No, I do not agree with Jada.
Quad A has 3, 6, 6, 9
Quad B is a scale of A with shortest length being 2
A scale is basically a fraction or a ratio. The scale of Quad A to B is 3/2 since Quad A's shortest length is 3.
Using the scale factor of 3/2, we can determine the rest of Quad B's demensions through cross multiplication.
3/2 = 6/4
3/2 = 9/6
Quad B's demensions are 2, 4, 4, 6.
No because 5+3(1-x) it is 5+3-3x them 8-3x not 8-8x
Answer:
D. 33.49
Step-by-step explanation:
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
