Include your scatter plot and the answers to the following questions in your word processing document.
1. Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to
determine the slope and how the equation was determined,
3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4. Test the residuals of two other points to determine how well the line of best fit models the data
5. Use the line of best fit to help you to describe the data correlation.
6. Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arm span is 66 inches?
7. According to your line of best fit, what is the arm span of a 74-inch-tall person?
Answer:
ok so 6 is connected to question 2, question 4 is asking two other points to determine how it will fit best in the models, question 5 use the line of the best fit to help u describe the data correlation, and question 7 it is jus asking wht the arm span of a 74inch tall person so jus figure the arm span yk (hope this helps)

What is the exact value of x? 5⋅21^5x=16
Answer:
x= 16 /20420505
Step-by-step explanation:
Let's solve your equation step-by-step.
5(215)x=16
Step 1: Simplify both sides of the equation.
20420505x=16
Step 2: Divide both sides by 20420505.
20420505x /20420505 = 16 /20420505
x= 16 /20420505

Adult tickets for the school musical are sold for $3.50 and student tickets are sold for $2.50 on a given night 425 tickets were sold for $ 1237.50. Wrote a system of linear equations for the problem
Answer:
3.5x + 2.50y = 1237.50
425 = x + y
Step-by-step explanation:
number of adult tickets: x
number of student tickets: y
3.5x + 2.50y = 1237.50
( value of adult ticket [3.50]* number of adult tickets [x]) + (value of student ticket [2.50] * number of student tickets [y]) = total value (1237.50)
425 = x + y
(number of adult tickets [x]) + (number of student tickets [y]) = total (425)

Which of the following statements are true about inverse matrices?
All square matrices have inverses.
If A and B are inverse matrices, then A and B must be square matrices.
The determinant of a singular matrix is equal to zero.
If A and B are inverse matrices, then A + B = I.
If A and B are inverse matrices, then det(A)xde(B)=0
Any zero matrix does not have an inverse.
If B = A–1, then A = B–1.
B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.
what is matrix ?An arrangement of integers in both columns and rows is known as a matrix. learns about matrices' components and dimensions and first presents them. A matrix is a rectangular grid with integers arranged in rows and columns.
The statements that are true about inverse matrices are:
Not all square matrices have inverses. A square matrix only has an inverse if its determinant is not equal to zero. If the determinant of a square matrix is zero, it is called a singular matrix and does not have an inverse.
If A and B are inverse matrices, then A and B must be square matrices. This is because only square matrices can have inverses.
The determinant of a singular matrix is equal to zero. This is because the determinant of a matrix is related to the linear independence of its columns or rows. A singular matrix has linearly dependent columns or rows, which means its determinant is zero.
If A and B are inverse matrices, then A + B = I. This is not necessarily true. In general, the sum of two inverse matrices is not necessarily the identity matrix.
If A and B are inverse matrices, then det(A) x det(B) = 1. This statement is almost true, but the correct statement is det(A) x det(B) = det(AB) = 1.
Any zero matrix does not have an inverse. This is because the determinant of a zero matrix is zero, and therefore it is singular and does not have an inverse.
If B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.

How many glasses of water can be filled with 3 1/2. bottles of water?
Answer:
21 glasses
Step-by-step explanation:
6 glasses in a bottle
3 x 6 = 18
3 glasses in half a bottle
18 + 3 = 21
Answer:
21 glasses
Step-by-step explanation:
let 'g' = glasses of water
create a proportion, glasses over bottles equals glasses over bottles
1 = g
