An electronic switch has a constant failure rate of 10-3 per hour. a) What is the expected life of the switch? b) What is the standard deviation of the switch? c) What is the probability that the switch will last between 1200 and 1400 hours?

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.

Determine domain and range, largest open interval, and intervals which function is continuous.

What expression is equivalent to (84+16)
