<=-1; 3x if -1=1 is 1

5. f(x) = {(x-1)^2 if x<0; (x+1)^2 if x>=0 is 0

f(x) = {(1/x-1) if x<1; (x³-2x+5) if x>=1 is 1

To evaluate this function, we need to determine the limit of the function as x approaches 1 from both the left and the right sides.

When x approaches 1 from the left side (x<1), the function becomes f(x) = 1/(x-1). As x gets closer to 1 from the left side, the denominator (x-1) becomes smaller and smaller, causing the entire fraction to approach infinity. Therefore, the limit of f(x) as x approaches 1 from the left side is infinity.

When x approaches 1 from the right side (x>=1), the function becomes f(x) = x³-2x+5. As x gets closer to 1 from the right side, the function approaches 4. Therefore, the limit of f(x) as x approaches 1 from the right side is 4.

Since the limit of the function from the left and right sides are different, the limit of the function as x approaches 1 does not exist.

f(x) = {(3-x) if x<2; 2 if x = 2; x/2 if x>2

To evaluate this function, we need to determine the limit of the function as x approaches 2 from both the left and the right sides.

When x approaches 2 from the left side (x<2), the function becomes f(x) = 3-x. As x gets closer to 2 from the left side, the function approaches 1. Therefore, the limit of f(x) as x approaches 2 from the left side is 1.

When x approaches 2 from the right side (x>2), the function becomes f(x) = x/2. As x gets closer to 2 from the right side, the function approaches 1. Therefore, the limit of f(x) as x approaches 2 from the right side is 1.

Since the limit of the function from the left and right sides are the same, the limit of the function as x approaches 2 exists and is equal to 1.

f(x) = {1-x² if x<1; 2 if x>=1

To evaluate this function, we need to determine the limit of the function as x approaches 1 from both the left and the right sides.

When x approaches 1 from the left side (x<1), the function becomes f(x) = 1-x². As x gets closer to 1 from the left side, the function approaches 0. Therefore, the limit of f(x) as x approaches 1 from the left side is 0.

When x approaches 1 from the right side (x>=1), the function becomes f(x) = 2. As x gets closer to 1 from the right side, the function remains constant at 2. Therefore, the limit of f(x) as x approaches 1 from the right side is 2.

Since the limit of the function from the left and right sides are different, the limit of the function as x approaches 1 does not exist.

f(x) = {(2x+1) if x<=-1; 3x if -1=1

To evaluate this function, we need to determine the limit of the function as x approaches -1 from both the left and the right sides.

When x approaches -1 from the left side (x<-1), the function becomes f(x) = 2x+1. As x gets closer to -1 from the left side, the function approaches -1. Therefore, the limit of f(x) as x approaches -1 from the left side is -1.

When x approaches -1 from the right side (-1<x<1), the function becomes f(x) = 3x. As x gets closer to -1 from the right side, the function approaches -3. Therefore, the limit of f(x) as x approaches -1 from the right side is -3.

Since the limit of the function from the left and right sides are different, the limit of the function as x approaches -1 does not exist.

f(x) = {(x-1)² if x<0; (x+1)² if x>=0

To evaluate this function, we need to determine the limit of the function as x approaches 0 from both the left and the right sides.

When x approaches 0 from the left side (x<0), the function becomes f(x) = (x-1)². As x gets closer to 0 from the left side, the function approaches 1. Therefore, the limit of f(x) as x approaches 0 from the left side is 1.

When x approaches 0 from the right side (x>=0), the function becomes f(x) = (x+1)². As x gets closer to 0 from the right side, the function approaches 1. Therefore, the limit of f(x) as x approaches 0 from the right side is 1.

Since the limit of the function from the left and right sides are the same, the limit of the function as x approaches 0 exists and is equal to 1.

Answer:

\(\displaystyle{P(x)=x^3-x^2}\)

Step-by-step explanation:

Given the zeros of 0, 0, 1. We can write the polynomial in form of x-intersects:

\(\displaystyle{P(x) = (x-x_1)(x-x_2)(x-x_3)}\)

Hence:

\(\displaystyle{P(x)=(x-0)(x-0)(x-1)}\)

Which can be simplified to:

\(\displaystyle{P(x)=x\cdot x \cdot (x-1)}\\\\\displaystyle{P(x)=x^2(x-1)}\)

Convert to the standard form by distributing x²:

\(\displaystyle{P(x)=x^2\cdot x - x^2 \cdot 1}\\\\\displaystyle{P(x)=x^3-x^2}\)

In inferential statistics, we calculate statistics of sample data to estimate the characteristics of the entire population from which the sample was taken. The process involves drawing inferences about a population from a random sample of data taken from that population.

The sample statistics are used to estimate the parameters of the population. To make an inference, we use a hypothesis test or confidence interval based on the sample statistics. The key to inferential statistics is random sampling, which allows us to make generalizations about the population based on the characteristics of the sample.

In order to ensure that the sample is representative of the population, we use a variety of sampling techniques, including simple random sampling, stratified sampling, cluster sampling, and systematic sampling.

Each of these techniques has its own advantages and disadvantages, and the choice of technique depends on the characteristics of the population being studied and the research questions being asked.

Once we have a representative sample, we use statistical methods to draw conclusions about the population. This allows us to make predictions and to test hypotheses about the population with a high degree of confidence.

hope this is right :)

To find the general solution of the given higher-order differential equation y''' − 6y'' − 7y' = 0, we first need to find the characteristic equation by assuming that y = e^(rt), where r is a constant. Substituting this into the differential equation, we get r^3 - 6r^2 - 7r = 0.

Factoring this, we get r(r - 7)(r + 1) = 0. So the roots of the characteristic equation are r1 = 0, r2 = 7, and r3 = -1.

Therefore, the general solution of the differential equation is y(t) = c1 + c2e^(7t) + c3e^(-t), where c1, c2, and c3 are constants that can be determined using initial or boundary conditions.

In summary, the general solution of the given higher-order differential equation y''' − 6y'' − 7y' = 0 is y(t) = c1 + c2e^(7t) + c3e^(-t), where c1, c2, and c3 are constants.

Stem-and-leaf plots contain original data values where histograms do not. Therefore, option B is the correct answer.

The "stem" values are listed down, and the "leaf" values go right (or left) from the stem values.

The "stem" is used to group the scores and each "leaf" shows the individual scores within each group.

The advantage of a stem leaf diagram is it gives a concise representation of data. The advantage of a frequency histogram is, that it is visually strong. Histograms are usually preferable to stem and leaf diagrams in large data sets. The disadvantage of a stem leaf diagram is not visual.

The given statement is True for the scoring rule in bowling.

Scoring Rule in Bowling

The number of frames in a game of bowling is ten. According to the scoring rule in bowling, the bowler will have two opportunities to use their bowling ball to remove as many pins as they can throughout each frame.

Every bowler will complete their frame in a predefined order before the next frame starts in games with more than one bowler, which is typical.

Rule for Spare

A bowler is given a strike if they can remove all 10 pins with their first ball. A spare is achieved when the bowler uses both of the two balls in a frame to remove all 10 pins.

Depending on whether the next two balls (for a strike) or the next ball (for a goal) are scored, bonus points are given for both of these (for a spare), as per the scoring rule.
