Eliza is at least twice as old as her friend's younger sister, Wendy. Which inequality correctly represents Eliza's age, e, compared with Wendy's age, w?

e ≥ 2w

Step-by-step explanation:

To make this easier, let us consider the case of Eliza being exactly twice as old as wendy

that would mean that twice the age of Wendy is the age of Eliza

e = 2w

but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy

Hence, the symbol '=' will be replaced by '≥'

Hence, the correct relation is

e ≥ 2w

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%
