Answer:
2.05
Step-by-step explanation:
<span>A) The data form an almost linear correlation making their most likeable correlation coefficient 0.99. Thus the greater the time elapsed the greater the distance traveled, example of positive correlation.
B) Value of slope for the given time interval is deltaY/deltaX = (12-4)/(30-10) = 8/20 = 0.4. The slope represents the velocity with which the toy car moves, i.e. 0.4miles/min.</span>
Answer: 266
Step-by-step explanation: This is a ratio problem. If there are 14 chocolates with nuts out of every 32 chocolates, you can use this as a ratio and set it up as a proportion.
(1) 14 chocolates w/ nuts / 32 chocolates = n chocolates / 608 chocolates
(2) Solve for n: 8,512 = 32n; n = 266
10.99x = 3.99x + 280
7x = 280
x = 40
