A large pizza chain tracks how many pizzas each customer buys per order. The number of pizzas customers buy in any given order has a mean of 2.52.52, point, 5 pizzas and a standard deviation of 1.51.51, point, 5 pizzas. Suppose that we take random samples of 777 orders from this population and calculate \bar{x}
x
ˉ
x, with, \bar, on top as the sample mean number of pizzas purchased per order. We can assume that the orders in each sample are independent.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

If chord ab is congruent to chord cd, then what must be true about ef and eg?

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
