the distance an object falls varies as the square of time the object is in motion. If an object falls for 3 seconds, it will 144.9 ft. To estimate the height, a person drops a stone at edge and measure how long it takes for stone to reach base. If it takes 3.9 seconds, what is the height of cliff? If needed round one decimal.

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.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

table 3 represents a direct variation function. : )
