A poll reported that 66 percent of adults were satisfied woth the job the major airlines were doing. Suppose 25 adults are selec
777dan777 [17]

Answer:

A)Option D

B)P(X = 15) = 0.1325

Step-by-step explanation:

A) From the question, the information given follows binomial distribution because there are two mutually exclusive outcomes for each​ trial, there is a fixed number of trials. The outcome of one trial does not affect the outcome of ​another, and the probability of success is the same for each trial.

So option D is correct.

B) From the question, we are told that the poll reported that 66 percent of adults were satisfied with the job. Thus, probability is; p = 0.66

Let X be the number of adults satisfied with the job. Since 25 are selected,

Thus;

P(X = 15) = C(25, 15) * (0.66)^(15) * (1 - 0.66)^(25 - 15)

P(X = 15) = 3268760 × 0.00196407937 × 0.00002064378

P(X = 15) = 0.1325

(25 points) A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The stan
zimovet [89]

Answer:

C = 0.65M+19.65

Step-by-step explanation:

Given the the standard charge S (in dollars) given by the function

S = 0.40M + 15.75, where M is the number of miles driven.

Also the insurance charge I (in dollars) is given by the function

I = 0.25M + 3.90

If C is the total charge (in dollars) for a rental that includes insurance, then:

C = S + I

Substitute the given function into the expression:

C = 0.40M + 15.75 + 0.25M + 3.90

Collect like terms

C = 0.40M+0.25M+15.75+3.90

C = 0.65M+19.65

<em>Hence an equation relating C to M is expressed as C = 0.65M+19.65</em>
