The process of finding the value of a numerical or algebraic expression is called evaluation.

Evaluation involves substituting the given values of the variables in the expression and then simplifying the expression using the order of operations (PEMDAS).

For example, if we are asked to evaluate the expression 3x + 2y when x=4 and y=5, we would substitute these values to get 3(4) + 2(5), which simplifies to 12 + 10 = 22. Therefore, the value of the expression 3x + 2y when x=4 and y=5 is 22.

In algebra, evaluation is an important process because it allows us to find the value of an expression for specific values of the variables, which can help us to solve equations or inequalities, and to simplify expressions.

Answer:

To find the quarterly rate of population increase, we first need to find the annual rate of population increase in decimal form, which is 2.8% expressed as 0.028.

To find the quarterly rate, we need to divide the annual rate by 4, since there are 4 quarters in a year:

0.028 / 4 = 0.007

Therefore, the quarterly rate of population increase is 0.007 or 0.7%

Step-by-step explanation:

Answer:

-1 1/3

Step-by-step explanation:

The scale floor's perimeter is 34 inches.

To solve, we can set up fractions:

21/7 = 30/x

Cross multiply and you get:

21x = 210

Divide each side by 21:

x = 10

You can apply the following equation since you're attempting to determine the floor's perimeter:

2w + 2l = p

Substitute to solve:

2 ( width = 10 )

2 ( length = 7 )

2 (7) + 2 (10) = p

14 + 20 = p

34 = p

The two missing angles of the quadrilateral are 10.5° and 2.47°, calculated from the given angles of 232° and 86°, and a ratio of 4:17.

The angle sum of a quadrilateral is 360°. Therefore, we need to find the sum of the two missing angles.We can start by subtracting the two known angles from the total angle sum and then dividing the difference by the ratio given.

360° - 232° - 86° = 42°

To find the two missing angles, divide the sum by the ratio given.

42° ÷ 4:17

The find the measure of the first angle, divide 42° by 4:

The x-intercept and the y-intercept of the line 5x - 2y = 10 include the following ordered pairs:

x-intercept = (2, 0).

y-intercept = (0, -5).

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).

In Mathematics, the y-intercept is sometimes referred to as an initial value (base value) and the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

From the given information provided, the cube root of 12,167 by prime factorization method is approximately 23.

You can find the cube root of 12,167 using a calculator or by using the prime factorization method.

Using the prime factorization method, we can express 12,167 as the product of its prime factors:

12,167 = 19 × 641

Since the cube root of a product is equal to the product of the cube roots of the factors, we can find the cube root of 12,167 as follows:

∛12,167 = ∛(19 × 641)

∛12,167 = ∛19 × ∛641

∛12,167 = 2.7144 × 8.0186

∛12,167 = 23.1649 (rounded to four decimal places)

Therefore, the cube root of 12,167 is approximately 23.

The probability P(red pen, purple pen) without replacement is 10/33.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that a container holds 5 red pens, 4 purple pens and 3 blue pens.

We need to find the probability P(red pen, purple pen) without replacement.

P(red pen, purple pen) = (number of ways to select a red pen and a purple pen) / (total number of ways to select two pens)

Total number of ways to select two pens=¹²C₂=66 ways.

Number of ways to select a red pen and a purple pen = (number of ways to select a red pen) x (number of ways to select a purple pen from the remaining pens)

Number of ways to select a red pen = 5

Number of ways to select a purple pen from the remaining pens = 4

Therefore, the number of ways to select a red pen and a purple pen without replacement is:

Number of ways to select a red pen and a purple pen = 5 x 4 = 20

P(red pen, purple pen) =20/66

=10/33

Hence, the probability P(red pen, purple pen) without replacement is 10/33.

a) There are 36 sample points that are possible.

b) The probability of obtaining a value of 7 is 1/12.

c) The probability of obtaining a value of 8 or greater is 1/6.

(a) When rolling a pair of dice, each die has six possible outcomes: 1, 2, 3, 4, 5, or 6. The possible outcomes for the pair of dice can be represented by the set of all ordered pairs (a, b), where a and b represent the outcomes of the first and second die, respectively.

Since each die has six possible outcomes, there are a total of 6 x 6 = 36 possible outcomes for rolling a pair of dice.

(b) To obtain a sum of 7, we must have one die showing 1 and the other die showing 6, or one die showing 2 and the other die showing 5, or one die showing 3 and the other die showing 4, for a total of three possible outcomes.

Since each die has six possible outcomes, there are a total of 6 x 6 = 36 possible outcomes. Therefore, the probability of obtaining a sum of 7 is 3/36, or 1/12.

(c) We must have one die showing 2 and the other die showing 6, or one die showing 3 and the other die showing 5, or one die showing 4 and the other die showing 4, or one die showing 4 and the other die showing 5, or one die showing 5 and the other die showing 3, or one die showing 6 and the other die showing 2, for a total of 5 + 1 = 6 possible outcomes.

The length and breadth of the rectangle are 25.33 meters and 12.67 meters,

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

We are given that the breadth of the rectangle is half of its length, so we can write:

B = 0.5L

We are also given that the perimeter of the rectangle is 76m. The perimeter of a rectangle is the sum of the lengths of all four sides, which in this case is:

Perimeter = 2(L + B)

Substituting the value of B from the first equation, we get:

Perimeter = 2(L + 0.5L)

Perimeter = 2(1.5L)

Perimeter = 3L

Now we can solve for L:

3L = 76

L = 25.33

So the length of the rectangle is 25.33 meters.

To find the breadth, we can substitute this value of L back into the first equation:

B = 0.5L

B = 0.5(25.33)

B = 12.67

So the breadth of the rectangle is 12.67 meters.

Therefore, the length and breadth of the rectangle are 25.33 meters and 12.67 meters, respectively.

Let the numerator be x and let the denominator be y.

We are told that the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2,the result is 4. Thus;

4x/(y - 2) = 4

4x = 4y - 8

4x - 4y = -8   -----(1)

The numerator of the fraction is increased by 15 and 2 subtracted from the double of the denominator, the result is 5/4. Thus;

(x + 15)/(2y - 2) = 5/4

4x + 60 = 10y - 10

4x - 10y = - 70   ----(2)

Subtract eq 2 from eq 1 to get;

A statement which best describes the function include the following: A. f(x) is a linear function because x and f(x) are both increasing.

In Mathematics, a linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate. This ultimately implies that, a linear function has the same slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.

Next, we would determine the slope by using the points contained in the table as follows;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (5 - 1)/(0 + 1)

Slope (m) = 4.

Slope (m) = (13 - 5)/(2 - 0)
