Someone please help me
Variable Y: 63 100 88 30 36 17 47 72 52
A. Negative linear association
B. Negative non linear association
C. Positive linear association
D. Positive non linear association
I think it could be B..not sure though. Please help!
Step-by-step explanation:
For a wave:
y = A sin (2π/T x − φ) + B
A is the amplitude,
T is the period,
φ is the phase shift,
and B is the offset.
The given wave is:
f(x) = -5 sin(x + 2π) − 4
So the amplitude is -5, the period is 2π, and the phase shift is -2π.
To find how much you save, you need to find out how much you pay for each tire. Your 2 equations are
2x=216 (x being the price of the tire, which you do not know)
x=108
4x=380
x=95
As you can see, the price of the tire from the manager's special is cheaper, but to find out by how much you subtract.
108-95=13
So you save $13 per tire.
Answer:
$13
Step-by-step explanation:
you have $216 for a pair, find how much for only one tire
216/2=108
then you need to find the unit rate for 4 tires
380/4=95
lastly, subtract to find how much more you save
108-95=13
therefore 13 is your answer
hope this helps
