Assume that random guesses are made for 6 multiple choice questions on the SAT test so that there are in equal 6 trials each with probability of success correct given by P equal 0.5 find the indicated probability for the number of correct answers find the probability that the number of ex of correct answers is fewer than 4Assume that random guesses are made for 6 multiple choice questions on the SAT test so that there are in equal 6 trials each with probability of success correct given by P equal 0.55 the indicated probability for the number of correct answers find the probability that the number of ex of correct answers is fewer than 4

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

plz mark brainliest i took the test
