Answer:
50%.
Step-by-step explanation:
Dado que hay 12 canicas en una bolsa y 6 de ellas son verdes, para determinar la probabilidad de que si se elige una canica al azar, esta sea verde, se debe realizar el siguiente cálculo:
6 / 12 = X
0.5 = X
0.5 = 50/100
50/100 = 50%
Así, hay un 50% de probabilidades de que, eligiendo una canica al azar dentro de la bolsa, la canica elegida sea verde.
Answer:
f(x) = 3x² - 6x + 12
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Expand by FOIL (First Outside Inside Last)
- Standard Form: f(x) = ax² + bx + c
- Vertex Form: f(x) = a(bx + c)² + d
Step-by-step explanation:
<u>Step 1: Define function</u>
Vertex Form: f(x) = 3(x - 1)² + 9
<u>Step 2: Find Standard Form</u>
- Expand by FOILing: f(x) = 3(x² - 2x + 1) + 9
- Distribute 3: f(x) = 3x² - 6x + 3 + 9
- Combine like terms (constants): f(x) = 3x² - 6x + 12

Answer:
Histogram
Step-by-step explanation:
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.
