The number of bags of chips sold in a month is tracked and follows a normal distribution. After 2 years the mean is found to be 2.4 million, with a standard deviation of 0.3 million. What is the chance (percentage) that between 1.8 and 2.1 million bags are sold on a random month? (3 points: 1 for shown work, 1 for correct drawing, 1 for correct answer)

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
