It would be A, most definitely.
<u>Answer-</u>
<em>A. strong negative correlation.</em>
<u>Solution-</u>
<u>Direction of a relationship</u>
- Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
-
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)
<u>Strength of a relationship</u>
- Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
- No relationship- When two variables have no relationship at all, their correlation is 0.
As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.
It is my opinion that it is C) but i am not sure, you might be correct though...
Answer:
3(-x^2-6x+4)
Step-by-step explanation:
-3x^2 - 18x + 12
-3x^2 - (2 x 3^2) x + 2^2 x 3
3 (-3x^2 over 3 - 2x3^2 times x over 3 + 262 x 3 over 3)
3(-(x^2) - (2 x 3^2-1 times x) +2^2
3(-x^2 - (2 times 3x) +4)
3(-x^2-(6x) + 4)
3(-x^2 - 6x + 4)
Answer:
18x+y=-52
Step-by-step explanation:
we all know and love(being 100% sarcastic here)the standard form as
ax+by=c
y=-9(x+3)*2+2----This is weird and not so nice
so lets make it nice by distributing the 9::::
y=(-9x-27)2+2
and now the 2:
y=-18x-54+2
y=-18x-52
oops this is NOT in S.F we got to switch the -52 and y
52=-18x-y
-18 cant be neg. so we have to divide by -1 on both sides
-52=18x+y
18x+y=-52
HOPE THIS HELPS
