Answer:
First degree
Step-by-step explanation:
The first-serve percentage of a
tennis player in a match is normally distributed with a standard deviation of
4.3%. If a sample of 15 random matches of
the player is taken, the mean
first-serve percentage is found to be 26.4%. The margin of error of the sample
mean is 83.71%.
Answer:
z^5
Step-by-step explanation:
z^8 * z^-3
Since we are multiplying exponents and the bases are the same, we can add the exponents
z^(8-3)
z^5
Answer:
See proof below
Step-by-step explanation:
We have to verify that if we substitute in the equation the equality is true.
Let's substitute first in the right hand side:
Now we use the distributive laws. Also, note that (this also works when the power is n-2).
then the sequence solves the recurrence relation.
