Answer:
One is a set and another one is an ordered pair.
Step-by-step explanation:
Any set of numbers enclosed in curly brackets are considered sets while any two numbers enclosed by small brackets seperated by a comma are ordered pairs.
Answer:
x=-2
Step-by-step explanation:
Answer:
The greatest common factor of 42, 60 and 78 is 6.
Step-by-step explanation:
The given numbers are : 42, 60 and 78
On Prime Factorization of the given terms, we get:
42 = 2 x 3 x 7
60 = 2 x 2 x 3 x 5
78 = 2 x 3 x 13
The common factors to all these three terms is 2 x 3 = 6
Hence, the greatest common factor of 42, 60 and 78 is 6.
False.
In a random sample each member of the group has the same chances to be choosen. A representative sample replicates the characteristcs that you want of the group. Many times you need to make the sampling not random to pick a sample that represents or replicates the group.
Answer: Slope = -2.667/2.000 = -1.333
x-intercept = 5/4 = 1.25000
y-intercept = 5/3 = 1.66667
Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
