In a talent competition, half of the contestants are eliminated in each round. at the end of the nth round, 32 contestants remain. if there were 1,024 contestants at the start of the competition, what is the value of n?

Value of n = 6

Step-by-step explanation:

This is an example of Geometric progression.

First term, a  = 1024

Half of the contestants are eliminated in each round.

Common ratio, r = 0.5

We have n th term of GP

Substituting

At the end of the nth round, 32 contestants remain.

That is

Value of n = 6    

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
