The value of arithmetic progression of p = 0 and q = 10
What is arithmetic progression ?When there are identical differences between every two next words, the series is known as an arithmetic progression (AP). There is a chance to find a formula for the nth term of the AP using this kind of development. The series 2, 6, 10, 14, etc., for instance, is an example of an arithmetic progression (AP) because it follows a pattern in which each number is acquired by adding 4 to the preceding word.
Given that : -10,p,q,20 are in A.P
if this -10,p,q,20 are in A.P then it must follow
2b = a+ c
2p = -10 + q ... (i)
2q= p+20 ....(ii)
Solving both equation we get
Multiplying (1) with 2,
4p - 2q = -20
Now adding both the equations
4p - 2q + 2q - p = 0
3p = 0
p = 0
Then, q = 0 + 10 = 10

2 x 10 to the negative 6 power times what number is equal to 6 x 10 to the negative 4 power?
Answers
By using division, 2×[tex]10^{-6}[/tex] times 300 is equal to 6×[tex]10^{-4}[/tex]
Scientific notation is a form of writing a very larger number or very smaller number in a simpler form. The general form of the scientific notation is a number from 1 to 10 is multiplied by a power of 10.
Consider the unknown number as x
The first number = 2×[tex]10^{-6}[/tex]
The result of 2×[tex]10^{-6}[/tex] times x = 6×[tex]10^{-4}[/tex]
So the equation will be
2×[tex]10^{-6}[/tex] × x = 6×[tex]10^{-4}[/tex]
Move 2×[tex]10^{-6}[/tex] to the right hand side of the equation
x = 6×[tex]10^{-4}[/tex] ÷ 2×[tex]10^{-6}[/tex]
Here we have to use the division
x = 300
Hence, by using division, 2×[tex]10^{-6}[/tex] times 300 is equal to 6×[tex]10^{-4}[/tex]

How can linear addition and subtraction be carried out?
In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation. It is one of the fundamental mathematical operations we employ on a daily basis.
An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol, or, denotes subtraction.
Let the initial score of Rapunzel be = x
Given, she first lost nine points thrice and then three points, thus her score is: x - (9*3) - 3 = (x - 30) points.
Thus, the total change to her score is (x-30) points.

Answers
An nth- degree polynomial function with real coefficient for N = 3 ; 3, 2i are zeros ; f(-1) =20 is given by f(x) = (-1)( x³ -3x²+4x -12).
As given in the question,
Number of zeros of the polynomial function N = 3
Real and complex zeros = 3, 2i , -2i
Function value f(-1) = 20

⇒f(x) =k(x-3)(x²+4)
⇒f(-1) = k(-1-3)((-1)² +4)
⇒ 20 =k(-4)(5)
⇒k =-1
Now , f(x) = (-1)((x-3)(x²+4)
= (-1)(x³ -3x²+4x -12)

By applying the distributive property of multiplication, the students that are correct in their approach to solving the problem are: Nico, Raj and Sandra.
How to solve the given equation?In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 5/2 as follows:
2/5(5 + x) = 8
Multiplying both sides by 5/2, we have:
5/2 × 2/5(5 + x) = 8 × 5/2
5 + x = 40/2
5 + x = 20
Subtracting 5 from both sides, we have:
5 + x - 5 = 20 - 5
x = 15
Method 2.In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 1/2 and then 5 as follows:
2/5(5 + x) = 8
Multiplying both sides by 1/2, we have:
1/2 × 2/5(5 + x) = 8 × 1/2
1/5(5 + x) = 4
Multiplying both sides by 5, we have:
5 × 1/5(5 + x) = 4 × 5
5 + x = 20
Subtracting 5 from both sides, we have:
5 + x - 5 = 20 - 5
x = 15
Method 3.In order to open the bracket and isolate the variable x, we would apply the distributive property of multiplication:
2/5(5 + x) = 8
2/5 × 5 + 2/5 × x = 8
2 + 2x/5 = 8
Subtracting 2 from both sides, we have:
2 - 2 + 2x/5 = 8 - 2
2x/5 = 6
Multiplying both sides by 5/2, we have:
5/2 × 2x/5 = 5/2 × 6
x = 30/2
x = 15.

if two distinct numbers are selected at random from the first seven prime numbers, what is the probability that their sum is an even number? express your answer as a common fraction.
Answers
The probability that a sum is an even number will be 5/7.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The probability is typically defined as the proportion of favorable outcomes to all outcomes in the sample space. The probability of an event P(E) = (Number of favorable outcomes) is how it is stated (Sample space).So, the first 7 prime numbers:
2,3,5,7,11,13,17Then,
Even numbers are always produced when two odd numbers are added together.Odd numbers are always created when Even numbers are added to Odd numbers.In the list of 7, there is only one even number. If that is one of the options, then the outcome will only be odd.As the same number cannot be chosen twice, there is a 6/7 chance that it won't be chosen the first time and a 5/6 chance that it won't be chosen the second time.By multiplying these two probabilities, we can determine the likelihood of an even sum.
5/6 × 6/730/425/7Therefore, the probability that a sum is an even number will be 5/7.

Angle 1 = 3x
Angle 2 = x + 30°
Angle 3 = 180° - 120° = 60°
The value of x will be:.

The mean and standard deviation for the number of correct answers for such students is; μ = 6.5 and σ = 1.802776
How to find the mean and standard deviation?Given there is a surprise true/false test with 13 questions.
Thus, the probability of correctly guessing the answer is; p=0.5
Let "X' be the answers correctly guess by a student.
The formula for the binomial probability distribution is;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
A) The mean of the binomial distribution is given by the formula;
μ = np
μ = 13 * 0.5
μ = 6.5
The formula for standard deviation is:
σ = √(np(1 - p))
σ = √(13 * 0.5(1 - 0.5))
σ = 1.802776
B) The probability that the student getting at least 11 correctanswers is given by:
P(X ≥ 11) = P(X = 11) + P(X = 12) + P(X = 13)
