Ahorse-drawn carriage tour company has found that the number of people that take their tour depends on the price charged per customer. the more the company charges for a tour, the fewer people decide to take the tour.

the function c(x)=50+5x represents price charged per customer where x is the number of $5 increases they charge over a rate of $50 per person.

the function p(x)=100−2x represents the number of customers expected for the day, where x is the number of $5 increases they charge over a rate of $50 per person.

what does (p⋅c)(2) mean about the horse-drawn carriage tour company?

the horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $40.

the horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60. < took the test and this was the right answer.

the horse-drawn carriage tour company can expect to take in $3760 when the charge per customer is $60.

the horse-drawn carriage tour company can expect to take in $3760 when the charge per customer is $40.

Given f(x) = 2x^2- 5x+1, determine the function value f(2). do not f(x) = in your answer

Aparticular telephone number is used to receive both voice calls and fax messages. suppose that 25% of the incoming calls involve fax messages, and consider a sample of 25 incoming calls. (a) what is the expected number of calls among the 25 that involve a fax message?

Overproduction of uric acid in the body can be an indication of cell breakdown. this may be an advance indication of illness such as gout, leukemia, or lymphoma.† over a period of months, an adult male patient has taken nine blood tests for uric acid. the mean concentration was x = 5.35 mg/dl. the distribution of uric acid in healthy adult males can be assumed to be normal, with σ = 1.87 mg/dl. (a) find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. what is the margin of error? (round your answers to two decimal places.) lower limit upper limit margin of error (b) what conditions are necessary for your calculations? (select all that apply.) σ is unknown n is large σ is known normal distribution of uric acid uniform distribution of uric acid (c) interpret your results in the context of this problem. there is not enough information to make an interpretation. the probability that this interval contains the true average uric acid level for this patient is 0.05. the probability that this interval contains the true average uric acid level for this patient is 0.95. there is a 95% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. there is a 5% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. (d) find the sample size necessary for a 95% confidence level with maximal margin of error e = 1.10 for the mean concentration of uric acid in this patient's blood. (round your answer up to the nearest whole number.) blood tests
