How to find the amount Mr Kepler paid for the tool, not including taxGiven that:
with a discount of 40% off the regular price
The regular price was $200
A discount of 40% is given to Mr Kepler. Discount represents amount less the total amount. At a 40% discount Mr Kepler paid 60%
40% = 0.4
40% discount = 1 - 0.4 = 0.6 (equivalent to 60%)
The amount Kepler paid

Knowledge of percentage is used here and the amount Mr Kepler paid is $120 not including tax
34% of 850
The statement 34% of 850 means 34 divided by 100 multiplied by 850. The division by hundred takes care of the percent, then "of" means multiplication
34% = 0.34
0.34 * 850 = 289

The median of the data is 110.The data has a range from 150 to 40, with a peak at 80 and gaps at 50 and 60. The median of the data is 100.
Answers
Looking at the graph, the minimum value is 40 and the maximum value is 150, therefore the range is between 150 and 40.
Also, we have a total of 27 points on the graph, which means the median is the 14th value of the data set in crescent order.
Counting the points from the left to the right, the 14th point has a value of 100, therefore the median is equal to 100.

h(r) = (r +1)(r+8)1) What are the zeros of the function?Write the smaller r first, and the larger second.smaller r =larger s 2) What is the vertex of the parabola
Answers
For the zeros of the function, we have to solve h(r)=0, therefore:
[tex]\begin{gathered} h(r)=(r+1)(r+8) \\ h(r)=0 \\ \Rightarrow(r+1)(r+8)=0 \\ \Rightarrow r=-1\text{ or } \\ r=-8 \end{gathered}[/tex]then, the smaller r is -8 and the larger is -1.
Now, to find the vertex of the parabola, we can find the x-coordinate of the vertex from the general rule:
[tex]\begin{gathered} f(x)=ax^2+bx+c \\ \text{ x-coordinate: -b/2a} \end{gathered}[/tex]In this case, we have the following:
[tex]\begin{gathered} h(r)=(r+1)(r+8)=r^2+8r+r+8=r^2+9r+8 \\ \Rightarrow a=1,b=9 \\ \Rightarrow-\frac{b}{2a}=-\frac{9}{2(1)}=-\frac{9}{2} \end{gathered}[/tex]now that we have the x-coordinate of the vertex, we just evaluate the function on that point to find the y-coordinate of the vertex:
[tex]h(-\frac{9}{2})=(-\frac{9}{2}+1)(-\frac{9}{2}+8)=(-\frac{7}{2})(\frac{7}{2})=-\frac{49}{4}[/tex]therefore, the vertex of the parabola is the point (-9/2,-49/4)

On a number line, the numbers are arranged in order at regular intervals along its length.It often appears horizontally and could extend indefinitely in either direction. A number line is a horizontal line with consistently spaced numerical increments.How the number on the line can be answered depends on the numbers that are present. Given, the elevation indicates that New Orleans is 2 feet below (lower than) sea level.The elevation of Salton City is lower than that of New Orleans. Required; potential rise of Salton CitySalton City's elevation can be calculated using the information below on a number line: We have;& |t; |-3 |-2 |0 > if SL stands for sea level, N for New Orleans, and S for Salton City. On the number line above, a S. N. SLA point to the right of the -2 mark denotes an elevation that is higher than New Orleans, and a point to the left of -2 denotes an elevation that is lower than New Orleans.Therefore,
Salton City should be located to the left of -2, which is a point, at a distance of x -2 feet.
Salton City's elevation, which is determined by the set x -2 feet, is less than 2 feet above sea level.

In other words, a composite function is generally a function that is written inside another function.
Therefore, the composite function can be solved as follows:
Therefore,
f(x) = x - 8
g(x) = 8x + 9
Hence,
(f + g)(x) = f(x) + g(x) = x - 8 + 8x + 9 = 9x + 1
(f - g)(x) = f(x) - g(x) = x - 8 - ( 8x + 9 ) = x - 8 - 8x - 9 = -7x - 17
(f. g)(x) = f(x) . g(x) = (x - 8)(8x + 9) = 8x² + 9x - 64x - 72 = 8x² - 55x - 72
(f / g)(x) = f(x) / g(x) = x - 8 / 8x + 9

Step-by-step solution:
As we are given that K and L are the midpoints of FG and FH respectively.

The scatter plot shows students scores for quiz 1 and quiz 2. a. What is the quiz 1 score for a student who earned a score of 13 on quiz 2? b. Did any student(s) earn the same score on both quiz 1 and quiz 2? Explain. c. The dotted line shows the line of best fit. Write its equation and then interpret the meaning of the slope and y-intercept. Does the y-intercept make sense in the context of the problem? The slope should be represented as a fraction or whole number just to let you know. Here is a picture attached of the graph.
Answers
b) Looking at the graph, the scores of quiz 2 are on the y axis while the scores of quiz 1 are on the y axis. Each samll box on both axes is 2 units. This means that half of a samll box is 1 unit. We can locate a score of 15 in quiz 2(halfway between 14 and 16). It also corresponds to a score of 15 in quiz 1. Thus, 1 student earned 15 marks in quiz 1 and 2
c) The equation of the line of best fit is written in the slope intercept form which is expressed as
y = mx + b
where
m = slope
b = y intercept
We would calculate the slope by applying the formula,
m = (y2 - y1)/(x2 - x1)
where
y1 and y2 are y coordinates of initial and final points on the line.
x1 and x2 are x coordinates of initial and final points on the line.
Picking points on the graph, we have
when x1 = 10, y1 = 8
when x2 = 16, y2 = 14
By substituting these values into the formula,
m = (14 - 8)/(16 - 10) = 6/6 = 1
We would find the y intercept by substituting m = 1, x = 10 and y = 8 into the slope intercept equation. We have
8 = 1 * 10 + b = 10 + b
b = 8 - 10
b = - 2
Substituting m = 1 and b = - 2 into the slope intercept equation, the equation of the line of best fit is
y = x - 2
The slope is 1 and since it is small, it tells us that for each score of 1 that a student gets in quiz 2, he would likely get a score of 1 in quiz 1.
Since the y intercept is negative, it doesn't make sense in the concept of the problem because a student cannot earn a negative score in any of the quizzes. The y intercept tells us that the student earned - 2 in quiz 2 and 0 in quiz 1

Given,
Bartlett Electronics pays all sales representatives 4% commission on the first $35,000 of their individual sales and 7% commission on their individual sales in excess of $35,000.
John Morgan sold merchandise valued at $73,500 during the month of November.
Here we need to find the following:
a) Commission on sales in the sales base
b) Commission on additional sales
c) Gross pay
a) Commission on sales in the sales base
So, based on the percentage the commission is,
=> 35,000 x 4/100
=> 35,000 x 0.04
=> 1400
b) Commission on additional sales
For this one, first we have to calculate the additional sales amount,
That can be calculated as,
=> 73,500 - 35,000
=> 38,500
Now, the commission is,
=> 38,500 x 7/100
=> 38,500 x 0.07
=> 2695.
c) Now the gross pay for John is,
=> 1400 + 2695
=> 4095
Therefore, the gross pay is $4095.
