The value 750 in equation 300x + 750 = 23,250 represents the initial amount in the club account.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

Initial amount in the club account = m

Amount raised by each member = n

All members raised the same amount.

Number of members = x

The total amount raised by all the members = p

nx + m = p

This is similar to the equation 300x + 750 = 23,250

So,

n = 300

m = 750

p = 23,250

Now,

m = 750 is the initial amount in the club account.

Thus,

750 represents the initial amount in the club account.

Answer: Any number that is to the right of it, hence greater/bigger.

-8,-7,-6,-5.....

Step-by-step explanation:

Example: If you have -8 vs -9 vs -10 dollars, You have more with -8 vs -9 or -10.

Hence anything to the right of a give number on the number line is greater.

Also, think of the opposite with negatives.

For example with positive numbers, the larger the number the greater, but with negative numbers its the other way around, the smaller the number the greater.

Since the distribution of the 10 distances is not uniform, Raul should use the median to determine his total performance.

The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory.

It could be referred to as "the middle" value for a data set.

The fundamental difference between the mean and the median when describing data is that the median is more representative of the "normal" value because it is not skewed by a tiny fraction of exceptionally big or small values.

Due to the fact that income distribution can be very skewed, the median income, for instance, might be a better indicator of what is considered a "normal" income.

Given that it is the most resilient statistic, the median is crucial to strong statistics.

According to our question-

Step-by-step explanation:

Answer:

1. t*y

2. 365*t*y

Step-by-step explanation:

Identify variables

T (time) seconds

Y amount of times per day

T * Y = amount of time you would spend carrying water in a day, 24 hrs

365 * t * y = 365 (amount of days per year, multiplied by the amount of time you carry water per day.)

The present value of $5000 to be received in 2 years at a 12% interest rate compounded continuously is $6356.25. This can be calculated by using the formula PV = FV/(1 + r)^t, where PV is the present value, FV is the future value, r is the interest rate, and t is the time period. Therefore, PV = 5000/(1 + 0.12)^2 = $6356.25.

Note that the area of the above triangle is given as: 42.

This is solved using the SOH CAH TOA Rule and the Formula of the Right Angled Triangle

The hypotenuse is the longest side of a right triangle, a "opposite" side is the one across from a given angle, and a "adjacent" side is the one close to a given angle. Right triangle sides are described using specific terminology. A right triangle's hypotenuse is always the side opposite the right angle.

To find the area of the triangle we must obtain, the Base and the Height, that is FD and A F.

Note that we have

∠F = 90°

∠D = 30°

Since the sum of angles in a Δ = 180°,

∠A = 180 - (90 + 30)

∠A = 60°

To find the area of the triangle we must obtain, the Base and the Height, that is F D and A F.

To obtain F D, we must use the Sine rule which states:
Sine θ = O/H; that is

Sin ∠A = F D/AD

Sin 60° = F D/14

0.86602540378 = FD/14

F D = 14 * 0.86602540378

F D = 12.1243556529

F D [tex]\approx[/tex] 12. 12

Using the above Cos Rule (CAH) we can find the Adjacent Side (that is height). Thus

Cos A = A F/AD

Cos 60° = A F/14

0.5 = A F/14; multiply both sides by 14

A F = 0.5 * 14

A F = 7

Now we have Adjacent Side  (Height) = 7; and the Opposite Side (Base) = 12.12

The area of the Triangle according to the Pythagorean Rule is:

1/2 B * H

= 1/2 * 12.12 * 7

= 42.42

Thus the Area of the above triangle [tex]\approx[/tex] 42

The equation in slope-intercept form of the line that passes through the points is f(x) = 2x + 2

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

f(0) = 2 , f(-2) = -2

A linear equation can be represented as

f(x) = mx + c

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

m * 0 + c = 2

m * -2  + c = -2

Solving 0 * x + c = 2, we have

c = 2

So, we have

m * -2 + c = -2

This gives

-2 * m + 2 = -2

Evaluate the like terms in the above equation

So, we have the following representation

-2m = -4

Divide both sides of the equation by -2

So, we have

m = 2

Substitute the known values in the equation f(x) = mx + c, so, we have the following representation

f(x) = 2x + 2

Hence, the function is f(x) = 2x + 2

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right triangles. It is concerned with the measurement of angles and the calculation of sines, cosines, and tangents of those angles.

These ratios are known as trigonometric functions and they are used to relate the ratios of the sides of a right triangle to the angles opposite or adjacent to the right angle.

Since sin 30° = 0.5

Thus, sin⁻¹(0.5) = 30.00 degrees

A linear equation can be used to represent the situation where a fixed amount is added to the original balance each month. The equation would have the form:

y = mx + b

where x is the number of months, y is the balance in the bank account, m is the monthly deposit amount, and b is the initial balance. In this case, we have:

y = 60x + 575

This equation can be read as: "The balance in the bank account (y) is equal to 60 dollars (m) added to the account each month (x), plus the initial balance of 575 dollars (b)."

An exponential equation can also be used to represent the situation where the balance in the bank account increases by a fixed percent each month, it would be:

Where a is the initial amount, r is the interest rate and x is the number of months.

With sides that are 4 cm, 3 cm, and 7 cm long, a triangle cannot be built. Because the sum of the other two sides does not exceed that of the third side.

The triangle's three sides are specified as being 4 cm, 3 cm, and 7 cm. Add the two sides together and see if the result exceeds the third side to determine whether these sides constitute a triangle.

Here, the sum of two sides 4 cm and 3 cm is calculated as,

All these equations are having infinitely many solution.

Infinitely Many solution:

An equation can have an infinite number of solutions if certain conditions are met. If the lines are coincident and have the same y-intercept, the system of equations has infinitely many solutions. If two lines have the same y-intercept and slope, they are really on the same line.

(i) Given :

3x + 4y = 7                        --------------------------- (1)

On putting x = 0 in equation 1

3x + 4y = 7

⇒ 3 × 0 + 4y = 7

⇒ 0 + 4y = 7

⇒ 4y = 7

⇒ y = 7/4

Therefore, ( 0, 7/4) is a solution of given equation.

On putting y = 0 in equation 1

3x + 4 × 0 = 7

⇒ 3x + 0 = 7

⇒ 3x = 7

⇒ x = 7/3

Thus, (7/3, 0) is a solution of given equation.

Hence, 2 out of the infinitely many solutions of the given equation are(0,7/4), (7/3,0).

(ii) x = 6y

Let x = 0

⇒ x = 6y

⇒ 0 = 6y

⇒ y = 0/6

⇒ y = 0

(0,0) is the solution.

Let x = 1

⇒ x = 6y

⇒ 1 = 6y

⇒ y = 1/6

(1,1/6) is the solution.

Hence, 2 out of the infinitely many solutions of the given equation are (0,0), (1,1/6).

(iii) x + πy = 4

let x = 0

⇒ x + πy = 4

⇒ 0 +  πy = 4

⇒ πy = 4

⇒ y = 4/π

(0, 4/π) is the solution.

Let y = 0

⇒ x + πy = 4

⇒ x + 0(y) = 4

⇒ x  + 0 = 4

⇒ x = 4

(4, 0) is the solution.

Hence, 4 out of the infinitely many solutions of the given equation are (0, 4/π), (4, 0).

(iv) x - y = 4

Let x = 0

⇒ x - y = 4

⇒ 0 - y = 4

⇒ -y = 4

⇒ y = - 4

(0,- 4) is the solution.

Let x = 1

⇒ x - y = 4

⇒ 1 - y = 4

⇒ -y = 4 - 1

⇒ -y = 3

⇒ y = - 3

(1,- 3) is the solution.
