FOR EDGE 2020 PEOPLE!!

Answer 2

week 1 < week 2

The graph in the attached figure

Explanation:

we know that

Week 1

The water level is 1.4 cm

Week 2

The water level is 1 1/2 cm

Convert to decimal number

Remember that

`1(1)/(2)=1+(1)/(2)=1+0.5=1.5\ cm`

Week 3

The water level is -2.1 cm

Compare the values of week 1 and week 2

1.4 cm is less than 1.5 cm

so

The symbol is <

1.4 < 1.5

week 1 < week 2
