Power RulesThere are different power rules, see some them:
1. Multiplication with the same base: you should repeat the base and add the exponents.
2. Division with the same base: you should repeat the base and subctract the exponents.
3.Power. For this rule, you should repeat the base and multiply the exponents.
4. Zero Exponent. When you have an exponent equals to zero, the result must be 1.
First, you apply the Power Rules - Power for \((\frac{2^2x^2y}{xy^3} )^2}\). For this rule, you should repeat the base and multiply the exponents. Thus, the result will be:\(\frac{16x^4y^2}{x^2y^6}\).
After that, you should apply the Power Rules - Division . For this rule, you should repeat the base and subctract the exponents. Thus, the result will be:\(\frac{16x^2}{y^4}\).
Now, you should replace the variable x by 4 and the variable y by 2. Thus, the result will be:\(\frac{16*4^2}{2^4}=\frac{16*16}{16} =16*1=16\)

You have received an order of 100 robotic resistance spot welders which contains 5 defective welders. You randomly select 15 welders from the order without replacement to inspect to check whether they are defective.
(a) Determine the PMF of the number of defective welders in your sample? Remember to list all possible values of the random variable.
(b) Determine the probability that there are at least 4 defective welders in the sample? Hint: No need to calculate the final numerical results. Appropriately plugging in numbers in the mathematical expression is sufficient
Answers
Answer:
a)
\(P(X = 0) = h(0,100,15,5) = \frac{C_{5,0}*C_{95,15}}{C_{100,15}} = 0.4357\)
\(P(X = 1) = h(1,100,15,5) = \frac{C_{5,1}*C_{95,14}}{C_{100,15}} = 0.4034\)
\(P(X = 2) = h(2,100,15,5) = \frac{C_{5,2}*C_{95,13}}{C_{100,15}} = 0.1377\)
\(P(X = 3) = h(3,100,15,5) = \frac{C_{5,3}*C_{95,12}}{C_{100,15}} = 0.0216\)
\(P(X = 4) = h(4,100,15,5) = \frac{C_{5,4}*C_{95,11}}{C_{100,15}} = 0.0015\)
\(P(X = 5) = h(5,100,15,5) = \frac{C_{5,5}*C_{95,10}}{C_{100,15}} = 0.00004\)
b) 0.154% probability that there are at least 4 defective welders in the sample
Step-by-step explanation:
The welders are chosen without replacement, so the hypergeometric distribution is used.
The probability of x sucesses is given by the following formula:
\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}\)
In which
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
In this question:
100 welders, so \(N = 100\)
Sample of 15, so \(n = 15\)
In total, 5 defective, so \(k = 5\)
(a) Determine the PMF of the number of defective welders in your sample?
There are 5 defective, so this is P(X = 0) to P(X = 5). Then
\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}\)
\(P(X = 0) = h(0,100,15,5) = \frac{C_{5,0}*C_{95,15}}{C_{100,15}} = 0.4357\)
\(P(X = 1) = h(1,100,15,5) = \frac{C_{5,1}*C_{95,14}}{C_{100,15}} = 0.4034\)
\(P(X = 2) = h(2,100,15,5) = \frac{C_{5,2}*C_{95,13}}{C_{100,15}} = 0.1377\)
\(P(X = 3) = h(3,100,15,5) = \frac{C_{5,3}*C_{95,12}}{C_{100,15}} = 0.0216\)
\(P(X = 4) = h(4,100,15,5) = \frac{C_{5,4}*C_{95,11}}{C_{100,15}} = 0.0015\)
\(P(X = 5) = h(5,100,15,5) = \frac{C_{5,5}*C_{95,10}}{C_{100,15}} = 0.00004\)
(b) Determine the probability that there are at least 4 defective welders in the sample?
\(P(X \geq 4) = P(X = 4) + P(X = 5) = 0.0015 + 0.00004 = 0.00154\)
0.154% probability that there are at least 4 defective welders in the sample

Given,
The box and whisker plot below shows the starting salaries
The number of graduates in a small college = 120
We have to find the range of the starting salaries;
Range of a data;
The difference between the highest and lowest values for a given data collection is the range in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range may alternatively be thought of as the distance between the highest and lowest observation.

If XZ ⊥ WY, XE = 4, and WY = 7, what is the perimeter of WXYZ, rounded to the nearest tenth?
Answers
The perimeter of the rhombus is approximately 7.6 units.
XZ is perpendicular to WY and XE is 4,
Since WXYZ is a rhombus because only the diagonal of the rhombus and square bisect each other at 90°
By the Pythagorean theorem, we have:
XE² = XY² + EY²
4² = XY² + (7/2)²
XY = 1.9
So the perimeter of WXYZ is 4(XY), rounded to the nearest tenth:
4(1.9) ≈ 7.6 units.

How would you graph the solutions to the inequality on a number line? k > 5
Answers
To graph the inequality k > 5 on a number line, mark an open circle at 5 and shade the region to the right.
To graph the solutions to the inequality k > 5 on a number line, follow these steps:
Draw a horizontal line and mark a point for the number 5 on the line.
-------------------|---|---|---|---|---|---|---|---|---|---|
0 1 2 3 4 5 6 7 8 9 10
Since the inequality is k > 5, the solution includes all values greater than 5. Therefore, draw an open circle (○) at the number 5 to represent that 5 itself is not included in the solution.
-------------------|---|---|---|---○---|---|---|---|---|---|
0 1 2 3 4 5 6 7 8 9 10
Shade the region to the right of the open circle. This shading represents all values that are greater than 5 and satisfy the inequality k > 5.

How many roots do the functions have in common f(x)=x^2+x-6
Answers
To find the common roots between two functions, we need to find the roots (or solutions) of each function individually and then identify the shared solutions.
For the function f(x) = x^2 + x - 6, we can find the roots by setting the function equal to zero and solving for x:
x^2 + x - 6 = 0
To factorize this quadratic equation, we need to find two numbers that multiply to -6 and add up to 1 (the coefficient of x). The numbers that satisfy these conditions are 3 and -2:
(x + 3)(x - 2) = 0
Setting each factor equal to zero:
x + 3 = 0 or x - 2 = 0
Solving for x in each equation:
x = -3 or x = 2
Therefore, the function f(x) = x^2 + x - 6 has two roots: x = -3 and x = 2.
To find the common roots between this function and another function, we would need to know the second function. If you provide the second function, I can help determine if there are any shared roots.

Find the missing coordinate to complete the ordered pair for the equation 3x- 4y = 12: When the following are given (0, ?) and (?, 3)
Answers
The missing coordinates on the ordered pairs of the linear equation are:
(0, -4) and (8, 3)
How to find the missing coordinates?Here we have the linear equation:
3x - 4y = 12
And we want to find the missing coordinates for the given points (0, ?) and (?, 3) where these points belong to the line.
The first point is (0, ?), this means that the value of x is zero, then we can evaluate the equation in x = 0 then we will get:
3*0 - 4y = 12
-4y = 12
y = 12/-3 = -4
So the point is (0, -4)
For the other point (?, 3) we need to evaluate in y = 3.
3*x - 4*3 12
3x - 12 = 12
3x = 12 + 12
3x = 24
x = 24/3 = 8
So we have the point (8, 3)
These are the missing coordinates.

The points that must lie on the same graph of the quadratic function is given as follows:
(1,6).
How to obtain the coordinates of the point?The quadratic function in the context of this problem is defined as follows:
y = (x - 3)² + k.
When x = 5, y = 6, hence the value of the constant k is obtained as follows:
6 = (5 - 3)² + k
6 = 4 + k
k = 2.
Hence the equation is:
y = (x - 3)² + 2.
The other point also has a numeric value of y = 6, hence:
(x - 3)² + 2 = 6
(x - 3)² = 4.
Hence the two options are:
x - 3 = -2 -> x = 1.x - 3 = 2 -> x = 5.Hence the point is (1,6).

What is the equivalent to the product below when x>_0?
√5x² •√15x²
Answers
√(5x²) • √(15x²) = √(5x² * 15x²)
Using the property of square roots that √(a * b) = √a * √b, we can simplify further:
√(5x² * 15x²) = √(5 * 15 * x² * x²)
Next, we simplify the numerical part:
√(5 * 15 * x² * x²) = √(75 * x² * x²)
Since x ≥ 0, x² is always non-negative, so we can remove the square root:
√(75 * x² * x²) = x * x * √75
Finally, we simplify the square root of 75:
x * x * √75 = x² * √75
Therefore, the equivalent expression is x² * √75 when x ≥ 0.

What is the equation of a circle?In Mathematics and Geometry, the standard form of the equation of a circle is represented by the following mathematical equation;
(x - h)² + (y - k)² = r²
Where:
h and k represents the coordinates at the center of a circle.r represents the radius of a circle.Note: A center that lies on the y-axis simply means the value of h on the x-axis is equal to 0.
Based on the information provided above, we have the following parameters:
Radius, r = diameter/2 = 12/2 = 6 units.
Center, (h, k) = (0, 3).
By substituting the given parameters into the equation of a circle formula, we have the following;
(x - h)² + (y - k)² = r²
(x - 0)² + (y - 3)² = 6²
x² + (y - 3)² = 36.
