Given the following segment of code,
// postcondition: returns x + y public int add(int x, int y) {}
// postcondition: return x * y public int multiply(int x, int y) {}
which of the following corresponds to this expression?
multiply(add(multiply(a, b), add(multiply(a, c), multiply(b, 2)
1.a * b + a * c + b * c * 2
2.a * b + a * c + b * c + 2
3.a * b + (a * c + b * c)
4.(a * b + a * c + b * c) * 2
5.2 * a * b + (a * c + b * c)

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
