Answer:

Check the explanation

Step-by-step explanation:

1) probability for odd or 00 = (18+1)/38 = 0.5

2) expected value can be calculated as follows :

14 * win probability - 13 * lose probability

=14 * (18/38) - 13*(20/38)

= -0.21

Answer:

-0.21

Step-by-step explanation:

Firstly the probability for odd or 00 = (18+1)/38 = 0.5

Therefore we can calculate our expected value as follows :

14 * win probability - 13 * lose probability

=14 * (18/38) - 13*(20/38)

Hence our Answer is = -0.21

What is the reciprocals of the fraction 37/74
lidiya [134]
<h2>The reciprocals of the fraction \dfrac{37}{74} =  \dfrac{74}{37} or 2.</h2>

Step-by-step explanation:

We have,

\dfrac{37}{74}

To find, the reciprocals of the fraction \dfrac{37}{74} = ?

∴ \dfrac{37}{74}

Dividing numerator and denominator by 37, we get

= \dfrac{1}{2}

= \dfrac{37}{74} or, \dfrac{1}{2}

We know that,

The reciprocals of the fraction \dfrac{x}{y} =\dfrac{y}{x}

The reciprocals of the fraction \dfrac{37}{74} = \dfrac{74}{37} or \dfrac{2}{1}

= \dfrac{74}{37} or 2

Thus, the reciprocals of the fraction \dfrac{37}{74} =  \dfrac{74}{37} or 2.

What are the zeros of the polynomial function f(x) = x3 - 10x2 + 24x? I just want to know the name of the process to find the ze
Oxana [17]

f(x) = x³- 10x² + 24x

f(x) = x ( x² + 10x + 24)

f(x) = x (x + 6)(x+4)

x=0


-----------------
x+6 = 0
x = 0-6
x= -6


-------------
x+4 = 0
x = 0-4
x= -4

zero's would be: 0, -6 and -4,
So it is your third choice down.
