Answer:
6x-4
Step-by-step explanation:
Let's simplify step-by-step.
2(3x−2)−(4x−4x)
Distribute the Negative Sign:
=2(3x−2)+−1(4x−4x)
=2(3x−2)+−1(4x)+−1(−4x)
=2(3x−2)+−4x+4x
Distribute:
=(2)(3x)+(2)(−2)+−4x+4x
=6x+−4+−4x+4x
Combine Like Terms:
=6x+−4+−4x+4x
=(6x+−4x+4x)+(−4)
=6x+−4
Answer:
=6x−4
Answer:
False
Step-by-step explanation:
We are given the following in the question:
Pearson correlation = 1.30
Pearson coefficient:
- The range of Pearson coefficient is from [-1,1]
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Since, the given coefficient of Pearson does not lies in the range, it cannot express relation between two quantities.
Thus, a value of 1.30 does not indicates a strong correlation.
Thus, the given statement is false.
Answer:
256
Step-by-step explanation:
Raise 4 to the power of 4
Basically, multiply 4 by itself four times. :)
Answer:
(x - 1) (x + 4)
Step-by-step explanation:
x²+3x-4 = (x - 1) (x + 4)
