Answer:
Step-by-step explanation:
3.6 x 10 = 36
36^4 equals 1,679,616
Unless you wrote the equation wrong in which case I would need to see the right equation ofc
Pablo ran farther, the work I did is below. I used an LCD (Lowest common denominator) to solve the problem.
Answer:
And we want this probability:
And using the normal standard distribution or excel we got:
And the best option would be:
D 0.0233
Step-by-step explanation:
For this case we have the following parameters:
And we select a sample size of n=13. And we want to find this probability:
We can assume that the distribution for this case is normal and then we can use the z score formula given by:
And if we replace the data given we got:
And we want this probability:
And using the normal standard distribution or excel we got:
And the best option would be:
D 0.0233
