Answer:
Positive nonlinear association
Step-by-step explanation:
The correlation coefficient is fairly low at 0.28, so there is a positive association, but it is definitely not linear.
(It may not be fair to call it non-linear, either. There seems to be no specific value of correlation coefficient below which you declare there to be "no association.")
1. You have that:
-The <span>police car accelerates 60 meters per second.
- The minivan has a speed of 45 meters per second and is 600 meters ahead of the police car at the beginning of the chase.
2. Therefore, you have:
V1xt=V2xt-600
V1 is the speed of the minivan and V2 is the speed of the police car
3. The time is:
t=-600/V1-V2
t=-600/(45-60)
t=40 seconds</span>
Answer:
Both the mean and median will decrease, but the mean will decrease by more than the median.

Answer:
17
Step-by-step explanation:
Let x be the first side
x+2 is the next side ( consecutive odd number)
x+4 is the third side ( consecutive odd number)
P = x + x+2 + x+4
45 = x + x+2 + x+4
Combine like terms
45 = 3x+6
Subtract 6 from each side
45-6 = 3x+6-6
39 = 3x
Divide by 3
39/3 = 3x/3
13 =x
The longest side is
x+4
13+4 = 17
The longest side is 17
