Answer:
A) Yes
B) No
C) No
D) No
Step-by-step explanation:
A) Yes, every telephone number that could occur in that community will have an equal chance of being generated because the telephone numbers were generated randomly.
B) No, this method of generating telephone numbers would not result in a simple random sample (SRS) of local residences because the first three digits were generated in a different random way than the last four digits.
C) No, this method would not generate an SRS of local voters because not everybody will be pick up when they call because they may not be at home or they may be too busy to pick up.
D) No, this method is not unbiased in generating samples of households because there will be nonresponse bias since not everyone will pick up the call
Answer:
Domain: (-infinite, -8) U (-8, 2) U (2, +infinite)
Step-by-step explanation:
The graphs never intersect with the lines x=-8 and x=2 so -8 and 2 cannot be included in the domain.
Use "[]" for included and "()" for excluded.
The domain will go from far left to -8 => (-infinite, -8).
Then, the domain will go from -8 to 2 => (-8, 2).
Last, the domain will go from 2 to +infinite => (2, +infinite).
If you're trying to find the length of line AC, all you have to do is add the length of AB to the length of BC:
<span>AC=AB+BC </span>
<span>AC=5cm+√200cm </span>
<span>AC~5cm+14.14cm </span>
<span>AC=19.14cm </span>
Answer:
The function has been flipped due to the negative in front.
The function has been shifted 17 units to the left.
The function has been shifted 4.3 units down.
Step-by-step explanation:
When functions are transformed there are a few simple rules:
- Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
- Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
- Multiplying the function by a number less than 1 compresses it towards the x-axis.
- Multiplying the function by a number greater than 1 stretches it away from the x-axis.
- Multiplying by a negative flips the graph.
The graph of 
compares to 
in the following ways:
The function has been flipped due to the negative in front.
The function has been shifted 17 units to the left.
The function has been shifted 4.3 units down.
