PLEASE I ONLY HAVE 30 MIUNUTES TO FINISH When is choosing a sample from a population least likely to be appropriate? Select two options.
when the population is small
when the population is large
when the sample contains proportions of items/events/people that are different from those of the population
when the sample contains only items/events/people that reflect the population
when surveying the entire population is time consuming

When it is small & when the sample has things that are different from the population.

Step-by-step explanation:

A small sample has less chance of accurately reflecting a population & too many variables can also negatively influence the study.

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
