Answer: 9</h2>
Step-by-step explanation:
I like to write out a multiplication of the lowest factors for each of the numbers and then compare them to find what might be the Greatest Common Factor.
Now,
36 = 2 × 2 × <u>3 × 3</u>
45 = <u>3 × 3</u> × 5
63 = <u>3 × 3</u> × 7
∴ the GCF is 9.
Answer:
the answer is c
Step-by-step explanation:
Answer:
Infinite Parallel lines can be drawn to a general straight line.
Step-by-step explanation:
Given:
which is in the general form of a straight line that is
where m is the slope and c is the constant
Infinite Parallel lines can be drawn to a general straight line.
Let we see graphically,
So to draw any straight line minimum two points we require.
so put
similarlly,
so the 2 points are (0,10) and (-2,0)
Answer:
d. No, you should examine the situation to identify lurking variables that may be influencing both variables
Step-by-step explanation:
Hello!
Finding out that there is a regression between two variables is not enough to claim that there is a causation relationship between the two of them. First you have to test if other factors are affecting the response variable, if so, you have to control them or test how much effect they have. Once you controled all other lurking variables you need to design an experiment, where only the response and explanatory variables are left uncontroled, to learn if there is a regression and its strenght.
If after the experiment, you find that there is a significally strog relationship between the variables, then you can imply causation between the two of them.
I hope it helps!
