Answer:
161.9179
Step-by-step explanation:
π = 3.142 (Constant value)
d = Diameter
If radius and diameter is unknown, then
Formula: c = 2√(πa)
Good luck
-5+-12 is -17
For lack of a better metaphor, it's like digging a pit deeper than it already is.
We will use binomial
distribution in this problem.
<span>The solution would be like
this for this specific problem:
</span><span>P(default) = p = 4% = 0.04 </span><span>
<span>q = 1-p = 1-0.04 = 0.96 </span>
n = 5</span>
<span>P(r) = nCr*q^(n-r)*p^r </span>
<span>Required probability =
P(r=2) = 5C2*0.96^3*0.04^2 </span>
= 0.0142 OR 1.42%
<span>The probability that at most
two customers in the sample will default on their payments is 1.42%.</span>
Answer:
Re= 5*10^5
Step-by-step explanation:
The numbers are not totally clear as they repeat each other. Under this consideration I will assume the closest values according to the advertised.
r=0.5m
V=1m/s (or) V=11m/s
![\rho = 1000kg/m^3 \\\upsilon = 0.001N/m^2s](https://tex.z-dn.net/?f=%5Crho%20%3D%201000kg%2Fm%5E3%20%5C%5C%5Cupsilon%20%3D%200.001N%2Fm%5E2s)
We know that Reynolds number is given by,
![Re=\frac{\rho \upsilon r}{\upsilon}\\Re= \frac{1000*1*0.5}{0.001}\\Re= 5*10^5](https://tex.z-dn.net/?f=Re%3D%5Cfrac%7B%5Crho%20%5Cupsilon%20r%7D%7B%5Cupsilon%7D%5C%5CRe%3D%20%5Cfrac%7B1000%2A1%2A0.5%7D%7B0.001%7D%5C%5CRe%3D%205%2A10%5E5)
Or for the another velocity
![Re=\frac{1000*11*0.5}{0.001}\\Re= 5.5*10^{6}](https://tex.z-dn.net/?f=Re%3D%5Cfrac%7B1000%2A11%2A0.5%7D%7B0.001%7D%5C%5CRe%3D%205.5%2A10%5E%7B6%7D)
5*15.75=78.75
128-2=126
126-78.75=47.25
47.25/7=6.75
The length of each piece of the seven pieces would be 6.75 inches.
