The division yields 1/14 for the complex fraction.
What is division?Division is one of the four basic operations of arithmetic, along with addition, subtraction, and multiplication. It is an inverse operation to multiplication, meaning that dividing by a number is the same as multiplying by its reciprocal. Division can be thought of as the process of finding how many times a number (the divisor) can fit into another number (the dividend). The result of the division is called the quotient. In some cases, the division may result in a fractional number, representing a partial division. In this case, the result is a rational number, which is a type of real number. Division can also be represented using long division, a method used to divide large numbers or polynomials. It involves dividing the dividend by the divisor one digit at a time, until the division is complete.
Here,
=22/44/7
=22/44*1/7
=1/14
The answer for the complex fraction is 1/14 by the division.

a person bets you that in 100 tosses of a fair coin the number of heads will differ from 50 by 4 or more. what is the probability that you will win this bet?
Answer:
The probability of winning the bet is approximately 0.4238, or about 42.38%.
Step-by-step explanation:
We can solve this problem using the normal approximation to the binomial distribution. Let X be the number of heads in 100 tosses of a fair coin. Then X follows a binomial distribution with n = 100 and p = 0.5. The mean of X is µ = np = 100 × 0.5 = 50, and the standard deviation of X is σ = sqrt(np(1-p)) = sqrt(100 × 0.5 × 0.5) = 5.
Now, we want to calculate the probability that |X - 50| ≥ 4. This is equivalent to calculating the probability that |(X - 50)/5| ≥ 4/5, which is the probability that a standard normal variable Z = (X - 50)/5 is less than -4/5 or greater than 4/5. Using a standard normal distribution table or a calculator, we can find:
P(Z ≤ -4/5) ≈ 0.2119
P(Z ≥ 4/5) ≈ 0.2119
Therefore, the probability of winning the bet is:
P(|X - 50| ≥ 4) = P(|(X - 50)/5| ≥ 4/5)
≈ P(Z ≤ -4/5 or Z ≥ 4/5)
≈ P(Z ≤ -4/5) + P(Z ≥ 4/5)
≈ 0.2119 + 0.2119
≈ 0.4238
So the probability of winning the bet is approximately 0.4238, or about 42.38%.

How do you use the distributive property to write the expression without parentheses: 6(a-2)?
Answer:
\(6(a - 2) = 6a - 12\)
Find the product of (3 x 107)and (2 x 107). Write the final answer in scientific notation. !!!!!!!!!!!!!!!!!!!
The product of (3 x 107) and (2 x 107) is 6.8694 x 10^4
To find the product of (3 x 107)and (2 x 107), we can use the distributive property of multiplication which states that the product of a number and a sum is equal to the sum of the products of the number and each term in the sum. In this case, we can multiply the numbers outside the parentheses first, and then multiply the result by the common factor of 107 to simplify the expression:
(3 x 107) x (2 x 107) = 6 x (107 x 107)
Next, we can calculate the product of 107 and 107, which is 11,449:
6 x 11,449 = 68,694
In scientific notation, this can be written as:
= 6.8694 x 10^4

What is the equation of the line that passes through the point (2-,5) and a slope of -6???
Answer:
y = -6x - 7
Step-by-step explanation:
We already know the slope so all we need to do is find th y-intercept. We can do this by using slope-intercept form and substituting the values we are given.
y = mx + b
5 = -6(-2) + b
5 = 12 + b
-7 = b
Put everything we know back into the formula.
y = -6x - 7

The measure of angle ∠RST in degree is 156°
What is measure of an angle?The measure of angle is the amount of rotation performed by initial side to get the terminal side. A complete angle is divided by 360 equal parts we get 360 number of small angles. Each of these small angle has measure 1 degree.
Given that, ∠RSU=78° , ∠UST=(3x - 11)° and ∠RST=(6x + 12)°
Now, ∠RSU+UST=∠RST
Putting the values of ∠RST and ∠UST we get,
78 + (3x - 12) = 6x + 12
78 + 3x - 12 - 6x - 12 = 0
54 - 3x = 0
3x = 54
So, x = 54/3=18
Therefore, (6x + 12)°=(6×18 + 12)°
=(144 + 12)°
=156°

B. 2(x+3)2 +4=1
C. (x - 1)² + 4 = 8
The equation that has no real solutions is 2(x+3)² + 4 = 1. The correct answer is option B.
As we know that the quadratic equation is defined as a function containing the highest power of a variable is two.
As per the question,
A. 2(x-3)² = 0
Here, it has one real solution x = 3.
B. 2(x+3)² +4=1
Here, it can be simplified to 2(x+3)² = -3 which has no real solutions.
C. (x - 1)² + 4 = 8
Here, it can be simplified to (x - 1)² = 4 which has two real solutions x = 3 and x = -1.

Find the Taylor series for f(x) centered at the given value of a. [Assume that f has a power series expansion. Do not show that Rn(x) → 0. ] f(x) = ln x, a = 4 Find the associated radius of convergence R.
The associated radius of convergence R is 0.
Answer: \(ln(4) + (1/4)(x-4) - (1/32)(x-4)^2 + (1/64)(x-4)^3 - (3/256)(x-4)^4 and R = 0.\)
We need to find the Taylor series for f(x) centered at the given value of a.
To find the Taylor series for ln(x) function we use the formula of the Taylor series which is:
\(f(x) = f(a) + f'(a)(x-a)/1! + f''(a)(x-a)^2/2! + ....+ f^n(a)(x-a)^n/n!......eqn.1\)
Differentiating the given function ln(x), we get;
\(f'(x) = 1/x ......eqn.2\\f''(x) = -1/x^2 .......eqn.3\\f'''(x) = 2!/x^3 .....eqn.4\\f^4(x) = -3! /x^4 ....eqn.5\)
Therefore, substituting the values of a, f(a), f'(a), f''(a), f'''(a) and f^4(a) in eqn.1, we get;
\(ln(x) = ln(4) + (1/4)(x-4) - (1/32)(x-4)^2 + (1/64)(x-4)^3 - (3/256)(x-4)^4 ......eqn.6\)
The associated radius of convergence R is given by the formula;
\(R = lim |a_n / a_n+1 |\)
where a_n is the nth term of the series.
In this case, the nth term is (x-4)^n/n!
Therefore, \(a_n+1 = (x-4)^(n+1) / (n+1)! and a_n = (x-4)^n/n!.\)
Substituting these values in the formula, we get;
\(R = lim|(x-4)^n/n! x (n+1)!/(x-4)^(n+1) |\)
on simplifying, we get;
\(R = lim |(x-4)/(n+1)|\)
as n approaches, infinity, the denominator in the above equation becomes very large, and thus R approaches 0.
Hence the associated radius of convergence R is 0. Answer: \(ln(4) + (1/4)(x-4) - (1/32)(x-4)^2 + (1/64)(x-4)^3 - (3/256)(x-4)^4\) and R = 0.

the probability that the diameter of a elected bearing is greater than 85 millimeter P(diameter > 85) = P(z > (85-81)/4) = P(z > 1) = 0.1587
The diameter of ball bearings is normally distributed, with a mean of 81 millimeters and a variance of 16.
To calculate the probability that a selected bearing has a diameter greater than 85 millimeters, we first calculate the z-score for 85 millimeters.
We subtract 81 from 85 to get 4, and divide by 4 to get 1 for the z-score.
We the look up the probability for a value of 1 in the z-table, which is 0.1587.
This is the probability that a selected bearing has a diameter greater than 85 millimeters, rounded to four decimal places.

The given equation is not instandard form. First standard form is neccesary.
Add 108 to both sides.Subtract 12y to both sidesThe result is 3x + 108 = 12y which is equal to 12y = 3x + 108
