Answer:
900.000 000 + 5050.000 000 + 9.000 + 600 + 20 + 7
=900+5050+9+600+20+7=6586 is standard one
Answer:
She should be expected to have 2.11 aces.
Step-by-step explanation:
I suppose there was a small typing mistake. It should be: On average she gets an ace of 8.44% of her serves.
Then
For each serve, there are only two possible outcomes. Either there is an ace, or there is not. The probability of there being an ace in a serve is independent of other serves. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

She gets an ace of 8.44% of her serves.
This means that 
She attemps 25 serves:
This means that 
How many aces would you expect her to have

She should be expected to have 2.11 aces.
Answer: 171 cm
Step-by-step explanation: im not sure if this is right but
9x12=108
9x7=63
108+63=171
Withdrawals are when cash is taken out from the account
Flora withdraws an amount of $75 at a time from her bank account
she makes 7 such withdrawals
one withdrawal she takes out - $75
then seven withdrawals leads to - $75 x 7 = $525
then overall change in her account has been a net withdrawal of $525
so the overall change in the account is -$525
Set the denominatior equal to zero to find vertical asymptotes. Horizontal take the highest degree of the top and divide it by the highest degree of the bottom.

Vertical: x=3, x=-3
Horizontal : y=1
