Answer:
In the model, Mateo's swimming frequency per week is illustrated by the...4 rectangles...
Each time Mateo swims at the pool, the distance he covers in miles is shown as the...2 shaded sections out of 3 in 1 rectangle.
The expression...8/12 x 2/3 can be used to calculate the overall distance that Mateo swims in a week, resulting in...4/9 miles.

I completed the quiz on i-ready:)
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.
