There are no negative square roots
Mean=8.1 (add all numbers and divide by how many there r)
Median=9.25 (place all numbers in a chronological line and find the middle value)
Mode=9.2 (value that appears the most)
Range=10.5 (10.5-0)
Answer:
$365.70
Step-by-step explanation:
The formula to find this is 
For this, a is the initial amount, r is the growth rate percentage (but displayed as a decimal), and t is time.
So to solve, you would do
Answer: 4 miles in 1/3 hour
Step-by-step explanation:
Answer:
≥ 420 boards
Step-by-step explanation:
Write the required relation between cost per board and "x" (the number of boards that must be sold).
143 + 30240/x ≤ 215 . . . . . . . note that the first term is <em>not</em> 143x
Subtract 143
30240/x ≤ 72
Multiply by x/72. This is a positive number because x is a positive number.
30240/72 ≤ x
420 ≤ x
At least 420 surfboards must be sold to limit the final cost per board to $215.
