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.
There no other figure but can take a property that is linear pair or linear pair axiom
The number of advance tickets sold is 25 and same day tickets sold is 30.
Data Given;
- Advance Ticket = $30
- Same-day Ticket = $25
- Total Ticket = $60
- Total Cost of Ticket = $1625
<h3>System of Equations</h3>
Let the number of advance ticket be represented by x
Let the number of same-day ticket be represented by y
From the system of equations above, we can easily pick any to start our calculation.
Using equation (i),
x + y = 60
x = 60 - y ...equation(iii)
Put equation (iii) into equation (ii)
Put the value of y into equation (i)
From the calculation above, the number of advance tickets sold is 25 and same-day tickets is 30.

Answer:
Step-by-step explanation:
1. A right angle has a measure of 90°. The whole is the sum of the parts.
(2x +3)° +49° = 90°
2x +52 = 90 . . . . . . . . divide by °, collect terms
2x = 38 . . . . . . . . . . . . subtract 52
x = 19 . . . . . . . . divide by 2
__
2. A linear pair measures 180°. The whole is the sum of the parts.
(x -5)° +151° = 180°
x +146 = 180 . . . . . . . divide by °, collect terms
x = 34 . . . . . . . . .subtract 146
__
3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.
64° +(3x -1)° = 180°
3x +63 = 180 . . . . . . . divide by °, collect terms
3x = 117 . . . . . . . . subtract 63
x = 39 . . . . . divide by 3
