All you have to do is plug in the given x values. your first equations would read:
f(-3) = 2^(-3)
f(-2) = 2^(-2)
f(-1) = 2^(-1)
these can be solved by moving decimal points or entering them into a calculator. regardless of the method, your answers are:
f(-3) = 0.002
f(-2) = 0.02
f(-1) = 0.2
so just repeat that process to fill in the rest of your table. to graph it, you'll use them as normal (x, y) points:
(-3, 0.002)
(-2, 0.02)
(-1, 0.2)
the graph might be a little difficult, working with such small values, but precision isn't totally important--0.002 will be super close to 0, 0.02 will be slightly further, 0.2 will be slightly further. the smaller values don't matter as much graphically and you'll recognize the graph of a growing exponential as you graph more of the table.
Excuse me but I’m going to need to see the multiple choices?
Answer:
-Conducting the survey on a holiday weekend will not produce representative results
-The survey was conducted using six similar flights
-The survey would not be a true representation of the entire population of air travelers
Step-by-step explanation:
First of all, the sampling method that was used in this survey/study was a convenience sampling, were they just used the data that was readily available, which in this case were the 6 flights from Boston to Salt Lake City.
This sampling method is useful for pilot studies and for identifying tendencies, however, the obtained sample is not representative of the population, and because there is no criteria to organize the sample, (for example there was no fight with a different route taking into account) it is impossible to obtain statistical results that are precise.
And besides that, the fact that the survey was carried out over Thanksgiving weekend is also a factor that can directly affect the results, so it needs to be taken into account as a variable, which in this study was not.
Answer:
y=24
Step-by-step explanation:
Straight line = 180°
collect like terms.
7y+12=180°
-12. - 12
7y=168°
÷7. ÷7
y=24
