The median total of amount Franky earned is A = $81.67 per day.
Given data ,
For the first five days: $(100 + x) per day
For the next two days: $(175 + 2x) per day
For the final three days: $(75 + 2x) per day
Now , the average amount she earns is $80 per day
So , Average earnings = Total earnings / Total number of days
Average earnings = [(100 + x) * 5 + (175 + 2x) * 2 + (75 + 2x) * 3] / 10
Simplifying the equation:
80 = [500 + 5x + 350 + 4x + 225 + 6x] / 10
Multiplying both sides by 10:
800 = 1075 + 15x
Subtracting 1075 from both sides:
15x = -275
Dividing both sides by 15:
x = -18.33
For the first five days: $(100 - 18.33) = $81.67 per day
For the next two days: $(175 + 2*(-18.33)) = $138.34 per day
For the final three days: $(75 + 2*(-18.33)) = $38.34 per day
Arranging the earnings in ascending order: $38.34, $38.34, $38.34, $81.67, $81.67, $81.67, $81.67, $138.34, $138.34
The median is the middle value when the earnings are arranged in ascending order. In this case, the middle value is $81.67
Hence , the median is $81.67

What are the slopes of the point o,2 1 , -1
The slope of the line that goes through the points (0, 2) and (1, -1) is -3.
What is the slope of the line?
The slope of a line is a number that describes the steepness of a line and the direction it is heading. It is also known as the "rise over run" or the "rate of change" of a line. The slope of a line is typically represented by the letter "m" and is found using the formula:
slope = (y2 - y1) / (x2 - x1)
To find the slope of a line, you need two points on the line (x1, y1) and (x2, y2) and substitute their coordinates into the slope formula.
To find the slope of a line, we use the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, we have two points: (0, 2) and (1, -1). To find the slope between these two points, we can substitute their coordinates into the slope formula:
slope = (-1 - 2) / (1 - 0)
slope = -3
Hence, the slope of the line that goes through the points (0, 2) and (1, -1) is -3.

What is slope?
An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). The ratio of how much y grows as x grows by a certain amount is known as the slope of a line. A line's slope, or the amount by which y rises as x rises, indicates how steep a line is. The slope is constant (the same) along the line.
Here from given tables lets take any two points to find slope, then
[tex](x_1,y_1)=(0,-6) and (x_2,y_2)=(1,0)[/tex]
Now using slope formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] then
=> m = [tex]\frac{0-(-6)}{1-0}[/tex]

what are the coorindates of point A
Point A has coordinates (x1, y1). The x-coordinate, x1, is the horizontal distance from the origin, while the y-coordinate, y1, is the vertical distance from the origin.
What are coordinates?Coordinates in math refer to a pair of numbers that indicate the position of a point on a two-dimensional graph or in a three-dimensional space. The two numbers are usually referred to as the x-coordinate (or abscissa) and the y-coordinate (or ordinate). In three-dimensional space, the third number is referred to as the z-coordinate (or applicate). A point located at (3, 4) on a two-dimensional graph would be located 3 units along the x-axis and 4 units along the y-axis. Similarly, a point located at (3, 4, 5) in three-dimensional space would be located 3 units along the x-axis, 4 units along the y-axis, and 5 units along the z-axis.
Both coordinates indicate the exact location of Point A in a coordinate system. For example, if Point A is located at (2, 4), it means that the x-coordinate of Point A is 2, which is 2 units away from the origin in a horizontal direction, and the y-coordinate of Point A is 4, which is 4 units away from the origin in a vertical direction. The origin is usually located at (0, 0) in a coordinate system.

Before I solve the system, I am going to rewrite it to make it easier for me to understand it.
[tex]y=(x-3)^2+1\\y=-3x+10[/tex]
Notice that f(x) and g(x) have been changed into y. The reason is because f(x) and g(x) are the same and stand for y, but we only use f and g to distinguish between the 2 equations. We can use equal values to solve.
[tex](x-3)^2+1=-3x+10[/tex] [exponent]
[tex]x^2-6x+9+1=-3x+10[/tex] [add both sides by 3x]

[tex]x^2-3x=0[/tex] [factor]
[tex]x(x-3)=0[/tex]
Notice that x=0 and x-3=0. This means the solutions are x=0 and x=3.

A system of linear inequalities represented by the graph are;
Inequality 1: y ≤ 3x - 3
Inequality 2: y ≥ ¹/₂x - 3
How to interpret Inequality Graphs?Inequalities that use < or > symbols are usually plotted with a dashed line that shows us that the line is not included in the region. Meanwhile, Inequalities that use ≤ or ≥ symbols are normally plotted with a solid line that shows us that the line is included in the region.
The general formula of equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Thus, the graph that rises to the right side in the first quadrant has;
Slope = (3 - 1)/(3 - 2)
Slope = 3
the y-intercept is at y = -3
Thus, equation is;
y ≤ 3x - 3
Thus, the graph that rises to the left side in the second quadrant has;
Slope = (1 - 0)/(2 - 0)
Slope = 1/2
the y-intercept is at y = 1

How many children and how many adults swam at the public pool that day?
Using substitution method to solve the system of linear equation, the number of children is 90 and adults is 93.
What is System of Linear EquationIn mathematics, a system of linear equations is the collection of two or more linear equations that share the same variables. The maximum power of the variable in the linear equations in this situation is 1, making them first-order equations. A linear equation may have one, two, or three variables. We can therefore create linear equations with n variables.
To solve this problem, we have to define our variables and then write the equations.
Let;
x = childreny = adultx + y = 183 ...eq(i)
1.75x + 2.5y = 390 ...eq(ii)
solving both equations
From equation (i)
x + y = 183
x = 183 - y ...eq(iii)
Put equation (iii) into equation (ii)
1.75(183 - y) + 2.5y = 390
y = 93
Put y = 93 into equation (i)
x + 93 = 183
x = 90
The number of child is 90 and adult is 93

Step-by-step explanation:
The triangle shown in the image is a right triangle.
The missing side, x, is the leg and its length is equal to other leg because this is also an isosceles triangle. So this triangle is special 45°-45°-90° and the side lengths are represented with a-a-a√2 respectively. The length of hypotenuse is equal to √8 so:a√2 = √8
Divide both sides by √2a = √4
Remember we said a represents legs, in the image x represents the legs so the answer is:
x = √4 and √4 = 2, therefore the answer is 2.

The probability of selecting a student from the class who is a pet owner or prefers cats to dogs is; 0.4
What is the probability of selection?In probability, If events A and B are not mutually exclusive, then the probability of A or B is expressed as;
p(A or B) = p(A) * p(B).
Total number of students = 26
Total number of students that are pet owners = 18
Total number of students that prefers cats to dogs = 26 - (8 + 3) = 15
Thus;
P(pet owner) = 18/26
