Answer: 554
Step-by-step explanation:
Formula we use to find the sample size :
Given : Standard deviation :
Margin of error : E=one quarter hour = 0.25 hour
Two-tailed , Critical value use for 0.95 degree of confidence:
i.e.
Hence, the required sample size = 554
i.e. 554 executives should be surveyed.
Answer:
Step-by-step explanation:
Well first we have to use the formula where for pi we will be repacking it with 3.14.
So the radius is 4 inches and the height is 9 inches.
So we have to plug them in .
So using PEMDAS we have to so first.
So is 16 and now we have to multiply it by 9 and 3.14 and we get 452.16in^3.
1) x=-5
2) x=-31\-6
3) x=-13
4) x=-2
5) x=-16
3 of calebs pics are giraffes
18 / 6 = 3
This is the concept of calculus:
dV/dt*dh/dV=dh/dt
Volume of the cone is given by:
V=(1/3)πr^2h=1/3*π*3^2*h=3π
dV/dh=3*π=3π
dh/dV=1/(3π)
dV/dt=100 m^2/sec
thus;
dh/dt=1/(3π)*100
=33 1/3 m/s
