A student survey was conducted in a major university, where data were collected from a random sample of 750 undergraduate students. One variable that was recorded for each student was the student's answer to the question: What is your favorite type of movie? Action/Comedy/Drama/Family/Horror/M usical/Science Fiction. These data would be best displayed using which of the following?a. histogramb. IQRc. boxplotd. stemplote. pie chart

e. Pie Chart

Step-by-step explanation:

In a student survey, students are asked about their favorite movie and so, the favorite movies can be divided into different categories but can't be meaningfully represented in numerical form. Thus, the favorite movie is a qualitative variable. For the qualitative type of variable pie chart is most suitable chart.

Histogram, IQR, box plot and steam plot are created for quantitative type of data.

Thus, the data would be best displayed by using Pie chart.

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
