Tbh I think the answer is 20 for nyCan company charges an initial rate of 5
So, there are multiple forms of this. First there's improper fraction form which would be
There's also decimal form
(the .6 is repeating).
Hope this helps!
Answer:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with the normal standard distribution table:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability

And we can find this probability using the complement rule and with the normal standard distribution table:
Answer:
8
Step-by-step explanation:
I got 7.5 because 3•5=15 and then you can divid 15 by 2 since it is a triangle
