In a lottery, numbered balls from 1 through 69 are placed into a spinning drum. Every 10 seconds a ball rolls down a tube to become one of the eight numbers to be drawn. At the end of the draw, the remaining 61 balls have an equally likely chance of becoming the bonus number. What is the name of this method of sampling?1. Simple random sampling
2. Systematic random sampling
3. Stratified random sampling
4. Convenience sampling

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

1) is right
