Answer:
(d.) Those who score high on one variable tend to score low on the other.
Step-by-step explanation:
A negative value of correlation coefficient (r) shows a relationship between two variables such that as one variable increases, the other decreases. It shows the inverse relationship between two variables with the dependence determined by the value of the correlation coefficient (r).
It can be observed that for graphs with negative slope, the correlation coefficient (r) is similarly negative. This speaks about its relationship too.
The correlation coefficient being negative doesn't mean the relationship between the two variables in question is bad, it just means that the correlation relationship is inverse (still dependent). A perfectly negative correlation is -1.
Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
Answer:
A. Kayla
Step-by-step explanation:
To find the difference between the two numbers we will do:
7°C - (-5°C)
Subtracting a negative number is the same as simply adding, so we can rewrite the equation as:
7°C + 5°C = 12°C
Answer:
Step-by-step explanation:
10x^2(3x^2 - 5x) Remove the brackets (Distributive Property)
10*3*x^2 * x^2 - 5x * 10x^2
30 x^(2 + 2) - 5*10x^(2+1)
30x^4 - 50x^3
I think the answer is D I'm not sure though
