Answer: She is correct because the average of the numbers 2, 3, 1, 4, 5, 2, 3, 4, 3, is 3.
Step-by-step explanation:
To find average you add all of the listed numbers, (2, 3, 1, 4, 5, 2, 3, 4, 3) which is 27. You then divide 27 by the amount of listed numbers, which is 9. 27 divided by 9 is 3. There for the average amount of strokes it takes to hit the ball into the hole of each green is 3.

The volume of a cone can be found by using the equation V=(1/3)(pi*r^2*H). Given the information that H= 6cm and V= 8pi cm^3, the expression is 8pi=(1/3)(pi*r^2*6). (The second picture.)
Answer:
I think the answer is odd. I am not sure because I don't know this topic really well.

Answer:
Step-by-step explanation:
If we call x the number of correct questions obtained in the 9 attempts, then:
x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.
So, the p of x successes has the following formula.
Where:
n = 9
p = 0.6
We are looking for P(x<4)
By definition:
Then:
Sarah's income = Number of trays × Rate per tray
y = 450 × 8
If there is an increase of 0.85 in price,
New price = 8 + 0.85
For x number of increases,
new price = 8 + 0.85x.
Number of trays reduced = 450 - 15x.
So, Sarah's income in this case is y = (450 - 15x) (8 + 0.85x).
