When the point (1, 3) is substituted in the equation y = ax, then 'a' i,e slope of the line is 3

If a line passes through the origin, its equation can be written in the form y = mx, where m is the slope of the line.

The slope of a line passing through the origin is the ratio of the change in y to the change in x between any two points on the line.

Here we have  

A line passes through the origin, the equation is in the form y = ax

Given that y = ax passes throgh (1, 3)

So substitute x = 1 and y = 3

=> 3 = a(1)

=> a = 3/1

=> a = 3  

Therefore,

∫fx(x)dx = 1 over the entire range of x, and fx is indeed a density function.

A random variable X has the normal distribution N(m, o^2), where m and o are both real numbers, if it is an absolutely continuous random variable with density fx(x) = (1/√(2πo^2)) * exp(-(x-m)^2/2o^2).

To verify that fx is indeed a density, we need to check that it satisfies the two properties of a density function:

1) fx(x) >= 0 for all x
2) ∫fx(x)dx = 1 over the entire range of x

First, let's check that fx(x) >= 0 for all x. Since the exponential function is always positive, we can see that fx(x) will always be positive as well. Therefore, fx(x) >= 0 for all x.

Next, let's check that ∫fx(x)dx = 1 over the entire range of x. To do this, we need to integrate fx(x) over the entire range of x, which is from -∞ to ∞:

∫fx(x)dx = ∫(1/√(2πo^2)) * exp(-(x-m)^2/2o^2)dx from -∞ to ∞

Using the substitution u = (x-m)/√(2o^2), we can rewrite the integral as:

∫(1/√(2πo^2)) * exp(-u^2/2) * √(2o^2)du from -∞ to ∞

Simplifying, we get:

∫(1/√(2π)) * exp(-u^2/2)du from -∞ to ∞

This integral is equal to 1, as it is the integral of the standard normal density function. Therefore, ∫fx(x)dx = 1 over the entire range of x, and fx is indeed a density function.

On a roll of a number cube, the theoretical probability of the event of rolling a 8 is 0.

The Theoretical Probability is defined as the likelihood of an event occurring based on all possible outcomes in a given situation.

The theoretical probability is determined by dividing the number of ways the event can occur by the total number of possible outcomes.

The theoretical probability of rolling a specific number on a fair, six-sided number cube is 1/6, because there are 6 equally likely outcomes which are the numbers 1 to 6,

So, the theoretical probability of rolling an 8 on a number cube is 0 or 0%, because an 8 is not one of the possible outcomes when rolling a standard, six-sided number cube.

Therefore, the required probability is 0.

No, a linear equation that is equivalent to the equation 0=-7 is not a conditional equation. Instead, it is an inconsistent equation.
A conditional equation is an equation that is only true for certain values of the variable. For example, the equation 2x+3=7 is a conditional equation because it is only true when x=2.
An inconsistent equation, on the other hand, is an equation that has no solution. The equation 0=-7 is an example of an inconsistent equation because there is no value of x that will make the equation true.
Therefore, a linear equation that is equivalent to the equation 0=-7 is an inconsistent equation, not a conditional equation.

The inverse of a function, denoted f^-1(x), is a function that "undoes" the original function. In other words, if f(x) = y, then f^-1(y) = x.

To find the inverse of a function from a table of values, we simply switch the x and y values. So, for the given table of values:
x | 1 | 2 | 3 | 4 | 5 | 6
---|---|---|---|---|---|---
f(x) | 7 | 9 | 3 | 0 | 4 | 1
The inverse function f^-1(x) would have the table of values:

x | 7 | 9 | 3 | 0 | 4 | 1
---|---|---|---|---|---|---
f^-1(x) | 1 | 2 | 3 | 4 | 5 | 6
Now, to find f^-1(0), we simply look for the value of x that corresponds to f^-1(x) = 0. From the table, we can see that f^-1(0) = 4.

Therefore, the answer is f^-1(0) = 4.

To check if an ordered pair is a solution of a system of equations, we can plug the values of the ordered pair into the equations and see if they are true.

For the first equation, x + y = 11, we can plug in 5 for x and 6 for y:

5 + 6 = 11

This is true, so the ordered pair satisfies the first equation.

For the second equation, x - y = -1, we can again plug in 5 for x and 6 for y:

5 - 6 = -1

This is also true, so the ordered pair satisfies the second equation.

Since the ordered pair satisfies both equations, it is a solution of the system of equations.

The x-coordinate of the midpoint of line segment AB is 29.5

What is coordinate?

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.

To find the x-coordinate of the midpoint of line segment AB, we can use the midpoint formula:

Midpoint x-coordinate = (x-coordinate of A + x-coordinate of B) / 2

We are given the coordinates of points A and B:

A(13, 5) and B(46, -13)

Using the midpoint formula, we can substitute the x-coordinates of A and B into the formula and simplify:

Midpoint x-coordinate = (13 + 46) / 2

= 29.5

Therefore, the x-coordinate of the midpoint of line segment AB is 29.5

Answer:

Yes, the ratios 3:6 and 2:4 are equivalent because they represent the same proportion. To confirm, we can simplify both ratios to their simplest form:

3:6 can be simplified by dividing both terms by 3: 3/3 : 6/3 -> 1:2

2:4 can be simplified by dividing both terms by 2: 2/2 : 4/2 -> 1:2

Since both ratios simplify to the same ratio, 1:2, they are equivalent.

Answer: yes !!

Step-by-step explanation: 3:6 and 2:4 are equivalent b/c of their common factors.

The given statement "When simplifying the expression 5-8+2, the first step would be to add eight and two" is false because of the PEMDAS rule.

According to the order of operations (PEMDAS), we need to perform any calculations inside parentheses first, then exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right.

In this case, there are no parentheses or exponents, so we can move on to addition and subtraction from left to right.

The first step would actually be to subtract 8 from 5, giving us -3. Then we would add 2 to -3, giving us a final answer of -1.

The triangle solved  using the Law of Sines. D=10,∠A=30 4, and, C=120 4 where a = 5.77 c = 10 i = 30°

To solve the triangle, we need to use the formula:
a/sinA = b/sinB = c/sinC

Given that D=10, ∠A=30°, and C=120°, we can plug in these values into the formula and solve for the unknown sides:

a/sin30° = 10/sin120°

Cross-multiplying and solving for a gives us:

a = 10*sin30°/sin120°

a = 5.77

Similarly, we can solve for the other unknown side, c:

c/sinC = 10/sin120°

c = 10*sinC/sin120°

c = 10*sin120°/sin120°

c = 10

Finally, we can solve for the unknown angle, i, using the fact that the sum of the angles in a triangle is 180°:

i = 180° - 30° - 120°

i = 30°

Therefore, the solution to the triangle is:

a = 5.77

50 % of the total books are of Marathi = x*50/100 = x/2

Books of English are 1/3rd of Marathi = (x/2)*(1/3)

                                                              = x/6

Books on Mathematics are 25 % of the English books = (x/6)*(25/100)

                                                                                          = x/24

Remaining books = 560

Now, according to the question.

⇒ x/2 + x/6 + x/24 + 560/1 = x/1

⇒ (12x + 4x + x + 13440)/24 = x/1

⇒ 17x + 13440 = 24x
