That easy just divide 9 by 22 if need simplify it
To find the expected value of your gain in each prize, subtract the price of the ticket from the prize:
If the prize is $500: $500 - $2 = $498
If the prize is $250: $250 - $2 = 248
If the prize is $160: $160 - $2 = $73
But if you did not win any cash prize, you do not have any gain because
0 cash prize - $2 ticket = -$2 which is a loss
Answer:
No
Step-by-step explanation:
We can not determine that the low test scores are caused by sleep deprivation. Because there are many factors that can affect on a student's test score such as:
- not carefully review all the lesson before the test
- the feeling of nervous in the exam room
- poor academic ability
- ....so on
So, getting less than 8 hours of sleep is just one of the independent variables determining the test score, it is not a strong correlation.
Slope of 1 is -2/5. intercept is 3
slope of 2 is 1/4. intercept is 3
