Option B is correct.
Total time that Antony's family spent driving to and from the lake = 8.5 hr
Step-by-step explanation:
Using time formula:
As per the given statement: Anton's family drove 216 mi to the lake averaging 48 mi/hr .On the return trip home they averaged 54 mi/hr
⇒ Anton's family drove total distance = 216 mi
Speed of Antony's family driving to lake = 48 mi/hr
Time taken to driving to lake =
Now,
Speed of Antony's family driving from lake = 54 mi/hr
Time taken to driving from lake =
Total time spent driving to and from the lake = 4 + 4.5 = 8.5 hr.
therefore, the total time that Antony's family spent driving to and from the lake was, 8.5 hr
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
The sample mean is
The sample size is n = 6 packs
The standard error of the mean is mathematically represented as
substituting values
Given that the can’s contents follow a Normal distribution then then the probability that the mean contents of a six-pack are less than 12 oz is mathematically represented as
Generally
So
substituting values
From the normal distribution table the value of is
=>
