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.
9513 rounded to the nearest thousandth is 10,000.

Answer:
103.18units³
Step-by-step explanation:
Area of the sector DEF = theta/360 * πr²
r is the radius
theta is the angle subtended at the centre
theta =70 degrees
radius DE = 13units
Substitute
Area of the sector = 70/360 * 3.14(13)²
Area of the sector = 7/36 * 530.66
Area of the sector = 3,714.62/36
Area of the sector = 103.18units³ (to the nearest hundredth)
