Astudent is taking a multiple-choice exam in which each question has four choices. assume that the student has no knowledge of the correct answers to any of the questions. she has decided on a strategy in which she will place four balls (marked a, b,c, and d) into a box. she randomly selects one ball for each question and replaces the ball in the box. the marking on the ball will determine her answer to the question. there are five multiple-choice questions on the exam. what is the probability that she will geta. five quesions correct? b. at least four questions correct? c. no questions correct? d. no more than two questions correct?

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

2,160 π
