Explanation
The pattern appears to be that the number on the right side of the equation is the last digit of the number on the left side . The last digit of 57 is 7 .

Explanation
Step 1: Calculate the expression -3 + 12 = 9 Step 2: Compare the result to the options Since √81 = 9 (because 9² = 81), the correct answer is √81 .

Explanation
2a³ - a³ = (2-1)a³ = 1a³ = a³ This is because when you subtract a³ from 2a³ , you are essentially subtracting 1a³ from 2a³ , leaving you with 1a³ , which simplifies to a³ .

Explanation
Step 1: Calculate the division 0.3/0.1 = 3 Step 2: Multiply the result by 0.3 3 × 0.3 = 0.9

Explanation
The secant of an angle θ is defined as 1/cos(θ). For θ = 0, cos(0) = 1 . sec(0) = 1/cos(0) = 1/1 = 1 .

Explanation
The cosine of π radians (or 180 degrees) is -1 .

Explanation
The cosine of 0 degrees is 1 .

Explanation
π (pi) is approximately 3.14159 . The value of Pi (π) is the ratio of the circumference of a circle to its diameter.

Explanation
Step 1: Recall the definition of set difference The set difference A - B is the set of elements that are in A but not in B. Step 2: Calculate A - A A = {1,2,3,4} A - A = {} (since every element in A is also in A, the difference is the empty set )

Explanation
The distributive law for sets states that A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C).

Explanation
Scholastic Assessment/Aptitude Test is a standardized test widely used for college admissions in the United States.

Explanation
The SAT originally stood for  "Scholastic Aptitude Test,"  but over time, it became simply known  as the "Scholastic Assessment Test." It is a standardized test widely used for  college admissions in the United States.

Explanation
The arithmetic mean is calculated by adding all the observations and dividing by the number of observations. Given observations: 5, 5, and 5. text{Mean} = frac{5 + 5 + 5}{3} = frac{15}{3} = 5 Mean = 5 + 5 + 5 ​/3 = 15/3 ​ = 5

Explanation
The range of a data set is calculated as the difference between the maximum value and the minimum value: Range = Maximum value − Minimum value Given: Minimum value = 5 Range = 50 Substitute these values into the formula: 50 = text{Maximum value} - 5 50 = Maximum value − 5 Solving for the maximum value: Maximum value = 50 + 5 = 55

Explanation
The mean is a measure of location or measure of central tendency of the distribution on its scale.

Explanation
Personality plays a major role in how an individual reacts to stress. Different personality traits, such as resilience, optimism, or neuroticism, can significantly influence how a person perceives and copes with stressful situations. 

Explanation
