What is lnx+2lny−lnz written as a single logarithm?

Step-by-step explanation:

3 rules of logarithms that we are going to use on this is:

We can use the third rule to simplify the expression as:

Simplifying the first 2 terms using first rule gives us:

Now using the second rule to further simplify and write as single logarithm gives us:

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.

360/29
