20 POINTS Rochelle is taking soil samples. For each of the samples she takes, she will use 0.2 of the sample for testing. Match the sample sizes to the amounts that will be used for testing.

Number 1 is 1.6 if I'm right.

Step-by-step explanation:

To do the rest, divide the number by 0.2, because she is taking 0.2 of the amount used for testing.

Hope this helps!

1. 1.6 kg

2. 0.68 kg

3. 0.6 kg

4. 1.28 kg

Step-by-step explanation:

For all of the questions, you divide it by what she takes off the sample for testing.

Hope this helps :)

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.
