Suppose set a has 4 elements .what is the least number of elements a subset of a. can have

1 element

Step-by-step explanation:

Call B a set of n elements.

We can say that B is a subset of A if each element of B is also in A. This is written as:

B ⊆A

If a Set B contains all the elements of A, we can also say that B is a subset of A, where B = A.

Therefore, if set A has four elements, then for B to be a subset of A, the number of elements in B must be less than or equal to 4 but greater than 0. {1, 2, 3, 4}

Finally, according to the definition, B must have at least 1 element of A

answer: 800

step-by-step explanation:

explanation:

the loan estimate encourages consumers to shop. since it is the lenders who are required to issue a standardized loan estimate in a specific time frame, this way consumers are provided an opportunity to compare lenders and their products. otherwise consumer wouldn't know the benefits offered by other lenders.  

if a loan originator does not provide a loan estimate within 3 business days of receiving a completed loan application, that lender is in violation. lenders are required to issue a loan estimate within 3 days of applying for a loan or within 7 days prior to closing. having a loan estimate has following information.

not having loan estimate won't give you an idea of money to be borrowed.

you get to know your interest rates.

you also get to know if your interest rate can or may vary.

not having a good faith estimate can keep you unaware of aforementioned points.
