Answer:
a. C. The experiment consists of n identical, independent trials, where there are only two possible outcomes, S (for Success) and F (for Failure). The probability of S remains the same from trial to trial. The variable x is the number of S's in n trials.
b. A. For any young adult, the probability that they own a mobile phone with internet access is p.
c. A. In a random sample of 500 young adults Upper E left parenthesis x right parenthesis E(x) will always be the number of young people surveyed that will own mobile phones with internet access.
Explanation:
A binomial random variable is mostly used to show the number of successful results in a repeated number of binomial experiments. Thus, we can infer that the variable 'x' has the properties of a binomial random variable. The expected value of the variable 'x' is equivalent to the probability-weighted mean of all possible values of x.

Answer:
$26,000
Explanation:
To calculate the total depletion expense for a year, we must first calculate the depletion expense for every ton of ore extracted:
depletion expense per ton = cost of the mine / total tons extracted
depletion expense per ton = $1,600,000 / $400,000 = $4 per ton extracted
If during the first year Weber Company extracted 6,500 tons, their depletion expense for the year = 6,500 tons x $4 per ton = $26,000
