Addition, subtraction, multiplication, and division are the four fundamental arithmetic operations that represent algebraic operations on complex numbers.

Using letters or alphabets to represent numbers without giving their exact quantities is the idea behind algebraic expressions. The principles of algebra taught us how to express an unknown value using letters like x, y, and z. These letters are referred to here as variables. Constants and variables can both be used in an algebraic expression.

Any amount that is added before a variable and then multiplied by it is referred to as a coefficient.

4x + 3y - 8 , x - 4, and so forth.

These expressions are represented by variables, constants, and coefficients that are unknown. The combination of these three words is referred to as an expression. It should be noted that, in contrast to an algebraic equation, an algebraic expression lacks sides and the equal sign.

In mathematics, addition, subtraction, multiplication, and division are the four fundamental arithmetic operations that represent algebraic operations on complex numbers.

The area of the shaded sector is 9π unts²

The term "turn" also refers to a 360° rotation. Angles between 0° and 360° are calculated. We require a circle's circumference, which is equal to 2 r r, where r is the circle's radius.

In any circle of radius r, the ratio of the arc length ℓ to the circumference equals the ratio of the angle θ subtended by the arc at the center and the angle in one revolution. Thus, measuring the angles in radians, ℓ2πr=θ2π⟹ ℓ=rθ.

Find the diagram attached

Given the following

Radius = 6

Theta = pi/2 = 90°

Area of the sector = theta/360×πr²

So, for this equation we get:

The required probability that 2 or fewer students are left-handed in a random sample of 65 students from the school is 0.0360.

Let X be a random variable which denotes the number of students who are left handed out of a sample of 65 students.

Here we have 65 students, therefore the number of trials would be 65. It would be reasonable to assume that the probability of one student being left handed is independent of any other student.

Therefore, the trials are independent.

There are only two possible outcomes for each trial i.e, either success or failure. The probability of success for each trial is 0.1

Hence we can say that X follows a binomial distribution with n = 65 and p = 0.1

X ~ Bin(65,0.1)

We need the probability that 2 or fewer students are left handed. This is given as :

P(X≤2)

we shall use the BINOM.DIST() function to find this

The syntax is given as:

= BINOM.DIST(number_s,trials,probability_s,cumulative)

Here,

number_s denotes the number of success required (2 in this case)

trials is the number of trials(65 in this case)

Probability_s is the probability of success in each trial (0.1 in this case)

cumulative, if true indicates the CDF or false if the PDF of X(TRUE in this case)

Hence the function which we use is

= BINOM.DIST(2,64,0.1,TRUE)

on running this code in any cell of excel, we get the probability as 0.035973

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Yolanda is charged $21.95 for her monthly fee and 4 movie rentals.

And, Jeffrey is charged $30.92 for the same monthly fee and 7 movie rentals.

Now,

Let the price for the monthly fee = x

And, The price for the movie rental = y

Hence, We can formulate the expression for Yolanda;

⇒ x + 4y = $21.95

And,  We can formulate the expression for Jeffrey;

⇒ x + 7y = $30.92

Subtract equation (ii) from (i), we get;

⇒ 7y - 4y = $30.92 - $21.95

⇒ 3y = $8.97

⇒ y = $2.99

And, x + 4y = $21.95

x + 4 × 2.99 = 21.95

x + $11.96 = $21.95

x = $21.95 - $11.96

x = $9.99

Assuming that Nathalie's weight is still measured in pounds and ounces and that she has not lost or gained any weight since her birth, we can calculate her current weight as follows:

A) Nathalie weighs 7 pounds and 9 ounces at birth, which is equal to 7.5625 pounds. If she now weighs 12 times as much, she weighs 7.5625 * 12 = 90.75 pounds. In ounces, this is equal to 90.75 * 16 = 1452 ounces.

B) To calculate the percentage increase in Nathalie's weight, we need to first calculate the increase in her weight, which is equal to 90.75 - 7.5625 = 83.1875 pounds. We can then divide this increase by her original weight of 7.5625 pounds and multiply by 100% to express the result as a percentage: (83.1875 / 7.5625) * 100% = 1103.9%. This means that Nathalie's weight has increased by more than 1100% since she was born.

The amount of money invested at the rate [tex]2\frac{1}{4}[/tex]% is $8500 and the amount of money invested at the rate 2% is $3000.

Given that, Phyllis invested $11,500, a portion earning a simple interest rate of [tex]2\frac{1}{4}[/tex] % per year and the rest earning a rate of 2% per year.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest is calculated with the following formula: S.I. = (P × R × T)/100, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.

Let x be the amount invested at [tex]2\frac{1}{4}[/tex] =2.25% per year

Now, S.I= (x×2.25×1)/100

= 0.0225x

Then, (11,500-x) be the amount invested at 2% per year

S.I =((11,500-x)×2×1)/100

=(11,500-x)×0.02

= 230-0.02x

After one year the total interest earned on these investments was $251.25.

Now, 0.0225x+230-0.02x=251.25

⇒ 0.0025x+230=251.25

⇒ 0.0025x=21.25

⇒ x=21.25/0.0025

⇒ x=$8500

So, 11,500-x=$3000

To find the values of the trigonometric functions, we need to know the angle whose cosine, sine, etc. we are trying to find. In this case, we are given that the cosine of the angle is 3/5, but we are not told the measure of the angle itself. We can find the values of the other trigonometric functions using the given value of the cosine, but we must first express the value in radians.

Since the cosine of an angle is equal to the x-coordinate of the point on the unit circle that is located on the terminal side of the angle, we can find the value of the angle in radians by finding the inverse cosine (cos^-1) of 3/5. In other words, we want to find the angle such that the cosine of the angle is 3/5.

The inverse cosine function is denoted by cos^-1, so we can write:

$\cos^{-1}(3/5) = \theta$

where $\theta$ is the measure of the angle in radians.

To find the value of the other trigonometric functions, we can use the following relationships:

$\cos^2\theta = 1 - \sin^2\theta$

$\tan^2\theta = \frac{\sin^2\theta}{\cos^2\theta} = \frac{1 - \cos^2\theta}{\cos^2\theta}$

$\csc^2\theta = \frac{1}{\sin^2\theta}$

$\sec^2\theta = \frac{1}{\cos^2\theta}$

$\cot^2\theta = \frac{\cos^2\theta}{\sin^2\theta} = \frac{\cos^2\theta}{1 - \cos^2\theta}$

We can now plug in the value of $\theta$ that we found earlier and use these relationships to find the values of the other trigonometric functions:

a. $\cos\theta = \cos(\cos^{-1}(3/5)) = \frac{3}{5}$

b. $\sin^2\theta = 1 - \cos^2\theta = 1 - (\frac{3}{5})^2 = \frac{4}{25}$

c. $\cos^2\theta = (\frac{3}{5})^2 = \frac{9}{25}$

d. $\tan^2\theta = \frac{\sin^2\theta}{\cos^2\theta} = \frac{\frac{4}{25}}{\frac{9}{25}} = \frac{4}{9}$

e. $\csc^2\theta = \frac{1}{\sin^2\theta} = \frac{1}{\frac{4}{25}} = \frac{25}{4}$

f. $\sec^2\theta = \frac{1}{\cos^2\theta} = \frac{1}{\frac{9}{25}} = \frac{25}{9}$

g. $\cot^2\theta = \frac{\cos^2\theta}{\sin^2\theta} = \frac{\frac{9}{25}}{\frac

Using the slope formula, we know that the relationship between AB and CD is that they are (C) parallel.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

A line's steepness can be determined by looking at its slope.

The slope is calculated mathematically as "rise over run" (change in y divided by change in x).

So, formula: m = y2 - y1/x2 - x2

For AB:

m = y2 - y1/x2 - x2

m = -5+2/3-1

m = -3/2

For CD:

m = y2 - y1/x2 - x2

m = 5-2/5-7

m = -3/2
