(0.25,0.40). Written in interval notation. It can be any number greater than 1/4 but less that 4/10.
Answer:
First Integer = 16
Second Integer = 18
Third integer = 20
Step-by-step explanation:
An even integer is represented by 2n
Where n is any integer
Let :
First Integer = 2n - 2
Second Integer = 2n
Third integer = 2n + 2
The sum of three even consecutive numbers = 2n - 2 + 2n + 2n + 2
= 2n + 2n + 2n - 2 + 2 = 54
= 6n = 54
n = 54/6
n = 9
First Integer = 2n - 2 = 2(9) - 2
= 16
Second Integer = 2n = 2(9)
= 18
Third integer = 2n + 2 = 2(9) + 2
= 20
Part A)
The answer is b) this is qualitative because the responses are about whether people are satisfied or not, instead of something numeric.
Part B)
The answer is b) this is random because it represents a different person in the sample, and it is variable because people feel differently about their situations.
