There were 2.8 million honeybee colonies in 2016 and 2.65 million in 2017. Whatpercent change is this?

Answer 1

1. -33.33%

2. 300%

3. -5.66%

Step-by-step explanation

The percent change is:

`\frac{\text{ final value - initial value}}{\text{ initial value}}*100`

1. The initial value here is 45 min, and the final value is 30min:

`(|30-45|)/(45)*100=\frac{\frac{}{\square}15}{45}*100=-0.3333*100=-33.33\text{ \%}`

-33.33% change means a 33.33% decrease.

2. The initial value is 0.5 hours and the final value is 2hours:

`(2-0.5)/(0.5)*100=(1.5)/(0.5)*100=3*100=300\text{ \%}`

3. The initial value is 2.8M and the final value is 2.65M:

`(2.65-2.8)/(2.65)*100=(-0.15)/(2.65)*100=-0.0566*100=-5.66\text{ \%}`

-5.66% change means a 5.66% decrease
