Answer:w40
Step-by-step explanation:
w15/w5 = w10
(w10)^4 = w40
I think that the D. CONE is the three-dimensional figure that will be formed when an equilateral triangle is rotated around the x-axis of the coordinate plane.

Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is
Answer:

Step-by-step explanation:
Albert: 60% of 30= 18
Anthony: 40% of 30= 12
18 - 12= 6
We can solve this using substitution.
because x-y=2.5
x=y+2.5
Now substitute x into other equation.
2(y+2.5)^2-2y=125
2y^2+10y+12.5-2y=125
2y^2+8y-112.5=0
Now comes the ugly part
y=-4+-sqrt(16+900)
y=-4+-sqrt916
y=-4+-2sqrt229
x=-1.5+-2sqrt229
