The fraction of the plants that have flowers in the set given is calculated by dividing the number of plants with flowers by the total number of plants.
f = plants with flowers / total number of plants
From the given,
f = 4 / 5
f = 0.8
Thus, the answer to this item is the first choice.
Sort of..
The mean is all the numbers added together then divided by the amount of numbers there were.
Ex~1,2,3,4,5
Add them all together: 15
Divide by 5 because there is five numbers 15/5=3
The median is the middle number once you put then in order from smallest to largest (or the other way around).
Ex~ 3,5,2,4,1
Rearrange: 1,2,3,4,5
Find the Middle: 3
The median is 3 because it is in the middle of them all once you put them in smallest to largest.

81/100=0.81
So the answer is = 81/100
Answer:
Step-by-step explanation:
x^2-(2+2)x+4=0
or, x^2-2x-2x+4=0
or, x(x-2)-2(x-2)=0
or, (x-2)(x-2)=0
Now,
Either, x-2=0
=2
Or, x-2=0
=2
