Answer:
(a) 0.12924
(b) Taking into consideration significance level of 0.05 yet the value of p is greater than 0.05, it suggests that the coin is fair hence the coin can be used at the beginning of any sport event.
Explanation:
(a)
n=200 for fair coin getting head, p= 0.5
Expectation = np =200*0.5=100
Variance = np(1 - p) = 100(1-0.5)=100*0.5=50
Standard deviation,
Z value for 108,
P( x ≥108) = P( z >1.13)= 0.12924
(b)
Taking into consideration significance level of 0.05 yet the value of p is greater than 0.05, it suggests that the coin is fair hence the coin can be used at the beginning of any sport event.
Solution :
Given :
k = 0.5 per day


Volume, V 
Now, input rate = output rate + KCV ------------- (1)
Input rate 


The output rate 
= ( 40 + 0.5 ) x C x 1000

Decay rate = KCV
∴
= 1.16 C mg/s
Substituting all values in (1)

C = 4.93 mg/L
Answer:
Flow rate is 
Explanation:
Given information
Density of oil, 
kinematic viscosity, 
Diameter of pipe, D= 5 mm= 0.005 m
Length of pipe, L=40 m
Height of liquid, h= 3 m
Volume flow rate for horizontal pipe will be given by
where
is dynamic viscosity and
is pressure drop
At the bottom of the tank, pressure is given by

Since at the top pressure is zero, therefore change in pressure a difference between the pressure at the bottom and the top. It implies that change in pressure is still 
Dynamic viscosity, 
Now the volume flow rate will be

Proof of flow being laminar
The velocity of flow is given by

Reynolds number, 
Since the Reynolds number is less than 2300, the flow is laminar and the assumption is correct.
The answer will be : 0 volts.
