Answer:
mean age of women
(x+y+z)/3=27
mean age of men
(x1+x2+x3+x4+x5+x6)/6=34
mean age of all people in the office
x+y+z=27*3=81
x1+...x6=34*6=204
so
mean age( x+y+z+x1+x2+..x6)/(3+6)=(27*3+34*6)/9
=(81+204)/9=285/9=32 approximately

Step-by-step explanation:
You can type it into desmos graphing calculator- hope this helps
Original investment is V
In the first year V decreased by 0.08V to give V - 0.08V
In the second year; V - 0.08V increased by $450 to give V - 0.08V + $450
The value (n) after two years = V - 0.08V + $450
The correct choice is 'D.'
Answer:
64z^2
Step-by-step explanation:
Here's why, it's actually very simple we use exponent rule when raising something to a power. In this case we're raising the term to the second power. So we raise both -8, and z. As so: (-8)^2 x (z)^2
Which equals 64z^2.
