Answer:
($3.90)(12) - (2)($3.90) = 39.00
39.00/12 = 3.25 per pretzel

Answer:
The induced emf is 
Step-by-step explanation:
Now assume that the coil is shaped as a rectangle with length
and width b
This implies that the area of the coil is 
Now when it enter into the uniform magnetic field the magnetic flux due to its movement as stated in the question is mathematically represented as

=> 
Now the induced emf is mathematically represented as

=> ![\epsilon = B * l [\frac{db}{dt} ]](https://tex.z-dn.net/?f=%5Cepsilon%20%20%20%3D%20%20B%20%2A%20%20l%20%20%5B%5Cfrac%7Bdb%7D%7Bdt%7D%20%5D)
The
is constant because as it glides to and from the magnetic field it is displaced along the horizontal plane while along the vertical plane it is constant
Here 
Where is the velocity the glide (i.e the coil)
So

Answer:
Step-by-step explanation:
Given 
a)
we know that 
therefore 
on integrating we get
c=(1/6640)
b)
on doing the integration we get
=0.37349
c)
marginal density of X is
on doing integration we get
f(x)=(4x+3)/3320 ; 0<x<40
marginal density of Y is
on doing integration we get
d)
solve the above integration we get the answer
e)
solve the above integration we get the answer
f)
Two variables are said to be independent if there jointprobability density function is equal to the product of theirmarginal density functions.
we know f(x,y)
In the (c) bit we got f(x) and f(y)
f(x,y)cramster-equation-2006112927536330036287f(x).f(y)
therefore X and Y are not independent
