Answer:
The median would be 10. The number in between 9 and 11 would be 10
Step-by-step explanation:
The numbers in order would be 5,5,7,9,11,14,16,18. Since there is an even amount of numbers in the sequence, the middle two numbers are 9 and 11. You add them together to get 20 then divide by 2. So the answer would be 10.
Hope this helped!!!
The third choice is appropriate.
an = 5 - 3(n - 1); all integers n ≥ 1
_____
This equation follows the form for the general term of an arithmetic sequence.
an = a1 + d(n - 1)
where a1 is the first term (corresponding to n=1), and d is the common difference. From the problem statement, a1 = 5 and d = 2 - 5 = -3.
Answer:
y=3.75
x=9.6
Step-by-step explanation:
The arithmetic operation (f − g)x which can be used to determine the difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours is (f − g)x = - 5x + 25
<h3>Function</h3>
Camp counselor:
- Hourly rate = $10 per hour
- Bonus = $50
Earnings function
f(x) = 10x + 50
Lifeguard:
- Hourly rate = $15 per hour
- Bonus = $25
Earnings function
g(x) = 15x + 25
So,
(f − g)x = f(x) - g(x)
= (10x + 50) - (15x + 25)
= 10x + 50 - 15x - 25
(f − g)x = - 5x + 25
Therefore the function (f − g)x is (f − g)x = - 5x + 25
