Answer:
2 is the correct answer.
Step-by-step explanation:
Given that Sue downloads music videos on her phone. The cost of the video downloads (in dollars) is given by the equation
, where c is the total cost of the videos and v is the number of videos.
Constant of proportionality is 2 here since whenever v increases by 1, cost increases by 2.

Answer:
By the Central Limit Theorem, the average value for all of the sample means is 14.
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sample means of size n can be approximated to a normal distribution with mean
and standard deviation, which is also called standard error
If the population mean is μ = 14, then what is the average value for all of the sample means?
By the Central Limit Theorem, the average value for all of the sample means is 14.
Answer:
The domain restriction for (f/g)(x) is x=7
Step-by-step explanation:
we have
so
Remember that
the denominator can not be equal to zero
so
Find the domain restriction
x-7=0
x=7
therefore
The domain is all real numbers except the number 7
(-∞,7)∪(7,∞)
