11. Suppose you buy 1 ticket for $1 out of a lottery of 1,000 tickets where the prize for the one winning ticket is to be $500.

erastovalidia [21]

Answer:

-50 cents

Step-by-step explanation:

The "Winnings" random variable has values -1 and 499

The associated probabilities are P(-1)= 999/1000; P(499)=1/1000

-----------------------------

Expected Value = -1(999/1000) + 499(1/1000) = -500/1000 = -50 cents

if michaels score is 87, the class average is 82, and the standard deviation is 4. what is michaels z-score?

AlexFokin [52]

Answer:

Z = 1.25

Step-by-step explanation:

$\displaystyle Z=\frac{\text{Observed Value}-\text{Mean of the Sample}}{\text{Standard Deviation of the Sample}}\\\\Z=\frac{x-\mu}{\sigma}\\ \\Z=\frac{87-82}{4}\\ \\Z=\frac{5}{4}\\ \\Z=1.25$

Hence, Michael's z-score is 1.25, which means that he scored 1.25 standard deviations above the class average.

Jordan's family traveled 3/8 of the distance to his grandfather's house on Saturday. They traveled 3/5 of the remaining distance

jarptica [38.1K]

Answer:

1/40

Step-by-step explanation:

You have to find the amount of distance they traveled since the start of the journey. 3/5 + 3/8 is 39/40. How did we get that, you may ask?

We need to find a number that both 5 and 8 have to make. That can be 40. But how we made 5 and 8 40, we need to do the same to the top numbers. So 39/40 when we add them up. Finally, we need to substract that from the whole, and this gets you 1/40. Hope this helps.

Have a wonderful day, my friend.
