Answer:
Domain all real numbers Range (3,6,12,24,48)
Step-by-step explanation:
The domain is all real numbers so its either the first one or the second one. The range is multiplyed by 2 so the range is 3,6,12,24,48
9514 1404 393
Answer:
- ABHGEFDCA
- does not exist
- ECBADFE
Step-by-step explanation:
A Hamiltonian circuit visits each node once and returns to its start. There is no simple way to determine if such a circuit exists.
__
For graph 2, if there were a circuit, paths ACB, ADB, and AEB would all have to be on it. Inclusion of all of those requires visiting nodes A and B more than once, so the circuit cannot exist.
__
For graph 3, the circuit must include paths BAD and DFE. That only leaves node C, which can be reached from both nodes B and E, so path ECB completes the circuit.
Answer:
If x=1 then f(x)=-3
Step-by-step explanation:
Answer:
x = 6, y =-2
Step-by-step explanation:
5x+2y = 26
3x+2y = 14
Subtract the two equations to eliminate y
5x+2y = 26
-3x-2y = -14
---------------------
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
Now find y
3x+2y = 14
3*6+2y = 14
18+2y = 14
Subtract 18 from each side
18+2y-18 =14-18
2y = -4
Divide by 2
2y/2 = -4/2
y = -2
Answer:
B. NON-REPRESENTATIVE
Step-by-step explanation:
<em>The sample does not represent the population as a researcher is taking a sample from the hospital where the cholesterol level of the patient is generally high and the researcher is not randomly selecting the U.S. citizens.</em>
Thus, option (B) is correct.
Further, the sample is a subset of the population and it is easy to analyze as compared to the population.
The sample is said to be representative if it represents the whole population.
