Tony has 43 minutes between the end of the project and the beginning of band practice.
First take out the GCF
-3x(x^2-5x-14)
-3x(x-7)(x+2)
-7+2=-5
-7*2=-14
Answer: D
Answer:
A and C
Step-by-step explanation:
Well, the largest set it belongs to is the set of all real numbers - numbers which can be written on the number line. -5 is of the set of rational numbers since it can be written as a fraction (-5/1 for example). It is an integer since it is a whole number. Thus:
-5 ∈ <span> ℤ (</span>Integers) ∈ ℚ (Rational Numbers) ∈ <span>ℝ (Real Numbers)</span>
Answer: Median: 3 is the closest to the most numbers in the set
Explanation: The mean is (4+19+3+3+2+3+2+4)/8 = 5
The median is the middle of (2, 2, 3, 3 here 3, 4, 4, 19) = 3
