Suppose that a box contains 6 cameras and that 3 of them are defective. A sample of 2 cameras is selected at random (with replacement). Define the random variable X as the number of defective cameras in the sample. Note: For X to have a binomial probability distribution the sample must be with replacement, otherwise the trials are dependent. Write the probability distribution for X . k P( X = k ) 0 Correct .2 Incorrect 1 Correct .5 Correct 2 Correct .2 Incorrect What is the expected value of X ?

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.
