3. Suppose the speeds of cars on a street are normally distributed, with a mean of 76.4 kph and a standard deviation of 5.0 kph. Part A: To the nearest tenth of a percent, what is the probability that a car is going slower than 70 kph? (3 points)

Part B: To the nearest tenth of a percent, what is the probability that a car is going faster than 80 kph? (4 points)

Find the roots of the equation below. x^2 - 6 + 9 = 0

Consider the graph of the exponential function y=3(2)×

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
