Check all that apply.

Hints

Check all that apply.

0,2,1,1/2

2,2,1,1/2

2,1,-1,1/2

2,-1,1,-1/2

2,0,0,-1/2

3,3,-2,-1/2

3,2,1,-1

4,3,5,-1/2

3,2,-1,-1/2

4,3,3,-1/2

1,2,0,1/2

1,0,0,-1/2

please i want the answer not the explaination?

Answer 1

for option 1:

n must be a positive number

n can't be 0

Hence, this is unacceptable

for option 2:

l must be less than n

Here value of n is 2

But value of l is 2

so, l can't be 2

Hence, this is unacceptable

for option 3:

This is Acceptable

for option 4:

l can't be negative

l can't be -1

Hence, this is unacceptable

for option 5:

This is Acceptable

for option 6:

l must be less than n

Here value of n is 3

But value of l is 3

so, l can't be 3

Hence, this is unacceptable

for option 7:

ms can be -1/2 or 1/2.

It can’t be -1

Hence, this is unacceptable

for option 8:

Value of l is 3

So, valid values of ml are [-3, -2, -1, 0, 1, 2, 3]

so, ml can't be 5

Hence, this is unacceptable

for option 9:

This is Acceptable

for option 10:

This is Acceptable

for option 11:

l must be less than n

Here value of n is 1

But value of l is 2

so, l can't be 2

Hence, this is unacceptable

for option 12:

This is Acceptable

Answer: option 3,5,9,10,12
