The best answer to the statistics question above would be letter A. The r-value that represents the strongest negative correlation among the given choices would be -0.7. This is because the magnitude of the correlation ranges from .7 to .9 which indicates a strong correlation. The negative sign connotes the negative relationship.

Answer:
y = 3x^2 +30x +69
Step-by-step explanation:
Transformations work this way:
g(x) = k·f(x) . . . . vertical stretch by a factor of k
g(x) = f(x -h) +k . . . . translation (right, up) by (h, k)
__
So, the translation down 2 units will make the function be ...
f(x) = x^2 ⇒ f1(x) = f(x) -2 = x^2 -2
The vertical stretch by a factor of 3 will make the function be ...
f1(x) = x^2 -2 ⇒ 3·f1(x) = f2(x) = 3(x^2 -2)
The horizontal translation left 5 units will make the function be ...
f2(x) = 3(x^2 -2) ⇒ f2(x +5) = f3(x) = 3((x +5)^2 -2)
The transformed function equation can be written ...
y = 3((x +5)^2 -2) = 3(x^2 +10x +25 -2)
y = 3x^2 +30x +69
__
The attachment shows the original function and the various transformations. Note that the final function is translated down 6 units from the original. That is because the down translation came <em>before</em> the vertical scaling.
I believe the answer should be DB = 10.
To find the missing side, you have to cross multiple the values on each side, and each value should be equal to each other.
Answer:
50 units
Step-by-step explanation:
Use long subtraction to evaluate.
Answer:
<h3>-8 divided by (-4)</h3>
Step-by-step explanation:
-18 divided by -9 is <u>+2</u> and that is what you want.
-18 divided by 2 is -9, not correct.
-12 divided by (-3) is +4, not correct.
-10 divided by 5 is -2, not correct.
Leaving the <em>correct</em> answer: -8 divided by (-4) is <u>+2</u>.
Remember: a negative times a negative equals a positive.
