Answer:
b) f(3) is defined, but is not equal to the limit
Step-by-step explanation:
The portion of the function defined by the rational expression is equivalent to x/(x+3), which has a value of 1/2 at x=3. This is the limit of f(x) from the left or right as x approaches 3. However, the function is not defined at that point as 1/2. Rather, it is defined to be f(3)=1.
So, the limits at f(3) exist and are 1/2, but the function is defined as a different value there.
The only applicable statement is the second one.
Answer:
Dependent.
Quantitative.
Step-by-step explanation:
<u>Determine whether the sampling is dependent or independent.</u>
This is a matched-pair data test, as the same students are measured two times in order to compare the results.
This type of samples are dependent, as they are correlated between them.
<u>Indicate whether the response variable is qualitative or quantitative.</u>
The response variable is the test score. This is a quantitative variable, as this can be defined by a number. Both sample scores are averaged and compared.
Answer:
Axis of Symmetry: x = 3
Vertex: (3, 5)
Step-by-step explanation:
Use a graphing calc.
ellen had 44 per box and carl had 36 per box
but if they had only two boxes altogether then each box had 80 cans in it
