(2 + 6)^2 + 3 (sqrt (2 * 8))
8^2 + 3(sqrt 16) =
64 + 3(4) =
64 + 12 =
76
Answer:
subtract 265 from 305 and get 40 (305 - 265 = 40) then divide that by 8 and get 8 (40/8 = 5). so F=5 (each party favor is 5 dollars)
Step-by-step explanation:
Answer:
Where and
We select a sample size of n =8. Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
And the standard error would be:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
Let X the random variable that represent the compressive strength of concrete of a population, and for this case we know the distribution for X is given by:
Where and
We select a sample size of n =8. Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
And the standard error would be:
I Would Say The Answer Is C
Answer: 24 miles
Step-by-step explanation: 12 mph is two times as fast as 6 mph so 6 hours round trip is 2 hours for bike and 4 hours for jogging. You can either plug 2 for 12 (bike) or 4 for 6 (jog) either way you get 24
