Answer:
Expected counts: 55 ducks, 25 geese, 13 cranes, 11 swans, 6 heron
Observed counts:
61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons.
Step-by-step explanation:
There are 61+17+11+15+6 = 110 birds on the lake.
The expected counts are:
0.50*110 = 55 ducks
0.23*110 = 25 geese
0.12*110 = 13 cranes
0.10*110 = 11 swans
0.05*110 = 6 herons
What the biologist counted were the observed counts.
15/45...divide both numbers by 15 = 1/3
Answer:
24
Step-by-step explanation:
8 times 3
Answer:
area= hieght times width
Step-by-step explanation:
area= hieght times width
I'm not sure which is which since you provided 3 different numbers but all you need to do is multiply the height and width and you have your answer.
Look to the picture for an example.
3r + 2rt = 18
r is the common factor
r(3 + 2t) = 18
r= 18/ 3 + 2t
r= 6 + 9t
Hope this helps!
