A. write a function that takes an array of ints, and the size of the array – another int. it also returns a double. call this one ‘average.’ return a double that is the average of the values in the array. demonstrate that it works by finding the average of an array with these values {78, 90, 56, 99, 88, 68, 92}.

i guess the correct option is letter a.

use contrasting font sizes, but the same font style

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
