Answer:


Step-by-step explanation:




Suppose I have a bag of n biased coins, and I sample without replacement m<n of them, and measure each coin i for their parameter pi∈[0,1], that is each coin is Bernoulli(pi). Now I would like to ask what is the most likely pm+1 on the next coin I pick. I am not sure how to answer this question aside from taking the mean of all m coins' parameter so far. That is: p^m+1=p1+…+pmm.

The function f(x) = 1/2 x + 3/2 is used to complete this table.
Mrac [35]

Answer:

a) f(-1/2)  = -2 is NOT TRUE.

b)  f(0)  =3/2 is  TRUE.

c)   f(1)  = -1 is NOT TRUE.

d)   f(2)  = 1 is NOT TRUE.

e)   f(4)  = 7/2  is  TRUE.

Step-by-step explanation:

Here, the given function is  f(x) = (\frac{1}{2}) x+\frac{3}{2}

Now, checking for each values for the given function:

a) Putting x  = (-1/2):

 f(\frac{-1}{2} ) = (\frac{1}{2})(\frac{-1}{2} ) +\frac{3}{2}   = \frac{-1}{4}  + (\frac{3}{2} )\\\implies f(x) = \frac{-1 + 6}{4}  = (\frac{5}{4} )

and (5/4) ≠  -2

Hence, f(-1/2)  = -2 is NOT TRUE.

b)Putting x  = 0 :

f(0) = (\frac{1}{2})(0 ) +\frac{3}{2} = (\frac{3}{2} )

Hence, f(0)  =3/2 is  TRUE.

c) Putting x  = 1:

f(1 ) = (\frac{1}{2})(1 ) +\frac{3}{2}   = \frac{1}{2}  + (\frac{3}{2} )\\\implies f(x) = \frac{3 + 1}{2}  = (\frac{4}{2} )   = 2\implies 2   \neq -1

Hence, f(1)  = -1 is NOT TRUE.

d)Putting x  = 2:  

f(2 ) = (\frac{1}{2})(2 ) +\frac{3}{2}   = 1+ (\frac{3}{2} )\\\implies f(x) = \frac{2 + 3}{2}  = (\frac{5}{2} )

and (5/2) ≠  1

Hence, f(2)  = 1 is NOT TRUE.

e)Putting x  = 4:

 f(4 ) = (\frac{1}{2})(4 ) +\frac{3}{2}   = 2  + (\frac{3}{2} )\\\implies f(x) = \frac{4 + 3}{2}  = (\frac{7}{2} )

Hence, f(4)  = 7/2  is  TRUE.

Tems11 [23]
You have $284 in your credit card balance. 186-174= 12. 99+35= 134 and then 12-134= -122. So 406-122= 284.

Find the cube roots of 27(cos 330Á + i sin 330Á). Please help c:
Mashcka [7]
Use formula
e^{ix}=\cos{x}+\sin{x}

\sqrt[3]{27(\cos{330^o}+i\sin{330^o})} &#10;\\\sqrt[3]{27e^{i330^o} }&#10;\\  \sqrt[3]{27}  \sqrt[3]{e^{i330^o}} &#10;\\ \sqrt[3]{3^3} \sqrt[3]{e^{i110^o\times 3}} &#10;\\ \sqrt[3]{3^3} \sqrt[3]{(e^{i110^o})^ 3}} &#10;\\ 3e^{i110^o}&#10;\\3(\cos{110^o}+i\sin{110^o})

Since 330^o=360^o+330^o=690^o&#10; and 330^o=2\times 360^o+330^o=1050^o there are two more solutions:
1. 3(\cos{230^o}+i\sin{230^o})
2. 3(\cos{350^o}+i\sin{350^o})
