i think the answer is no i used tge desmo graphing calculator and tht point wasnt on it
Answer:
$10.46
Step-by-step explanation:
Amount that can be won by Alexis ( xi ) = $0, $8 , $12
probability ( pi )
P( $0 ) = 13 / 52 = 1 / 4
P( $8 ) = 15 / 39 ( given that she wins this when an even number is drawn from three remaining decks )
P ( $12 ) = 1 - 15/39 = 24 / 39
<u>a) Alexis expected winnings per game </u>
= ∑ xi * pi = ( 0 * 1/4 ) + ( 8 * 15/39 ) + ( 12 * 24 / 39 )
= $0 + ( 120 / 39 ) + ( 288 / 39 ) = $10.46
Answer: -2
Step-by-step explanation:
since there are no multiplication you can simply go from left to right doing simple math. You start from a +4 that would be a positive 4, you subtract -3 so you get +1 then you subtract -4 and the result is -3 (negative 3) so now you are currently working with numbers lower than 0, adding +2 will make it -1 and finally you subtract for -1 and that will make it -2. Hope it's what u needed
If you know the derivative 
of some function 
, you can tell exactly who is, up to an additive, constant term. In fact, knowing , you have
In your case, we have
So, the integral is almost immediate:
So, up to some constant additive term, our function is 
To fix this constant, we know that the function passes through the point (6,10), so we have
And so our function is 
If we want to know when this function equals 6, we simply have to ask 
and solve for x, so we have
