The equation for the motion of an object with constant acceleration is d = vt + at where dis distance traveled in ft, vis starting velocity in ft/s, a is
acceleration in ft/s2, and tis time in seconds. A racecar begins with a velocity of
200 ft/s and accelerates at 100 ft/s2. Write an expression for the distance the
car travels after t seconds. What is the GCF of the expression?

People end up tossing 12% of what they buy at the grocery store. assume this is the true population proportion and that you plan to take a sample survey of 540 grocery shoppers to further investigate their behavior. a. calculate the mean and the standard error for the sample proportion p. b. describe the sampling distribution of p in part a. draw a graph of this probability distribution with its mean and standard deviation. what is the probability that your survey will provide a sample proportion more than 15%? c. d. population proportion? what is the probability that your survey will provide a sample proportion within + 0.03 of the
