x^2-16 factors to (x-4)(x+4)
You use the difference of squares rule here which is
a^2 - b^2 = (a-b)(a+b)
Answer:
0.02612898 m2 ( im so sorry if this is wrong im new at this =))
Step-by-step explanation:
((3/8) foot) x (3/4) foot =
0.02612898 m2
Answer: y=-4x+13
Explanation : because it is :)
Step-by-step explanation:
For 2 lines to form a system with no real solution, the slope of the lines have to be equal and the y-intercept is different.
Hence the answer is y = 5(x + 2).
Answer:
(d) WEAK NEGATIVE ASSOCIATION.
Step-by-step explanation:
Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.
Here, r = -0.19
Now, as r is NEGATIVE.
⇒ As the value of x increases , value of y decreases.
⇒There is a NEGATIVE ASSOCIATION.
Now as the value of r is between 0 and ( -1). So the factor of variation is very small.
Hence, it is WEAK NEGATIVE ASSOCIATION.
