Answer:
0.8239 is the population proportion of participants that tried quitting smoking.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 142
Participants that tried quitting smoking = 117
Parameter:
- A parameter is a numerical value that describes a population.
Population proportion can be calculated as:
0.8239 is the population proportion of participants that tried quitting smoking.
Before I distribute, I solve the inside first:
2/3[8(3)^2+6]
2/3[8(9)+6]
2/3[72+6]
2/3[78]
2*26= 52 is the answer
another way:
2/3[8(3)^2+6]
2/3[8(9)+6]
2/3[72+6]
(2/3)*72+(2/3)*6
2*24+2*2
48+4= 52
Answer:
D. Yes The Triangles ARE ≅
Step-by-step explanation:
By definition equilateral triangles have all equal angles and sides. Since they share a side that means one of each triangle's sides are congruent. Using the transitive property (if side a ≅ side b and side b ≅ side c, then side a ≅ side c), you can prove that all other sides are congruent or equal in measure, no matter how you pair them.
