Answer:
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
Step-by-step explanation:
A square matrix is where the number of rows is equal to the number of columns like order 2x2, 3x3, 4x4, 5x5 etc.
Given options are:-
A) A shoe salesperson wants to use an augmented matrix to represent the quantity of children’s shoes and adult shoes sold at his store for two days.
It is 2x2 times 2x1 = 2x1 matrix.
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
It is 6x1 times 1x6 = 6x6 matrix.
C) A student wants to write a coefficient matrix representing a linear system with two equations and three unknowns.
It is 2x3 times 3x1 = 2x1 matrix
D) A teacher wants to write an augmented matrix representing a linear system with four equations and four unknowns.
It is 4x4 times 4x1 = 4x1 matrix.
Hence option B is correct.
Answer:
Scatter plots can be a little confusing, but all you need to do is look for an association (what direction the dots appear to be going in). Positive association resembles this / whereas negative association resembles this / flipped the other way. It could also be a curved line, which would be a nonlinear association. If it appears to have no direction at all it has no association. Other wise, all you have to do is read the data to answer the questions. e.g. for the first question find the highest score in the right side of the table and then the corresponding number in the left side. Hope this helps!
The hypotenuse is the longest side of the triangle and also the one that is across from the ninety degree angle.
The integers would be 1, 2, and 3!
1+2+3 is equal to 6, and 2(3)=6 as well. Hope this helped :)
