The mean of the salary is $120000.
By adding up a list of salaries and dividing by the total number of salaries on the list, mean salaries are derived. This means that exceptionally high and extremely low incomes have the same weight in the final average, which is crucial to bear in mind while investigating industry salaries.
By ranking the wages of a group of employees in descending order, you may determine the median base salary by finding the income that is in the middle of the distribution.
Mean=(5*440,00+2*100,000+1*540,000)/(5+2+1)
=(220,000+200,000+540,000)/8
=960,000/8
=120,000
Median is 100,000.
Hence, the mean salary is 120,000 but 7/8 members salary is lower than 120,000. Because the firm’s owner salary is too high. thus the firm’s owner is so unethical regarding employee salary.

1. Mrs. is selling tickets to a school carnival fundraiser. Adult tickets are $5 and student tickets
are $3. At the end of the fundraiser, she had made $521 and had sold a total of 145 tickets. How
many student tickets did she sell?
Taking into account the definition of a system of linear equations, she sold 102 student tickets.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
This caseIn this case, a system of linear equations must be proposed taking into account that:
A: number of adults tickets sold.S: number of students tickets sold.Knowing that:
Adult tickets are $5 and student tickets are $3. At the end of the fundraiser, she had made $521 and had sold a total of 145 tickets.the system of equations to be solved is
[tex]\left \{ {{A+S=145} \atop {5A+3S=521}} \right.[/tex]
Of the multiple methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable A from the first equation:
A= 145 - S
Replacing this expression in the second equation:
5(145 - S) + 3S= 521
5×145 - 5S + 3S= 521
725 - 5S + 3S= 521
-5S + 3S= 521 - 725
-2S= -204
S= (-204)÷(-2)
S= 102
Finally, she sold 102 student tickets.

Which line is perpendicular to 3 x+2 y=6 ?
(A) 4x - 6y = 3
(B) y = -(3/2)x + 4
(C) 2x + 3y = 12
(D) y = (3/2)x+1
The equation of the line 3x + 2y = 6 is perpendicular with the equation of the line (A) 4x - 6y = 3.
Two lines are perpendicular with each other if they form right angle at the point of their intersection. The slopes of perpendicular lines are negative reciprocal of one another.
The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.
In an equation in standard form, ax + by = c, the slope, m, of the line is equal to a/b. On the other hand, in an equation in slope-intercept form, y = mx + b, m is the slope.
Determine the slope of the given line and each given choices:
3x + 2y = 6
m = a/b = 3/2
(A) 4x - 6y = 3
m = a/b = 4/-6 = -2/3
(B) y = -(3/2)x + 4
m = -3/2
(C) 2x + 3y = 12
m = a/b = 2/3
(D) y = (3/2)x + 1
m = 3/2
Since the slope of the given line is 3/2, taking its negative reciprocal, the slope of the perpendicular line should be -2/3. The line with the slope of -2/3 is (A) 4x - 6y = 3.
Hence, (A) 4x - 6y = 3 is perpendicular with 3x + 2y = 6.

Hector's school is holding a fitness challenge. Students are encouraged to exercise at least 2 1/2 hours per week. Hector exercises about the same number of hours each week. During a 4-week period, he exercises for 11 1/2 hours. Hector wants to compare his exercise rate with the fitness challenge rate.
Hector outperformed the challenge rate as he exercised 2.88 hours a week.
It is best to convert the mixed fraction to decimals for easier calculation.
The students are encouraged to exercise 2¹/₂ hours per week. In decimals this is:
= 2 + ¹/₂
= 2 + 0.5
= 2.5 hours per week
In the 4 week period, Hector exercised 11¹/₂ hours which is:
= 11 + ¹/₂
= 11 + 0.5
= 11.5 hours
The number of hours he exercised per week is:
= Number of hours in total / Number of weeks
= 11.5 / 4
= 2.88 hours per week
When compared to the fitness challenge rate, we can conclude that Hector outperformed the challenge rate

Alejandro made his first error in which step?
Step 1
Step 2
Step 3
Step 4
Alejandro stated -4/3 instead of -3/4 as the slope of the perpendicular line in step 2, therefore, his first error is in step 2.
What are the Equations of Perpendicular Lines?For any two given perpendicular lines, they must have slope (m) values that are negative reciprocals of each other. The equation of any line can be written in slope-intercept form as, y = mx + b, where m is the slope of the line.
Given the equation, 4x - 3y = -8, rewrite in slope-intercept form:
-3y = -4x - 8
-3y/-3 = -4x/-3 - 8/-3
y = 4/3x + 8/3
This means that the line has a slope of 4/3. Thus, the slope of the line that is perpendicular to the given line would be the negative reciprocal of 4/3, which is: -3/4.
Thus, we can see that Alejandro stated -4/3 instead of -3/4 as the slope of the perpendicular line in step 2, therefore, his first error is in step 2.

The weight of Christensen's family's kitten is 9 pounds 3 ounces.
The imperial unit of mass or weight measurement is the pound. The symbols for pounds are lb and lbm. A kilogram weighs 0.4535 pounds. The term "pound" has Germanic roots.
In the conventional system of measurement, a pound is a unit of weight. 16 ounces make up one pound.
Therefore,
We know that 1 pound = 16 ounces
16 ounces = 1 pound
Dividing each side by 16.
( 16 / 16) ounces = ( 1/16 ) pound
1 ounce = ( 1/16 ) pound
Multiplying each side by 147,
1 ounce × 147 = ( 1/16 ) × 147 pound
147 ounces = ( 147 / 16 ) pounds
147 ounces = 9.1875 pounds
147 ounces = 9 + 0.1875 pounds

You can formulate the postulate as:
x² + (x + 2)² + 15 = (x + 4)²
Which simplifies to x² - 4x + 3 = 0, with solutions x=1 and x=3
so 1, 3 and 5 must be the other tuple.

f(x)=|x|+5 horizontal shrink of factor 3
The function that models the horizontal shink of f(x) by a scale factor k = 3 is:
g(x) = |3*x| + 5
How to apply a horizontal shrink to the given function?Here we want to apply a transformation to a given function where the transformation is a shrink.
For a function f(x), a horizontal shrink (or compression) of scale factor K is written as:
g(x) = f(k*x)
In this case we have the absolute value function:
f(x)= |x| + 5
And we want to apply an horizontal shrink of scale factor k = 3, so we will have a new function defined as:
g(x) = f(3*x)
If we replace f(x) by the function above we will get:
g(x) = f(3*x) = |3*x| + 5
So we conclude that the transformed function is just:
g(x) = |3*x| + 5

What is a percentage error?Percentage error is the ratio of the difference between estimated value and the actual value to the actual value expressed as a percentage.
7) a) The Einstein mass energy relation is presented as follows;
E = m•c²
The speed of light, c = 3×10⁸ m/s
The mass, m = 1 kg, gives;
E = 1 kg × (3×10⁸ m/s)² = 9.0 × 10¹⁶ Joules
The energy present in 1 kg. mass is; 9.0 × 10¹⁶ Joulesb) Energy consumption of the light bulb = 60 J/sec
The duration, t, the light bulb will remain lit is therefore;
t = (9.0 × 10¹⁶)/(60) = 1.5 × 10¹⁵ s ≈ 47533146.96 years8) Percentage error, %error, is found as follows;
%error = ((Approximate value - Actual value)/(Actual value)) × 100
Appreciate value = 46,620 km
Actual value = 40,030.2 km
Which gives;
%error = ((46,620 - 40,030.2)/(40,030.2))×100 ≈ 16.46%

The observed error in the calculation = 22.6%
Required; The two possibilities for the correct kinetic energy
Solution;
E% = ((Approximate value - Actual value)/(Actual value)) × 100
Taking the calculated value as the approximate value, and the correct value as the actual value, we have;
22.6% = ((74.9 - Actual value)/(Actual value)) × 100
(22.6/100)×Actual value = 74.9 - Actual value
Actual value + 0.226×Actual value = 74.9
