The answer choice which represents the group which makes up the best sample for the researcher's survey as described in the task content is; Choice A; Parents of preschool children.
<h3>Which answer choice best represents a sample for the intended survey by Mrs Greenaway's researcher?</h3>
It follows from the task content that; Mrs. Greenaway has decided to open a new preschool in her town.
The need for a researcher therefore arises from the decision to either open the preschool or not.
Consequently, in a bid to choose a sample, Mrs. Greenaway's researcher must make sure the sample chosen is from the population space.
Therefore, answer choice A represents the correct sample.

There are 3.521 liters in 3521 milliliters
Answer:
MN = 3.03 ≈ 3
Step-by-step explanation:
Given: In ΔMNK MN = NK , m∠N = 110° and MK = 5.
To find: MN = ?
Sol: In ΔMNK,
∠M + ∠N + ∠K = 180° (sum of angles of a triangle)
2∠M = 180° - 110° ( ∠M =∠K since MN = MK)
∠M = 70°/2 = 35°
∴ ∠M = ∠K = 35°
Now, Using Sine Rule for finding sides,
Now ∵ sin 35° = 0.57 and sin 110° = 0.94 approx.
By substituting these values in above expression,
k = 
k = 3.03
Therefore, MN = 3 approx.
