How does Gauss-Jordan Elimination work?
Gauss-Jordan elimination is a method used to solve a system of linear equations by reducing the augmented matrix of the system to a reduced row-echelon form through a series of elementary row operations.
The process involves manipulating the rows of the augmented matrix to obtain a triangular matrix, where all entries below the diagonal are zero. This is achieved by applying elementary row operations such as adding a multiple of one row to another row or multiplying a row by a scalar.
Once the augmented matrix is in triangular form, further elementary row operations are used to eliminate the nonzero entries above the diagonal. This results in the augmented matrix being in reduced row-echelon form, where the pivot elements are all equal to 1 and the columns corresponding to the pivot elements are linearly independent.

The temperature separating the bottom 91% from the top 9% is given as follows:
P91 = -1.34ºC.
How to obtain the measure using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for this problem are given as follows:

An exterminator charges a base fee of $130 plus $75 for each hour of service. Write the equation to model the total charge,y, for a service call that lasts x hours.
Answer:
y = 130 + 75x
My answer is based on the understanding that y is the charge for the service call, x is the number of hours spent on the service call and 130 is the base charge for the service.
Therefore, the 130 dollars is the baseline cost, as it is the charge even if 0 hours are spent. The extra 75 dollars per hour is the additional charge that has to be paid for every each hour that is spent on the job.
Therefore, the equation should be y = 130 + 75x.

What is a ratio?A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.
If the ratio is Jake: Kim: Lee, and the amounts are 1: 3: 6, we can use this ratio to solve for the amount of money Lee will get if Kim gets $9 more than Jake:
5: 15: 30How did we get this ratio?Well, in order to get this ratio, we need to multiply each number in the original ratio by 5.
1 × 5 = 53 × 5 = 156 × 5 = 30Therefore, Kim will get $15, which is $9 more than Jake's amount, which is $5. Lee has $30.
Find the lengths of g, h, and j. Round answers to the nearest tenth.
The sides of the given right triangle are:
g = 33.80
h = 31.20
j = 13
What is a triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total. Any three points in Euclidean geometry, when they are not collinear, produce a distinct triangle. A right triangle is a triangle with two perpendicular sides and one angle that is a right angle.
The given figure has a large right triangle with sides g,h and j and a small right triangle with sides 12, j and 5.
Using the small triangle, we can find the value of j.
By Pythagoras theorem,
j² = 12² + 5² = 144 + 25 = 169
j = 13
Now using trigonometric relation we can find the angle ∅ between j and 5.
sin ∅ = 12/13 = 0.923
∅ = sin ⁻¹ (0.923) = 67.37°
This angle is common for both triangles.
So for large triangle,
tan 67.37 = h/j = h/13
2.4 = h/13
h = 31.2
By Pythagoras theorem,
g² = h² + j² = 31.2² + 13² = 1142.44
g = 33.8
Therefore the sides of the given right triangle are:
g = 33.80
h = 31.20
j = 13.

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options.
y(y + 5) = 750
y2 – 5y = 750
750 – y(y – 5) = 0
y(y – 5) + 750 = 0
(y + 25)(y – 30) = 0
Answer:
y^2 - 5y = 750
Step-by-step explanation:
If length = y
then width = y - 5
Area = length x width
= y(y-5) = 750
Or, y^2 - 5y = 750
This equation can be further solved as follows:
y^2 - 5y - 750 = 0
Or, y^2 - 30y + 25y - 750 = 0
Or, y(y - 30) + 25(y - 30) = 0
Or, (y + 25)(y-30) = 0
So, there are two possibilities:
If (y + 25) = 0
then y = -25
but value of length cannot be negative,
Let us look at second possibility
If (y - 30) = 0
then y = 30
So, length = 30 feet
Check Answer:
Length = 30 feet
so, width = 30 - 5 = 25 feet
so, area = 30 x 25 = 750 square feet

If y is inversely proportional to x, and y = 400 when x = 20, what is the value of y when x = 40 and x = 80?
A
400 and 100
B
200 and 100
C
250 and 480
D
500 and 200
Answer:
The correct answer is B. 200 and 100. When y is inversely proportional to x, it means that the ratio of x to y remains constant. In this case, when x = 20, y = 400, which means that the ratio of x to y is 20/400. Since the ratio is constant, we can use that ratio to find the values of y when x = 40 and x = 80. When x = 40, y = (20/400) x 40 = 200 and when x = 80, y = (20/400) x 80 = 100.

A population has a current size of 150. if λ is 1.2, what will the expected population size be after two generations? group of answer choices a. 144 b. 180 c. 200 d. 216
The expected population size after two generations is 216.
To calculate the expected population size after two generations using the given value of λ, we can use the formula:
[tex]Nt = N0 * lemda ^{t}[/tex]
where Nt is expected population size after t generations,
N0 is the initial population size, and lemda (λ) is the geometric growth rate.
Here, initial population size is N0 = 150, and the growth rate is λ = 1.2. We want to find the expected population size after two generations, so t = 2.
Putting these values into the formula, we get:
[tex]Nt = 150 * (1.2)^{2} \\Nt = 150 * 1.44\\Nt = 216[/tex]
Therefore, the expected population size after two generations is 216.

Philippa is making jam. She needs to buy mini jam jars which come in packs of 12, lids which come in packs of 16 and labels which come in packs of 36. She doesn't want to have any items left over. Find the smallest number of packs of each item she can buy
Philippa can buy 12 packs of mini jam jars, 9 packs of lids, and 4 packs of labels without having any items left over.
To find the smallest number of packs of each item Philippa can buy without having any items left over, we need to find the least common multiple (LCM) of 12, 16, and 36. The LCM is the smallest number that is a multiple of all three numbers.
We can find the LCM by listing the multiples of each number and finding the smallest number that appears in all three lists:
Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144...

Multiples of 36: 36, 72, 108, 144...
The smallest number that appears in all three lists is 144. Therefore, the LCM of 12, 16, and 36 is 144.
To find the smallest number of packs of each item Philippa can buy, we need to divide the LCM by the number of items in each pack:
Packs of mini jam jars: 144 ÷ 12 = 12
Packs of lids: 144 ÷ 16 = 9

In general, if the sample size is large, adding an extremely large outlier to a data set will not substantially affect sample mean. The correct option is (b) sample mean
The sample size is large, adding an extremely large outlier to a data set will not substantially affect the sample mean.
This is because the sample mean is a measure of central tendency that is influenced by all the values in the dataset, but it is more affected by the values that are closer to it in magnitude. When the sample size is large, the impact of any individual outlier on the overall mean is typically reduced, as the outlier will be more likely to be balanced out by the other values in the dataset.
However, the addition of an extremely large outlier may still have an impact on the sample standard deviation and median, depending on the magnitude and distribution of the other values in the dataset.
Therefore, the correct option is (b) sample mean

The formula below, Newton's law of cooling, allows us to calculate the temperature of an object as it cools.
T = R + (T0 − R)e-kt
T = temperature of the object after t minutes
T0 = initial temperature
R = temperature of the surroundings
k = cooling rate (depends on the object and conditions)
Suppose the temperature in Denver, Colorado was 55°F when a 5°F arctic cold front moved over the state. Using k = 0.012, how long would it take a puddle of water to freeze? (Recall that water freezes at 32°F.)
It would 51.35 minutes take a puddle of water to freeze.
What is the initial temperature?
Initial temperature refers to the average interior temperature of the coldest processing container at the start of the thermal processing cycle, as determined after a thorough stir or shake of the filled and sealed container.
The given equation is T = R + (T₀ − R)[tex]e^{(-kt)}[/tex].
T = temperature of the object after t minutes
T₀ = initial temperature
R = temperature of the surroundings
k = cooling rate (depends on the object and conditions)
The initial temperature is 55°F. The water freezes at 32°F. Thus final temperature is 32°F. The value of k is 0.012.
Now putting T = 32°F, T₀ = 55°F, R = 5°F, k = 0.012 in the given equation:
32 = 5 + (55 − 5)[tex]e^{(-0.012t)}[/tex]
Subtract 5 from both sides:
27 = 50[tex]e^{(-0.012t)}[/tex]
Divide both sides by 50:
[tex]e^{(-0.012t)}[/tex] = 27/50
Taking natural logarithms on both sides:
ln[tex]e^{(-0.012t)}[/tex] = ln(27/50)

Find and record the coordinates of the endpoints of AB and the lengths of the horizontal and vertical sides of the right
triangle.
It should be noted that point C is located at (2.6, 1.8).
How to explain the segmentThe length of horizontal side = (xB − xA) = 4 units
length of vertical side = (yB − yA) = 2 units
To find the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3, first convert the ratio between the parts into the fraction of the sum that the first part is equal to: a/a+b= 2/2+3= 2/5
Multiply the length of the horizontal side by the fraction, and then add the result to the x-coordinate of point A: Xc= Xa + (a/a+b) (Xb - Xa) = 1+ (2/5 x 4) = 2.6
Multiply the length of the vertical side by the fraction, and then add the result to the y-coordinate of point A: Yc= Ya + (a/a+b) (Yb - Ya) = 1+ (2/5 x 2) = 1.8
