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.
If 12 is 15% of a number than you could double 12 and get 24. The reason for this is because 15%*2 is 30% so than 12*2 would be 30% of a number. So 30% of a number is 24. If you than look at the 15% again you than will want to do 12*3 and get 46 as your answer.
The factors of 13m are 13 and m and it goes the same with 2n hope that helps.
Answer:
Ummm... ya its a becasue 95 is more then 50 (brainlest plzzzzzzzzzzzzzz)
Step-by-step explanation:
A straight line is 180. To find the angle of b, you minus 39 from 180.
