<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>
3/10 divided by 4/5
You can solve this problem by changing the second fraction and multiplying. 3/10 times 5/4 is 15/40 = 3/8
(-2x)(x^2)+(-2x)(-3) = -2x^3 + 6x
Answer:
You need to use appropriate formula for the surface area. You may find formula in your mathematics book.
