Jason decides to go hiking in a trail. the trail starts at a point which is 192ft below sea level. he starts at the beginning of the trail and hikes to a location on a trail that is 320 ft above sea level. what is the difference in elevation?

128ft in elevation

Step-by-step explanation:

so if 192 is sea lv. just subtract that from how high he went 320

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
