Two hundreds total 200.
Fifteen tens together make 150.
Six ones equals the same.
Answer:
Expected counts: 55 ducks, 25 geese, 13 cranes, 11 swans, 6 herons
Observed counts:
61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons.
Step-by-step explanation:
Counting reveals there are 110 birds in total on the lake: 61+17+11+15+6.
The calculated 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 recorded were the observed counts.
For Mia's calculations, she should use y first because y signifies 22, while x indicates 4 dollars earned weekly.
Hi there!
While there are no answer choices provided, here's how you can solve a problem like this.
To find the average of two numbers, you simply sum them up and divide by two!
For instance, to find the midpoint between 1 and 3, you add 1 and 3 to get 4, then divide by 2 which results in 2!
For 100 and 580, adding gives you 680, and dividing by 2 results in 340!
The average between 0.57 and 0.69 involves adding to get 1.26, then dividing by 2 yields 0.63!
Now, with percentages, for 45% and 67%, the addition gives you 112%, and dividing that by 2 will result in 56%!
So, for your answer options, just calculate the total and divide by two to determine which one results in 76%!
I hope this information helps!
Answer:
A scale transformation that contracts and is subsequently followed by a reflection.
Step-by-step explanation:
A contraction with a scale factor less than 1, followed by a reflection, constitutes the combination of similarity transformations that maps polygon ABCD to polygon A'B'C'D.
