COMPLETE EVERY PART AND YOU WILL BE NAMED BRAINLIEST! THANK YOU! Katalina is planning to attend a local community college as a full-time student before transferring to a four-year university. The cost of her tuition (excluding other fees and expenses) can be determined using the equation f(x) = 215x, where x is the number of credit hours she registers for. Part One
In this situation, is y a function of x? Explain in terms of the situation.

Part Two
Describe the relationship between the cost of Katalina’s tuition and the number of credit hours she registers for.

Part Three
In order to be considered a full-time student, Katalina must register for at least 12 credit hours but no more than 21 credit hours.
Explain how Katalina can determine the cost of registering as a full-time student.

Part Four
Compare and contrast the process Katalina would use for determining each of the following:
** the number of credit hours she registered for if she receives a bill for $3,870.
** the cost of her tuition if she registered for 18 credit hours.

Max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

The resumâ´es of two male applicants for a college teaching position in chemistry are placed in the same file as the resumâ´es of two female applicants. two positions become available, and the first, at the rank of assistant professor, is filled by selecting one of the four applicants at random. the second position, at the rank of instructor, is then filled by selecting at random one of the remaining three applicants. using the notation m2f1, for example, to denote the simple event that the first position is filled by the second male applicant and the second position is then filled by the first female applicant, (a) list the elements of a sample space s; (b) list the elements of s corresponding to event a that the position of assistant professor is filled by a male applicant; (c) list the elements of s corresponding to event b that exactly one of the two positions is filled by a male applicant; (d) list the elements of s corresponding to event c that neither position is filled by a male applicant; (e) list the elements of s corresponding to the event a â© b; (f) list the elements of s corresponding to the event a âş c; (g) construct a venn diagram to illustrate the intersections and unions of the events a, b, and c.

How many and of which kind of roots does the equation f(x)=2x^4−9x^3+17x^2−16x+6 have?
