Keep Flip Change
Keep the first fraction
3/4
Flip the second fraction(reciprocal)
6/1 -> 1/6
Change the sign
÷ -> ×
So
3/4 × 1/6
The mean of a set of numbers is the average. In this problem, add all of the numbers together ( negative numbers for the losses) and then divide by the amount of games total.
Here are the numbers we have to use:
+7
-3
-2
+4
+9
the problem would be 7-3-2+4+9=15
Now divide 15 by your total amount of games which would be 5.
15/5=3
The average difference would be 3. Now a rule in math is to answer a word problem with a sentence.
The mean difference in scores over the five games played would be 3.
Hope this helps!

Answer:
(1) 56 miles/hour
Step-by-step explanation:
We need to find the average rate of change from t = 2 to t = 9.
At t = 2 hours, d = 106 miles.
At t = 9 hours, d = 498 miles.
The average rate of change in function f(x) from x = a to x = b is
[f(b) - f(a)]/(b - a)
average rate of change from t = 2 to t = 9 =
(498 - 106)/(9 - 2) = 392/7 = 56
Answer: (1) 56 miles/hour
