Answer:
Positive
Step-by-step explanation:
As height is increasing, shoe size is also increasing (positive slope)
Negative correlation is when one variable increases and the other decreases (negative slope)
Answer:
a) a^6+6a^4b+15a^2b^2+20b^3+15(b^4/a^2)+6(b^5/a^4)+(b/a)^6
b) 20
c) a^6+6a^4+15a^2+20+15/a^2+6/a^4+1/a^6
Step-by-step explanation:
(a+b/a)^6=a^6+6a^5(b/a)+15a^4(b/a)^2+20a^3(b/a)^3+15a^2(b/a)^4+6a(b/a)^5+(b/a)^6
a^6+6a^4b+15a^2b^2+20b^3+15(b^4/a^2)+6(b^5/a^4)+(b/a)^6
b) the coefficient of b^3=20
c) if b=1, the expression is
a^6+6a^4+15a^2+20+15/a^2+6/a^4+1/a^6
I am pretty sure the answer is 10. Someone correct me if I'm wrong
Answer:
-8
Step-by-step explanation:
I believe it is -8
first you 2(-2) - 4
then you -4 -4= -8
Hope that was helpful.
360 /12 = 30
Each 5 minutes is 30 degrees
2*pi/12 = pi/6
each 5 minutes is pi/6 degrees
pi/3 = 2*pi/6 = 2 * pi/6 = 2* 5 minute = 10 minutes
the minute hand moves from 4 to 6
2 * pi/3 = 2 * (2*pi/6) = 4 *(pi/6) = 4 * 5 minutes = 20 minutes
The minute hand moves from 3 to 7
5 * pi/6 = 5 * 5 minutes = 25 minutes
the minute hand moves from 5 to 10
7 * pi/6 = 7 * 5 minutes = 35 minutes
the minute hand moves from 2 to 9
