Your answer is Y= -x\5+7\15
Answer:
-$173
Step-by-step explanation:
The expected value is the sum of products of payments and their respective probabilities.
He pays $243 with probability 1: (-$243)(1) = -$243
He receives $100,000 with probability 1 -0.9993: ($100,000)(0.0007) = $70
The expected value for the man is ...
-$243 +70 = -$173 . . . . a cost of $173

Answer:
- X = Y -9
- Y = Z +7
- X +Y = 25
Step-by-step explanation:
We can let X, Y, and Z represent the ages of Xavier, Yolanda, and Zed, respectively.
1) X = Y -9 . . . . . . Xavier is 9 years younger than Yolanda
2) Y = Z +7 . . . . . Yolanda is 7 years older than Zed
3) X +Y = 25 . . . . the sum of ages of Xavier and Yolanda is 25

<em>Additional comment</em>
The first equation can be substituted into the last to give 2Y-9=25 ⇒ Y=17. The other ages are easily computed once you know this. X=8, Z=10.
