The college of arts and science at delta university has nine departments. the number of faculty in each department is shown below. what is the mean number of faculty in the college of arts and science? 8, 12, 9, 15, 17, 11, 13, 14, 7

11.78 would be the mean(aka avrage)

Ibelieve a is the correct answer because 3 is the y-intercept you can see it from the graph. so from here the answers could only be a and c. they are differently at the sign.substitute x with 1so the equation for a is 3*(1.4)^x3*(1.4)^1 = 4.2look back at the graph it is true that when x= 1 y= 4.2if you use equation from c. when x= 1 then y will be negative number which is falseso correct answer is a

This is the graph x=1
