Answer:
He ate 40% of it
Step-by-step explanation:
20/50 is 2/5, which is basically 4/10 therefore equaling 40%
Since the standard deviation is not given, we assume the process is a Poisson process, with mean 12000 miles.
From Poisson distribution tables, we see that with a value of lambda(mean)=12000, the lower tail probability for x=12140 miles is 0.9000105, which means that the 90 percentile is 12140 miles.
The lower-tail probability of 9000 miles is 6.2*10^(-181) which is essentially zero.
NOTE: if the problem were modelled with a normal distribution, the probabilities would be completely different.
Answer:
The inequality is true.
Step-by-step explanation:
To show that it is true, you simply sub in 4 for x and 5 for y and see if the statement is true or not
7(4)-3(5) < 19
28-15 < 19
13 < 19
Answer:
first 3 are Yes on the top. number 4: because they are both coplanar. number 5: Yes. number 6 is no. number 7: Yes. number 8 is plan.
