Determine whether ⊆,⊂, both, or neither can be placed in each blank to form a true statement. A={x|x∈N and 3

A⊆B

Step-by-step explanation:

⊆ = subset

⊂ = Proper subset

Subset: A is subset of B  if one or more than one or all elements of B is also element of A.

A⊆B

Proper subset: At least one element of B is not an element of A.

A⊂B

A={x|x∈N and 3<x<10]

3<x<10 means all natural number between 3 and 10.

Then A={4,5,6,7,8,9}

And B= the set of natural number between 3 and 10

B={4,5,6,7,8,9}

Since set A contains all element of B. Then A is subset of B

A⊆B
