The LCM of A = 3² × 5⁴ × 7 and B = 3⁴ × 5³ × 7 × 11 is 3898125 using Prime factorization.
Given are two numbers which are showed in the prime factorized form.
A = 3² × 5⁴ × 7
B = 3⁴ × 5³ × 7 × 11
Prime factorization is the factorization of a number in terms of prime numbers.
In order to find the LCM of these two numbers, we have to first match the common primes and write down vertically when possible and then bring down the primes in each column.
A = 3² × 5³ × 5 × 7
B = 3² × 3² × 5³ × 7 × 11
Bring down the primes in each column.

List A i.e. |-6(5/7)|, |-6(3/7)|, |5(2/7) shoe the absolute value in order from greatest to the lowest.
What is absolute value?Without taking direction into account, absolute value defines how far away from zero a certain number is on the number line. A number can never have a negative absolute value.
By deducting 1, you may determine the numbers' decreasing order. To write the numbers 10 to 6 in descending order, for instance, we would start with 10, the greatest number in the preceding series, and continue taking away 1 until we reached the lowest number.
There are 4 lists given from which it is obtained only list A is only in which the numbers are in descending order,
|-6(5/7)| = +6.71
|-6(3/4) = +6.42
|-5(2/7)} = +5.28
The numbers are in decreasing order as,
+6.71 > +6.42 > +5.28
Thus, list A i.e. |-6(5/7)|, |-6(3/7)|, |5(2/7) shoe the absolute value in order from greatest to the lowest.

Suppose a researcher wants to use a confidence interval to estimate an unknown population proportion p. Which of the following is not a correct statement?
Answer choices:
A. The endpoints of the interval can vary with each new sample.
B. The probability that p is in the interval is equal to the level of confidence for the interval.
C. Whether the interval captures p is not known with certainty.
D. The population proportion p is fixed, but the sample proportion pˆ can vary from sample to sample.
E. The interval either does or does not capture p.
Using probability the correct option is B)The probability that p is in the interval is equal to the level of confidence for the interval.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject because it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.
The probability that p is in the interval is equal to the level of confidence for the interval.
Reason -
There is a 95% probability that the interval between X [lower bound] and Y [upper bound] contains the true value of the population parameter. The statement above is the most common misconception about confidence interval. After the statistical interval is calculated, the interval can only either contain the population parameter or not.
Hence the correct option is B) The probability that p is in the interval is equal to the level of confidence for the interval.

Two cars leave the same point at the same time traveling in opposite directions. One car travels west at 20 mph and the other travels east at 60 mph. In how many hours will they be 280 miles apart?
-Please provide step by step :)
Answer:
3.5 hours
Step-by-step explanation:
It is given that,
Velocity of first car, v = 20 mph
Velocity of second car, v' = 60 mph
They are moving in opposite direction. Their relative speed is given by :
V = 20 mph + 60 mph = 80 mph
Distance, d = 280 miles
So,
\(t=\dfrac{d}{V}\\\\t=\dfrac{280}{80}\ h\\\\t=3.5\ h\)
Hene, they will be 280 mile apart in 3.5 hours.
induction can be used to prove the following is true for every nonnegitive integer n
Yes ,induction can be used to prove the following is true for every nonnegitive integer n.
If P (n) is true, so is P (n + 1) because this argument holds true for any nonnegative integer n, it establishes the second fact required by the induction proof. As a result of the Induction Principle, the predicate P (m) is true for all nonnegative integers, m.
Mathematical induction is a technique for proving the truth of a statement, theorem, or formula for each and every natural number n. This is generalized as the 'Principle of Mathematical Induction,' which we would use to prove any mathematical statement.
For instance, 13 +23 + 33 +..... +n3 = (n(n+1) / 2)

a) The algebraic fraction \(\frac{{x + 2}}{{(x - 1)^2}}\) is proper. b) The algebraic fraction \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}}\) can be expressed as \(-\frac{{31}}{{x - 4}} - \frac{{25}}{{(x - 4)^2}}\).
Let's solve each part step by step and determine whether the fraction is proper or improper, and then express it accordingly.
a) \(\frac{{x + 2}}{{(x - 1)^2}}\):
Step 1: Determine the degree of the numerator and the denominator:
- Degree of the numerator = 1 (linear term)
- Degree of the denominator = 2 (quadratic term)
Since the degree of the numerator is less than the degree of the denominator, the fraction is proper.
Step 2: Express the proper fraction in partial fractions:
\(\frac{{x + 2}}{{(x - 1)^2}} = \frac{A}{{x - 1}} + \frac{B}{{(x - 1)^2}}\).
Step 3: Find the values of A and B:
Multiply both sides of the equation by \(((x - 1)^2)\) to eliminate the denominators:
(x + 2) = A(x - 1) + B.
Expand the equation and collect like terms:
x + 2 = Ax - A + B.
Equate the coefficients of like terms:
Coefficient of x: 1 = A.
Constant term: 2 = -A + B.
Solve the system of equations to find the values of A and B:
From the coefficient of x, A = 1.
Substituting A = 1 into the constant term equation: 2 = -1 + B, we find B = 3.
Therefore, the partial fraction decomposition is:
\(\frac{{x + 2}}{{(x - 1)^2}} = \frac{1}{{x - 1}} + \frac{3}{{(x - 1)^2}}\).
b) \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}}\):
Step 1: Determine the degree of the numerator and the denominator:
- Degree of the numerator = 2 (quadratic term)
- Degree of the denominator = 2 (quadratic term)
Since the degree of the numerator is equal to the degree of the denominator, the fraction is proper.
Step 2: Express the proper fraction in partial fractions:
\(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}} = \frac{A}{{x - 4}} + \frac{B}{{(x - 4)^2}}\).
Step 3: Find the values of A and B:
Multiply both sides of the equation by \(((x - 4)^2)\) to eliminate the denominators:
(4x^2 - 31x + 59) = A(x - 4) + B.
Expand the equation and collect like terms:
4x^2 - 31x + 59 = Ax - 4A + B.
Equate the coefficients of like terms:
Coefficient of \(x^2\): 4 = 0 (No \(x^2\) term on the right side).
Coefficient of x: -31 = A.
Constant term: 59 = -4A + B.
Solve the system of equations to find the values of A and B:
From the coefficient of x, A = -31.
Substituting A = -31 into the constant term equation: 59 = 4(31) + B, we find B = -25.
Therefore, the partial fraction decomposition is:
\(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}} = -\frac{{31}}{{x - 4}} - \frac{{25}}{{(x - 4)^2}}\).
The above steps provide the solution for each part, including determining if the fraction is proper or improper and expressing it in partial fractions.

We set h equal to 27, because we want the height to be 27 when we solve for t.
That leaves us with:
27 = 7 + 44t - 16t^2
Simplify like terms,
20 = 44t - 16t^2
Move 20 onto the right side, so we can use quadratic equation
