Ten students are chosen from a statistics class of 22 students. Let X be the number who got an "A" in the class. Is this a binomial distribution, and if so, what is the number of trials?

Yes, this is a Binomial distribution, and the number of trials is 10.

Step-by-step explanation:

From the given information:

We are being told that ten students are chosen from a statistics class of 22 students.

If X represents the random variable for the number of students who got an "A" in the class.

Then we have two possible outcomes;

Number of students that got an "A" = (Success)

Number of students that did not get an "A" = (Failure)

Thus,  this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
