Multiply each payout by the corresponding probability and take the total:
E[X] = 0×0.5 + 5×0.2 + 8×0.15 + 10×0.1 + 15×0.05 = 3.95
Answer:
Following are the responses to the given question:
Step-by-step explanation:
When x is squared, it's going to be bigger by the conclusion because the larger the faster. 
consistently exceeds 
, regardless of the price of X.
5x+3 is always 3 more so than 5x.
In particular, this can be classified according to its pathways 
So can alternatively just say "eventually," which means because when x really is big, you need to find one another's values. Then just select x=100, then plug it into every single other. To confirm this order:
So, the ascending order must be the right order!
Answer:
8x-40
Step-by-step explanation:
$40
40*90/100 = 36
You just have to be careful with the rest of the problem
One way in which to do this problem would involve subtracting 5 from 7 (result: 2) and then subtracting 3/5 from 8/9.
To subtract 3/5 from 8/9, you'd need to find the lowest common denominator (LCD) of 3/5 and 8/9, convert both fractions to have this LCD, and then subtract.
The LCD is (5)(9)=45. Then 8/9 and 3/5 become 40/45 and 27/45.
Subtracting 27/45 from 40/45 results in the fraction 13/45.
Then the full solution is 2 13/45.
You could also do this problem by converting 7 8/9 and 5 3/5 into improper fractions:
71/9 - 28/5. Again, the LCD is 45. Can you rewrite both fractions with 45 as the common denominator and then perform the subtraction?
