Answer:
The standard deviation is 0.1104. The 10% condition is met because it is very likely there are more than 200 minnows in the pond.
Step-by-step explanation:
The standard deviation for a proportion is:
σ = √(pq/n)
where p is the proportion, q is 1−p, and n is the sample size.
σ = √(0.58 × 0.42 / 20)
σ = 0.1104
Since the pond is large, there's probably more than 200 minnows, so the 10% condition is met.

Answer:
Step-by-step explanation:
12). Pair of supplementary angles means sum of the measures of a pair angles = 180°
So the three pairs will be,
m∠JKP + m∠JKL = 180°
m∠JKL + m∠LKM = 180°
m∠PKN + m∠NKL = 180°
13). Since obtuse angles measure more than 90°,
Two obtuse angles from the given picture will be,
∠JKL and ∠PKM
14). Since obtuse angles measure more than 90°, their sum will be more than 180°.
Therefore, two obtuse angles can never be supplementary.
