What is meant by ordered pair?A pair that has two values stated in a specific order between parenthesis is known as an ordered pair. It is made up of the x coordinate (abscissa) and the y coordinate (ordinate). For greater visual comprehension, it helps to locate a point on the Cartesian plane. An ordered pair of numbers can have either fractional or integer values.Ordered pairs are a common representation for two variables. We mean x = 7 and y = -2 when we write (x, y) = (7, -2). The term "x-coordinate" refers to the number that relates to the value of x, and the term "y-coordinate" refers to the number that relates to the value of y.N's coordinates are: (-2,-6)
To create point N', point N is reflected over the y-axis.
Point N is then created by reflecting point N' over the x-axis ".
To locate: The ordered pair describing N's location ".
Solution:
Point N's coordinates are (-2,-6). To create point N', point N is reflected over the y-axis.
[tex]& (x, y) \rightarrow(-x, y) \\[/tex]
[tex]& N(-2,-6) \rightarrow N^{\prime}(2,-6)[/tex]
Point N is then created by reflecting point N' over the x-axis.
[tex]& (x, y) \rightarrow(x,-y) \\[/tex]
[tex]& N^{\prime}(2,-6) \rightarrow N^{\prime \prime}(2,6)[/tex]

John has 6 quarters, 12 nickels, and 6 dimes, for a total of 24 coins. This is because he has twice as many nickels as quarters (12 nickels, 6 quarters), and two more dimes than nickels (12 nickels, 6 dimes). With this combination, the total value of all the coins would be $3.50.
To calculate the number of coins John has, we can use the following steps:
Calculate the total value of the coins: 3.50Divide the total value of the coins by the value of each coin type: a. Quarters: 3.50 / 0.25 = 14 b. Nickels: 3.50 / 0.05 = 70 c. Dimes: 3.50 / 0.10 = 35Since John has twice as many nickels as quarters and two more dimes than nickels, we can set up the following equation: 2x + x + 2 = 70Solve the equation: x = 6Calculate the number of coins of each type: a.

129 students had a private scholarship.
Out of the 843 students,
112 had a private scholarship17 had both government and private scholarships209 had only one of the two scholarships.To calculate the total number of students with a private scholarship, we need to add the number of students who had a private scholarship (112) and the number of students who had both scholarships (17). This gives us a total of 129 students with a private scholarship. The rest of the students, who had either a government scholarship (80) or no scholarship (651), do not have a private scholarship.
209 students had only one of the two scholarships, so 209 - 129 = 80 students had a government scholarship.
So in total, 112 + 80 = 192 students had either a private or a government scholarship.
Therefore, 843 - 192 = 651 students did not have either a private or a government scholarship.

a chef Cuts 3/4 lb of cheese. he put aside 1/8 of the cheese to top his lasagna. how much cheese will he put on top
Answer:
Step-by-step explanation:
There are 16 ounces in 1 pound. Take 3/4 and multiply it by 16.
3/4 x 16 ounces = 12 ounces
There are 12 ounces in 3/4 lb.
The chef uses 1/8 of the 12 ounces (or 3/4 lb) of cheese for the top of the lasagna.
1/8 of 12 ounces
1/8 x 12 ounces = 1.5 ounces
The chef uses 1.5 ounces for the top of the lasagna.
To convert the ounces to pounds, use 1 lb/16 ounces. The ounces cancel and you are left with pounds.
1.5 ounces x (1 lb/16 ounces) = 0.09375 lb

calculate r-squared,--the coefficient of determination--given that the linear correlation coefficient, r, is 0.817. what does this tell you about the explained variation and the unexplained variation of the data about the regression line?
R-squared is calculated as the square of the linear correlation coefficient (r). In this case, the linear correlation coefficient is 0.817, so the R-squared can be calculated as follows:
R-squared = r^2 = 0.817^2 = 0.67
R-squared measures the proportion of variation in the dependent variable that is explained by the independent variable in a regression analysis. A value of R-squared close to 1 indicates that a large proportion of the variation in the dependent variable is explained by the independent variable, while a value close to 0 indicates the opposite.
In this case, a value of 0.67 for R-squared indicates that 67% of the variation in the dependent variable is explained by the independent variable, while the remaining 33% is unexplained.

TRIGONOMETRY QUESTION-
alright my friend and i have been stuck on this FOREVER!
use properties of similar triangles to find the value of "x" and the length of the sides involving "x".
in this situation we are given two triangles, triangle ABC to triangle FEG (in that order, its weird, i know).
A = 5 F = 2x
B = x+4 E = 18
C = ? G = ?
I know usually you would set up the proportions, however when i do that i get 90=2x^2+8x, and i dont think i should be using the quadratic equation to find the side of a triangle. What is my best method of approach? if you leave the answer, please let me know how you did it!
You were on the right track, I totally understand why you'd get stuck where you are currently in the process. To start with, you technically found the wrong ratio between the two triangles. Your ratio is just 2x, while it should be 2x/5.
To start, let's find the ratio between triangle FEG and ABC by dividing angle F by and A:
[tex]R=\frac{2x}{5}[/tex]
Now, multiply angle B by this ratio:
[tex](x+4)(\frac{2x}{5} )=\frac{2x^2}{5}+\frac{8x}{5}=\frac{2x^2+8x}{5}[/tex]
We can now set this expression equal to angle E, as we have multiplied by the common ratio:
[tex]\frac{2x^2+8x}{5} =18[/tex]
This looks rather daunting, but let's keep calm... you can do this!!
Start by subtracting 18 from both sides:
[tex]\frac{2x^2+8x}{5}-18=0[/tex]
Now, let's get the whole expression under the denominator 5:
[tex]\frac{2x^2+8x-90}{5}=0[/tex]
Notice that the denominator can now be removed:
[tex]2x^2+8x-90=0[/tex]
Now, factor the equation (you could also use the quadratic eq if you want)
[tex]2(x-5)(x+9)=0[/tex]
Notice that we have two potential values for x (5 and -9).
Think about this logically... If we use -9 and plug it in for x, we will end up with values of -5 degrees for an angle, which is impossible! Therefore 5 is the only valid answer!
I encourage you to also approach the problem from a different angle and use the common factor (5/2x) and multiply it by 18 :)
