For a real number a, a + 0 = a is that true?
For a real number a, a + 0 = a: TRUE
What are real numbers?In mathematics, a real number is a quantity that can be expressed as an infinite decimal expansion. In contrast to the natural numbers 1, 2, 3,..., which are derived from counting, real numbers are used in measurements of continuously varying quantities such as size and time.For a real number a, a + 0 = a:
This is due to the identity property for addition, which states that zero added to any number equals the number itself. So, in this case, the number is, and it is true that: a + 0 = aTherefore, the statement "for a real number a, a + 0 = a" is TRUE.

Let us suppose Christmas lights have a total of 120 bulbs in a set, each with a 99.9% reliability rating. What is the probability that a set all works?
The probability that a set of all bulbs work is 0.88.
What is called as the total probability?The total probability rule (also known as the Law of Total Probability) divides probability calculations into discrete steps.
It's used to calculate the probability of an event, A, once you don't know enough about A's probabilities to do so directly. Instead, you use a related event, B, to calculate the probability of A.Two events are considered independent if a occurrence of one does not affect the likelihood of occurrence of the other.Now, as per the question;
The total number of bulbs be 120 and each bulb is working as independent event.
The reliability of each bulb is 99.9% = 0.999
Let 'p' the probability the bulb will work.
The probability that all will work = p¹²⁰
The probability that all will work = (0.999)¹²⁰ = 0.886
Thus, the probability that all bulb will work is 88.6%.

What is the relationship between the numerator and the denominator in a fraction?
Answer: GoodMorning: )✨Ok so We should Know that The top number in a fraction is always considered a numerator, and that It shows the number of parts we have. The bottom number in a fraction is considered a denominator. It shows the total number of parts into which anything is divided. For example, in the fraction 8/7, 8 is the numerator and 7 is the denominator.
Step-by-step explanation: Like In this fraction 7/3, 7 is the numerator and 3 is the denominator. In the fraction 9/7, 9 is the numerator and 7 is the denominator.The value placed above the horizontal line in a fraction is called a numerator. It signifies the number of parts taken out of the whole. The numeric value below the vinculum of a fraction is called the denominator. It represents the total number of equal parts as a whole. Hope this helps: )

Katy invests a total of $10,500 in two accounts paying 11% and 5% simple interest, respectively. How much was invested in each account if, after one year, the total interest was $945.00.
A) Enter an equation that uses the information as it is given that can be used to solve this problem. Use x as your variable to represent the amount of money invested in the account paying 11% simple interest.
Equation:___________
B) The answers are:
$____ was invested at 11% and
$____was invested at 5%
Answer:
Equation: 0.11x + 0.05(10500 - x) = 945
$7000 was invested at 11% and
$3,500 was invested at 5%
Step-by-step explanation:
There are two equations needed
Let x = amount of money invested at 11%
11% = 11/100 = 0.11 in decimal
Interest at 11% for 1 year = 0.11x
Amount of money invested at 5% interest. 5% = 0.05
= 10500 - amount invested at 11%= 10500 - x
Interest from this amount after 1 year = 0.05(10500 - x)
Total of these two = 945
So 0.11x + 0.05(10500 - x) = 945
The equation based on the information as it is given:
0.11x + 0.05(10500 - x) = 945
We know the total interest obtained was $945 so we have the equation
0.11x + 0.05(10500- 5x) = 945
Simplify
0.11x + (525 - 0.05x) = 945
==>0.11x + 525 - 0.05x = 945
==> 0.06x = 945 - 525
==> 0.06x = 420
==> x = 420/0/06 = $7000
Amount invested at 11% interest is $7,000
Amount invested at 5% interest = 10,500 - 7,000 = $3,500

What is number system?A system of writing numbers is known as a number system. It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set. It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.Now,
Natural numbers are positive integers with a range of 1 to infinity; nevertheless, they do not include zero. -25 wouldn't be a natural number because it is a negative number.A group of numbers known as a whole number consists of all positive integers and 0. This wouldn't be a whole number because -25 isn't a positive number.Any real number that cannot be represented as the quotient of two integers is said to be irrational. Square roots of irrational numbers are also frequently seen. -25, however, is not a square root.Any number that can be expressed as a ratio, or a fraction, of two integers, is referred to be a rational number. Fractions, decimals, negative decimals, and other rational numbers are very prevalent. Since -25 can be represented as a ratio of two numbers. it is a rational number.A whole number that can be either positive, negative, or zero is known as an integer. As -25 is negative and a whole number( when positive), it is an integer.Hence, -25 is an integer and a rational number.

How to graph linear equations?
Here we want to graph the line:
y = 3x - 2 (I think this is the line, the image is really blurry).
To graph this line (or any line, actually) what you need to do is find two points on the line.
To do so, you need to evaluate the function.
If we use x = 0, then:
y = 3*0 - 2 = -2
So we have the point (0, -2)
If we use x = 1, then:
y = 3*1 - 2 = 1
So we have the point (1, 1)
Now just graph these two points, and then draw a line that passes through both of them, you should get something like the image below.

Use vectors to decide whether the triangle with vertices p(1,-3,-2), q(2,0,-4), and r(6,-2,-5) is right-angled.
The given vertices make a right angled triangle as seen below, with the help of vectors.
What are vectors?Vectors refer to the quantities that have both magnitude and direction but not position.
Now,
Given: Three vertices of a triangle: P(1,-3,-2),Q(2,0,-4), and R(6,-2,-5).
To find: whether they make a right angled triangle.
Finding:
Now,
Any two of the triangle's vectors must have a dot product of zero in order to demonstrate that the triangle is a right triangle. This is because the vectors (which represent the sides) are perpendicular or orthogonal if the dot product is 0, which indicates that the angle they make is right (90°).The triangle's three sides can be represented by the following three directional vectors:
Vector (PQ) = <2, 0, -4> - < 1, -3, -2>
=> Vector (PQ) = < 1, 3, -2>
Vector (QR) = < 6, -2, -5> - < 2, 0, -4>
=> Vector (QR) = < 4, -2, -1>
Vector (PR) = < 6, -2, -5> - <1, -3, -2>
=> Vector (PR) = < 5, 1, -3>
Now, finding a pair of vectors whose dot product = 0:
Vector(PQ) . Vector(PR) = < 1, 3, -2> . < 5, 1, -3> = 5 + 3 + 6 = 14 ≠ 0Vector (QR) . Vector (PR) = < 4, -2, -1> . < 5, 1, -3> = 20 + (-2) + 3 = 21 ≠ 0Vector (PQ) . Vector (QR) = < 1, 3, -2> . < 4, -2, -1> = 4 + (-6) + 2 = 0Hence, the sides PQ and QR must be perpendicular so that the given vertices make a right-angled triangle.

If participant A's batting common is .312 and he had 596 at-bats , what number of hits did he get?
The number of hits A got is 186 hits.
A player's batting average is calculated by dividing the number of hits by the number of at-bats.
Player A batting average = 0.312
Number of at-bats A did = 596
We have to find the number of hits A got.
0.312 = Number of hits / 596
Number of hits = 0.312 x 596
