Can anybody help me plzz

G : C : A = 1 : 12 : 4

Step-by-step explanation:

Alex - A

George - G

Carl - C

A = G+12

C = 3A

A + G + C = 68

G : C : A = ?

A = G+12, --->  G = A - 12

C = 3A

A + G + C = 68 ---> A + A - 12 + 3A = 68  ---> 5A = 80 ---> A = 16

G = A - 12, G = 16 - 12 = 4, G = 4

C = 3A = 3*16 = 48, C = 48

G : C : A = 4 : 48 : 16 = 1 : 12 : 4

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.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
