Set each factor equal to zero and solve.
x + 6 = 0 x - 3 = 0
x = - 6 x = 3
13 + 23 · (19 - 7)
Do the parentheses first.
13 + 23 · (12)
Now do multiplication.
13 + 276 = 289
The answer is D) 289.
The mean is 35/5=7
The variance is the average of the sum of squared differences of each element from the mean:
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
