Eitan randomly selected volcanoes to travel to and study. After traveling, he had seen 131313 cinder cone volcanoes, 181818 shield volcanoes, and 666 stratovolcanoes. Use the observed frequencies to create a probability model for Eitan randomly selecting one volcano in the world on which to conduct an extensive study. Input your answers as fractions or as decimals rounded to the nearest hundredth. Type of volcano Estimated probability Cinder cone 1/13 Shield Stratovolcano

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
