the mean (average) can be found by adding up all the numbers and dividing that by how many numbers there are.
The mean of this data set is : 405/15 = 27
the mode is the number that appears most often in ur data set
so the mode is : 15
the range is the highest number - the lowest number
the range is (45 - 15) = 30
the median is ur middle number
the median is : 24
ascending order (smallest to largest) is : mode, median, mean, range
The equivalent expression of 9q^ 2 - 2/3(3q - 7) + 5q^2 is 14q^ 2 - 2q - 14/3
<h3>How to determine the equivalent expression?</h3>
The expression is given as:
9q^ 2 - 2/3(3q - 7) + 5q^2
Open the bracket
9q^ 2 - 2q - 14/3 + 5q^2
Evaluate the like terms
14q^ 2 - 2q - 14/3
Hence, the equivalent expression of 9q^ 2 - 2/3(3q - 7) + 5q^2 is 14q^ 2 - 2q - 14/3

Answer:
B
Step-by-step explanation:
Answer B is the result of simplifying
B - 63 Degrees, obviously because all angles add up to a sum of 180 degrees.
