Given y = log3(x 4), what is the domain? x > –4 x < – 4 all real numbers.

vy

=

log

3

(

x

)

+

4

Set the argument in  

log

3

(

x

)

greater than  

0

to find where the expression is defined.

x

>

0

The domain is all values of  

x

that make the expression defined.

Step-by-step explanation:

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.
