You could roll a 6-sided die 3 times to simulate this. This is a good simulation because it has one side for each possible tool, and each roll is independent, just as selecting the tool with replacement would be.
It is false or 8/9 is equal to 1
Answer:

Step-by-step explanation:
Given

Required
True values of x
We have:


Collect like terms


Divide both sides by 3


This means that x has a value lesser than 14.67.
Hence, the valid values are:

Answer:
61.2 mph
Step-by-step explanation:
Let's first calculate the individual legs of Adara's trip in terms of both time and distance:
<u>Ashdown to Bridgeton</u>
3 hr at 60 mph = 180 miles in 3 hours
<u>Bridgeton to Carton</u>
30 miles at 70 mph: 30 miles/(70 miles/hour) = 0.429 hours
<u>Total Trip</u>
Miles = 180 + 30 = 210 miles
Time = 3 + 0.429 = 3.429 hours
Average speed is (210 miles)/(3.429 hours) = 61.25 or 61.2 miles/hour to 1 decimal point.
