The answer is 21 cubic units.

Just add them all!
The bottom = 10 cubes.
The middle = 6 cubes
The top = 5 cubes.
10 + 6 + 5 = 21 cubic units.

I hope this helped!

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation R=pL/(pi)d^2 where p represents the resi

SashulF [63]

Answer:

The resistance approaches infinity

Step-by-step explanation:

We are given

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation

$R=\frac{\rho L}{\pi (d)^2}$

where

p represents the resistivity of the wire’s material

L represents the length of the wire

d represents the diameter of the wire

now,

d approaches to 0

so, we can plug d=0 and find R

$R=\frac{\rho L}{\pi (0)^2}$

$R=\frac{\rho L}{0}$

$R=\infty$

So,

The resistance approaches infinity

koban [17]

Answer:

The p-value is;

d. 0.00131

Step-by-step explanation:

The given question parameters are;

Company A ${}$ Company B

Sample size 80 ${}$ 60

Sample mean ${}$ $\overline x_1$ $16.75 $\overline x_2$ $16.25

Population standard deviation ${}$ σ₁ $1.00 σ₂ $0.95

$z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu _{2} )}{\sqrt{\dfrac{\sigma_{1}^{2} }{n_{1}}+\dfrac{\sigma _{2}^{2}}{n_{2}}}}$

Therefor, we have;

$z=\dfrac{(16.75-16.25)-(0-0)}{\sqrt{\dfrac{1^{2} }{80}+\dfrac{0.95^{2}}{60}}} \approx 3.0128$

The p-value = 1 - 0.99869 (the area to the right of 3.01) = 0.00131
