Answer:
She caught 10 rabbits
Step-by-step explanation:
Given
Represent Rabbits with R; Squirrels with S and Deer with D
Required
Determine the value of R
Solve for R
Recall that
Substitute 3D for S
Hence;
<em>She caught 10 rabbits</em>
The statement fourth "No, the flowers were not put into groups first and then randomly assigned the two additives would be correct.
<h3>What is random experiment?</h3>
Any well-defined method that yields an observable outcome that cannot be precisely predicted in advance is referred to as a random experiment. To avoid any ambiguity or surprise, a random experiment must be properly defined.
We have:
Total number of flowers selected = 20
And puts in each vase with same amount of water.
10 flowers have been assigned to receive the new additive.
The remaining 10 flowers receive the original additive.
Based on the data, this is not a randomized block design for the experiment because the flowers were not put into groups first and then randomly assigned the two additives.
Thus, the statement fourth "No, the flowers were not put into groups first and then randomly assigned the two additives would be correct.

Answer:
7 and 9 are alternate interior angles
Step-by-step explanation:
4 and 11 are corresponding angles
1 and 7 are vertical angles
Answer:
x = 111
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7 , then
sum = 180° × 5 = 900
Sum the interior angles and equate to 900
x + 139 + 121 + 125 + 126 + 158 + 120 = 900
x + 789 = 900 ( subtract 789 from both sides )
x = 111
