A system of inequalities, where x is the rate of a spaceship in a video game and y is where the ship travels on the screen in 3.5 seconds, is represented by the graph. On a coordinate plane, 2 solid straight lines are shown. The first line is vertical at x = negative 2. Everything to the right of the line is shaded. The second line has a positive slope and goes through (negative 2, negative 6) and (0, 0). Everything to the left of the line is shaded.

Which symbol could be written in both circles in order to represent this system algebraically?

y Circle 3x

x Circle –2

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
